To provide a position calculation system which can calculate a position of an unmanned carrier even if it is impossible to detect a plurality of reflection sources with known positions provided at stationary bodies.SOLUTION: A position calculation system according to the present invention has a management unit for managing a current position of each of a plurality of unmanned carriers, and a position calculating unit calculating a position of a target unmanned carrier based on a result of detection by a laser measurement device mounted on the target unmanned carrier of reflection light reflected from each of reflection sources of a predetermined number that is two or more and allowing acquisition of positional information. If the reflection sources of the predetermined number from which the reflection light is detected includes an on-vehicle reflection source mounted on unmanned carriers other than the target unmanned carrier, the position calculating unit acquires the positional information of the on-vehicle reflection source based on the current position managed by the management unit to calculate the position of the target unmanned carrier.SELECTED DRAWING: Figure 1

    【課題】静止体に設置された位置が既知となっている複数の反射源が検出できない場合であっても無人搬送車の位置を算出可能な位置演算システムを提供する。【解決手段】位置演算システムは、複数の無人搬送車の各々の現在位置を管理する管理部と、対象の無人搬送車から見て互いに異なる方向に位置する、位置情報が取得可能な2以上の規定個数の反射源の各々からの反射光を、対象の無人搬送車に搭載されたレーザ計測器により検出した検出結果に基づいて、対象の無人搬送車の位置を算出する位置算出部とを備え、位置算出部は、反射光が検出された規定個数の反射源に、対象の無人搬送車以外の他の無人搬送車に搭載されている搭載反射源が含まれている場合には、管理部で管理されている現在位置に基づいて搭載反射源の位置情報を取得して、対象の無人搬送車の位置を算出する。【選択図】 図1
