Embodiment Construction

[0028] Combine below figure 1 and figure 2 , the present invention is further described:

[0029] figure 1 First, the detection system collects video images of highways according to the set step length through video equipment, and transmits the video signal to the video event detector; secondly, the video event detector outputs road traffic events (including parking, queuing, speeding) through three-step processing , retrograde, etc.) and traffic parameters (including flow, vehicle speed, vehicle type classification, etc.); finally, in order to make the types of detection events wider and the accuracy higher, the system uses a method that combines vehicle tracking detection and event algorithm detection. Vehicle tracking detection analyzes and processes expressway events through road traffic events output by event detectors, and event algorithm detection analyzes and processes expressway events through road traffic parameters output by event detectors. The two are compared...

Abstract

The invention relates to a traffic incident video detection method for a highway. The method comprises the following steps of: 1, acquiring highway video images according to a set step length through video acquisition equipment by using a detection system, and transmitting video signals to a video incident detector; 2, outputting road traffic incidents (comprising parking, queuing, speeding, running in the wrong direction, and the like) and traffic parameters (comprising traffic flow, vehicle speed, vehicle types and the like) by performing processing in three steps by using the video incident detector; and 3, analytically processing the incidents, namely performing incident analytical processing in a way of combining vehicle tracking detection and incident algorithm detection by using the detection system, wherein the vehicle tracking detection is used for analytically processing highway incidents by the road traffic incidents output by the incident detector, the incident algorithm detection is used for analytically processing the highway incidents by the road traffic parameters output by the incident detector, and an accurate detection effect can be achieved by the comprehensive comparison of the vehicle tracking detection and the incident algorithm detection.

Description

technical field [0001] The invention relates to a video detection method for highway traffic incidents, in particular to a video detection method for highway traffic incidents based on a combination method of vehicle tracking detection and event algorithm detection. Background technique [0002] Traffic incidents refer to frequent parking incidents, retrograde incidents, pedestrian incidents, throwing incidents, smog incidents, congestion incidents and other special incidents that interrupt normal traffic, cause congestion and delays, and reduce road traffic capacity. The loss of productivity, property damage, and personal injury caused by traffic accidents all over the world reaches hundreds of millions of dollars every year. Due to the frequent occurrence of traffic accidents, it has become a serious social problem in our country. [0003] Video traffic incident detection technologies are generally divided into two categories: "indirect detection methods" and "direct dete...
