Design method of ARM based infrared camouflage target recognition system

摘要

With the advantages of stealthiness, all weather effectiveness, visible target recognition and long affect distance, infrared thermal imaging system play important role in scouting, aiming and tracking. In order to eliminate influences of thermal camouflage to traditional intensity infrared thermal imaging system, we proposed design method of ARM based infrared camouflage target recognition system. Considering the measurement of Stokes parameters, we analyzed design method of polarized image acquisition module, designed ARM core board and its data connection with other devices, adopted LCD to display polarization image computed out by ARM. We also studied embedded Linux platform and polarized image processing program based on this platform, finally actualized the design method of ARM based infrared camouflage target recognition system. Results of our experiment show that data stream can be successfully transmitted between modules of the system and the platform we used is fast enough to run polarized image processing program. It's an effective method of using ARM to actualize infrared camouflage target recognition system.
