The Measurement of Abrasive Wear Based on Computer Vision

To measure the height and wear of the diamond abrasive, a new technique based on computer vision is presented in this paper. Firstly, the computer vision system is designed. The height evaluation of abrasives and the calibration of the imaging set-up are introduced in detail. Secondly, we adopt the sequential similarity detection algorithm to get corresponding pixels in the left and right image. Finally, the heights and wear of the grain are obtained by calculating their parallax on left and right images. The experiment of standard block shows that the relative error is less than 5%.
