Method and system for vehicle logo recognition

Abstract

The embodiments of the present invention provide a vehicle logo recognition method and system. Each type of vehicle logo recognition model is projected to an optimal identification vector space through linear discriminant analysis (LDA) to obtain a model feature vector, wherein the method includes: obtaining a vehicle logo area By LDA projection to described best identification vector space by described car logo area, obtain car logo feature vector; Calculate the Euclidean distance between described car logo feature vector and all model feature vectors, choose a predetermined one and described car logo feature The model feature vector with the closest vector Euclidean distance; the car logo area is identified by using the car logo recognition models corresponding to all the selected model feature vectors, and the car logo recognition result is obtained. Improve the recognition speed of car logo.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a vehicle logo recognition method and system. Background technique [0002] At present, the license plate recognition equipment has been widely used at the entrance and exit of the parking lot to manage the vehicles entering and leaving the venue. The current license plate recognition system uses the mode of entering and taking cards, one car and one card for license plate recognition. However, because the license plate recognition rate of the license plate recognition equipment is generally only about 95%, it is impossible to guarantee that all the captured license plates can be fully recognized. Therefore, staff are generally deployed at the entrance and exit of the parking lot to assist in the license plate equipment. However, in recent years, with the increase of labor costs, unattended parking lots have begun to be promoted. License plate recognition is still the only standar...

Problems solved by technology

[0003] In view of this, the embodiment of the present invention provides a vehicle logo recognition method and system to solve the problem that the recognition speed of the car logo is slow in the prior art, so that the recognition of the car logo loses its due timeliness, making it impossible to recognize the car logo. At the entrance and exit of the parking lot, etc. to assist in the management of vehicles entering and leaving the venue, the problem of losing the meaning of car logo recognition
