To measure a space between buildings in a hoistway, especially a steel frame and a fastener plate installed in the steel frame, before installation of an elevator.SOLUTION: This in-hoistway measurement device hoisted by a hoist installed at the uppermost part of a hoistway comprises: a position sensor that receives a laser beam vertically applied from the uppermost part of the hoistway and measures absolute coordinates of vertical and horizontal directions; an inclination sensor that detects an attitude in the hoistway; a horizontal distance sensor that measures a distance to a horizontal object in the hoistway and outputs point group data; a rotation stage for rotating the horizontal sensor; a camera that photographs a lower portion in the hoistway and acquires an image; an image processing unit that processes the image captured by the camera; a vertical distance sensor that measures a distance to a vertical object photographed by the camera; and a control unit that stores the output of the image processing unit and the output of the horizontal distance sensor in association with the hoisting height of the hoist.SELECTED DRAWING: Figure 2

    【課題】 エレベータの据付前に、昇降路内の構造物の間隔、特に鉄骨及び鉄骨に設置されたファスナープレートを計測する。【解決手段】 昇降路の最上部に設置した巻上機によって昇降する昇降路内計測装置であって、前記昇降路の最下部から鉛直上方に照射したレーザ光を受光し、前後方向と左右方向の絶対座標を計測する位置センサと、前記昇降路内における姿勢を検出する傾斜センサと、前記昇降路内の水平方向の対象物との距離を計測し、点群データを出力する水平距離センサと、該水平距離センサを回転させる回転ステージと、前記昇降路内の下方を撮影し画像を取得するカメラと、該カメラが撮影した画像を処理する画像処理ユニットと、前記カメラが撮影する垂直方向の対象物との距離を計測する垂直距離センサと、前記画像処理ユニットの出力および前記水平距離センサの出力を前記巻上機の巻き上げ高さと関連付けて保存する制御ユニットと、を備えた昇降路内計測装置。【選択図】 図2
