摘　　要：为了更加快速地检测直线的倾角,提出了一种新的检测方法.该方法对细化后的直线轮廓进行遍历,计算直线上点的方向码的平均值,并加入误差补偿,最终获取直线的倾斜角度.试验结果表明:使用文中方法检测到的角度误差很小,而且检测所需要的时间与直线的倾角范围无关.In this paper, a new algorithm used to measure the skew angle of lines is proposed.In the algorithm, the average value of direction code is computed after traversing the thinned skeleton of a line, then an error compensation is added to the average value, the final result is the skew angle of the line.At last the test proves the error of skew angle of lines measured by the algorithm to be very small, and the measuring time is independent of the skew angle range and detection precision of lines.
