介绍了一种数字仪器七段码显示图像识别方法,是在VC+ +环境下编程实现的.根据七段码图像的特征,提出了合适的分段线性灰度变换法、倾斜度调整法、特征提取法.实验表明这种识别方法识别率高,识别速度快.

This paper gives an introduction about a seven - segment display recognition method for use with digital instruments. This method is implemented in the VC ＋ ＋ 6. 0 programming environment. According to the feature of a seven - segment image, the paper presents an appropriate piecewise linear gray level transformation method, slop angle adjustment method and feature extraction method. The experimental results show that the recogniti...
