摘　　要：提出一种新型三维彩色光学数字成像系统。此系统利用投影结构光对现实世界中的物体进行数字化 ,同时得到对应的彩色纹理。详细介绍了系统的硬件设计和软件体系结构设计 ,得到物体彩色纹理的两种不同方法 :直接获取和从编码条纹中提取 ,给出了用该系统得到的实验结果并简单评价了系统的性能。此系统在反求工程、影视制作、三维游戏制作。A new type of 3 D digital imaging system is proposed. Using this system, the shape of an object can be digitized and the texture of this object can be obtained simultaneously. The hardware design and software framework design of the system are described in detail. Two methods to get the color texture of object are introduced. One is to extract from the coded fringe pattern; the other is directly to capture the texture of the object without fringe pattern. The 3 D digital image made on a human face as an experimental result is given. The system has great a potential in many industrial applications such as reverse engineering, film making, CAD/CAM, virtual reality, biomedical imaging, etc.
