Abstract

The present invention provides a body color recognition method and device, the method comprising: determining the body color recognition area in the front face area of ​​a target vehicle; determining the multi-dimensional color histogram features of the body color recognition area; The histogram features are input into the pre-trained neural network, and the vehicle body color is determined according to the output result of the neural network. The application of the embodiments of the present invention can improve the accuracy of vehicle body color recognition and reduce the performance loss of vehicle body color recognition.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a vehicle body color recognition method and device. Background technique [0002] Intelligent Transportation System (Intelligent Transportation System, referred to as ITS) is a management system currently being used in many cities. It involves a wide range of fields, mainly including multiple modules such as road condition collection, vehicle identification, violation processing, and self-service payment. Digital technology realizes information exchange among various modules, thereby promoting the effective use and management of urban roads, and achieving the purpose of alleviating traffic congestion. [0003] However, with the continuous growth of the number of vehicles and traffic volume, illegal and criminal acts that hinder traffic order, such as car decks, multiple licenses for one vehicle, and multiple vehicles for one license, have become particularly prom...
