coordinate system comparing to Omnidatav2 normal estimation.

[miangoleh]

I was wondering if the coordinate system you describe is the same as the coordinate system used in omnidata v2 which you are comparing against.

Was asking myself the same question... Found that both Omnidata and 2D3GS share similar conventions but couldn't find it yet for DSINE..

Hi! Sorry for the late reply. As mentioned in the README:

We use the right-handed coordinate system with (X, Y, Z) = (right, down, front). An important thing to note is that both the ground truth normals and our prediction are the outward normals. For example, in the case of a fronto-parallel wall facing the camera, the normals would be (0, 0, 1), not (0, 0, -1). If you instead need to use the inward normals, please do normals = -normals.

I hope this helps!
