Abstract
A method, computer program, and computer system is provided for processing point cloud data. Quantized point cloud data including a plurality of voxels is received. An occupancy map is generated for the quantized point cloud corresponding to lost voxels during quantization from among the plurality of voxels. A point cloud is reconstructed from the quantized point cloud data based on populating the lost voxels.
Claims20
A method of point cloud processing, executable by a processor, comprising:
- receiving quantized point cloud data including a plurality of voxels;
- generating an occupancy map for the quantized point cloud corresponding to lost voxels during quantization from among the plurality of voxels;
- and
- reconstructing a point cloud from the quantized point cloud data based on populating the lost voxels.
A computer system for point cloud processing, the computer system comprising:
- one or more computer-readable non-transitory storage media configured to store computer program code;
- and
- one or more computer processors configured to access said computer program code and operate as instructed by said computer program code, said computer program code including:
- receiving code configured to cause the one or more computer processors to receive quantized point cloud data including a plurality of voxels;
- generating code configured to cause the one or more computer processors to generate an occupancy map for the quantized point cloud corresponding to lost voxels during quantization from among the plurality of voxels;
- and
- reconstructing code configured to cause the one or more computer processors to reconstruct a point cloud from the quantized point cloud data based on populating the lost voxels.
A non-transitory computer readable medium having stored thereon a computer program for point cloud processing, the computer program configured to cause one or more computer processors to:
- receive quantized point cloud data including a plurality of voxels;
- generate an occupancy map for the quantized point cloud corresponding to lost voxels during quantization from among the plurality of voxels;
- and
- reconstruct a point cloud from the quantized point cloud data based on populating the lost voxels.
