A Subpixel On-line Inspection Technology for Bore Diameter of Bearing Based on Machine Vision
Xiaorui Zhang · Bearing Jurnal Penelitian dan Kajian Teknik Sipil · 2007
Based on machine vision system,an algorithm for circle subpixel edge detecting based on point Hough transform is adopted for the pre-processed edge image,by virtue of computer image processing technology.And a subpixel detection technology for the bore diameter of bearings is realized successfully on-line.The experiments demonstrate that the system has many advantages such as non-touching,high speed,low cost,and so on,and the method is universal so that can be applied widely to on-line inspection of other products.
