Abstract

The embodiment of the invention provides a vehicle detection device and method and an electronic device. By detecting a color image directly, and through two times of different pairing processing, theheadlight and the taillight of a vehicle can be detected and paired at the same time, and the influence of the steering lights of the vehicle on the detection result can be avoided, so that the possibility of missed detection and false detection is reduced to a great extent, and the comprehensiveness and accuracy of the vehicle detection result are effectively improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a vehicle detection device and method, and electronic equipment. Background technique [0002] With the complexity of urban traffic conditions, the demand for monitoring and controlling traffic conditions is becoming more and more common. The detection of moving vehicles is one of the common functions of video surveillance. Current vehicle detection methods generally aim at scenes with better light, such as daytime, and use classifiers to detect and count vehicles in surveillance images. For scenes with poor light, such as at night, it is difficult for general vehicle detection methods to detect vehicles effectively. [0003] The existing general process of vehicle detection for scenes with poor light is: obtain a binary image according to the grayscale image of the surveillance video image, and extract the highlighted areas, and then pair each highlighted area, according ...
