摘　　要：介绍了一种基于VC++的医用电子体温计的自动识别方法。根据电子体温计显示的特点,提出了一种利用机器视觉识别电子体温计读数的一种新方法。该方法利用扫描法进行字符区域的定位和单个字符的分割;利用穿线法识别数字字符;利用穿线法和模板匹配相结合的方法识别小数点。实验结果表明,该算法识别率高,识别速度快。An automatic recognition method on an electronic thermometer display is introduced. It is implemented in the VC ＋ ＋ 6.0 programming environment. According to the feature of electronic thermometer display, a new method for recognizing the electronic thermometer display with machine vision is presented. The new method uses scanning method to locate the display area of electronic thermometer and segment the characters. The numeric characters are recognized by threading method, and the decimal point character is recognized by taking advantage of threading method and template matching method. The experimental results show that the the new algorithm of the recognition method can raise its efficiency and accuracy.
