继续参考图2，示出了根据本申请的用于处理数据的方法的一个实施例的流程200。本实施例的用于处理数据的方法，包括以下步骤：Continuing to refer to FIG. 2 , aflow 200 of an embodiment of the method for processing data according to the present application is shown. The method for processing data in this embodiment includes the following steps:

步骤201，获取目标区域的视频数据和点云数据。Step 201, acquire video data and point cloud data of a target area.

本实施例中，用于处理数据的方法的执行主体(例如图1中所示的终端设备103或服务器105)可以通过各种方式获取目标区域的视频数据和点云数据。例如，执行主体可以通过网络从视频采集设备(例如图1中所示的视频采集设备102)处获取视频数据，从点云采集设备(例如图1中所示的点云采集设备101)处获取点云数据。这里，目标区域是指任意用于监测的区域，例如可以是施工区域、易发生故障的道路区域等。In this embodiment, the executing body of the method for processing data (for example, theterminal device 103 or theserver 105 shown in FIG. 1 ) can obtain video data and point cloud data of the target area in various ways. For example, the execution subject can acquire video data from a video acquisition device (for example, thevideo acquisition device 102 shown in FIG. point cloud data. Here, the target area refers to any area used for monitoring, for example, it may be a construction area, a road area prone to failure, and the like.

步骤202，根据视频数据中的至少一个视频帧，确定状态发生变化的对象。Step 202, according to at least one video frame in the video data, determine the object whose state has changed.

执行主体在获取到视频数据后，可以对视频数据中的至少一个视频帧进行分析，确定状态变化的对象。例如，执行主体可以分别比较相邻(例如第N帧和第N+1帧)或间隔预设数量视频帧(例如第N帧和第N+m帧)的两个视频帧，确定二者的差异，将差异指示的对象作为状态发生变化的对象。这里的状态发生变化可以是位置发生变化、体积发生变化、颜色发生变化等等。对象可以是任意需要监控的对象，例如可以包括落石、行人、文物等等。After the execution subject acquires the video data, it can analyze at least one video frame in the video data to determine the object whose state changes. For example, the execution subject can respectively compare two adjacent video frames (such as the Nth frame and the N+1th frame) or two video frames separated by a preset number of video frames (such as the Nth frame and the N+mth frame), and determine the difference between the two video frames. A diff that treats the object indicated by the diff as the object whose state changed. The change of state here may be a change of position, a change of volume, a change of color, and so on. The object can be any object that needs to be monitored, for example, it can include falling rocks, pedestrians, cultural relics, and so on.

步骤203，确定对象的目标点云数据。Step 203, determine the target point cloud data of the object.

在通过视频数据确定状态发生变化的对象后，可以确定对象的目标点云数据。具体的，执行主体可以结合点云数据和视频数据之间的转换关系，确定对象的目标点云数据。或者，执行主体可以直接对点云数据进行识别，确定出其中与上述对象对应的目标点云数据。After the object whose state has changed is determined from the video data, the target point cloud data of the object can be determined. Specifically, the execution subject can determine the target point cloud data of the object by combining the conversion relationship between point cloud data and video data. Alternatively, the execution subject may directly identify the point cloud data, and determine the target point cloud data corresponding to the above objects.

步骤204，根据目标点云数据，确定预设预警事件是否发生。Step 204, according to the target point cloud data, determine whether a preset early warning event occurs.

执行主体在确定各对象的目标点云数据后，可以判断预设预警事件是否发生。这里的预设预警事件可以包括但不限于：对象的移动距离超过了预设距离阈值、对象的颜色变成了预设颜色、对象经过了预设区域。After the execution subject determines the target point cloud data of each object, it can judge whether the preset early warning event occurs. The preset warning events here may include but are not limited to: the moving distance of the object exceeds a preset distance threshold, the color of the object changes to a preset color, and the object passes through a preset area.

步骤205，响应于确定预设预警事件发生，在视频数据中生成特效动画用于突出展示预设预警事件。Step 205, in response to determining that the preset warning event occurs, generate a special effect animation in the video data for highlighting the preset warning event.

如果执行主体确定预设预警事件发生，则可以在视频数据中生成特效动画用于突出展示预设预警事件。这里的特效动画可以是带有某种显示效果的动画，通过展示上述特效动画，用户可以直观地看出预设预警事件的发生。具体的，执行主体可以在视频数据的中心生成特效动画，并且特效动画的显示层级位于最上层。或者，执行主体可以在视频数据中对象的位置处生成特效动画，这样方便用户观察对象的位置。If the executive body determines that the preset early warning event occurs, a special effect animation can be generated in the video data to highlight the preset early warning event. The special effect animation here may be an animation with a certain display effect. By displaying the above special effect animation, the user can intuitively see the occurrence of the preset early warning event. Specifically, the execution subject may generate the special effect animation at the center of the video data, and the display level of the special effect animation is at the top. Alternatively, the execution subject may generate a special effect animation at the position of the object in the video data, which is convenient for the user to observe the position of the object.

继续参见图3，其示出了根据本申请的用于处理数据的方法的一个应用场景的示意图。在图3的应用场景中，通过在易发生落石的道路周围设置监控摄像头采集视频数据以及雷达传感器采集点云数据。通过对视频数据进行分析，确定出巨石的位置发生变化。通过点云数据，确定了巨石的目标点云数据。并根据目标点云数据，确定了巨石的移动距离为5cm，确定发生落石的可能性较大，则在视频数据中生成石头下落的特效动画。Continue referring to FIG. 3 , which shows a schematic diagram of an application scenario of the method for processing data according to the present application. In the application scenario shown in Figure 3, video data is collected by surveillance cameras and point cloud data is collected by radar sensors by setting surveillance cameras around roads prone to rockfall. By analyzing the video data, it was determined that the position of the boulder had changed. Through the point cloud data, the target point cloud data of the boulder is determined. And according to the target point cloud data, it is determined that the moving distance of the boulder is 5cm, and it is determined that the possibility of rockfall is high, and then a special effect animation of the falling stone is generated in the video data.

本申请的上述实施例提供的用于处理数据的方法，帮助人理解分析现实场景中人感觉不到但视频或点云可以感知到的事件的发生，提高人们对场景理解感知。The method for processing data provided by the above embodiments of the present application helps people to understand and analyze the occurrence of events in real scenes that people cannot perceive but can be perceived by video or point cloud, and improve people's understanding of the scene.

继续参见图4，其示出了根据本申请的用于处理数据的方法的另一个实施例的流程400。如图4所示，本实施例的方法可以包括以下步骤：Continue referring to FIG. 4 , which shows aflow 400 of another embodiment of the method for processing data according to the present application. As shown in Figure 4, the method of this embodiment may include the following steps:

步骤401，获取目标区域的视频数据和点云数据。Step 401, acquire video data and point cloud data of the target area.

步骤402，根据视频数据中的至少一个视频帧，确定状态发生变化的对象。Step 402: Determine an object whose state has changed according to at least one video frame in the video data.

步骤403，确定对象的目标点云数据。Step 403, determine the target point cloud data of the object.

步骤404，根据目标点云数据，识别对象的类型、移动方向以及移动距离；响应于确定对象的类型、移动方向以及移动距离满足预设条件，确定预设预警事件发生。Step 404, according to the target point cloud data, identify the type, moving direction and moving distance of the object; in response to determining that the type, moving direction and moving distance of the object meet the preset conditions, determine that a preset warning event occurs.

本实施例中，执行主体在确定对象的目标点云数据后，可以对其进行点云识别，确定对象的类型、移动方向以及移动距离。可以理解的是，在确定对象的移动方向以及移动距离时，需要比较至少两个点云帧。具体的，执行主体可以首先从目标点云数据中，确定出对象的位置发生变化前的一个点云帧。将该点云帧作为参考。然后将之后的至少一个点云帧与参考进行比较，确定出对象的移动方向以及移动距离。In this embodiment, after the execution subject determines the target point cloud data of the object, it can perform point cloud recognition to determine the type, moving direction and moving distance of the object. It can be understood that at least two point cloud frames need to be compared when determining the moving direction and moving distance of the object. Specifically, the execution subject may first determine a point cloud frame before the position of the object changes from the target point cloud data. Use this point cloud frame as a reference. Then at least one subsequent point cloud frame is compared with the reference to determine the moving direction and moving distance of the object.

执行主体可以判断对象的类型、移动方向以及移动距离是否满足预设条件，如果满足，则认定预设预警事件发生。上述预设条件可以包括但不限于：行人向施工区域方向移动了50米、巨石下落了50厘米。The execution subject can judge whether the object type, moving direction, and moving distance meet the preset conditions, and if so, it is determined that the preset early warning event has occurred. The aforementioned preset conditions may include but are not limited to: pedestrians move 50 meters toward the construction area, and boulders fall 50 centimeters.

步骤405，根据目标点云数据，确定对象的三维位置信息；将三维位置信息投影到视频数据中的图像平面，确定对象的二维位置信息；根据二维位置信息，在视频数据中生成特效动画用于突出展示预设预警事件。Step 405, according to the target point cloud data, determine the three-dimensional position information of the object; project the three-dimensional position information to the image plane in the video data, determine the two-dimensional position information of the object; according to the two-dimensional position information, generate special effect animation in the video data Used to highlight preset early warning events.

本实施例中，执行主体可以首先根据目标点云数据，确定对象的三维位置信息。上述三维位置信息可以是三维坐标。然后，执行主体可以结合点云采集设备与视频采集设备之间的投影关系或坐标转换矩阵，将三维位置信息投影到视频数据中的图像平面，确定对象的二维位置信息。这里，二维位置信息即为对象在视频数据中的平面位置。执行主体可以在此平面位置处生成特效动画用于突出展示预设预警事件。In this embodiment, the execution subject may first determine the three-dimensional position information of the object according to the target point cloud data. The above three-dimensional position information may be three-dimensional coordinates. Then, the execution subject can combine the projection relationship or the coordinate transformation matrix between the point cloud acquisition device and the video acquisition device to project the three-dimensional position information onto the image plane in the video data to determine the two-dimensional position information of the object. Here, the two-dimensional position information is the plane position of the object in the video data. The executive body can generate a special effect animation at this plane position to highlight preset early warning events.

在本实施例的一些可选的实现方式中，执行主体具体可以通过图4中未示出的以下步骤来实现上述步骤405：响应于确定预设预警事件发生，根据对象的类型，确定对象的目标特效类型；根据目标特效类型，在视频数据中生成特效动画用于突出展示预设预警事件。In some optional implementations of this embodiment, the executive body may implement theabove step 405 through the following steps not shown in FIG. 4: in response to determining that a preset early warning event occurs, determine the Target special effect type; according to the target special effect type, special effect animation is generated in the video data to highlight preset warning events.

本实现方式中，如果预设预警事件发生，执行主体可以首先根据对象的类型，确定对象的目标特效类型。具体的，执行主体可以查询预先设定的对象类型与特效类型的对应关系，确定对象的目标特效类型。特效类型可以包括不同的显示颜色、不同的显现类型。例如，特效类型1是用于表示巨石落下的特效，其用红色表示巨石的颜色，用“飞出”这一显现方式来表示巨石的落下，同时用“哐当”声来表示巨石落地后发出的声音。执行主体可以在视频数据中生成上述目标特效类型的特效动画来突出展示预设预警事件。可以理解的是，执行主体可以在视频数据中对象的平面位置处生成上述特效动画。In this implementation, if a preset early warning event occurs, the execution subject may first determine the target special effect type of the object according to the type of the object. Specifically, the execution subject can query the preset correspondence between object types and special effect types to determine the target special effect type of the object. Special effect types may include different display colors and different presentation types. For example, special effect type 1 is a special effect used to represent a boulder falling. It uses red to represent the color of the boulder, uses the display method of "flying out" to represent the falling of the boulder, and uses "clang" to represent the sound of the boulder after it hits the ground. sound. The execution subject can generate the above-mentioned special effect animation of the target special effect type in the video data to highlight the preset early warning events. It can be understood that the execution subject may generate the above special effect animation at the plane position of the object in the video data.

在本实施例的一些可选的实现方式中，执行主体具体可以通过图4中未示出的以下步骤来实现上述步骤405：响应于确定预设预警事件发生，在视频数据中生成增强现实特效动画用于突出展示预设预警事件。In some optional implementations of this embodiment, the executive body may specifically implement theabove step 405 through the following steps not shown in FIG. 4: generating augmented reality special effects in the video data in response to determining that a preset warning event occurs Animations are used to highlight pre-set warning events.

本实现方式中，执行主体还可以在预设预警事件发生时，在视频数据中生成增强现实特效动画用于突出展示预设预警事件。执行主体可以采用现有的增强现实技术来生成增强现实特效动画。In this implementation, the executive body can also generate an augmented reality special effect animation in the video data to highlight the preset early warning event when the preset early warning event occurs. The executive body can use existing augmented reality technology to generate augmented reality animation with special effects.

本申请的上述实施例提供的用于处理数据的方法，可以对对象的类型、移动方向和移动距离进行监测，并在预警事件发生时以多种形式的醒目特效动画展示，从而方便用户观察和监管场景。The method for processing data provided by the above-mentioned embodiments of the present application can monitor the type, moving direction and moving distance of the object, and when an early warning event occurs, it will be displayed in various forms of eye-catching special effect animations, so as to facilitate users to observe and Regulatory scene.
