Abstract
Data from a radar sensor moving through a static environment may be smoothed and used to generate range profiles by approximating peaks. A direction of arrival (DOA) can then be determined based on the range profile in order to generate a reprojection map. The reprojection map is used to provide updates to a stored map in a robot.
Claims20
An autonomous device comprising:
- a radar;
- a processor;
- and
- a memory, storing instructions which when executed by the processor causes the processor to:
- receive raw radar data from the radar;
- approximate a peak from the received raw radar data;
- determine a direction of arrival based on the approximated peak;
- generate a reprojection map based on the direction of arrival and the approximated peak;
- and
- update a map with the reprojection map.

A system for updating a map, the system comprising:
- a radar;
- a processor;
- and
- a memory, storing instructions which when executed by the processor causes the processor to:
- receive raw radar data from the radar;
- approximate a peak from the received raw radar data;
- determine a direction of arrival based on the approximated peak;
- generate a reprojection map based on the direction of arrival and the approximated peak;
- and
- update a map with the reprojection map.
7 more elements
A non-transitory computer readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:
- receive raw radar data from a radar;
- approximate a peak from the received raw radar data;
- determine a direction of arrival based on the approximated peak;
- generate a reprojection map based on the direction of arrival and the approximated peak;
- and
- update a map with the reprojection map.
