摘　　要：非视域成像是一种新型针对视线外目标的计算成像技术,它以时间飞行探测技术为基础,通过探测被隐藏在视域之外的物体反射回来的光子利用重建算法来重建隐藏物体的像,在自动驾驶、灾难救援、医学成像和军事反恐等方面有着广阔的应用前景。首先介绍了近年来发展起来的主动和被动非视域成像系统的研究现状,从非视域成像系统的成像装置、分辨率和重建算法等几个方面分析各自的特点和发展趋势。最后,还讨论了非视域成像技术在实际场景应用中所需要解决的一些关键问题,并展望了非视域成像技术的未来发展方向。Non-line-of-sight imaging is a new type of computational imaging technology for out-of-sight areas which is based on time-of-flight detection technology. The photons reflected from hidden objects are detected by a detector and reconstruction algorithms are used to reconstruct their images. It has great application value in autonomous driving, disaster rescue, medical imaging and military counter-terrorism. In this paper, the research status of active and passive non-line-of-sight imaging systems developed in recent years is firstly introduced, and its characteristics and development trend are analyzed from several aspects, such as imaging devices, resolution, and reconstruction algorithms. At last, some key problems that need to be solved in the practical scene applications of the non-line-of-sight imaging are also discussed, and the future development direction is prospected.
