POSITION SPECIFICATION DEVICE, PROGRAM AND POSITION SPECIFICATION METHOD

PROBLEM TO BE SOLVED: To provide a position specification device capable of easily specifying a position of a lighting device of the corresponding device ID.SOLUTION: A position specification device includes: an acquisition part; and a specification part. The acquisition part acquires lighting intensity information showing three lighting intensity obtained by measuring light outputted by a lighting device at three different measurement positions. In the specification part, the position of the lighting device is specified from three distances between the position of the lighting device and three measurement positions which are specified from lighting intensity distribution obtained by associating the lighting intensity with the distance, and the three measurement positions.SELECTED DRAWING: Figure 1 【課題】該当する装置ＩＤの照明装置の位置を容易に特定できる位置特定装置を提供する。【解決手段】位置特定装置は、取得部と、特定部と、を備える。取得部は、照明装置が出力した光を、異なる３個所の測定位置で測定した３個の照度を示す照度情報を取得する。特定部は、照度と距離とを関連付けた照度分布から特定した、前記照明装置の位置と前記３個所の測定位置との間の３個の距離と、前記３個所の測定位置とから前記照明装置の位置を特定する。【選択図】図１
