Abstract
A calibration method performed by a distance sensor emitting at least one beam is provided. The calibration method includes obtaining information regarding one surface of an object; obtaining distance sensor data by emitting a plurality of beams to the one surface of the object; and performing calibration on the plurality of beams emitted by the distance sensor, based on the information about the one surface of the object and the distance sensor data.
Claims21
A calibration method performed by a distance sensor, the calibration method comprising:
- obtaining information about one surface of an object;
- obtaining distance sensor data by emitting a plurality of beams from the distance sensor to the one surface of the object and receiving a plurality of reflection signals of the plurality of beams;
- and
- performing calibration on the plurality of beams emitted by the distance sensor, based on the information about the one surface of the object and the distance sensor data,
- wherein the obtaining the information about the one surface of the object comprises:
- obtaining a first reflection result at a first location and a second reflection result at a second location,
- obtaining movement information of the distance sensor based on the first reflection result and the second reflection result, and
- obtaining the information about the one surface of the object based on the movement information of the distance sensor, the first reflection result, and the second reflection result.
A distance sensor comprising:
- a sensing unit configured to emit a plurality of beams and receive a plurality of reflection signals of the plurality of beams;
- and
- a processor configured to:
- obtain information about one surface of an object,
- control the sensing unit to obtain distance sensor data by emitting the plurality of beams to the one surface of the object and receive the plurality of reflection signals of the plurality of beams, and
