GRIP: Gaussian Rendering as a Cross-Modal Bridge for Image-to-Point Cloud Registration

This paper introduces GRIP, a pose-conditioned refinement framework for pixel-to-point matching and 2D to 3D registration. Given an initial coarse pose estimate, GRIP addresses the structural mismatch between grid based image descriptors and unordered point cloud descriptors by softly rendering learned 3D point feature...
