An Efficient Imaging Strategy for Single Pixel Camera

Article Preview

Abstract:

Single pixel camera is a new imaging device that develops from the ghost imaging and compressive sensing theory. For high resolution remote sensing imaging with large amount of data, the process of measurement and reconstruction is time-consuming, which limits its application to remote sensing area. Based on the analysis of the configuration of the single pixel camera, an efficient imaging strategy through combining different numbers of micro mirrors was proposed. Simulation experiment was carried out for the scene consisting of a ship in the ocean. Three types of images, in low, middle and high resolution, are constructed respectively by the control of DMD working area and the strategy to combining DMD mirrors. The reconstructed images reached the application requirements at very low measurement and reconstruction time cost. The effectiveness and practicality of this strategy could be applied to other compressive sensing imaging devices.
