For　uncooled　LWIR　system　function　limitations　and　lack　of　real-time　image　processing　problems.　The　design　scheme　of　high　performance　uncooled　LWIR　image　processing　system　based　on　UAV　system　platform　is　proposed.　The　solution　uses　TI＇s　TMS320C6657　DSP　and　Altera＇s　EP3C25F324　FPGA　processor　as　the　system　computing　core,　makes　the　long　wave　infrared　image　acquisition,　FPGA　image　preprocessing,　DSP　image　processing　into　one.　And　designed　a　set　of　systems　in　line　with　the　external　needs　of　the　communication　program.
