發(fā)布時間:2018-08-26 11:24
【摘要】:傳統(tǒng)的光學成像技術(shù)是通過探測器對視線區(qū)域內(nèi)的場景成像,而非視域成像技術(shù)是對觀察者視線之外的區(qū)域進行成像,它通過一個中介面,對被其他物體遮擋住的隱藏物體成像(如拐角處、煙霧后等),是近年來剛發(fā)展起來的一種新的光學探測技術(shù)。該項技術(shù)對于反恐、災難救援、城市交通等都有重要意義。本文針對國內(nèi)外非視域成像系統(tǒng)的特點進行總結(jié)分析,根據(jù)成像系統(tǒng)的成像機制不同,將目前非視域成像系統(tǒng)分為4種主要類型,分析其應用的優(yōu)缺點,并從成像裝置、成像分辨率和重建算法幾個方面分析其研究趨勢。
[Abstract]:The traditional optical imaging technique is to image the scene in the line of sight area through the detector, but not the field of view imaging technology is to image the area outside the sight of the observer, it passes through an intermediary plane. Imaging of hidden objects (such as corners, smog, etc.), which is obscured by other objects, is a new optical detection technique developed in recent years. This technology has important significance for anti-terrorism, disaster rescue, urban transportation and so on. In this paper, we summarize and analyze the characteristics of non-visual imaging system at home and abroad. According to the different imaging mechanism of imaging system, we divide the current non-visual imaging system into four main types, analyze the advantages and disadvantages of its application, and analyze the advantages and disadvantages of the imaging device. The imaging resolution and reconstruction algorithm are analyzed in this paper.
