Modern digital cameras use sensor arrays that correspond to millions of pixels in the image. However, the single-pixel imaging (SPI) system captures images by a single-pixel detector without the need for a pixelated sensor to have spatial resolution. Research on SPI has attracted more and more attention from scholars. The SPI system provides a potential low-cost solution for sensing beyond the visible spectrum. Also, it is suitable for obtaining information in low light, high absorption, and backscattering conditions. This paper reviews the developments and performance of SPI, the research on static and dynamic objects, the methods of the real-time three-dimensional imaging and video. The potential applications of SPI are further explained in detail.

简要回顾使用单像素成像的2D和3D图像重建

现代数码相机使用的传感器阵列对应于图像中的数百万个像素。但是，单像素成像（SPI）系统通过单像素检测器捕获图像，而无需像素化传感器具有空间分辨率。对SPI的研究引起了越来越多的学者的关注。SPI系统提供了一种潜在的低成本解决方案，用于在可见光谱范围之外进行传感。而且，它适合在弱光，高吸收和反向散射条件下获取信息。本文综述了SPI的发展和性能，静态和动态对象的研究，实时三维成像和视频的方法。SPI的潜在应用将进一步详细说明。
