Abstract: This invention provides a system and method for generating a dense, visibility-aware 3D occupancy grid from LiDAR data to enhance spatial perception in autonomous driving. The system comprises a voxel densification module that aggregates sequential LiDAR frames, a K-nearest neighbors algorithm for label propagation, and a mesh reconstruction process to fill sparse regions. An occlusion reasoning module classifies each voxel as occupied, free, or unobserved through LiDAR-based ray-casting. Additionally, camera image-guided refinement adjusts voxel states by aligning 3D voxel labels with 2D image pixels, ensuring accurate boundary representation and correcting for sensor noise. The resulting occupancy grid includes general objects outside predefined categories, enabling more robust obstacle detection. This system significantly improves autonomous navigation by enhancing object recognition, boundary accuracy, and overall environmental understanding.
