Embodiment

[0040] Such as figure 1 As shown, the traffic monitoring video recognition accident detection method for vehicle collision disclosed in the present invention provides two detection algorithms under the same design principle, which will be described separately below.

[0041] Algorithm one

[0042] 1. Determine the stopping behavior within the zone target.

[0043] (1) According to the video sequence, the background image is generated by using the mixed Gaussian background modeling method, and then the foreground image is obtained by the method of front and background difference;

[0044] (2) Accumulate the foreground image until there is a target suspected block that stops the behavior, and judge whether the size of the target suspected block exceeds the preset threshold;

[0045] (3) If the target suspected block exceeds the preset threshold, it is determined to be a stop behavior.

[0046] 2. Use the frame interval to calculate the direction and magnitude of the histori...

Abstract

The invention discloses an accident detection method for recognizing a vehicle collision through a traffic monitoring video. The method includes the steps that 1, a stop behavior in an area target is determined; 2, the direction and amplitude of a surrounding historical light stream of the stop behavior are calculated according to an inter-frame space, and whether a light stream collision point exists around the stop behavior is judged; if yes, it is determined that the collision accident happens, the accident is reported, and judgment is finished; otherwise, the step 3 is executed; 3, the inter-frame space is changed, the direction and amplitude of the surrounding historical light stream of the stop behavior are recalculated, and whether a light stream collision point exists around the stop behavior is judged; if yes, it is determined that the collision accident happens, the accident is reported, and judgment is finished; otherwise, the step 3 is repeatedly executed till the inter-frame space exceeds 5, and it is determined that no collision accident happens currently if no light stream collision point is found around the stop behavior. The method is simple in principle and convenient to implement and has great practical value.

Description

technical field [0001] The invention relates to a traffic accident detection method, in particular to an accident detection method for traffic monitoring video recognition vehicle collision. Background technique [0002] With the rapid increase of the number of urban vehicles, the traffic pressure is also becoming greater and greater, and the way of monitoring urban traffic conditions by video has become more and more common. However, due to the large number of monitoring probes, relying on manual management of monitoring probes can no longer meet the actual requirements. It is imminent to replace the traditional manual supervision with high-efficiency and intelligent technological means. [0003] For urban traffic, the two important causes of traffic paralysis are congestion and accidents. If the accident is not handled in time after the accident, it will directly cause traffic congestion. At present, the main means of discovering traffic accidents are the following three...
