具体实施方式Detailed ways
为了使低级别权限的用户在观看前端设备的视频数据时，只能看到非遮挡区域的视频数据，无法看到遮挡区域的视频数据，一种实现方式是，在前端设备上对监控到的视频数据进行遮挡。当低级别权限的用户观看该前端设备的视频数据时，该前端设备发送的视频数据就是遮挡之后的视频数据，使得低级别权限的用户只能看到遮挡之后的视频数据。但是，在该方式下，当高级别权限的用户观看该前端设备的视频数据时，该前端设备发送的视频数据也是遮挡之后的视频数据，使得高级别权限的用户也只能看到遮挡之后的视频数据，无法看到遮挡区域的视频数据，影响高级别权限的用户的观看。In order to enable users with low-level authority to watch the video data of the front-end device, they can only see the video data in the non-occluded area and cannot see the video data in the occluded area. Video data is occluded. When a user with low-level authority watches the video data of the front-end device, the video data sent by the front-end device is the video data after blocking, so that the user with low-level authority can only see the video data after blocking. However, in this way, when a user with high-level authority watches the video data of the front-end device, the video data sent by the front-end device is also the video data after blocking, so that the user with high-level authority can only see the video data after blocking. For video data, the video data in the blocked area cannot be seen, which affects the viewing of users with high-level permissions.
为了使低级别权限的用户在观看前端设备的视频数据时，只能看到非遮挡区域的视频数据，无法看到遮挡区域的视频数据，另一种实现方式是，监控平台在收到来自监控终端的点播该前端设备的视频数据的请求消息时，获得对应用户的权限。针对低级别权限的用户，监控平台向监控终端发送遮挡之后的视频数据，使得低级别权限的用户只能看到遮挡之后的视频数据。针对高级别权限的用户，监控平台向监控终端发送未遮挡的视频数据，使得高级别权限的用户可以看到非遮挡区域的视频数据和遮挡区域的视频数据，即看到完整的视频数据。但是，在该方式下，需要监控平台获得对应用户的权限，并针对不同权限的用户进行不同处理，增大了监控平台的处理压力，影响监控平台的处理性能和稳定性。此外，监控平台只能向高级别权限的用户发送完整的视频数据，无法向低级别权限的用户发送完整的视频数据，这样，低级别权限的用户无法获得完整的视频数据，也无法将完整的视频数据提供给高级别权限的用户进行处理，只能等待高级别权限的用户来获得完整的视频数据，基于此，如果高级别权限的用户错过了完整的视频数据的获得时机，则可能导致完整的视频数据丢失，后续无法再获得完整的视频数据。In order to enable users with low-level authority to watch the video data of the front-end equipment, they can only see the video data in the non-occluded area and cannot see the video data in the occluded area. When the terminal requests a video data request message of the front-end device, it obtains the corresponding user's authority. For users with low-level permissions, the monitoring platform sends video data after occlusion to the monitoring terminal, so that users with low-level permissions can only see the video data after occlusion. For users with high-level authority, the monitoring platform sends unoccluded video data to the monitoring terminal, so that users with high-level authority can see the video data of the non-occluded area and the video data of the occluded area, that is, see the complete video data. However, in this way, the monitoring platform needs to obtain the permissions of the corresponding users and perform different processing for users with different permissions, which increases the processing pressure of the monitoring platform and affects the processing performance and stability of the monitoring platform. In addition, the monitoring platform can only send complete video data to users with high-level permissions, but cannot send complete video data to users with low-level permissions. In this way, users with low-level permissions cannot obtain complete video data, and cannot send complete Video data is provided to users with high-level authority for processing, and they can only wait for users with high-level authority to obtain complete video data. Based on this, if users with high-level authority miss the opportunity to obtain complete video data, it may cause complete The video data is lost, and the complete video data cannot be obtained later.
针对上述问题，本发明实施例中提出一种视频数据的显示方法，如图1所示，该视频数据的显示方法具体可以包括以下步骤：In view of the above problems, a method for displaying video data is proposed in an embodiment of the present invention. As shown in FIG. 1 , the method for displaying video data may specifically include the following steps:

步骤103，监控平台接收来自监控终端的点播前端设备的视频数据的请求消息，并将该前端设备对应的视频数据发送给监控终端；以使该监控终端获得指定用户的标识和前端设备的标识所对应的权限配置，并利用获得的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡，并向指定用户显示遮挡之后的视频数据。其中，当视频数据为用户A点播前端设备1时得到的视频数据时，指定用户的标识为用户A，前端设备的标识为前端设备1。Step 103, the monitoring platform receives the request message of the video data of the on-demand front-end equipment from the monitoring terminal, and sends the video data corresponding to the front-end equipment to the monitoring terminal; The corresponding permission configuration, and use the occlusion area information included in the obtained permission configuration to occlude the received video data, and display the occluded video data to the specified user. Wherein, when the video data is the video data obtained when the user A orders the front-end device 1, the identifier of the designated user is user A, and the identifier of the front-end device is the front-end device 1 .

Wherein, the time period type may specifically be periodic time or absolute time. Further, the occlusion area information specifically includes: upper-left coordinates of pixels, lower-left coordinates of pixels, upper-right coordinates of pixels, and lower-right coordinates of pixels.
本发明实施例中，监控平台在将指定用户对应的权限配置发送给监控终端之后，当为该指定用户分配的前端设备的遮挡区域信息发生变化时，则监控平台还可以生成包括该指定用户的标识、该前端设备的标识、以及变化后的遮挡区域信息的权限配置，并将变化后的权限配置发送给监控终端，以使该监控终端通过变化后的权限配置替换变化前的权限配置。In the embodiment of the present invention, after the monitoring platform sends the authority configuration corresponding to the designated user to the monitoring terminal, when the occlusion area information of the front-end device assigned to the designated user changes, the monitoring platform can also generate a ID, the ID of the front-end device, and the changed permission configuration of the masked area information, and send the changed permission configuration to the monitoring terminal, so that the monitoring terminal replaces the changed permission configuration with the changed permission configuration.
基于上述技术方案，本发明实施例中，通过在监控终端上保存权限配置，使得监控终端对收到的视频数据进行遮挡，并向指定用户显示遮挡之后的视频数据，当低级别权限的用户(即指定用户)观看前端设备的视频数据时，只能看到非遮挡区域的视频数据，无法看到遮挡区域的视频数据。上述方式不需要在前端设备上对视频数据进行遮挡的处理，从而不会影响前端设备的原始视频数据的存储，方便日后对遮挡区域的视频数据的回放以及对非遮挡区域的视频数据的回放。上述方式不需要在监控平台上对视频数据进行遮挡的处理，从而减轻监控平台的处理压力，并提高视频监控系统的整体性能。Based on the above technical solution, in the embodiment of the present invention, by saving the authority configuration on the monitoring terminal, the monitoring terminal blocks the received video data, and displays the blocked video data to the specified user, when the low-level authority user ( That is, when the specified user) watches the video data of the front-end device, he can only see the video data in the non-occluded area, but cannot see the video data in the occluded area. The above method does not need to block the video data on the front-end equipment, so it will not affect the storage of the original video data of the front-end equipment, and facilitates the playback of the video data in the covered area and the playback of the video data in the non-blocked area in the future. The above method does not need to block the video data on the monitoring platform, thereby reducing the processing pressure of the monitoring platform and improving the overall performance of the video monitoring system.
本发明实施例中提出一种视频数据的显示方法，如图2所示，该视频数据的显示方法具体可以包括以下步骤：A method for displaying video data is proposed in an embodiment of the present invention. As shown in FIG. 2 , the method for displaying video data may specifically include the following steps:

步骤202，监控终端向监控平台发送点播前端设备的视频数据的请求消息，并接收该监控平台发送的该前端设备对应的视频数据。In step 202, the monitoring terminal sends a request message for on-demand video data of the front-end device to the monitoring platform, and receives video data corresponding to the front-end device sent by the monitoring platform.
步骤203，监控终端获得该请求消息对应的指定用户的标识和前端设备的标识所对应的权限配置，并利用获得的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡，并向指定用户显示遮挡之后的视频数据。Step 203, the monitoring terminal obtains the authorization configuration corresponding to the identification of the specified user corresponding to the request message and the identification of the front-end device, and uses the occlusion area information included in the obtained authorization configuration to block the received video data, and sends the specified The user displays the video data after occlusion.
其中，当用户A点播前端设备1的视频数据时，则监控终端向监控平台发送的请求消息中，会携带用户A(指定用户的标识)和前端设备1(前端设备的标识)的相关信息，且监控平台会将前端设备1对应的视频数据发送给监控终端，而监控终端可以获得用户A和前端设备1所对应的权限配置。Wherein, when the user A orders the video data of the front-end device 1, the request message sent by the monitoring terminal to the monitoring platform will carry the relevant information of the user A (identification of the designated user) and the front-end device 1 (identification of the front-end device), And the monitoring platform will send the video data corresponding to the front-end device 1 to the monitoring terminal, and the monitoring terminal can obtain the permission configuration corresponding to the user A and the front-end device 1 .
本发明实施例中，权限配置中还可以包括时间段类型和时间点范围，该时间段类型具体可以为周期性时间或者绝对时间。进一步，遮挡区域信息具体包括：像素左上坐标、像素左下坐标、像素右上坐标、像素右下坐标。In the embodiment of the present invention, the permission configuration may also include a time period type and a time point range, and the time period type may specifically be periodic time or absolute time. Further, the occlusion area information specifically includes: upper-left coordinates of pixels, lower-left coordinates of pixels, upper-right coordinates of pixels, and lower-right coordinates of pixels.
基于此，监控终端利用获得的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡的过程，具体可以包括但不限于如下方式：监控终端在获得的权限配置中包括的时间段类型和时间点范围所对应的时间区间内，利用获得的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡。Based on this, the monitoring terminal uses the masking area information included in the obtained permission configuration to block the received video data. Specifically, it may include but not limited to the following methods: the monitoring terminal includes the time period type and In the time interval corresponding to the range of time points, the received video data is blocked by using the blocking area information included in the obtained permission configuration.
本发明实施例中，在监控终端接收来自监控平台的权限配置，并保存该权限配置之后，当为指定用户分配的前端设备的遮挡区域信息发生变化时，则监控终端还可以接收来自监控平台的变化后的权限配置，并通过变化后的权限配置替换变化前的权限配置；其中，变化后的权限配置中包括该指定用户的标识、该前端设备的标识、以及变化后的遮挡区域信息。In the embodiment of the present invention, after the monitoring terminal receives the permission configuration from the monitoring platform and saves the permission configuration, when the occlusion area information of the front-end equipment assigned to the specified user changes, the monitoring terminal can also receive the permission configuration from the monitoring platform.

本发明实施例中，在监控终端利用变化前的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡的过程中，如果监控终端收到变化后的权限配置，并通过变化后的权限配置替换了变化前的权限配置，则监控终端利用变化后的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡。In the embodiment of the present invention, when the monitoring terminal blocks the received video data by using the occlusion area information included in the authority configuration before the change, if the monitoring terminal receives the changed authority configuration and passes the changed authority If the configuration replaces the permission configuration before the change, the monitoring terminal blocks the received video data by using the masked area information included in the changed permission configuration.

步骤301，监控平台获得为指定用户分配的前端设备的遮挡区域信息，并生成指定用户对应的包括指定用户的标识、前端设备的标识、遮挡区域信息的权限配置。In step 301, the monitoring platform obtains the shielded area information of the front-end equipment assigned to the designated user, and generates an authority configuration corresponding to the designated user, including the designated user's identifier, the front-end device's identifier, and shielded area information.
其中，指定用户是指低级别权限的用户。可以由管理员在监控平台上为指定用户分配前端设备的遮挡区域信息，也可以由高级别权限的用户在监控平台上为指定用户分配前端设备的遮挡区域信息。基于管理员或者高级别权限的用户的配置，监控平台可以获得为指定用户分配的前端设备的遮挡区域信息。例如，高级别权限的用户在监控平台上为指定用户1分配前端设备1的遮挡区域信息1，并在监控平台上为指定用户1分配前端设备2的遮挡区域信息2。则监控平台获得为指定用户1分配的前端设备1的遮挡区域信息1，并生成包括指定用户1的标识、前端设备1的标识、遮挡区域信息1的权限配置1，并获得为指定用户1分配的前端设备2的遮挡区域信息2，并生成包括指定用户1的标识、前端设备2的标识、遮挡区域信息2的权限配置2。Among them, the specified user refers to a user with low-level authority. The shielding area information of the front-end equipment can be assigned to designated users by the administrator on the monitoring platform, or the shielding area information of the front-end equipment can be assigned to designated users by users with high-level authority on the monitoring platform. Based on the configuration of the administrator or a user with high-level authority, the monitoring platform can obtain the information of the shielded area of the front-end equipment assigned to the specified user. For example, a user with a high-level authority assigns the occlusion area information 1 of the front-end device 1 to the designated user 1 on the monitoring platform, and assigns the occlusion area information 2 of the front-end device 2 to the designated user 1 on the monitoring platform. Then the monitoring platform obtains the occlusion area information 1 of the front-end device 1 assigned to the specified user 1, and generates the authority configuration 1 including the identification of the specified user 1, the identification of the front-end device 1, and the occlusion area information 1, and obtains the allocation for the specified user 1. The masked area information 2 of the front-end device 2, and the authority configuration 2 including the identification of the specified user 1, the ID of the front-end device 2, and the blocked area information 2 is generated.
本发明实施例中，权限配置中还可以包括时间段类型和时间点范围，该时间段类型具体可以包括但不限于周期性时间或者绝对时间，且权限配置在时间段类型和时间点范围对应的时间区间生效。例如，时间段类型为周期性时间，时间点范围为每日的02:00-03:00时，则权限配置在每日的02:00-03:00生效。时间段类型为周期性时间，时间点范围为每周的星期一时，则权限配置在每周的星期一生效。时间段类型为绝对时间，时间点范围为2015.6.10至2015.6.11时，则权限配置只在2015.6.10至2015.6.11生效。In the embodiment of the present invention, the permission configuration may also include a time period type and a time point range. The time period type may specifically include but is not limited to periodic time or absolute time, and the permission configuration corresponds to the time period type and time point range. The time interval takes effect. For example, if the time period type is periodic time, and the time point range is 02:00-03:00 every day, the permission configuration takes effect at 02:00-03:00 every day. When the time period type is periodic time and the time point range is every Monday, the permission configuration takes effect on every Monday. When the time period type is absolute time and the time point range is from 2015.6.10 to 2015.6.11, the permission configuration will only take effect from 2015.6.10 to 2015.6.11.
本发明实施例中，遮挡区域信息具体可以包括但不限于：像素左上坐标、像素左下坐标、像素右上坐标、像素右下坐标。基于上述四个坐标点，可以确定一个唯一的遮挡区域，该遮挡区域的形状可以基于实际情况选择。In the embodiment of the present invention, the occlusion area information may specifically include but not limited to: upper left coordinates of pixels, lower left coordinates of pixels, upper right coordinates of pixels, and lower right coordinates of pixels. Based on the above four coordinate points, a unique occlusion area can be determined, and the shape of the occlusion area can be selected based on actual conditions.
如表1和表2所示，分别为权限配置1和权限配置2的一种示例。As shown in Table 1 and Table 2, they are an example of permission configuration 1 and permission configuration 2 respectively.
表1Table 1
表2Table 2
步骤302，监控平台获得指定用户对应的监控终端(即指定用户使用的监控终端)，并将该指定用户对应的权限配置发送给该监控终端。Step 302, the monitoring platform obtains the monitoring terminal corresponding to the designated user (ie, the monitoring terminal used by the designated user), and sends the authorization configuration corresponding to the designated user to the monitoring terminal.
步骤303，监控终端接收来自监控平台的权限配置，并保存该权限配置。Step 303, the monitoring terminal receives the permission configuration from the monitoring platform, and saves the permission configuration.
其中，在指定用户使用监控终端登录到监控平台时，监控平台可以获得指定用户与监控终端之间的对应关系，或者，在指定用户使用监控终端向监控平台发送点播视频数据的请求消息时，监控平台可以获得指定用户与监控终端之间的对应关系。例如，监控平台获得指定用户1与监控终端1之间的对应关系，并将指定用户1对应的权限配置1和权限配置2发送给监控终端1，由监控终端1在本监控终端1上保存权限配置1和权限配置2。Wherein, when a designated user logs in to the monitoring platform using a monitoring terminal, the monitoring platform can obtain the corresponding relationship between the designated user and the monitoring terminal, or, when the designated user uses a monitoring terminal to send a request message for on-demand video data to the monitoring platform, the monitoring The platform can obtain the corresponding relationship between the specified user and the monitoring terminal. For example, the monitoring platform obtains the corresponding relationship between the designated user 1 and the monitoring terminal 1, and sends the authority configuration 1 and authority configuration 2 corresponding to the designated user 1 to the monitoring terminal 1, and the monitoring terminal 1 saves the authority on the monitoring terminal 1. Configuration 1 and permission configuration 2.
本发明实施例中，监控平台将指定用户对应的权限配置发送给监控终端后，当为该指定用户分配的前端设备的遮挡区域信息发生变化时，监控平台还可以生成包括该指定用户的标识、该前端设备的标识、以及变化后的遮挡区域信息的权限配置，并将变化后的权限配置发送给监控终端。监控终端在接收到变化后的权限配置时，通过变化后的权限配置替换变化前的权限配置。In the embodiment of the present invention, after the monitoring platform sends the authority configuration corresponding to the specified user to the monitoring terminal, when the occlusion area information of the front-end equipment assigned to the specified user changes, the monitoring platform can also generate an identification including the specified user, The identity of the front-end device and the changed permission configuration of the masked area information are sent to the monitoring terminal. When the monitoring terminal receives the changed authority configuration, it replaces the authority configuration before the change with the changed authority configuration.
其中，管理员或者高级别权限的用户在监控平台上为指定用户分配前端设备的遮挡区域信息之后，管理员或者高级别权限的用户还可以在监控平台上，修改为该指定用户分配的该前端设备的遮挡区域信息。Among them, after an administrator or a user with a high-level authority assigns the shielded area information of the front-end device to a designated user on the monitoring platform, the administrator or a user with a high-level authority can also modify the front-end equipment assigned to the designated user on the monitoring platform. Information about the occlusion area of the device.
例如，高级别权限的用户在监控平台上为指定用户1分配前端设备1的遮挡区域信息1之后，如果将遮挡区域信息1修改为遮挡区域信息3，则监控平台获得为指定用户1分配的前端设备1的遮挡区域信息1发生变化，并生成包括指定用户1的标识、前端设备1的标识、遮挡区域信息3的权限配置1，并将变化后的权限配置1发送给监控终端1。监控终端1在接收到变化后的权限配置1时，通过变化后的权限配置1(遮挡区域信息为遮挡区域信息3)替换变化前的权限配置1(遮挡区域信息为遮挡区域信息1)。For example, after a user with a high-level authority assigns the occlusion area information 1 of the front-end device 1 to the specified user 1 on the monitoring platform, if the occlusion area information 1 is changed to the occlusion area information 3, the monitoring platform will obtain the front-end equipment assigned to the specified user 1. The occlusion area information 1 of the device 1 changes, and generates an authority configuration 1 including the identification of the specified user 1, the identification of the front-end device 1, and the occlusion area information 3, and sends the changed authority configuration 1 to the monitoring terminal 1. When the monitoring terminal 1 receives the changed authority configuration 1, the changed authority configuration 1 (occlusion area information is the occlusion area information 3) replaces the pre-change authority configuration 1 (the occlusion area information is the occlusion area information 1).
步骤304，监控终端向监控平台发送点播前端设备的视频数据的请求消息，由监控平台接收来自监控终端的点播前端设备的视频数据的请求消息。Step 304 , the monitoring terminal sends a request message for video data of the on-demand front-end equipment to the monitoring platform, and the monitoring platform receives a request message for video data of the on-demand front-end equipment from the monitoring terminal.
步骤305，监控平台将该前端设备对应的视频数据发送给监控终端，由监控终端接收该监控平台发送的该前端设备对应的视频数据。Step 305, the monitoring platform sends the video data corresponding to the front-end device to the monitoring terminal, and the monitoring terminal receives the video data corresponding to the front-end device sent by the monitoring platform.
其中，监控终端向监控平台发送点播前端设备的视频数据的请求消息的过程，可以为实时视频数据的点播过程，也可以为视频数据的回放过程。Wherein, the process of the monitoring terminal sending the request message of requesting video data of the front-end equipment to the monitoring platform may be a process of requesting real-time video data, or a process of playing back video data.
针对实时视频数据的点播过程，当前端设备在监控平台注册成功后，监控平台可以预请求前端设备的视频数据，前端设备将视频数据发送到监控平台，由监控平台接收该前端设备的视频数据。在之后的过程中，如果监控终端向监控平台发送点播该前端设备的视频数据的请求消息，则监控平台将该前端设备对应的视频数据发送给监控终端，由监控终端接收视频数据。For the on-demand process of real-time video data, after the front-end device is successfully registered on the monitoring platform, the monitoring platform can pre-request the video data of the front-end device, and the front-end device sends the video data to the monitoring platform, and the monitoring platform receives the video data of the front-end device. In the subsequent process, if the monitoring terminal sends a request message to the monitoring platform to order the video data of the front-end device, the monitoring platform sends the video data corresponding to the front-end device to the monitoring terminal, and the monitoring terminal receives the video data.
其中，监控平台在接收到前端设备的视频数据时，基于实际配置，监控平台还可以存储前端设备的视频数据，以在后续视频数据的回放过程中，将存储的前端设备的视频数据发送给点播该前端设备的视频数据的监控终端。Among them, when the monitoring platform receives the video data of the front-end equipment, based on the actual configuration, the monitoring platform can also store the video data of the front-end equipment, so as to send the stored video data of the front-end equipment to the VOD during the playback process of the subsequent video data. The video data monitoring terminal of the front-end equipment.
其中，监控平台可以在视频链路建立完成之后，基于监控终端的指定端口和IP地址，将前端设备对应的视频数据发送给监控终端。Wherein, the monitoring platform can send the video data corresponding to the front-end equipment to the monitoring terminal based on the designated port and IP address of the monitoring terminal after the video link is established.
针对视频数据的回放过程，如果监控终端向监控平台发送点播前端设备的视频数据的请求消息(回放请求消息)，则监控平台从已经存储的该前端设备的视频数据中，查询到相应时间段(请求消息中会携带点播的视频数据的时间段信息)的视频数据，并将查询到的视频数据发送给监控终端。For the playback process of the video data, if the monitoring terminal sends a request message (playback request message) of the video data of the on-demand front-end equipment to the monitoring platform, the monitoring platform queries the corresponding time period from the stored video data of the front-end equipment ( The request message will carry the video data of the time period information of the on-demand video data), and send the queried video data to the monitoring terminal.
本发明实施例的视频数据传输过程中，无论是前端设备发送给监控平台的视频数据，还是监控平台发送给监控终端的视频数据，均可以采用加密算法(如MD5(MessageDigest5，消息摘要第五版)算法等)对传输的视频数据进行加密处理，只有监控终端才可以对收到的视频数据进行解密处理，从而保证视频数据不被非法截获和查看，避免安全问题的发生。In the video data transmission process of the embodiment of the present invention, whether it is the video data sent by the front-end equipment to the monitoring platform, or the video data sent by the monitoring platform to the monitoring terminal, an encryption algorithm (such as MD5 (MessageDigest5, message digest fifth edition) can be used ) algorithm, etc.) to encrypt the transmitted video data, and only the monitoring terminal can decrypt the received video data, so as to ensure that the video data will not be illegally intercepted and viewed, and avoid the occurrence of security problems.
步骤306，监控终端在收到视频数据后，获得指定用户的标识和前端设备的标识所对应的权限配置，并利用获得的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡，并向指定用户显示遮挡之后的视频数据。Step 306: After receiving the video data, the monitoring terminal obtains the authorization configuration corresponding to the identification of the specified user and the identification of the front-end device, and uses the occlusion area information included in the obtained authorization configuration to block the received video data, and Display the video data after occlusion to the specified user.
例如，当指定用户1点播前端设备1的视频数据时，则指定用户的标识为指定用户1，前端设备的标识为前端设备1，且收到的视频数据为前端设备1的视频数据。监控终端从自身存储的指定用户1对应的权限配置1和权限配置2中，获得指定用户1和前端设备1所对应的权限配置1(如表1所示)，并利用权限配置1中包括的遮挡区域信息对收到的视频数据进行遮挡。For example, when the designated user 1 orders the video data of the front-end device 1, the designation of the designated user is the designated user 1, the identification of the front-end device is the front-end device 1, and the received video data is the video data of the front-end device 1. The monitoring terminal obtains the authority configuration 1 corresponding to the designated user 1 and the front-end device 1 (as shown in Table 1) from the authority configuration 1 and the authority configuration 2 corresponding to the designated user 1 stored in itself, and uses the rights included in the authority configuration 1. The occlusion area information occludes the received video data.
本发明实施例中，监控终端利用获得的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡的过程，具体可以包括但不限于如下方式：监控终端在获得的权限配置中包括的时间段类型和时间点范围所对应的时间区间内，利用获得的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡。In the embodiment of the present invention, the monitoring terminal uses the occlusion area information included in the obtained permission configuration to block the received video data. Specifically, it may include but not limited to the following methods: the monitoring terminal includes the time in the obtained permission configuration In the time interval corresponding to the segment type and time point range, the received video data is blocked by using the blocking area information included in the obtained permission configuration.
例如，基于表1所示的权限配置，监控终端在每日的02:00-03:00，利用像素左上坐标(1,2)、像素左下坐标(1,4)、像素右上坐标(3,2)、像素右下坐标(3,4)，对收到的视频数据进行遮挡，具体的遮挡方式在此不再赘述。For example, based on the permission configuration shown in Table 1, the monitoring terminal uses the upper left coordinates of pixels (1,2), the lower left coordinates of pixels (1,4), and the upper right coordinates of pixels (3, 2) The lower right coordinates (3,4) of the pixel block the received video data, and the specific blocking method will not be repeated here.
本发明实施例中，在监控终端利用变化前的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡的过程中，如果监控终端收到变化后的权限配置，并通过变化后的权限配置替换了变化前的权限配置，则监控终端利用变化后的权限配置中包括的遮挡区域信息对收到的视频数据进行遮挡。In the embodiment of the present invention, when the monitoring terminal blocks the received video data by using the occlusion area information included in the authority configuration before the change, if the monitoring terminal receives the changed authority configuration and passes the changed authority If the configuration replaces the permission configuration before the change, the monitoring terminal blocks the received video data by using the masked area information included in the changed permission configuration.
基于上述技术方案，本发明实施例中，至少具有以下优点：Based on the above technical solution, the embodiment of the present invention has at least the following advantages:
1、通过在监控终端上保存权限配置，使得监控终端对收到的视频数据进行遮挡，并向指定用户显示遮挡之后的视频数据，当低级别权限的用户(即指定用户)观看前端设备的视频数据时，则只能看到非遮挡区域的视频数据，无法看到遮挡区域的视频数据。当高级别权限的用户观看前端设备的视频数据时，则可以看到非遮挡区域的视频数据，也可以看到遮挡区域的视频数据。在上述方式下，在向低级别权限的用户显示视频数据时，只显示非遮挡区域的视频数据，而且，在存储视频数据时，存储的是完整的视频数据。1. By saving the permission configuration on the monitoring terminal, the monitoring terminal blocks the received video data and displays the blocked video data to the specified user. When data is displayed, only the video data in the non-occluded area can be seen, and the video data in the occluded area cannot be seen. When a user with a high-level authority watches the video data of the front-end device, he can see the video data of the non-blocking area, and can also see the video data of the blocking area. In the above manner, when displaying video data to users with low-level authority, only the video data in the non-occluded area is displayed, and when storing video data, what is stored is complete video data.
2、不需要在前端设备上对视频数据进行遮挡的处理，从而不会影响前端设备的原始视频数据的采集，不会影响前端设备的原始视频数据的存储，方便日后对遮挡区域的视频数据的回放以及对非遮挡区域的视频数据的回放。2. There is no need to occlude the video data on the front-end equipment, so that it will not affect the collection of the original video data of the front-end equipment, and will not affect the storage of the original video data of the front-end equipment, which is convenient for the video data of the occlusion area in the future Playback and playback of video data in non-occluded areas.
3、不需要在监控平台上对视频数据进行遮挡的处理，从而减轻监控平台的处理压力，并不影响监控平台的稳定性，并提高视频监控系统的整体性能。具体的，当多个用户有不同的遮挡区域权限，且这多个用户请求同一视频数据时，则监控平台不需要区分这多个用户的遮挡区域权限，可以向多个用户发送相同的视频数据，实现视频数据的复用、转发及存储，从而可以满足多个不同用户(3个以及以上)的不同遮挡区域权限的应用场景。3. There is no need to block the video data on the monitoring platform, thereby reducing the processing pressure of the monitoring platform, not affecting the stability of the monitoring platform, and improving the overall performance of the video monitoring system. Specifically, when multiple users have different occlusion area permissions and these multiple users request the same video data, the monitoring platform does not need to distinguish the occlusion area permissions of these multiple users, and can send the same video data to multiple users , realizing the multiplexing, forwarding and storage of video data, so as to meet the application scenarios of multiple different users (3 or more) with different occlusion area permissions.
4、监控平台既能向高级别权限的用户发送完整的视频数据，也能向低级别权限的用户发送完整的视频数据(只是监控终端在向低级别权限的用户显示视频数据时，是显示遮挡之后的视频数据)，这样，低级别权限的用户可以获得完整的视频数据。基于此，在网络环境不佳或者其他环境局限的情况下，低级别权限的用户可以先将完整的视频数据下载并保存起来，并在后续过程中提供给高级别权限的用户进行处理，由高级别权限的用户查看并分析视频数据，不需要等待高级别权限的用户来下载完整的视频数据，不需要高级别权限的用户重复下载完整的视频数据，从而避免完整的视频数据的丢失。4. The monitoring platform can not only send complete video data to users with high-level permissions, but also send complete video data to users with low-level permissions (only when the monitoring terminal displays video data to users with low-level permissions, it is displayed. subsequent video data), in this way, users with low-level permissions can obtain complete video data. Based on this, in the case of poor network environment or other environmental limitations, users with low-level authority can download and save the complete video data first, and provide it to users with high-level authority for processing in the subsequent process, and the high-level authority will Users with high-level permissions can view and analyze video data, and do not need to wait for users with high-level permissions to download complete video data. Users who do not need high-level permissions download complete video data repeatedly, thereby avoiding the loss of complete video data.
