Abstract

The present invention mainly relates to a visual detection method, more specifically, to a visual detection method for a motor vehicle license, comprising the following steps: (1), image collection: collecting a number plate containing a number plate, an engine code, and a vehicle identification number VIN, date of registration, date of issuance and the image of the motor vehicle license of red seal information; (2), information positioning: use image processing to analyze the number plate, engine code, vehicle identification number VIN, registration date on the motor vehicle license (3), character segmentation: perform character segmentation on the number plate, engine code, vehicle identification number VIN, registration date and certificate issuance date located in step (2) Good single-character block classification storage; (4), character recognition: carry out single-character recognition with the trained artificial neural network classifier to the single-character block obtained by step (3), and output the recognition result. This method is used for identification of driving license information.

Description

technical field [0001] The present invention mainly relates to a visual inspection method, and more specifically, relates to a visual inspection method for a motor vehicle driving license.
