In order to solve such problems that difficult adaptation of the illumination change during the recognition on the fine pointer dial, difficult segment of the fine pointer and low accuracy of the dial reading recognition , combined with the image characteristics of the fine pointer dial area, a image processing method is proposed to calculate the reading of the fine pointer dial. Firstly, the dial is calibrated, the prior data such as the dial range is obtained, the template is created, and the multi-task template feature matching algorithm based on SURF algorithm is proposed. Secondly, according to the pointer active area, a pointer positioning method based on the segmented sector (PSS) is proposed to locate the pointer. Through the image preprocessing and binarization, the angle is calculated using the least squares method. Finally, the reading is obtained based on the pointer angle. The experimental results show that the presented method has a high, accurate, and stable recognition rate for the fine pointer dial.
