A novel global optimization approach to accurately colorize LiDAR point clouds by jointly optimizing the poses of 360-degree camera frames to maximize photometric consistency.
The core message of this paper is to propose a novel Tightly Coupled LiDAR-Camera Gaussian Splatting (TCLC-GS) framework that synergizes the strengths of LiDAR and surrounding cameras to achieve fast 3D modeling and real-time RGB/depth rendering in urban driving scenarios.
