Problems solved by technology

[0005] Because the camera itself cannot interpret images, traditional monitoring relies on manual interpretation, but the number of cameras in the monitoring system can be large, and people are prone to fatigue and burnout, so the effectiveness of traditional monitoring systems is often relatively low
[0006] The shooting angle of the camera is fixed. When suspicious situations are found, the traditional monitoring system needs to manually memorize and operate the dome camera to further check the close-up shots. Operation and control keyboards will not be equipped with a large number, so it is difficult to realize simultaneous coordination and supplementary shooting of multiple speed dome cameras, resulting in delays in capturing important incidents

example 1

[0049]Example 1: When the gun camera 203 finds someone entering from the window 105 through intelligent video analysis at night, the video analysis module generates an alarm and reports to the management system that an alarm has occurred in the defense area 3 of the camera 203. A hit entry shows that the camera is 201, and the management system will query the shooting status of 201. If the current status is idle and the lock flag is unlocked, the management program will fill in the importance, the calculated shooting time and the preset position information. The status value of 201, and start the re-shooting program of 201, and at the same time, the sound and light will raise the duty personnel. The status table of 201 at this time is as follows.

Abstract

The invention discloses a video-analysis-based box and dome camera linkage method. After a box camera protection area is discovered to be abnormal, dome cameras are automatically arranged for complementary shooting according to importance, and a display screen and a sound and light alarm to prompt security personnel to capture videos for timely intervention and afterward detection; meanwhile, failing cameras can be locked to avoid system resource waste.

Description

technical field [0001] The invention relates to the field of intelligent video security monitoring systems, in particular to a linkage method of video acquisition equipment of a gunball machine by performing video analysis on a camera. Background technique [0002] The cameras used in the video security monitoring system are mainly divided into two categories: fixed-angle gun camera and dome camera. The dome camera has a rotatable pan / tilt, which can rotate in a wide range, change the focal length, and set a certain number of cameras. Each preset point is equivalent to a trigger with various indicators adjusted at this position, and it walks around multiple preset points in turn to realize the cruise scanning function. For this reason, the price of the dome camera is similar to The trigger of the indicator is several times higher. [0003] The security monitoring system usually sets gates at the entrance, cash registers, walls, etc. as the targets that must be monitored, an...
