Vehicle recognition method and apparatus, inspection system, storage medium, and electronic equipment

Abstract

The disclosure discloses a vehicle recognition method and apparatus, a vehicle inspection system, a storage medium, and electronic equipment, and is applied to the technical fields of vehicle recognition and vehicle safety inspection. The vehicle recognition method comprises: shooting a to-be-recognized vehicle by employing a linear array camera to obtain a plurality of linear array images of theto-be-recognized vehicle; performing distortion correction on the plurality of linear array images based on the moving speed of the to-be-recognized vehicle to obtain a plurality of corrected images;combining the plurality of corrected images to obtain a vehicle body image of the to-be-recognized vehicle; recognizing the type of the to-be-recognized vehicle in the vehicle body image based on a first pattern recognition algorithm; and recognizing the vehicle number of the to-be-recognized vehicle in the vehicle body image based on a second pattern recognition algorithm. According to the vehicle recognition method and apparatus, the vehicle inspection system, the storage medium, and the electronic equipment, the type and the vehicle number of the vehicle can be simultaneously recognized, the influence of the moving speed of the to-be-recognized vehicle on the image can be eliminated, the deformation of each linear array image is reduced, and the recognition accuracy of the type and thevehicle number can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle identification and vehicle safety inspection, and in particular, to a vehicle identification method and device, a vehicle inspection system, a storage medium, and electronic equipment. Background technique [0002] After entering the 21st century, China's national economy has entered a period of rapid development. With the continuous improvement of people's living standards, the total number of automobiles has also begun to increase rapidly. People's requirements for vehicle management are also getting higher and higher. The vehicle entrances and exits of various parking lots, highway toll stations, government agencies, and residential areas need to identify vehicles according to specific needs. [0003] For example, in the field of vehicle safety inspection, it is necessary to inspect container trucks and various trucks without stopping, and automatically identify the vehicle number on t...

Problems solved by technology

[0005] In the above method, the image information obtained through the light curtain is less, and the model and number of the vehicle cannot be recognized at the same time, and the installation is complicated; the cost of obtaining images through the area laser scanner is high and is easily affected by the environment; through the area array When the camera acquires the car body image, it is greatly affected by the speed of the vehicle, and the recognition accuracy is low
