Problems solved by technology
However, because the light is too dark at night, it is often impossible to extract useful information from nighttime surveillance videos
[0003] At present, the solutions to the problem of poor video monitoring effect caused by dark night light include: lighting at night, using infrared cameras, etc., but the cost of infrared cameras is relatively high. When lighting, often some large places For example, when there is almost no traffic in exhibition venues, the lights are still brightly lit, causing serious waste of electric energy

Embodiment Construction
[0020] refer to figure 1 , a kind of intelligent auxiliary system for video surveillance proposed by the present invention, comprising:
[0021] The personnel judgment module is used to detect the surveillance video that monitors the target area frame by frame, and judges whether there are people in the target area according to the detection results. It is specifically used for: detecting the surveillance video that monitors the target area frame by frame. When the similarity between consecutive frames is less than the preset first similarity threshold, it is determined that there is a person in the target area.
[0022] In the specific scheme, the video frames of the monitoring video are detected frame by frame, and the similarity of two consecutive video frames is compared. When the similarity between the two consecutive frames in the monitoring video is less than the preset first similarity threshold, it means The similarity between two consecutive frames is small. At this...

The invention discloses an intelligent auxiliary system for video monitoring, which includes: a personnel judgment module, which is used to detect the monitoring video of monitoring the target area frame by frame, and judge whether there is a person in the target area according to the detection result; When judging whether there is a person in the target area, extract the outline of the target person in the surveillance video; the comparison module is used to compare the outline of the target person with the preset comparison human outline, and judge whether the target area is in a dark period according to the comparison result ; The lighting module is used to illuminate the target area when it is judged that the target area is in a dark period.
Description
technical field [0001] The invention relates to the technical field of video monitoring, in particular to an intelligent auxiliary system for video monitoring. Background technique [0002] With the development of science and technology, many surveillance cameras are installed in many buildings and places, and 24-hour video surveillance is carried out on the main entrances and exits, aisles and halls, and the clarity is good. However, because the light is too dark at night, useful information cannot be extracted from the surveillance video at night in many cases. [0003] At present, the solutions to the problem of poor video monitoring effect caused by dark night light include: lighting at night, using infrared cameras, etc., but the cost of infrared cameras is relatively high. When lighting, often some large places For example, when there is almost no traffic in exhibition venues, the lights are still brightly lit, resulting in serious waste of electric energy. Contents...
