| 摘 要： | 运用在线划图细化后的骨架上识别直线及弧的方法实现直线和圆弧的矢量化,但运算效率较低.通过将稀疏扫描及矩阵压缩与该方法相结合,只处理存储在三元组的黑色象素点,无需对白色背景点重复扫描,提高了运算速度和准确性.直线拟合后的圆及圆弧采用二次拟合,减小了数据存储量.

| Abstract: | By means of the method of recognizing lines and circular arcs on the thinned sketch, it is able to realize their vector, but the efficiency is low. Combining sparsely scanning with compressed matrix, it is possible just to deal with the black points which were stored in a three - dimensional array rather than scan white points again and again, which indubitably accelerates the calculating speed and accuracy. Impending again the circle to circular contributes to reduce the date storage. |
