Unsupervised Learning of 3D Scene Flow from Monocular Camera. (arXiv:2206.03673v1 [cs.CV])

Scene flow represents the motion of points in the 3D space, which is the
counterpart of the optical flow that represents the motion of pixels in the 2D
image. However, it is difficult to obtain the ground truth of scene flow in the
real scenes, and recent studies are based on synthetic data for training.
Therefore, how to train a scene flow network with unsupervised methods based on
real-world data shows crucial significance. A novel unsupervised learning
method for scene …
