投計測物体上へ変形量を表示するための3D計測プロジェクションマッピングシステムの開発

抄録

In this study, a 3D measurement projection mapping system for displaying displacement distribution on a measured object using a grating projection method is developed. A grating projection method is often used as a high accurate 3D shape measurement method. It is also possible to apply the 3D shape measurement system to measure a wide and smooth curved surface such as a sheet metal processing. In this case, operators take much effort to recognize the spatial coordinates of some problem from the measured result displayed on a monitor. Therefore, authors have developed a rapid projection mapping method for the measured 3D shape and displacement distribution of a specimen. The developed system was applied to a 3D measurement of a deformed plate. The architecture and the experimental results are shown.
