Study on license plate recognition based on HALCON
摘要
Abstract
In order to achieve accurate and quick recognition of license plates,a license plate positioning method with secondary threshold is proposed based on Halcon. A primary threshold is made based on the license plate texture characteristics of S channel in HSV color mode to get the candidate region of a license plate,and then adjusting the candidate region to make the second threshold and determine the exact license plate region according to the maximum(minimum)row(column)value of the character region. As for the character segmentation module,a method to combine Chinese character segmentation with other character connected domain method is proposed. The experimental results indicate that both of the two methods are simple and quick,and have high recognition rate.关键词
