Examination System In The Auto Meter Based On Image Processing

The traditional detecting missing dial on Auto-Meter is carried on through a artificial way. Mainly, the workers detect the missing dial through eyes to measure the positions of dial. The traditional method completely depends on the workers and is inefficiency. This paper mainly introduced an automatic measurement of missing dial on the Auto-Meter .Firstly, the basic knowledge about image processing and Auto-Meter was introduced. After a deep analysis on how to use an image processing system to detect the missing dial on Auto-Meter , we design the whole system combined with the actual conditions of Auto-Meter. Afterwards we expound the whole system's hardware and software particularly. This paper had an emphasis on the algorithm of image processing. The measurement to confirm the area to image processing, edge detection, randomized Hough transform to line detecting were detailed explains. Finally, this paper introduced the system running status in laboratory, detailed analyzed measuring data and summarized problems encountered in field. At last, this paper summarized the study and pointed out the development of detecting missing line on Auto-Meter in future.
