License plate recognition technology process includes license plate location, character segmentation and character recognition. Firstly, according to the horizontal and vertical projection of the license plate, a rectangular region is found to locate the true position of the license plate, then the character binaries are transformed into recognizable black and white images, and the vehicle license plate numbers are segmented and normalized by character spacing. Finally, the characters are identified, and the extracted characters are inferior to the character template library which is set up in advance, and 0 means that the two are completely matched, saving each character that subtracts to 0, which is the license plate you asking for.
