摘要
近年来偏振三维成像技术因具有精度高、作用距离远和受杂散光影响小等特点得以蓬勃发展,但利用目标反射光偏振特性进行法向量精确求解的问题一直没有真正得到解决,成为制约该技术发展的瓶颈。此外,由于目标表面镜面反射光与漫反射光间的相互干扰,造成高精度偏振三维成像实现困难。该综述介绍了偏振三维成像物理机理、目标表面出射光偏振特性,以及偏振三维成像研究进展。最后总结了目前偏振三维成像面临的问题和未来的发展方向。
In recent years,there is an increasing interest in polarization 3D imaging technology,due to the advantages of high accuracy,long imaging distance and immune to the stray light polarization.However,the accurate acquisition of normal vector information of the surface is quite difficult by utilizing the reflected light characteristics of the surface,which constitutes an obstacle to the development of the technology.The mixture of specular reflected light and diffuse reflected light is the main factor for deteriorating the performances of polarization 3D imaging.In this review,the basic principle of polarization 3D imaging technology and polarization characteristics of reflected light were introduced.Meanwhile,the development of polarization 3D imaging technology was also reviewed.Finally,the problems and the future improvement in polarization 3D imaging are summarized and prospected.
