Design Of High Performance Class Ⅰ Thermal Imager And Research Of Infrared Image Processing

There're many image defects in Class I thermal imager because of problems in design and machining , which also leads to inconvenient in assembly and debugging. After deep analysis of system structure and circuit design, we redesigned all of circuits of the thermal imager. With the hi-speed parallel processing ability of FPGA and the event-intensive controlling ability of MCU, we improve image quality effectively, eliminate the image defects and by adopting human-machine dialog mode, make the way of debugging and controlling more intellectualized, and shorten the time of debugging greatly. To gets higher image quality in future thermal imagers, the paper also discusses several image processing methods, and analyzes several different algorithms, evaluates their software and hardware overheads, approaches reasonable way of realization, and gets some valuable results. To simulate and emulate the image processing algorithms in software and hardware, the universal image processing platforms of software and hardware have been built. As a result, the realization process of infrared image processing is decomposed to serials of subprocesses including algorithms research, software simulation, hardware emulation, and transfer to target system, thus reduces the difficult of development, lessens the risk of investment, speeds the development, and provides a good basis to future works.
