| Abstract: | As to the identification and calibration of index-instrument,a novel method for reading recognition based on digital image processing is proposed.Firstly,preprocessing operation on images is done,including image segmentation,image filtering,image dilation and thinning etc,and a method of improved adaptive median filter is adopted to improve the image.Then,characteristic information of image is extracted with the improved dual thresholds Hough transformation,and the pointer reading is got using the linear re... |
