摘要
介绍了一种基于LabVIEW的数字识别原理。对一幅BMP图片进行二值化、清除杂质 ,以及图片分割等处理 ,得到每个数字的黑白图片。再通过提取如 :列交点数、环状结构的数目、环的位置以及弯钩结构的数目、位置等特征信息 ,区分 0～9这 1 0个数字。本程序对图片的拍摄效果要求不高 。
This article introduces a method of numeral recognition based on LabVIEW The program reads a BMP file and transfers it into a black\|white image through partition,impurity deleting,image dividing, then identifies 0～9 through getting the character information such as column cross, the number of circle structure,the location of circle,the number of hook structure and the location of hook This program does not ask for high requirement on the effect of picture and can be used in digital meter
