Embodiment Construction

[0057] In order to better understand the technical content of the present invention, specific examples are given as follows.

[0058] Such as figure 1 Shown, according to a preferred embodiment of the present invention, a kind of method for the intersection pedestrian and motor vehicle collision prediction based on video detection, its realization comprises the following steps:

[0059] Step 1. Based on the predetermined intersection, the video capture device is used to capture and detect the movement information of motor vehicles and pedestrians in all situations of the predetermined intersection: the speed information and acceleration information of motor vehicles and pedestrians passing through the predetermined intersection at each moment in all cases And travel trajectory information, wherein the video capture device is located above the predetermined intersection:

[0060] Step 1.1, the video information captured by the video acquisition device is processed in frames to...

Abstract

The invention discloses an intersection pedestrian and motor vehicle collision prediction method based on video detection. The track information and the speed information of the motor vehicles and thepedestrians at the intersection can be rapidly extracted through combination of the image processing technology, and the probability of motor vehicle and pedestrian collision can be predicted by establishing an appropriate probability model so as to provide the appropriate data support for intersection safety assessment.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a method for predicting collisions between pedestrians and motor vehicles at intersections based on video detection. Background technique [0002] Urban intersection is an important connection point of urban roads. People, vehicles, roads, and environment at intersections are often more complex and changeable than ordinary road sections, and are frequent places of traffic accidents. Relevant data show that about 40% and 70% of traffic accidents in the United States and Germany occur at urban intersections each year. In Japan, fatal accidents at intersections account for about 40% of the total fatal accidents. At the intersection, there is a serious phenomenon of mixed traffic. Due to the different characteristics of various motor vehicle traffic flow and non-motor vehicle traffic flow, it not only affects the operation efficiency of the intersection, but also ea...
