请问相机的K,D,该如何获取啊? #2
Comments
四个系数应该是鱼眼相机的畸变系数D = [k1,k2,k3,k4],matlab自带的鱼眼相机标定工具箱应该还可以得到相机内参K,K的形式为:[[fx, 0, cx], [0, fy, cy], [0, 0, 1]]。另外也可以试一下opencv的鱼眼相机标定函数 |
请问你们的K是统一球面模型的最后直射变换的的相机内参K吗?另外[k1,k2,k3,k4]] 是只考虑了径向畸变? |
K是统一球面模型的最后直射变换的的相机内参K,在不考虑扭曲的情况下可以简化为K = [[fx, 0, cx], [0, fy, cy], [0, 0, 1]] |
哦哦哦,谢谢啦,我那个matlab的工具箱确实没用错,相机内参就那几个参数(笑哭),我挺奇怪的 |
鱼眼相机的这块的标定有点搞不清楚,我用matlab工具箱标定只获取了四个投影系数,这四个系数是代表径向畸变系数吗?请问有什么好的标定方式可以介绍吗,万分感谢
