摘要
传统的光学成像技术是通过探测器对视线区域内的场景成像, 而非视域成像技术是对观察者视线之外的区域进行成像, 它通过一个中介面, 对被其他物体遮挡住的隐藏物体成像(如拐角处、烟雾后等), 是近年来刚发展起来的一种新的光学探测技术。该项技术对于反恐、灾难救援、城市交通等都有重要意义。本文针对国内外非视域成像系统的特点进行总结分析, 根据成像系统的成像机制不同, 将目前非视域成像系统分为 4种主要类型, 分析其应用的优缺点, 并从成像装置、成像分辨率和重建算法几个方面分析其研究趋势。
Abstract
The non-line-of-sight vision imaging technology is different from the traditional optical imaging technology, which can go through an intermediary and imaging hidden objects (such as around the corner, behind the smoke, etc.)which are blocked by other objects. The non-line-of-sight vision imaging technology is a kind of newly developed technologies in recent years, which can detect the areas outside the sight of observer. The technology has important significances for counterterrorism, disaster relief, city traffic and so on. The paper summarized and analyzed the characteristics of the non-line-of-sight vision imaging system at home and abroad according to the imaging mechanism of the system. The imaging system can be divided into four main types, then the advantages and disadvantages in application of which were analyzed. And the development trend of imaging device, imaging resolution and reconstruction algorithm were also analyzed.
