摘要
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。
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.
