Abstract

The invention relates to the field of information identification, in particular to a vehicle driving license picture self-adaptive correction and identification method. According to the invention, thedriving license is photographed, the red seal is positioned by using the deep neural network for the photographed picture, the front page of the driving license is corrected and extracted based on the position state of the red seal, the front page of the driving license is processed by using multiple custom algorithms based on Hough transform, and the driving license information is identified byusing the Tesseract-OCR engine. According to the method, manpower is saved, the information of the driving license can be quickly and accurately identified automatically by utilizing a computer, the influence of noise, unclear pictures, large color difference of a shooting camera, black and vertically-arranged anti-counterfeiting lines on the front page of the driving license and colors on information identification can be eliminated, the shooting background of the driving license does not need to be considered, and the invention has excellent accuracy and high robustness.
