WebApr 15, 2024 · The 3D geometry understanding of dynamic scenes captured by moving cameras is one of the cornerstones of 3D scene understanding. Optical flow estimation, visual odometry, and depth estimation are the three most basic tasks in 3D geometry understanding. In this work, we present a unified framework for joint self-supervised … WebSep 30, 2024 · Since the coordinate reprojection and sampling operations are both differentiable, the depth and pose estimation models can then be trained by minimizing the photometric errors between the reconstructed and the original target frames. A widely-adopted loss function in the literature combines the L1 loss and the SSIM measurement …
