Unsupervised Learning of 3D Scene Flow with 3D Odometry Assistance. (arXiv:2209.04945v1 [cs.CV])

Scene flow represents the 3D motion of each point in the scene, which
explicitly describes the distance and the direction of each point's movement.
Scene flow estimation is used in various applications such as autonomous
driving fields, activity recognition, and virtual reality fields. As it is
challenging to annotate scene flow with ground truth for real-world data, this
leaves no real-world dataset available to provide a large amount of data with
ground truth for scene flow estimation. Therefore, many works …
