针对指针式指示表的自动判读,介绍了指针式指示表的自动读取及MATLAB仿真。计算机获取指示表数字图像后,首先对图像进行预处理,包括图像平滑、图像分割及膨胀细化等步骤,然后通过Hough变换提取出指针所在的位置,通过图形用户界面把度数显示出来,最后利用表盘刻度与角度对应的线性关系得到指针读数。
針對指針式指示錶的自動判讀,介紹瞭指針式指示錶的自動讀取及MATLAB倣真。計算機穫取指示錶數字圖像後,首先對圖像進行預處理,包括圖像平滑、圖像分割及膨脹細化等步驟,然後通過Hough變換提取齣指針所在的位置,通過圖形用戶界麵把度數顯示齣來,最後利用錶盤刻度與角度對應的線性關繫得到指針讀數。

According to the recognition of pointer indicator ,the recognition of indicator ’ s reading and simulation of MATLAB is introduced.After computer obtained indicator ’ s digital images,first the image should be pre-processed,including image smoot-hing、image segmentation and expansion refining etc ,then,pass the location of the pointer distilled by the Hough transformation , get the pointer degrees used by the liner relation of the dial scale and its proper angular .Finally,display the result from using the graphical user interface .
