MAP PRODUCTION METHOD, MOBILE ROBOT, AND MAP PRODUCTION SYSTEM

摘要

There is provided a map production method to be performed by a mobile robot which moves in a first region and includes a first sensor and a second sensor. The map production method includes acquiring first information from the first sensor, acquiring second information from the second sensor, acquiring third information from a third sensor provided in the first region, acquiring fourth information indicating a detection region of the second sensor calculated from the first information and the second information, acquiring fifth information indicating a detection region of the third sensor calculated from the third information, and updating map information of the first region for a third region, including a first object, if a the second region overlaps with the third region is judged to be present from the fourth information and the fifth information.

1. A map production method to be performed by a first mobile robot which moves in a first region and includes a first sensor and a second sensor, the map production method comprising:
acquiring first information from the first sensor, the first information indicating an amount of movement of the first mobile robot; acquiring second information from the second sensor, the second information indicating a distance from a first object present in an observation region of the first mobile robot to the first mobile robot; acquiring third information from a third sensor provided in the first region, the third information including video information of an observation region of the third sensor; acquiring fourth information indicating a detection region of the second sensor which is calculated based on the first information and the second information; acquiring fifth information indicating a detection region of the third sensor which is calculated based on the third information; judging, based on the fourth information and the fifth information, whether a second region where the detection region of the second sensor overlaps with the detection region of the third sensor is present; and updating map information of the first region which is stored in advance in the first mobile robot for a third region, including the first object if the second region is judged to be present.
