摘    要:本文介绍数字图像处理在指针式指示表读数识别中的应用。计算机在获取指示表数字图像后,首先对图像进行预处理,然后通过Hough变换准确、快速地识别出指示表指针所在直线的位置,最后,利用指针位置和指示表读数的对应关系得到指示表的读数。

关 键 词:数字图像处理  读数识别  Hough变换  指针式指示表

Abstract:Application of Digital Image Processing in the recognition of indicator's reading is introduced. .After obtaining the digital image of indicator, the computer first preprocesses it ,then recognizes the position of the pointer accurately and quickly by Hough transform, finally gets the reading according to the relation between the reading and the position of pointer.
Keywords:Digital Image Processing  Hough transform  Recognition of  Reading
