When single-pixel imaging (SPI) is applied to imaging the dynamic object, severe motion blur in the restored image tends to appear. Researchers in China used a small amount of information detected by the single-pixel detector to locate and track the moving targets. With the increase of detection information over time, imaging of fast-moving objects and motion blur correction were realized synchronously. The technology fully exploits the characteristics of single-pixel detection and realizes rapid positioning, clear imaging, and recognition of fast-moving targets according to the characteristics of the system’s detection information data stream. The proposed technology roadmaps “tracking before imaging” subverts the time-sequence relationship of imaging before tracking in the traditional technical method…read more.
