Title:
AUTONOMOUSLY TRAVELING CLEANER AND MAP CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/049657
Kind Code:
A1
Abstract:
The present invention is provided with: a map generation unit (181) which, on the basis of a travel record, generates a map using the position of a reference member as a reference position in an area to be cleaned; and a longest-straight-line determination unit (182) which determines the longest-straight-line component contained in the map. The present invention is further provided with: a map arrangement unit (183) which makes the reference position of a new map match with the reference position of a past map and which arranges the respective longest-straight-line components of the maps in parallel or in one straight line; and a difference calculation unit (184) which causes movement of the new map relative to the past map multiple times and which calculates the difference between the maps for each time the movement is performed. The present invention is further provided with a reference position update unit (185) which updates the reference position on the basis of the positional relationship, of the reference position of the new map with respect to the reference position of the past map, from which the minimum difference has been obtained. Accordingly, the present invention provides an autonomously traveling cleaner capable of correctly obtaining a reference position even if the reference position is displaced.
