Abstract

The invention discloses a vehicle logo recognition method and system based on a selective search algorithm. The vehicle logo recognition method based on a selective search algorithm includes the steps: performing positioning of a license plate on an original vehicle image, and acquiring the position of the license plate; according to the position of the license plate, the spatial position relationship between the license plate and an vehicle logo, and the vehicle window edge information, performing coarse positioning on the vehicle logo in the original vehicle image, and obtaining an vehicle logo coarse positioning image; based on a central axis of the vehicle, selecting a vehicle logo candidate area in the vehicle logo in the original vehicle image; using a selective search algorithm to perform target positioning on the vehicle logo candidate area, and obtaining a positioning target set; utilizing a linear constraint coding algorithm to train a vehicle logo determination classifier to perform determination on the vehicle logo for the positioning target set to obtain the position of the vehicle logo; and utilizing the linear constraint coding algorithm to train a multi-type vehicle logo recognition classifier to perform concrete type recognition on the vehicle logo, and obtaining the vehicle logo recognition result. The vehicle logo recognition method and system based on a selective search algorithm have the advantages of extensive applicability, high robustness and high detection speed, and can be widely applied to the image processing field.

Description

technical field

[0001] The invention relates to the field of image processing, in particular to a vehicle logo detection and recognition method and system based on a selective search algorithm. Background technique

[0002] The vehicle logo detection system is an important part of the intelligent transportation system. As a unique symbol of the vehicle brand, the correct identification of the vehicle logo can effectively assist the vehicle identification system to match the relevant information of the vehicle, which will benefit the vehicle. The determination of identity improves the recognition rate of vehicle models. Vehicle logo recognition has a wide range of applications in the field of intelligent transportation, such as vehicle model matching, vehicle information collection, and fake license plate detection. In reality, the area, shape, and texture of car logos are different, and the background grids of car logos are also diverse. At the same time, the differences in...
