Position identification device and mobile robot provided with same
First Claim
1. A position identification device to be mounted in a mobile body, that includes a distance sensor for measuring a distance to a surrounding object of the mobile body, and estimates a position and an angle of the mobile body, by using map data of a surrounding environment and distance data that is measured by the distance sensor, the position identification device comprising:
- specific area storage means for storing a place where a specific object as a target of a transport request is present as a specific area in the map data; and
object determination means for determining whether or not the object is present within the specific area, by using the map data and the estimated position and angle, and for determining whether or not the object determined to be present within the specific area is the specific object, by specifying an approximate size of the object from the distance data.
