Abstract
One or more embodiments of the present disclosure may relate to communicating RADAR (RAdio Detection And Ranging) data to a distributed map system that is configured to generate map data based on the RADAR data. In these or other embodiments, certain compression operations may be performed on the RADAR data to reduce the amount of data that is communicated from the ego-machines to the map system.
Claims21
A method comprising:
- quantizing points of a RADAR data packet according to a target resolution;
- determining coordinate deltas between quantized points included in one or more respective tiles of a plurality of tiles of the RADAR data packet to obtain one or more respective tile delta sets;
- and
- applying compression encoding to the one or more respective tile delta sets using one or more pre-computed encoding trees to obtain a compressed RADAR data packet.
1 more element
A processor comprising:
- one or more circuits to:
- determine coordinate deltas with respect to points of a RADAR data packet to obtain one or more delta sets;
- and
- apply compression encoding to the one or more respective delta sets using one or more pre-computed encoding trees to obtain a compressed RADAR data packet.
1 more element
A system comprising:
- one or more processing units to:
- quantize points of a RADAR data packet according to a target resolution that is based on a localization tolerance of autonomous driving operations;
- determine coordinate deltas with respect to the quantized points to obtain one or more delta sets;
- and
- apply compression encoding to the one or more respective delta sets using one or more pre-computed encoding trees to obtain a compressed RADAR data packet.
