摘　　要：针对航空指针式仪表自动读取中的指针提取提出了一种基于计算机视觉的指针式仪表示值精确判读方法,用改进的HOUGH变换算法,大大提高了HOUGH变换直线提取的运算速度,降低了占用内存,同时减少了直线误匹配的机会,实现指针式航空仪表读数自动识别.The paper chooses computer vision technology in the digital image processing of the aviation gauge with pointer automatic recognition as a research topic. A modified HOUGH transformation algorithm to Automatic meter reading in the Aviation Instrument pointer is proposed, which greatly improves the calculating speed of linear extraction of HOUGH transformation, and reduces the memory occupied, while reducing the linear error matching opportunities. This paper proves its effectiveness in theory and practice and realizes the automatic recognition ＆the aviation gauge with pointer.
