结构光三维成像技术研究进展

A review of structural light 3D imaging technology

结构光三维成像技术作为一种主动非接触式成像技术,不但可以保存物体的三维空间信息,而且可以完整地复现物体的空间三维图像.该技术在高精度、高分辨率复原物体轮廓方面有着重要的意义.该文综述了基于不同结构光的3种成像方法,重点介绍了基于面结构光的成像方法及其关键技术,最后对结构光三维成像技术进行了总结和展望.

As an active non-contact imaging technology,structured light 3D imaging technology can be used not only preserve 3D spatial information of objects,but also to reconstruct the 3D spatial image of objects completely,which had a great significance in the restoration of object contour with high precision and resolution.In this paper,three imaging methods based on different structured light are introduced,and the imaging methods based on surface structural light and its key technologies applied were mainly introduced.Finally,3D imaging technology of structural light was summarized and prospected.
