Hi, thanks for releasing v1.2 label files. I have one question about the relationship among "xyz", "visibility" and "uv".
In v1.1, for one single lane, sum(visibility) = len(xyz[visibility]) = len(uv) (pseudo python code). Therefore, each 3D point has its corresponding 2D point.
However, in v1.2, this relationship no longer exists. I found that sum(visibility) = len(xyz[visibility]) <= len(uv). If I want to find corresponding 3D and 2D points, should I use uv and reproject them to 3D coord, or use xyz and project them to 2D coord? Thanks!
