LDI-3DGS: Structurally Robust 3-D Gaussian Splatting Driven by UAV-Borne LiDAR Depth and Intensity Priors
3-D Gaussian splatting (3DGS) has demonstrated outstanding performance in novel view synthesis and 3-D scene reconstruction. While 3DGS can technically be optimized from random initialization, achieving high-quality and scale-accurate reconstruction in large-scale scenes still relies heavily on sparse structure-from-mo...
