Abstract

Abstract: To speed up single pixel imaging at a low cost, solutions are proposed on the hardware and algorithm, so that a single pixel imaging system with software and hardware cooperation is built. On algorithm, DQN-Hadamard single pixel imaging is proposed by introducing DQN algorithm into Hadamard single pixel imaging, to obtain the relatively optimal sampling sequence for specific target objects. On hardware, based on the high-speed and low-cost pattern projection scheme using LED array, ZYNQ 7020, which combines the characteristics of ARM and FPGA, is selected as the controller to build a Hadamard single pixel imaging system with ARM and FPGA cooperation. Finally, combined with the algorithm and hardware, the transplantation of DQN-Hadamard single pixel imaging to the built Hadamard single pixel imaging system is completed. The imaging results are detailed compared with the results of the single pixel imaging using adaptive zig-zag sampling. The imaging results show that the target object can be reconstructed at the sampling rate of 30%, which verifies the feasibility of low-cost single-pixel imaging with software and hardware cooperation.

Key words: single-pixel imaging, ZYNQ, DQN, low-cost, hardware and software coordination
