Abstract

The invention relates to the technical field of image processing, and provides a vehicle brand recognition method and a device, and a readable storage medium, and the method comprises the steps: firstly obtaining a vehicle image, inputting the vehicle image into a preset convolutional neural network, and carrying out the feature extraction through a first network, and obtaining a first feature map; performing region detection on the first feature map to obtain a first vehicle feature region, and performing secondary feature extraction on the first feature map by using a second network to obtain a second feature map; and finally, extracting a plurality of vehicle brand features in the second feature map according to the first vehicle feature region, and identifying a vehicle brand in the vehicle picture according to the plurality of vehicle brand features. Compared with the prior art, the vehicle brand identification efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, in particular, to a vehicle brand recognition method, device and readable storage medium. Background technique [0002] With the advancement of science and technology, the intelligent transportation system has developed rapidly. More and more vehicles have caused road congestion and frequent accidents. Therefore, stricter management of the transportation system is required. Vehicle brand recognition is an important part of extracting the structured information of the entire vehicle. In order to achieve stricter traffic management, it is necessary to identify the vehicle brand. [0003] In the prior art, brand recognition is performed based on the precise location information of the license plate. When the vehicle has no license plate, the license plate cannot be located, and the license plate location is inaccurate, etc., the efficiency of vehicle brand recognition...
