Vehicle identification method based on fusion of radar and vision information

Abstract

The invention discloses a vehicle identification method based on fusion of radar and vision information. The vehicle identification method based on fusion of radar and vision information includes thefollowing steps: S100, entering all the information of a vehicle to be identified; S200, acquiring the current positional information and the motion state information of the vehicle; S300, acquiring the appearance information of the vehicle to be identified; S400, comparing the acquired appearance information of the vehicle to be identified with the entered vehicle information; and S500, recordingand uploading the information of the illegal vehicle and the vehicle driver. The vehicle identification method based on fusion of radar and vision information monitors the vehicles on the road in real time through the method of integrating the radar with vision information, determines the best position of shooting through the radar, can capture the clear image of the vehicle to be identified, canobtain the information of the vehicle to be identified through vision information processing, can determine whether the driver has illegal behavior through information comparison, and can greatly improve the accuracy and efficiency of vehicle identification through the method of combining the radar and the vision information.

Description

technical field [0001] The invention relates to the field of traffic monitoring, in particular to a vehicle recognition method based on fusion of radar and visual information. Background technique [0002] The license plate recognition system refers to a technology that can detect vehicles on the monitored road and automatically extract vehicle license information (including Chinese characters, English letters, Arabic numerals and license plate colors) for processing. License plate recognition is one of the important components of modern intelligent transportation systems, and it is widely used. Based on digital image processing, pattern recognition, computer vision and other technologies, it analyzes the vehicle images or video sequences captured by the camera, and obtains the unique license plate number of each car, thus completing the recognition process. Through some follow-up processing methods, functions such as parking lot fee management, traffic flow control index m...

AI Technical Summary

Problems solved by technology

[0005] (1) The vehicle identification method in the prior art only photographs and captures traffic violations, but cannot capture illegal modifications such as vehicle appearance and license plate replacement, and there are certain potential safety hazards;

[0006] (2) In the vehicle recognition method in the prior art, in the process of capturing the exterior image of the vehicle to be recognized, due to the different angles of shooting the vehicle to be recognized, the completeness of the captured vehicle image to be recognized is different, resulting in the inaccuracy of the captured vehicle information to be recognized Integrity, causing the error of vehicle recognition to increase
