Digital video surveillance method, digital video surveillance system and digital video surveillance platform for moving object

Abstract

The embodiment of the invention discloses a digital video surveillance method, a digital video surveillance system and a digital video surveillance platform for a moving object, wherein the method comprises the steps as follows: a video surveillance client side detects coordinates (x1, y1) of the moving object that is clicked on a monitoring picture of a main video camera by a user, and sends thecoordinates to the digital video surveillance platform; the digital video surveillance platform calculates coordinates difference value (x, y) between the coordinates (x1, y1) of the moving object and center coordinates (x2, y2) of the monitoring picture, wherein, x equals to x2 minus x1, and y equals to y2 minus y1; and the digital video surveillance platform controls a tripod head to rotate according to the coordinates difference value (x, y), so as to lead the moving object to be positioned in the center range of the monitoring picture. The embodiment of the invention can effectively trackthe moving object, and can achieve the video surveillance on the moving object.

Description

technical field [0001] The invention relates to video monitoring technology, in particular to a digital video monitoring method and system for a moving target, and a digital video monitoring platform. Background technique [0002] At present, many information technology companies have gradually entered the field of security services, and thus have improved the level of science and technology in the field of security services. With the advancement of technology, security monitoring technology has also made great progress. So far, the development of video surveillance technology for security monitoring services has gone through the analog age and the digital age. With the construction of large-scale projects such as the Shanghai World Expo in China and the National Safe City and grid management, security work has become a continuous hot spot in recent years. As the most direct means of security work, video surveillance services have been widely used. [0003] Video surveill...

Problems solved by technology

In the digital video monitoring system, it takes a certain amount of time for the image to be transmitted from the camera on the PTZ to the client of the monitoring screen, and it also takes a certain amount of time for the PTZ command to be transmitted from the client to the PTZ through the network, resulting in slow response of the PTZ. The control of the pan / tilt is inflexible, the camera cannot track fast-moving targets, or the moving target is out of the range of the monitoring screen due to the excessive rotation of the pan / tilt, so it cannot effectively track the moving target, which greatly limits the development of digital video surveillance services, such as , which limits the monitoring application of digital video surveillance system in key parts of "Safe City"
