摘　　要：为在较低成本下解决单像素成像速度问题,从硬件和算法两个层面提出解决方案,搭建软硬件协同的单像素成像体系。算法层面在Hadamard单像素成像中引入DQN算法,提出DQN-Hadamard单像素成像,获得对特定目标物体的相对最优采样顺序。硬件层面基于LED阵列的高速低成本基底图案投射方案,选择ARM与FPGA特性结合的ZYNQ 7020作为主控,搭建ARM与FPGA协同的Hadamard单像素成像系统。最后结合算法与硬件,完成DQN-Hadamard单像素成像在ARM与FPGA协同的Hadamard单像素成像系统的移植,并与自适应斜Z字形采样单像素成像做了详细比较。成像结果显示,所提方案在30%的采样率下即可重建目标物体图像,验证了低成本软硬件协同单像素成像的可行性。To speed up single-pixel imaging at a low cost,solutions are proposed from both hardware and algorithm aspects,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 the cooperation of ARM and FPGA.Finally,combining the algorithm and hardware,the transplantation of DQN-Hadamard single-pixel imaging to the built Hadamard single-pixel imaging system is completed,and then DQN-Hadamard single-pixel imaging system is compared with the single-pixel imaging system using adaptive zig-zag sampling in detail.The imaging results show that as for the proposed imaging system,the target object can be reconstructed at the sampling rate of 30%,so that the feasibility of low-cost single-pixel imaging with software and hardware cooperation is verified.
