摘要

提出对扫描图象圆弧的定位算法。该算法分为两步：第一步对图象进行条块化，条块化就是把原图象的黑象素依据一定的条件合并若干个块；第二步就是在第一步的条件化基础上，提取候选圆弧链，进而对圆弧圆心，半径，弧的起始点和终止点进行准确定位。实验对圆弧的识别处理。

Abstract

A new approach for the location of circular arcs in scanned drawings is proposed in this paper. It includes two main procedures: raster to block procedure and circular arc recognition procedure. In the raster to block procedure

the drawing image is split up into primary components (blocks) which are composed of connected black pixels. Based on the blocks

several candidate circle (arc) links are generated and the circular arcs' centers

radius

starting points and end points are estimated in the circular arc recognition procedure.
