摘要
提出了一种求解等边三角形及其内切圆的图像圆环点坐标新方法。通过提取模板图像的角点,利用高等几何中的拉盖尔定理及其推论来计算其图像圆环点坐标,实验数据证实了该方法的有效性。利用该方法求得的坐标值可以用于摄像机的标定等领域。
A new method for solving the coordinates of circular points in an image of an equilateral triangle and its inscribed circle was proposed. Through corner extraction of the template image, the coordinates of circular points could be calculated by using Laguerre theorem and its inference of higher geometry. The experimental data proves the validity of this method. The coordinates calculated by this method can be used for calibrating cameras and other fields.
