摘要：

This paper presents the methods for preprocessing and vectorizing scan digitized images of engineering drawings for transferring the resulting data to commercially available CAD/CAM systems. The preprocessing steps include noise removal, void filling, image segmentation, line thinning, and contour extraction. Algorithms for raster-to-vector conversion capable of recognizing and fitting straight line segments, circles, arcs, and conic sections are presented along with results obtained from images of machine drawings. © 1990.
