Embodiment 1

[0061] Such as figure 1 As shown, a video surveillance system provided by an embodiment of the present invention includes a surveillance camera 10, an environment detection unit 20, a video acquisition control unit 30, and a video database 40, wherein:

[0062] The monitoring camera 10 is used for collecting video data.

[0063] The environment detection unit 20 is used to detect the environmental parameter value of the external environment within the video range of the surveillance camera, and send it to the video acquisition control unit 30 .

[0064] The video acquisition control unit 30 is used to control the state of the monitoring camera 10 according to the environmental parameter value detected by the environmental detection unit 20, and associate the video data collected by the monitoring camera 10 with the corresponding environmental parameter value detected by the environmental detection unit 20 Stored in the video database 40.

[0065] The video database 40 is use...

Embodiment 2

[0073] Such as image 3 As shown, a monitoring video collection method provided in the embodiment of the present invention includes the following steps:

[0074] S101. Obtain at least one environmental parameter value of the external environment within the video range of the surveillance camera.

[0075] In this step, the environmental parameters include, but are not limited to: a combination of any two or more of sound parameters, light intensity parameters, infrared wave parameters, temperature parameters, or vibration parameters. Specifically, the external environment within the video range of the camera can be monitored in real time by detecting the environmental parameters within the video range of the camera, so as to determine whether there is a change in the video range, such as whether people, vehicles or animals appear within the video range, etc. Generally, one or more sensors are used to detect the environmental parameters within the video range of the camera.

Embodiment 3

[0083] Such as Figure 4 As shown, a surveillance video retrieval method provided by an embodiment of the present invention includes:

[0084] S201. Receive a target event input by a user.

[0085] The target event is a specific event, such as a car accident, an earthquake, a fire, etc. When these events occur, the values ​​of the corresponding environmental parameters such as vibration intensity, sound intensity, infrared wave parameters, and light intensity parameters will change. different. Of course the invention is not limited to these events.

[0086] S202. Extract an environmental parameter set according to the target event.

[0087] Specifically, when different target events occur, their surrounding environments are also different. According to different target events, values ​​of environmental parameters when the target events occur are extracted. For example, the environmental parameter set includes any combination of sound parameters, infrared wave parameters, v...

Abstract

The invention discloses a method and a device for acquiring surveillance video and a method and a device for retrieving the surveillance video, and belongs to the field of security. The method for retrieving the surveillance video includes receiving target events inputted by users; extracting environmental parameter sets according to the target events; retrieving video data from video databases according to the environmental parameter sets; searching for target events from the retrieved video data. The methods and the devices have the advantages that states of surveillance cameras can be controlled according to environmental parameter values in acquisition procedures, accordingly, the service lives of the cameras can be prolonged, and the quantities of invalid video data in the video databases can be greatly reduced, environmental parameters of the video data are stored in an association manner, and the follow-up video retrieval efficiency can be improved; the environmental parameters of the target events are used as keywords in retrieval procedures, accordingly, the surveillance video can be conveniently and quickly retrieved and invoked, and the video retrieval efficiency can be improved.

Description

technical field [0001] The invention relates to the security field, in particular to a monitoring video collection method, retrieval method and device. Background technique [0002] With the increase of social mobility and the increasingly complex structure of social groups, social security has become an increasingly prominent issue. Security video surveillance is currently a more effective means of security. Moreover, with the advancement of smart cities, surveillance cameras have spread all over the streets and alleys. Surveillance cameras have recorded a large amount of video data in real time, which not only effectively curbs some hidden dangers of crime, but also provides evidence of crimes, which brings great opportunities for the police to solve the case. Great convenience. However, the storage, retrieval and analysis of these massive video data often consume a lot of time and manpower. [0003] How to ignore a large amount of useless information in massive surveill...
