Stereo4D: Learning How Things Move in 3D from Internet Stereo Videos

Use stereo videos from the internet to create a dataset of over 100,000 real-world 4D scenes with metric scale and long-term 3D motion trajectories.

This type of data is ideal for learning the structure and dynamics of the real world. We gave this a shot — by extending DUSt3R to model 3D motion, and training on our dataset. Given a pair of frames, our model predicts a 3D point cloud, and corresponding 3D motion trajectories.

Introducing 👀Stereo4D👀 A method for mining 4D from internet stereo videos. It enables large-scale, high-quality, dynamic, *metric* 3D reconstructions, with camera poses and long-term 3D motion trajectories. We used Stereo4D to make a dataset of over 100k real-world 4D scenes.
