Abstract
A position estimation system is a position estimation system for estimating a position of a forklift equipped with a camera and includes: a position estimation unit configured to estimate a position of the forklift on the basis of a feature included in an image captured by the camera; and an inclusion determination unit configured to calculate, on the basis of a position in a height direction of a mast with which the forklift is equipped, an inclusion range indicating a range in which the mast is in the image and determine to stop estimation of the position by using the position estimation unit when the inclusion range calculated exceeds an allowable range.
