THREE-DIMENSIONAL MEASUREMENT SYSTEM
PROBLEM TO BE SOLVED: To provide a device with which it is possible to measure a change of the shape of an object with high accuracy from a safe place away from the object irrespective of an environment around the object in a district where there is a risk of disaster occurrence or a disaster has already occurred.SOLUTION: Provided is a three-dimensional measurement system for measuring the shape of an object, including: (1) an irradiation device for irradiating the object with a blue pattern light; (2) a photographing device for photographing reflected light from the object; (3) an image processing device for processing an image obtained by the photographing device and storing processed data, the image processing device capable of obtaining an image of the object with the effect of background light removed and measuring the depth of the object from the image of the object with the effect of background light removed.SELECTED DRAWING: Figure 14
【課題】災害が発生する危険がある区域又は災害が既に発生している区域において、対象物の形状の変化を、対象物を取り巻く環境によらずに、対象物から離れた安全な場所から、高精度で計測することができる装置を提供する。【解決手段】対象物の形状を計測するための３次元計測システムであって、（１）対象物に青色のパターン光を照射するための照射装置、（２）対象物からの反射光を撮影するための撮影装置、（３）該撮影装置において得た画像を処理してデータを保存するための画像処理装置であって、背景光の影響を取り除いた対象物の画像を得、背景光の影響を取り除いた対象物の画像から対象物の奥行を測定することができる画像処理装置、を包含するシステム。【選択図】図１４
