Sep16 comment Correcting plane parameters with the fixed azimuth angles any possibility to rotate a plane till its azimuth reach 90 degree difference with the adjacent one while preserving its "d" in the same value? Sep16 comment Correcting plane parameters with the fixed azimuth angles yes, I got your explanation and thank you very much for that. But, to find the average apex, first i should have the intersected lines. But, first, i want to adjust the planes in a way to get their XY projected normal vector in a more regualr mannar (i.e. 90 degree difference). for that, i can find a starting plane by finding the plane having many points or smallest rmse. if you dont mind, would it be possible to explain a way to update these planes. (accordig to my undestanding for the suggest way, i need to know the lines, but practically i am not computing them till they adjust) Sep16 revised Correcting plane parameters with the fixed azimuth angles deleted 146 characters in body Sep16 revised Correcting plane parameters with the fixed azimuth angles deleted 2 characters in body Sep16 asked Correcting plane parameters with the fixed azimuth angles Jul12 comment Obtaining Least square adjusted single line by intersecting many 3D planes to be honest, the implementation of second part is still confusing me. What should I actually tested? what do you mean by last sentence. please be kind enough to simplify this problem again. thank you Jul7 comment my plane is not vertical, How to update 3D coordinate of point cloud to lie on a 3D vertical plane thank you, it works.
