Abstract

The invention provides a tunnel accident automatic detection method, which is mainly characterized by comprising the following steps: first, collecting video data of a monitoring area and carrying outpretreatment; 2, background pixel are separated from that original image by use a mixed Gaussian model for background modeling; 3, extracting a moving object from the surveillance video image; 4, recording the trajectory information of the moving object so as to recognize the information of the move object and marking the moving object; 5, tracking the marked moving object in the tunnel; 6, whenthe trajectory of the move target exceeds the set threshold, an alarm message is sent out. The tunnel accident automatic detection method provided by the invention can detect and track the moving objects such as vehicles in the tunnel omni-directionally, accurately and efficiently through the real-time monitoring of the tunnel, and can be applied to complex scenes with high detection accuracy andgood real-time performance, and has important application value.

Description

technical field [0001] The invention belongs to the technical field of security monitoring, in particular to a tunnel accident automatic detection method. Background technique [0002] The video surveillance system is the technical means that the tunnel operation and management system at home and abroad mainly relies on. At present, most of the operational security incidents are mainly based on manual observation of video surveillance images, and 90% or more of the video surveillance images cannot be focused on. It was found that operational security incidents are the main bottleneck of the existing video surveillance system. In order to solve the outstanding problems of tunnel operation safety management, improve tunnel safety operation efficiency, and ensure driving safety, it is necessary to provide an automatic detection method for tunnel operation safety events based on video recognition. Contents of the invention [0003] In view of this, the tunnel accident automat...
