Abstract

A method, apparatus and system for providing surveillance video information are provided. The method comprises: receiving a surveillance video; performing characteristic recognition on each video frame in said surveillance video to obtain characteristic information respectively corresponding to said each video frame; wherein, characteristic information corresponding to each video frame in an ith video clip of said surveillance video matches the ith target characteristic information of M pieces of target characteristic information; determining video-related information corresponding to the ith video clip; sending the video-related information corresponding to at least one video clip of M said video clips to a client unit. The technical solution described above provides a user with the video information relating to critical information such as a target person or object, thereby reducing the time and labor costs spent by the user in finding desired video information.

Claims

1. A method for providing surveillance video information, used in a video surveillance system, comprising:

receiving a surveillance video;

performing characteristic recognition on each video frame in the surveillance video to obtain characteristic information respectively corresponding to said each video frame;

wherein, characteristic information corresponding to each video frame in an ith video clip of the surveillance video matches ith target characteristic information of M pieces of target characteristic information, and a value range of i is [1, M];

determining video-related information corresponding to the ith video clip; and

sending video-related information corresponding to at least one video clip of M said video clips to a client unit.

2. The method for providing surveillance video information according to claim 1, wherein, the video-related information corresponding to the ith video clip comprises a video time period and/or video device information.

3. The method for providing surveillance video information according to claim 1, wherein, before sending video-related information corresponding to at least one video clip of M said video clips to a client unit, the method further comprises:

correlatively storing ith characteristic information corresponding to the ith video clip and video-related information corresponding to the ith video clip into a search database;

wherein, the ith characteristic information is characteristic information corresponding to a video frame which satisfies a preset condition in the ith video clip;

wherein sending video-related information corresponding to any video clip in the at least one video clip to a client unit specifically comprises;

determining characteristic information corresponding to the video frame which satisfies the preset condition in said any video clip according to an inquiry request input by a user via the client unit;

searching in the search database according to the characteristic information corresponding to the video frame which satisfies the preset condition in said any video clip, to obtain video-related information corresponding to said any video clip; and

sending the video-related information corresponding to said any video clip to the client unit.

4. The method for providing surveillance video information according to claim 3, wherein, the inquiry request comprises characteristic information corresponding to the video frame which satisfies the preset condition in said any video clip selected by the user via the client unit from all said ith characteristic information.

5. The method for providing surveillance video information according to claim 3, wherein, the inquiry request comprises an inquiry characteristic picture, and the step of determining characteristic information corresponding to the video frame which satisfies the preset condition in said any video clip according to an inquiry request input by a user via the client unit comprises:

determining inquiry characteristic information according to the inquiry characteristic picture; and

determining characteristic information matching the inquiry characteristic information in all said ith characteristic information as the characteristic information corresponding to the video frame which satisfies the preset condition in said any video clip.

6. An apparatus for providing surveillance video information, used in a video surveillance system, comprising a receiving module, a recognition module, a determination module, and a sending module;

wherein,

the receiving module is configured to;

receive a surveillance video;

the recognition module is configured to;

the determination module is configured to;

determine video-related information corresponding to the ith video clip; and

the sending module is configured to;

send video-related information corresponding to at least one video clip of M said video clips to a client unit.

7. The apparatus for providing surveillance video information according to claim 6, wherein, the video-related information corresponding to the ith video clip comprises a video time period and/or video device information.

8. The apparatus for providing surveillance video information according to claim 6, further comprising a storage module, wherein:

the storage module is configured to;

before the sending module sends video-related information corresponding to at least one video clip of M said video clips to a client unit, correlatively store ith characteristic information corresponding to the ith video clip and video-related information corresponding to the ith video clip into a search database;

wherein, the ith characteristic information is characteristic information corresponding to a video frame which satisfies a preset condition in the ith video clip;

for any video clip in the at least one video clip, the sending module comprises a determination unit and a searching unit, wherein;

the determination unit is configured to;
