摘要：本文在工程图纸矢量化中引入了平均链码和线条的概念,提出了线条轮廓跟踪的原理.平均键码可以表征直线的方向、确定边界的走向和折点的位置.利用线条概念设计出的搜寻跟踪起点、截断折线和跨越交叉线的方法,实现了工程图纸上直线或微弯曲线的直接跟踪.
This paper gives new difinitions of line and average chain code. The mechanism of engineering drawing vectorization based on line tracking is proposed. Average chain code can be used to indicate direction of straight line, judge the trend of line, determine the broken point and so on. Based on the concept, of line, we design a approach to search the starting point for tracking, cut turning lines, jump crossing lines and realize thd direct tracking of straight lines or smoothly bending lines. This method can greatly decrease the number of tracked lines and improve the quality of vectorization. Because of no thinning, it can decrease errors, obtain line wide and have a higher processing speed.
