Re: PCD data scale become smaller

Hi Daniel. I did as you suggested. But it still did not produce the correct georeference. What I did is flatten the pcd (z: 0), register coordinates local, and truncated global coordinates. scale up pcd to 100 times for all dimensions, and apply transformation (translate: x; 2.6, y; 101.6). Did I mi...

Re: PCD data scale become smaller

Ah, I understand now. Since all the Z coordinates of your reference points are 0 (= 2D points), and you tell CC to scale the align cloud (3D) to best fit the points, it ends up rescaling the aligned points with a ridiculously small scale (so that 'P.z * 0 = 0' basically). You can't align 3D points ...

Re: PCD data scale become smaller

Can you give us an example of coordinates you use? Aren't they very large? Normally, CC should suggest to apply a Global Shift in this case. Did you see any such question? I'm not sure if it's large or not. The local coordinates in PCD are as follows: -88.459938, 2.612011, 5.125117 14.940063, 4.112...

PCD data scale become smaller

Hi. I'm really new here in CloudCompare, georeference, and other general stuff. So please apologise if my question is simple. I just learned how to align one cloud with the real coordinates. When I finish pointing the coordinates, I click align and press Enter, it becomes like this. pcd-blurry-1.png...
