Research on On-line Visual Measurement Method of Guide Slide Size Based on Improved Canny Edge Detection Algorithm
In this paper,a method for measuring the size of guide slide block based on improved Canny edge detec-tion algorithm is proposed.Through OpenCV machine vision library,the image processing algorithms such as Gauss-ian smoothing,adaptive double threshold segmentation and Hough transform are used to process the image of the guide rail,and the online accurate measurement of the raceway spacing in the sliding block of the rolling linear guide rail is realized.At the same time,the feasibility of visual measurement method is discussed and analyzed.
