Vehicle driving state detection method and device, electronic equipment and storage medium

Abstract

The invention discloses a vehicle driving state detection method. The method comprises the steps: obtaining a monitoring video stream, carrying out vehicle detection on the monitoring video stream, and obtaining a target detection frame of a current vehicle in a plurality of monitoring images in the monitoring video stream; determining a vehicle movement track vector according to the target detection frame positions of the Nth frame of monitoring image and the Mth frame of monitoring image in the monitoring video stream, wherein N is smaller than M, and the difference between M and N is largerthan a preset value; calculating a vector included angle between the vehicle movement track vector and a preset traffic flow direction vector; and if the vector included angle is greater than a preset included angle, judging that the current driving state of the vehicle is reverse driving. According to the invention, the detection accuracy of the vehicle driving state can be improved. The invention further discloses a vehicle driving state detection device, electronic equipment and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a vehicle driving state detection method and device, an electronic device and a storage medium. Background technique [0002] With the rapid development of society, road traffic pressure has also increased greatly, and traffic problems have become increasingly serious. Among them, behaviors such as driving in the opposite direction, reversing, and slipping can easily lead to danger, hinder the normal driving of other vehicles on the road, and endanger the order of road traffic. [0003] With the rapid development of intelligent transportation technology, the scale of road monitoring data has increased, making it more difficult for staff to distinguish and analyze. In addition, in the current video surveillance field, the detection of reversing vehicles has not yet been perfected. However, at present, reversing and retrograde behaviors frequently occur at r...

AI Technical Summary

Problems solved by technology

However, at present, reversing and retrograde behaviors at ramp intersections occur frequently, which can easily lead to traffic accidents, traffic jams, and other situations that disrupt road traffic conditions.

At present, in the reversing detection method, hardware devices such as ground sensing coils and monitoring devices are mostly used, or optical flow methods are used to obtain target movement trajectories. However, the above detection methods are easily affected by hardware and the environment. lower
