I always thought camera pose estimation is necessary for 3D reconstruction, until Zequn and Stephen proved me wrong!
Introducing PreF3R, purely feed-forward 3D Gaussian Splatting without any intermediate pose estimation and COLMAP initialization.
Video in, 3D Gaussians and novel view rendering out.
Key technique: spatial memory network from Spann3R and Gaussian head supervised by pointmap loss plus photometric loss.
