中文摘要：

主动三维视觉传感技术主要有飞行时间法、点结构光扫描法、线结构光扫描法和编码面结构光法、莫尔法、相位测量轮廓术、傅里叶变换轮廓术等。介绍了上述各种技术的基本原理和优缺点。提出了一种新的技术，即单幅二维图像不标定自适应三维场景重构技术，给出了它的原理并讨论了其特点。

英文摘要：

3-D active vision sensing technique is mainly involved in time-of-flight method,point structured light scanning, linear structured light scanning and space encoding structured light method, Moire contouring, phase measuring profilometry, Fourier transform profilometry, etc. The basic principle and characteristics of all these method are introduced. A new method,i. e. , the 3-D shape from a single image and non-calibration technique is proposed. Its principle is given, and its features are discussed.
