摘要 介绍了一种改进的基于梯度方向角圆检测的方法。解决了鉴别阶段随机引入第三点造成的大量无效积累,致使运算复杂的问题。首先采用分层预处理减少参与鉴别阶段的点,然后在鉴别过程中采用新方法,无需引入第三点,利用两点若为圆直径两端点,那么两点确定的线段中点即为圆心,线段长度即为直径。以圆心为基点间隔一定角度扫描,通过线段端点与待鉴别圆的交点个数验证圆。实验结果表明,该方法计算量小,检测性能比之前者显著提高,且鲁棒性好,在多圆叠加情况下效果更加突出。 An improved circular detection method based on gradient direction angle was introduced in this paper. In the differential really round stage, by introducing the third point of random caused to accumulate a large number of invalid data and leave compute complex issue are resolved. Firstly layered image reduce unnecessary point, secondly use of new methods, if the two points are the circle diameter's end points, then two points determine the line whose midpoint is the center of the circle, and length of the line is the diameter. Center anchored by an interval of scan angle, through the number of the intersection which is endpoints and the image whether the conditions established. Contrast experimental results show that the new method consumes time shorter than before and has a good robustness. In many circles under the superimposition effect is more outstanding.
