How to align Area_5a and Area_5b? #40

Hi,

Thanks for your great work. However, I was confused about the split mesh of Area_5.

  1. These 2 meshes seem not to be aligned in the same coordinate system. If I sample some points from two mesh and stack them together. Obviously, it's not recovered to complete Area_5 as expected.
  2. In the Area_5a, and Area_5b, some of the rooms has been split into two meshes. But for one side, it might be a single wall, while it would contain the most part of the room. This is to say we can't use the mesh separately as they're not complete if we don't stitch them together. However, it's not aligned.

Hi @ZhengdiYu,

Did you find any solution to align Area_5a and Area_5b? I also have the same problem. I would appreciate it if you could provide me with some ideas to solve this problem.

Best wishes, Heming

How did you find the offsets? Did you use ICP?
