The Technology Research on License Plate Location and Character Segmentation

License plate identification technology is an important link of license plate recognition system, the pretreatment result will affect the subsequent effect of license plate recognition. This article research license plate location and character segmentation technology, proposing an improved Otsu algorithm and projection method to binary processing and location of the license plate, improve the accuracy of the threshold and location accuracy. Based on template method to segment the characters of license plate, horizontal scanning the characters after vertical segmentation of the license plate, finally realize the horizontal partition and vertical division. They all get good effects.
