摘要
Abstract
Due to the problem of the analog meter signal can not be converted into digital signal input into computer,and the low efficiency of the human eye for the analog meter reading, a method was developed based on the Hough transform for pointer instrument identification. The gauge board image was gained from CCD and transformed into digital signal, extracting two pointers by adjusting the image resolution with Image Subtraction. By using Hough transformation to peak detection, line detection and link,with transferring the position of the baseline, the date of point instrument has been identified. The higher precision of the operator has been proved by the experiment. And the maximum uncertainty of the pointer's position in the analog instruments is less than the discrimination of the human eye.关键词
