PROBLEM TO BE SOLVED: To simplify a system configuration and image processing, and to calculate an error between a dimension of an object portion and a design dimension with high accuracy.SOLUTION: A dimension measurement system comprises: an imaging part disposed at a predetermined position for imaging a work disposed at a reference position from a predetermined imaging direction; and a server for acquiring an imaging result by the imaging part via an electric communication line, and for calculating a dimension of an object portion as a part of the work on the basis of the acquired imaging result and information on the imaging position and the imaging direction, and for calculating an error between the calculated dimension of the object portion and a design dimension of the object portion.SELECTED DRAWING: Figure 1 【課題】システム構成及び画像処理の簡略化を図ることができ、対象部分の寸法及び設計寸法との間の誤差を高精度に算出する。【解決手段】寸法計測システムは、所定の撮像位置に配置され、基準位置に配置されたワークを所定の撮像方向から撮像する撮像部と、電気通信回線を介して前記撮像部での撮像結果を取得し、取得した前記撮像結果と前記撮像位置及び前記撮像方向に関する情報とに基づいて前記ワークの一部である対象部分の寸法を算出し、算出した前記対象部分の寸法と前記対象部分の設計寸法との間の誤差を算出するサーバと、を備える。【選択図】図１
