The invention mainly relates to a visual detection method, in particular to a motor vehicle registration certificate detection method based on vision. The method includes the following steps of 1, image acquisition, wherein a motor vehicle registration certificate image containing the information of a number plate, an engine code, a vehicle identification number (VIN), the registration date, the issue date and a red seal is acquired; 2, information localization, wherein the five pieces of information of the number plate, the engine code, the VIN, the registration date and the issue date on the motor vehicle driving license are localized through image processing; 3, character segmentation, wherein character segmentation is carried out on the number plate, the engine code, the VIN, the registration date and the issue date which are localized in the step 2, and single character segments obtained through segmentation are stored in a classified mode; 4, character recognition, wherein through a trained artificial neural network classifier, single character recognition is carried out on the single character segments obtained through segmentation in the step 3, and the recognition result is output. The method is used for registration certificate information recognition.
