To provide a position measurement system which can measure a position in a measurement target region of each measurement object with a simple configuration even when there are the plurality of measurement objects.SOLUTION: A position measurement system comprises: a measurement device having a first detection unit which includes a cylindrical reflection part and a target displaying a prescribed display pattern and measures detection data including the detection direction of a measurement object, and a second detection unit which acquires an image including the measurement object in the detection direction of the first detection unit; and a calculation device which calculates coordinates of the measurement object in a coordinate system with the measurement device expanding in a measurement target region as reference on the basis of the detection data, recognizes an ID of the measurement object on the basis of the display pattern displayed on the target of the image, and generates position information associating the ID with the coordinates.SELECTED DRAWING: Figure 1 【課題】簡便な構成で、測定対象物を複数とした場合であっても、各々の測定対象物の測定対象領域における位置を測定可能な位置測定システムを提供する。【解決手段】円筒形の反射部と、所定の表示パターンが表示されたターゲットと、を備え、前記測定対象物の前記測定対象物の検出方向を含む検出データを計測する第１検出部と、前記第１検出部の前記検出方向に向け、前記測定対象物を含む画像を取得する第２検出部と、を備えた測定装置と、前記検出データに基づいて前記測定対象領域に広がる前記測定装置を基準とした座標系における前記測定対象物の座標を算出すると共に、前記画像の前記ターゲットに表示された前記表示パターンに基づいて前記測定対象物のＩＤを認識し、前記ＩＤと前記座標とを関連付ける位置情報を生成する演算装置と、を備えることを特徴とする位置測定システムである。【選択図】図１
