Position identification system, transport vehicle, position identification method and recording medium

Abstract

A position identification system includes a point group acquisition partthat horizontally irradiates light into a space above a loading platform Ta to acquire a point group PG, an analysis part, and a position identification part. The analysis part analyzes the acquired point group PG using frequency distribution with a distance in the X-axis direction as an axis. The position identification part identifies a region Dwith substantially no frequency as a cargo placing space based on an analysis result of the point group PG, and identifies sections Sand Swith a predetermined frequency or more adjacent to the cargo placing space as the positions of edges in the X-axis coordinate of an object adjacent to the cargo placing space.
