摘要:
针对异型传像光纤束成像的算法结构,介绍了一种以TI公司高性能DSP(TMS320DM642)和Xilinx公司150万门级FPGA(XC3S1500)为核心处理器的超分辨率成像系统。在该系统中,作为系统核心的DSP承担目标图像合成算法,而FPGA则负责如图像格式转换等预处理工作。通过合理分配DSP和FPGA的处理任务,本系统充分发挥了FPGA硬件实现的快速性和DSP软件实现的灵活性。实验测试表明,该成像系统满足实时性要求,易于维护和升级,具备较强的通用性。
Abstract:
A frame work of a super-resolution imaging system which adopts the TI’s high performance DSP TMS320DM642 and Xilinx’s FPGA with 1500000 gates as the core is presented in this paper for the special structure of imaging algorithm with the non-conventional image-carrying fiber bundles. In this system, the DM642 is responsible for the synthesis algorithm of the target image as the core unit of the system; While the image pre-processing like image format conversion is implemented in the FPGA. By the rational allocation of the DSP and FPGA’s processing tasks, we can give full play to their respective advantage. The experimental result shows that the imaging system meets the real time requirement. It is easy to maintain and upgrade with a strong commonality.
