Problems solved by technology

However, intelligent image analysis has not yet been formally applied in domestic rail transit projects. The location, quantity, and analysis mode are different from the conventional ones due to the influence of the overly dense passenger flow factors on the site. The foreign application mode cannot be directly applied to domestic In the subway industry, a large number of statistics, analysis and comparative studies are required to obtain a system solution with reasonable investment and significant effect

Abstract

The invention relates to a monitoring device, in particular to an intelligent analysis method for video monitoring images in rail transit. In the method, a camera is used for collecting the image information of a monitoring area in the rail transit, and the image information is transmitted to a monitor so as to monitor the rail transit. The method is characterized by comprising the following steps of: transmitting the image information in a digital mode to a video analysis server through a switch after the camera collects the image information; comparing and analyzing the image signal and a preset alert threshold by a video analysis module in the video analysis server; transmitting the image information triggering the alert threshold as selected image information to a video control server through the switch; and finally, controlling the selected image signal by the video control server to output the selected image signal to the monitor to be displayed. The invention has the advantages of reducing the working strength of manual monitoring and improving working efficiency and monitoring effect.

Description

technical field [0001] The invention relates to monitoring devices, in particular to an intelligent analysis method for video monitoring images used in rail transit. Background technique [0002] With the continuous popularization of rail transit in cities, the scale of video surveillance systems in subways, stations and station intervals is becoming larger and larger, the number of cameras is increasing, and the content of video surveillance in rail transit is also increasing. If traditional video surveillance methods are used , you need to increase a large number of monitors and call a large amount of manpower to effectively monitor rail traffic. [0003] Therefore, it is imperative to adopt intelligent image analysis technology in rail transit, and intelligent image analysis technology has been applied in subway abroad. However, intelligent image analysis has not yet been officially applied in domestic rail transit projects. The location, quantity, and analysis mode are ...
