Development of 3D measuring system and applications to construction joints of concrete and to free vibration analysis of twisted cylindrical panel

In order to measure the surface roughness three-dimensionally, noncontact and portable 3D measuring system is developed. This system is composed of the two CCD cameras and laser beam, and is based on three types measure method, i.e. stereo-photogrammetry, spot-laser and slit-laser photogrammetry. As...

Zusammenfassung:In order to measure the surface roughness three-dimensionally, noncontact and portable 3D measuring system is developed. This system is composed of the two CCD cameras and laser beam, and is based on three types measure method, i.e. stereo-photogrammetry, spot-laser and slit-laser photogrammetry. As the applications of 3D measurement, the problem of construc tion joints of concrete and free vibration analysis for twisted thin cylindrical shell panels are investigated.
