PROBLEM TO BE SOLVED: To provide an in-hoistway dimension measurement device which can measure the dimensions of each part in the hoistway of an elevator without requiring the installation of a large measurement device and the actual measurement work by a worker.SOLUTION: A measurement device 1 of the invention includes: a distance image camera 2 which can recognize the distance to an object in a photographing range as an image; a height calculation part 14 for calculating the height of the inside of a tower when photographing each image to create a solid figure from images photographed by the distance image camera 2; a rotation angle detection part 15 for detecting a photographed angle; an image correction part 5 for correcting a photographed image; a feature extraction part 6 for extracting a part having the feature of a photographed image; a feature matching part 7 for finding parts having the same feature on the basis of an extracted feature; a solid synthesis part 8 for creating a solid figure by connecting images on the basis of the same feature among the plurality of images; and a dimension calculation part 9 for calculating the dimensions of each part on the basis of the solid figure created by the solid synthesis part 8.SELECTED DRAWING: Figure 1
【課題】大掛かりな測定装置の設置や、作業員による実測作業を要することなく、エレベータの昇降路内の各部の寸法を測定することができる昇降路内寸法測定装置の提供。【解決手段】本発明に係る測定装置1は、撮影範囲の物体との距離を画像として認識できる距離画像カメラ2と、この距離画像カメラ2の撮影画像から立体図形を作成するために、各画像を撮影したときの塔内高さを計算する高さ計算部14と、撮影した角度を検出する回転角検出部15と、撮影画像を補正する画像補正部5と、撮影画像の特徴を有する部位を抽出する特徴抽出部6と、抽出した特徴に基づいて同一の特徴を有する部位を見つける特徴一致部7と、複数の画像間で同一の特徴に基づいて画像を繋ぎ合せて立体図形を作成する立体合成部8と、この立体合成部8で作成された立体図形に基づいて各部の寸法を計算する寸法計算部9とを備えている。【選択図】図1
