Embodiment

[0049] Such as Figure 1 to Figure 5 As shown, it is a real-time traffic video image of a road section in Xi'an. The sampling frequency of the video is 25 frames per second, the video image size is 720×288, and the size of each block is 8×6, so each frame of video image is divided into 90× There are 48 blocks, there are many vehicles on this road, the selected target segmentation threshold A is 500, the abnormal block detection threshold B is 120, the vehicle width threshold C is 8, and the number of frames m before the current frame is read is 200, that is, forward The number of frames to be tracked is 80 frames, and the number n of frames after reading the current frame is 50, that is, the number of video image frames to be tracked in the future is 50 frames. According to the above method, the above video image is processed.

[0050]It can be seen from the figure that after the suspicious area in the video image is detected, the video image is tracked, and the running track...

Abstract

The invention discloses a parking event detecting method based on a double tracking system. By means of segmentation of a plurality of block areas and drawing of a dynamic background, the sum of absolute values of pixel value differences of each area of the background corresponding to a current frame is calculated, the steps are repeated, a suspicious area is marked and assigned a value 255, a connected domain analysis is conducted, and whether a car is parked on the suspicious area is confirmed. The parking event detecting method based on the double tracking system is free from environmental constraints, a real-time detection can be conducted, the impacts of shadows, lights, threw objects and surface gathered water can be eliminated preferably by means of the combination of the analysis of tracing lines, the algorithm can achieve real-time and accurate detection of road unusual parking events, rescue and handling of a traffic accident can be conducted timely and effectively, a secondary accident is prevented from happening, and the safety of road operation is further guaranteed.

Description

technical field [0001] The invention belongs to the field of video detection, and in particular relates to a parking event detection method based on two-way tracking. Background technique [0002] In recent years, with the continuous increase of traffic volume, traffic accidents have become more and more frequent. Among many accidents, traffic accidents caused by illegal parking are particularly serious, because parking incidents are sporadic and random, and it is difficult to find them in time. And exclude, once an accident occurs, it will cause traffic jams, seriously affect the normal traffic capacity of the road, and easily cause subsequent accidents, resulting in very serious consequences. Therefore, it is particularly important to establish a parking detection system. [0003] At present, the automatic detection algorithms of traffic incidents can be generally divided into two categories: indirect detection methods and direct detection methods. The indirect detection...
