Problems solved by technology

There is a certain error in character segmentation. If the segmentation is wrong, it will affect the subsequent recognition
For example, if "8" is cut to the right and lacks the details on the left, it will be easily recognized as "B"; The loss is serious, and the recognition rate of the car logo is low

Abstract

The invention discloses a vehicle identification recognition method and a system. According to the method, positive samples and negative samples of images of target vehicle identifications needing classification are acquired from monitoring videos of gateways of a parking lot, the vehicle identifications comprise license plate images or vehicle identification images, preset characteristics of all the samples are extracted, the extracted preset characteristics are classified into K classes through a K mean value clustering algorithm, the K classes of the preset characteristics are trained through a preset training method to acquire K model classifiers, the vehicle identifications are classified and recognized through the K model classifiers, the optimum classification of the license plates or the vehicle identifications can be realized after K mean value clustering, the preset characteristics after optimum classification are trained to acquire corresponding model classifiers, the vehicle identifications are classified and recognized commonly, the recognition rate of the license plates or the vehicle identifications can be improved, and vehicle recognition can be more accurately realized.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a vehicle identification method and system. Background technique [0002] License plate recognition equipment has been widely used in parking lot entrances and exits to manage vehicles entering and leaving the park. However, the recognition rate of license plate recognition equipment is still difficult to meet user needs, so parking lot entrances and exits are generally equipped with staff to assist users. With the increase in labor costs, unattended parking lots have begun to be popularized. [0003] License plate recognition generally includes license plate detection, license plate character segmentation and license plate character recognition. Vehicle logo recognition is a supplement to license plate recognition and is used to assist in identifying vehicles. At present, the mainstream technologies of license plate detection, license plate character recognition, and vehicle log...
