Abstract

　計測対象に投影された、位置に応じて輝度が変化する縞状の光パタンを解析することによって、計測対象（１２）の三次元形状を計測する三次元形状計測装置（１０）であって、計測対象（１２）が配置され、上記光パタンが投影される計測面（５２）を備えた移動ユニット（１１）と、上記光パタンを計測対象（１２）および計測面（５２）に投影する投光ユニット（１３）と、上記光パタンを画像として読み取る撮像ユニット（１５）とを備え、撮像ユニット（１５）は、計測面（５２）上のある位置Ｗ０からレンズ（３３）までを結んだ線分Ｌ０Ｗ０と計測面（５２）の垂線との間の角度をθｐ、位置Ｗ０から撮像ユニット（１５）までを結んだ線分と上記計測面の垂線との間の角度をθｃとする場合に、計測対象となる計測面（５２）の領域内において、ｔａｎθｃ＋ｔａｎθｐを一定に保つように上記光パタンの縞を投影している。これにより、計測精度を向上させた三次形状元計測装置を実現する。
