Abstract
An information processing device of the present disclosure includes a ranger that detects a distance to an end part of a stage and detects a predetermined pattern provided on the stage, with infrared light, and an estimator that estimates a self-location on the basis of a detection result of the ranger.
Claims11
An information processing device, comprising:
- a ranger configured to:
- detect a first distance to an end part of a stage and a specific pattern on the stage, with infrared light, wherein
- the ranger includes a plurality of ranging sensors each having a different orientation,
- each ranging sensor of the plurality of ranging sensors is configured to measure a second distance to an object within a detection plane which intersects a main axis of the each ranging sensor of the plurality of ranging sensors,
- a direction of the main axis of the each ranging sensor of the plurality of ranging sensors is different from a vertical direction of a stage surface of the stage,
- the plurality of ranging sensors include at least three ranging sensors, and
- a plurality of lines at which the detection plane of the each of the plurality of ranging sensors intersects the stage surface form a regular polygon;
- and
- a processor configured to:
- estimate a self-location based on a detection result of the ranger;
- and
- determine, based on the estimated self-location, a movement plan to move a moving apparatus that includes the information processing device.
