Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. The specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0059] Such as figure 1 Shown is an embodiment of the present invention, which specifically discloses a silent low-point video surveillance traffic jam event detection method, based on the detection and tracking results of road vehicle targets. It should be noted that in this embodiment, the road vehicle target The detection and tracking results can be detected based on the existing vehicle target detection and tracking technology. The purpose is to obtain the road ROI area that needs to be detected and tracked, and then agree on the road ROI area that needs to be detected and tracked in any frame of the video captured by the camera. The ROI area is represent...

Abstract

The invention belongs to the field of intelligent transportation, and specifically discloses a silent low-point video monitoring traffic congestion event detection method, which is suitable for the situation where the camera is erected at a height of 5-8 meters, based on the number of vehicles, the quietness ratio, the space occupancy rate and the target The four traffic parameters of coincidence rate are used to quantify and classify traffic conditions in a short period of time in real time, and perform statistical analysis on the classification results in the time domain to finally determine whether traffic jams occur. Automatic detection and identification of traffic jams can be achieved. Severity of congestion. The present invention can replace manual inspection, realize automatic inspection, find congestion events in time, and quickly remind, so that measures can be quickly taken to solve the problem of traffic congestion.

Description

technical field [0001] The invention relates to the field of detection of traffic congestion events, in particular to a method for detecting traffic congestion events of silent low-point video monitoring. Background technique [0002] With the rapid development of Chinese cities, more and more people are gathering in cities, and the urban population is growing rapidly. Due to the improvement of people's living standards and the rapid increase in the number of private cars, the urban traffic situation is getting worse and worse, and traffic congestion has become a persistent problem in urban traffic. This situation is more prominent in regional central cities. The hidden events behind the traffic congestion incidents, what causes the traffic congestion, how to solve the traffic congestion faster, and how to take effective measures to prevent traffic congestion are issues that must be paid attention to in urban development at present. [0003] There are many reasons for traf...
