Abstract
Description
Technical Field
The present invention relates to the field of video monitoring, and in particular, to a data merging processing method, apparatus, and system for video monitoring.
Background
At present, with the improvement of a social security system, video monitoring equipment is distributed in all corners, and when a law enforcement officer needs to identify a suspect, the suspect can be searched through a monitoring image. At present, suspects are identified through monitoring images mainly through a manual identification mode or a machine automatic identification mode, but the identification modes can only identify various image characteristics (such as human face characteristics, behavior characteristics, clothing characteristics, action characteristics, gait characteristics, driven vehicle characteristics and the like) appearing in the current monitoring images. However, the suspect is not usually in a static state, and leaves the current monitoring area, so that the problem of determining the direction of the suspect is solved.
For example, if a suspect is found in a surveillance image captured by a camera a installed in a location of a case at 5 pm, but the suspect leaves the field of view of the camera a at 5 pm and 10 pm, in order to determine the behavior of the suspect after 5 pm and 10 pm, it is generally necessary to manually check whether the suspect appears in the surveillance image captured by another camera installed near the camera a after 5 pm and 10 pm, and if the suspect is found in the surveillance image captured by the camera B, the corresponding surveillance image needs to be extracted for specific analysis. Under the conditions of complex road conditions, various cameras or unclear videos, the processing mode is time-consuming and labor-consuming.
Meanwhile, there may be a case where the suspect passes through the vicinity of the camera B after leaving the visual field range of the camera a, but the suspect does not appear in the visual field of the camera B due to the shooting angle of the camera B, so that the suspect cannot be found in the monitored image shot by the camera B, and the suspect disappears from the monitored image.
Further, due to the photographing angle of the camera a, although the suspect is in the spot, the suspect does not appear in the field of view of the camera a. In this case, the suspect cannot be found in time by merely recognizing the monitoring image.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 is a schematic diagram of an embodiment of a data merging processing method for video surveillance according to the present invention. Wherein:
Optionally, the electronic identity is a MAC address.
And 102, combining the electronic identity identification with corresponding audio information in the video image to generate a streaming media file, wherein the acquisition time of the electronic identity identification is synchronous with the acquisition time of the corresponding audio information.
For example, the acquisition time of a certain electronic identity is 15 points at 25/2016, while the acquisition time of a video image acquired by a video acquisition device is all day at 25/12/2016, and the acquisition time of corresponding audio information is 0 to 24 points at 25/12/2016, and the electronic identity and the audio information at 15 points at 25/12/2016 are merged through merging processing.
Based on the data merging processing method for video monitoring provided by the above embodiment of the present invention, the collected electronic identification is merged with the corresponding audio information in the video image to generate the streaming media file, wherein the collection time of the electronic identification is synchronized with the collection time of the corresponding audio information. Therefore, when the suspect is searched through the video monitoring image, the suspect can be tracked by using the electronic identity mark, the monitoring image shot by the plurality of cameras does not need to be manually checked, and the working efficiency is greatly improved.
Fig. 2 is a schematic diagram of another embodiment of a data merging processing method for video surveillance according to the present invention. The step of merging the electronic identity identifier with the corresponding audio information in the video image comprises:
Optionally, the specified sampling frequency is not greater than the sampling frequency of the audio information in the video image.
Optionally, before merging, a feature code is added to the quantized electronic identity in order to distinguish the electronic identity from the audio information. So that the decoder can recognize the electronic identification and sample the corresponding rule for decoding when decoding.
Optionally, according to the time information input by the user, the electronic identity and/or the video image corresponding to the input time information is inquired in the streaming media file. In addition, according to the electronic identification input by the user, the video image and/or the time information corresponding to the input electronic identification can be inquired in the streaming media file.
Therefore, monitoring video information in a specified time and electronic identification marks appearing in the monitoring area can be known quickly, or when certain electronic identification mark appears in which monitoring area can be known quickly, which is very beneficial to monitoring and locking suspects quickly.
For example, a suspect is found in a surveillance video shot by a camera a installed in a kitchen area at 5 pm, and the suspect leaves the visual field of the camera a at 5 o 'clock and 10 o' clock. By utilizing the method and the device, 5 electronic identifications (the 5 electronic identifications can be changed into a first electronic identification set) appearing in the monitoring area of the camera A at the moment of 5 points and 3 electronic identifications (the 3 electronic identifications can be changed into a second electronic identification set) appearing in the monitoring area of the camera A at the moment of 5 points and 10 points can be quickly obtained, the obtained first electronic identification set and the obtained second electronic identification set are intersected, and if only one electronic identification exists in the intersection, the electronic identification is the electronic identification of the suspect mobile terminal.
Aiming at the track of the suspect after 5 points and 10 minutes, the surveillance video shot by other cameras arranged near the camera A after 5 points and 10 minutes is not required to be manually checked, the obtained electronic identity of the suspect is only required to be searched, if the surveillance video shot by the camera B after 5 points and 10 minutes comprises the electronic identity of the suspect, namely, the suspect is shown to enter the surveillance area of the camera B from the surveillance area of the camera A, the surveillance video shot by the camera B can be directly called, the surveillance video shot by other cameras is not required to be checked, and the working efficiency is greatly improved.
Meanwhile, the invention also has the advantage that even if the suspect enters the monitoring area where the camera B is located, the suspect can be determined to enter the area even if the image of the suspect cannot be shot due to the shooting angle of the camera B, so that the track of the suspect is further monitored. Therefore, the suspect can be effectively tracked and monitored.
In addition, under the condition that the specified electronic identity appears in the streaming media file, alarm information can be sent to the management platform. That is, the suspect can be actively monitored by actively inquiring the electronic identification.
For example, the obtained electronic identity of the suspect can be input into the system, and when the electronic identity is found in the monitoring video, that is, the suspect is indicated to have flowed to the monitoring area, at this time, the suspect can be monitored in time by sending alarm information.
It should be noted that the specified electronic identity may or may not be targeted. If the electronic identity marks appear in the areas where no people should appear, the alarm can be given immediately.
For example, a suspect enters a mall and hide in a corner where a camera cannot shoot at business hours, and then comes out to steal when no person is in the mall at night. Since the suspect cannot be found from the monitoring video, a great potential safety hazard is brought. After the method is implemented, although no abnormity is found in the monitored image, the monitored video shot by a certain camera at the end of the business hours of the shopping mall comprises the electronic identity, and no person exists in the shopping mall at the moment, so that the fact that the person is hidden in the monitored area is indicated, and the method can give an alarm in time under the condition, and can effectively reduce the potential safety hazard.

Based on the data merging processing device for video monitoring provided by the above embodiment of the present invention, the collected electronic identification is merged with the corresponding audio information in the video image to generate the streaming media file, wherein the collection time of the electronic identification is synchronized with the collection time of the corresponding audio information. Therefore, when the suspect is searched through the video monitoring image, the suspect can be tracked by using the electronic identity mark, the monitoring image shot by the plurality of cameras does not need to be manually checked, and the working efficiency is greatly improved.
