1、In multi camera training, do you only use spatio-temporal loss or temporal + spatio-temporal loss?
2、In multi camera training, do you use COLMAP depthmap supervise？

abing222 commented

"By introducing spatial contexts (Equation 3), we not only further improve performance, but also learn scale-aware models by leveraging the camera extrinsics", What does scale-aware mean?

VitorGuizilini-TRI commented
  1. We use spatial + temporal + spatio-temporal
  2. We do not use COLMAP supervision

Scale-aware means that the pointclouds are metrically accurate (i.e. estimates are in meters).

I hope that helps!

thank you very much，In my experiment，without additional supervision, due to the introduction of camera external parameters, the scales of space and temporal are inconsistent (absolute scale and relative scale), resulting in poor model training results
