Abstract

The invention relates to the field of image detection, and particularly discloses a vehicle overspeed monitoring method and device, computer equipment and a storage medium, and the method comprises the steps: extracting a first frame of image and a second frame of image in a video stream of vehicle driving, and extracting a plurality of first vehicle pixel point coordinates in the first frame of image, calculating a distance value between each first vehicle pixel point coordinate and each second vehicle pixel point coordinate according to a plurality of first vehicle pixel point coordinates in the first frame image and a plurality of second vehicle pixel point coordinates in the second frame image, and constructing a distance matrix, determining a first pixel point coordinate of the target vehicle in the first frame image and a second pixel point coordinate of the target vehicle in the second frame image according to the distance matrix, and calculating an actual moving distance of the target vehicle according to the first pixel point coordinate and the second pixel point coordinate; and further calculating the current vehicle speed of the target vehicle. The overspeed monitoring of the vehicle can be realized by using the existing traffic monitoring camera device without adding extra distance measuring equipment, the cost is low, and the reliability is high.

Description

technical field [0001] The invention relates to the field of image detection, in particular to a vehicle overspeed monitoring method, device, computer equipment and storage medium. Background technique [0002] Speeding is one of the main factors causing traffic accidents. Therefore, real-time monitoring of vehicle speed is of great significance to reduce traffic accidents. [0003] At present, the most widely used vehicle speed detection technologies in China mainly include radar speed measurement, laser speed measurement and infrared speed measurement. Although these speed measurement technologies have high measurement accuracy, the speed measurement equipment is expensive and difficult to popularize in large numbers. [0004] Therefore, it is particularly important to find a safe, reliable, and economical speed measurement method. Contents of the invention [0005] Based on this, it is necessary to provide a safe, reliable and economical vehicle overspeed monitoring m...
