A new real-time processing system for the IRFPA imaging signal based on DSP&FPGA

摘要

The principle, configuration and special features of a new high-precision real-time signal processing system for Infrared Focal Plane Arrays is presented in this note. A structure based on DSP&FPGA is adopted in the system. The FPGA implements the system timing control and the low level algorithms. The DSP performs the high-level algorithms, such as nonuniformity correction for the IRFPA. Nonuniformity correction and image enhancement and display algorithm, the two crucial algorithms for IR imaging signal processing, are also discussed in this note. The experiments on real IR imaging sequences demonstrate that the system is suitable for the real-time high-speed IR imaging system with high quality and high precision. (c) 2004 Elsevier B.V.
