Vehicle brand identification method, device and equipment and storage medium

Abstract

The invention discloses a vehicle brand recognition method, device and equipment and a storage medium, and the method comprises the steps: carrying out the secondary training of a recurrent attentionconvolution neural network based on a first loss function and a second loss function according to a rear-photographed vehicle window face image sample, and obtaining a vehicle brand recognition model,wherein each classification sub-network in the recurrent attention convolutional neural network takes a resnet network as a convolutional layer, and each classification sub-network in the vehicle brand identification model takes a second loss function as a loss function; preprocessing the received vehicle initial image to obtain a post-shot vehicle image; performing vehicle window face detectionon the back-shot vehicle image to obtain a vehicle window face area image in the back-shot vehicle image; obtaining a vehicle brand identification result of the vehicle window face area image througha vehicle brand identification model according to the vehicle window face area image. According to the method, the problems of unbalanced vehicle logo sample data distribution and complex and variablevehicle angles can be effectively solved, and the vehicle logo identification accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a vehicle brand recognition method, device, equipment and storage medium. Background technique [0002] The vehicle identification system is an important part of the intelligent transportation system, and the identification of vehicle brand styles can effectively assist in vehicle retrieval and comparison, which in turn helps to detect vehicle violations. Therefore, the research on the vehicle brand style recognition method in the traffic monitoring scene has a wide range of application value. [0003] Vehicle brand identification, also known as vehicle manufacturer identification, mainly determines the vehicle brand by locating the vehicle logo and the type of the vehicle logo. However, because the vehicle logo recognition method has a high dependence on the positioning of the vehicle logo, the quality of the positioning directly affects the final recogniti...
