摘　　要：提出一种利用光学导管在受限空间内进行三维形貌测量的方法。由多块反射镜构成的光学导管可以将投影系统在空间外产生的条纹图像投射到空间内表面;同时也可以将空间内采集到的图像传送到空间外并被CCD接收。避免了由于空间制约引起的阴影和遮挡,实现了在受限空间内部进行三维测量。实验结果表明了该方法有效可行。A three-dimensional （3D） shape measurement method for confined space using an optical tube is proposed. Considering small cross-sectional area and high reflectivity, a optical tube is designed for image transmission. With the optical tube, fringe patterns can be easily projected onto internal surface from external space. The collected images transferred from interior space to external space are recorded by CCD. Accordingly, shade and occlusion caused by the limitation of measurement space are avoided and 3D shape measurement for internal surface of confined space is realized. Experimental results show feasibility and validity.
