摘要


利用2个非平行的长方体作为标定模版,采用Hough变换检测出图像中长方体的棱,然后计算出2组三正交方向上的消影点,再根据消影点与摄像机内参数的约束方程求出摄像机内参数.该方法原理简单,只需要一幅图像就可实现摄像机内参数的求解.实验结果表明,该方法有较高的精度和稳定性. Using two non-parallel cuboids as a calibration pattern, detecting the edges of the image by using Hough transform, and then computing the three orthogonal vanishing points of the two cuboids in two groups on the image, the intrinsic parameters can be obtained from the constraint equations. The method is simple and only one image is enough to compute the cameras intrinsic parameters. The results of the experiment show that this approach has fairly high precision and stability.
