Sparse GPU Voxelization for 3D Surface Reconstruction

摘要: Processes and systems described herein enable a computing device to perform voxel-based three-dimensional (3D) reconstruction modeling using parallel graphics hardware. The may generate an initial low resolution voxel list. voxels of the list be represented as index triples corresponding 3D spatial location cell within grid (e.g., {ix,iy,iz}). Based on information input images associated with object, remove certain that do not intersect surface object. remaining subdivided one or more times into number sub-voxels in new newly generated tested again determine object surface. This process repeat part. output rendered projected images.
