Problems solved by technology
At present, most of the operational security incidents are mainly based on manual observation of video surveillance images, of which 90% and above video surveillance images cannot be focused on, and operational security incidents cannot be found in the first place. This is the main bottleneck of the existing video surveillance system, and the event Very low coverage was found

The invention relates to a video-identification-based highway running safety incident automatic-detection system, which comprises a data acquisition module, a characteristic preprocessing module, a safety incident detection module and a monitoring center, wherein the data acquisition module is used for acquiring traffic parameter data on a highway; the characteristic preprocessing module is used for preprocessing the acquired traffic parameter data; the safety incident detection module is used for performing safety incident detection and assessment on the preprocessed traffic parameter data and meteorological environment data, and transmitting an assessed safety incident level to the monitoring center; the monitoring center is used for outputting a corresponding incident alarming level. The video-identification-based highway running safety incident automatic-detection system is established, and a relative detection and direct detection fusion method is adopted, so that the system is high in automatic detection rate and low in false alarm rate, and has high popularization value.
Description
technical field [0001] The invention relates to a detection system, in particular to an automatic detection system for expressway operation safety incidents based on video recognition. Background technique [0002] The video monitoring system is the technical means mainly relied on in the operation and management system of expressways at home and abroad. At present, most of the operational security incidents are mainly based on manual observation of video surveillance images, of which 90% and above video surveillance images cannot be focused on, and operational security incidents cannot be found in the first place. This is the main bottleneck of the existing video surveillance system, and the event The coverage was found to be extremely low. In order to solve the outstanding problems of expressway operation safety management, improve the efficiency of expressway safety operation in the city, and ensure driving safety, it is necessary to establish an automatic detection syst...
