To facilitate dimension measurement of a brake lining of an elevator according to a photographed image.SOLUTION: A dimension measurement system includes: a processing unit 13 which recognizes an elliptical shape or a circular shape having a maximum curvature from a photographed image obtained by photographing a brake lining around a brake drum to detect the brake drum, corrects the photographed image according to known dimensional information of the brake drum included in an elevator, and detects a circular arc showing a region of the brake lining from the corrected photographed image; and a measurement unit 15 which calculates the dimension of the brake lining based on a region of the brake lining that is detected from the photographed image by the processing unit.SELECTED DRAWING: Figure 2

    【課題】昇降機のブレーキライニングの寸法測定が撮影した画像から良好に行えるようにする。【解決手段】ブレーキドラムの周囲のブレーキライニングを撮影した撮影画像から、最大曲率を有する楕円形又は円形を認識することでブレーキドラムを検出すると共に、昇降機が備えるブレーキドラムの既知の寸法情報により撮影画像を補正し、補正した撮影画像からブレーキライニングの領域を示す円弧を検出する処理部13と、処理部が撮影画像から検出したブレーキライニングの領域に基づいて、ブレーキライニングの寸法を算出する測定部15とを備える。【選択図】図2
