Abstract
A position calculation system includes a managing unit managing a current position of a plurality of automated guided vehicles; and a position calculating unit calculating a position of the target automated guided vehicle based on a detection result, detected by the laser measuring device mounted on the target automated guided vehicle, of detecting each reflection light reflected from a specific number being two or more of reflection sources, position information of which is obtainable, existing at positions on mutually different directions viewing from the target automated guided vehicle. Here, when the reflection sources with the reflection light therefrom detected include a mounted reflection source mounted on another automated guided vehicle other than the target automated guided vehicle, the position calculating unit obtains the position information of the mounted reflection source based on the current position managed by the managing unit, and calculates a position of the target automated guided vehicle.
