PRISM method uses color to guide point cloud sampling for 3D reconstruction

Researchers have introduced PRISM, a new method for sampling RGB-LiDAR point clouds that leverages color information to guide the process. Unlike traditional methods that focus on spatial uniformity, PRISM allocates sampling density based on chromatic diversity, preserving regions with rich textures and high color variation. This approach aims to create sparser point clouds that retain essential features for 3D reconstruction tasks by prioritizing visual complexity over spatial coverage. AI
