Query regarding Ground Truth & 3D Convention #31

Closed libaiwanovo closed 11 months ago

libaiwanovo commented 11 months ago

Thank you and your team for the excellent code.

1) How is the ground truth obtained for your dataset?

2)The generated point cloud is based on what coordinates?

Looking forward to your reply！

Hi, Thanks for your queries!

  1. We use the ARKit poses as Ground Truth for the iPhone demo.
  2. The coordinate system is the first frame (everything is relative to the first frame).
