在激光雷达和相机的标定中,我们常会用到重投影误差(Reprojection error)。之所以使用重投影误差,是因为它不光考虑了投影矩阵的计算误差,也考虑了图像点的测量误差,所以其精度会更高。 如何理解重投影误差? 当我们得到一组雷达与相机的标定结果,我们可以将雷达坐标系中的一点通过标定结果投影到相机坐标系下,比较相机坐...

For these cases, this paper presented a two-step calibration based on soft constraint optimization, which is motivated by "no free lunch" theorem and error analysis. The key steps include (1) homography estimation with weighting function, (2) Initialization based on a simplified model, and (3...
