| 摘 要： | Hough变换在指针式仪表判读中的应用含读数的判读以及误差分析两步.前者步骤包括:利用CMOS摄像头采集获取原始图像,对图像进行增强和滤波处理,完成平滑滤波和中值滤波,并找出秒针、分针、时针对应的三个局部最大值,采用Hough变换判读手表读数;后者则根据相应公式估算分针和时针的读数误差,其自动判读系统可精确到一个像素.

| Abstract: | Application of Hough transform to reading determination of dial instrument includes reading determination and error analysis.The former includes: the CMOS pickup camera was used to sample the original images;the pictures were processed by intensifying and filtering;the smooth filter and middle-value filter were accomplished;the partial maximums of second hand,minute hand and hour hand were found;at last the reading determination was achieved through Hough transform.The precision grade of automatic determination system can certain the pixel. |
