“…The feature extraction methods for alignment correction involve the use of a line [ 1 , 2 ], integral histograms [ 3 , 4 ], projection-based integral histograms [ 5 ], the long axis [ 6 ], Hough Line-based reference feature extraction [ 7 ], Harris Corner-based feature extraction [ 8 ], and Moravec Corner-based feature extraction [ 9 ]. The method involving the use of a line, which is a feature included in the part, has the advantage of rapidly correcting the alignment of products with line components; however, it is difficult to apply to round-shaped parts.…”
