Video monitoring system and video monitoring method

Abstract

The invention discloses a video monitoring system and a video monitoring method. Direction of a pan-and-tilt camera is adjusted according to received pan-and-tilt control commands, and the pan-and-tilt camera acquires front-end videos and outputs the same to a pan-and-tilt camera path. A monitoring platform feeds the pan-and-tilt camera path back to a client side and tracks a policy list automatically after performing access authentication on the client side, and outputs received pan-and-tilt control commands to the pan-and-tilt camera after performing control authentication on the received pan-and-tilt control commands. The client side selects an automatic tracking policy from the automatic tracking policy list, packages presetting-bit commands in the pan-and-tilt control commands and outputs the pan-and-tilt control commands to the pan-and-tilt camera; and according to the acquired pan-and-tilt camera path, real-time videos are downloaded to play, and according to the played videos, a target object is positioned, and the position of the target object at the next calculating time is predicted and packaged in the pan-and-tilt control commands to transmit. By the video monitoring method, tracking efficiency can be improved while monitoring cost is reduced.

Description

technical field [0001] The invention relates to video monitoring technology, in particular to a video monitoring system and a video monitoring method. Background technique [0002] The video surveillance system is an important part of the security system widely used in various industries, and it is also an important part of the intelligent transportation system. With the rapid development of computer, network transmission technology and image processing technology, the field of video surveillance is undergoing a revolution, and it is developing from traditional analog video system to digital video system. With its great flexibility, the digital video surveillance system can not only effectively monitor the scene and record evidence, but also analyze and track the target with the help of video analysis technology. The advantages brought about by digitization will completely change the pattern of the video surveillance field, and the digital video system based on IP network i...

Problems solved by technology

However, in the digital video surveillance system, there is a certain delay when the control command output from the pan / tilt controller is transmitted to the single camera. When the single camera receives the control command for tracking, the actual vehicle has deviated, making the tracking accuracy of the single camera Furthermore, because the vehicle has the characteristics of fast running speed and high density, it is difficult for the user to control the operation, and it is easy for a single camera to fail to locate the target vehicle, or locate the wrong target vehicle, or because the focal length is not adjusted in time, the positioning The size of the target vehicle is not enough to obtain effective information, which weakens the effect of video surveillance in the field of transportation

[0004] In order to avoid the above-mentioned defects in the tracking of digital video surveillance systems, the prior art proposes an intelligent high-speed tracking dome machine, that is, an intelligent high-speed tracking dome machine is used to track the target object, which can effectively track and locate the vehicle. In the transformation of a digital video surveillance system, the existing single camera needs to be replaced, which makes the operating cost of the system high, and is generally only used in new projects; moreover, even if it is applied to new projects, the monitoring cost is high due to its complex structure; Moreover, the application of intelligent high-speed tracking dome cameras in intelligent transportation does not have the function of saving video and capturing vehicle pictures during the tracking process. It requires a large number of monitoring personnel to perform operations such as video recording and capturing, which makes more manpower investment. Limited, high monitoring cost
