This study focused on three dimensional measuring system and its application. A non-contact and portable three dimensional measuring system has been developed for measuring the three dimensional profiles. 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.This 3D measuring system have been performed the following problems.(a) Construction joints of concreteThe roughness of 9 types concrete surface were measured three dimensionally, and slant shear tests were carried out, and the relationship between the roughness of concrete surface and the bond strength was investigated.(b) Twisted thin shellsThe surface of twisted thin shells were measured three dimensionally, and free vibrations of finite element analysis are carried out by using measured 3D data. Eigen values and modes were compared with the results by laser holograph experiment.(c) The wrinkling of tensioned membrane structures were measured. The performance of the present system is verified by comparing the results with those obtained by the other methods.

本课题主要研究三维测量系统及其应用。研制了一种非接触、便携式的三维轮廓测量系统。该系统由两台CCD摄像机和激光束组成，基于立体摄影测量、点激光摄影测量和狭缝激光摄影测量三种测量方法，完成了以下几个方面的工作。(a)混凝土施工缝通过对9种混凝土表面粗糙度的三维测量和斜剪试验，研究了混凝土表面粗糙度与粘结强度的关系。(b)对扭转薄壳的表面进行了三维测量，并利用三维测量数据进行了有限元自由振动分析。将本征值和模式与激光全息实验结果进行了比较。(c)对张拉膜结构进行了振动测试。通过与其他方法的结果进行比较，验证了本系统的性能。
