摘　　要：对当前典型的车辆牌照字符识别算法进行了研究和分析,在此基础上提出一种新型算法,通过提取一些具有表征性的字符结构特征构建合理的判决树进行有效识别。采用车牌识别系统中分割出的一些数字和字母进行识别仿真,实验结果表明该算法简单、快速、高效,在复杂的噪声环境下同样具有较高的识别率。Based on the analysis and comparison of current popular vehicle plate character recognition methods, we propose a novel algorithm, which extracts some discriminative structure features of characters, and constructs a rational decision tree to perform effective recognition. The results of recognition simulation on numbers and characters extracted from vehicle plate recognition system prove that the algorithm is simple and efficient, and has high recognition rate even in noisy environment.
