Title:
MAP UPDATE DEVICE AND MAP UPDATE PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/192826
Kind Code:
A1
Abstract:
In the present invention, a server (3) comprises: a feature point position estimation unit (10e) that, if position correction of an input map by a position correction unit has failed, estimates the position of a feature point for each of a plurality of the input maps, with each of the plurality of input maps as a target thereof; an accumulated data generation unit (10f) that generates accumulated data by accumulating each of the positions of the feature points of the plurality of input maps; a convergence determination unit (10g) that, on the basis of the accumulated data, determines whether the positions of the feature points have converged; a difference data generation unit (10h) that, if it is determined that the positions of the feature points have converged, generates the positions of the converged feature points as difference data; and a difference data reflection unit (10i) that updates a reference map by reflecting the difference data in the reference map.
