摘要：
In order to quickly obtain the two-dimensional distributions of full-field abrasive grains on grinding wheel, a rapid inspection system was established based on a linear array camera. The principles of the inspection system, the acquisition of clear picture without motion distortion and key algorithms of the image processing were studied. First, the hardware structure and the working principles of the inspection system were analyzed. Then, the Sobel operator of the eight-direction template and standard parts were used to complete the camera focusing and motion distortion image rectification. Then, the image was pretreated and the image after pretreatment was segmented by improved Otsu operator. Finally, the real coordinates and equivalent area of each abrasive grain was extracted. The experiments for a grain distributed single layer brazed diamond grinding wheel (grain number 35/40) show that totally 77.4 seconds are needed for full-field pictures capturing and grain coordinates and areas extracting, which meets the fast inspection requirements of single layer brazed diamond grinding wheel. © 2019, China Mechanical Engineering Magazine Office.
