Research On Processing Electronics Key Technique Of The High Performance Staring Thermal Imaging System

Along with development of the IR technique, staring infrared imaging technique hasbecome one of the most advantage and the most potential arisen technique around theworld today. Due to the technique blockade of foreign developed country and the researchon infrared imaging lag behind foreign developed country, the theories research level anddevice's manufacture techniques fall behind foreign developed country. So the IRFPA andIRFPA thermal imaging system in China fall behind foreign developed country. Researchon the IRFPA detector and high performance IRFPA thermal imaging system is veryimportant for the national defense and civil economic development.New theoretic models on processing electronics theory of the IRFPA imagingsystem are proposed in this paper through the deep research on the imaging mechanism ofIRFPA and inherent disadvantages of IRFPA. New theoretic models here includes:blind-pixel theoretic model based on multiply temperature match, binary non-linearnon-uniformity theoretic model based on objects and scene. 3-D random noise theoreticmodel of IRPFA thermal imaging system, 2-D histogram's statistical characterizationtheoretic model of IRFPA imaging had been reseached and analyzed in this paper. Basedon these advanced theoretic models here, processing electronics theory and technologyhave been formed on this paper. In order to prove these new advanced theoretic modelshere, test system for IRFPA key factors of multiply operation modes based on VirtualInstrument has been built. Large numbers of data obtained from the test system haveproved the correctness of the blind-pixel theoretic model and non-uniformity theoreticmodel advanced here. To speed up the design of new IRFPA imaging system, dynamicsimulation system for IRFPA imaging processing based on Virtual Instrument, test systemand evaluation system for IRFPA thermal imaging system also based on Virtual Instrumenthave been built. A complete architecture of processing electronics theory, test, simulationand evaluation for IRFPA has been finished. Based on the work above, research on imageprocessing technology for IRFPA imaging has been done. Many new algorithms arepresented here, including: algorithm of self-adaptive blind-pixel detection based onmultiply temperature match, algorithm of binary non-linear non-uniformity correctionbased on objects and scene temperature, algorithm of self-adaptive output window forIRFPA imaging based on gray-level redundancy, An Image Sharpening Algorithm Basedon the Fuzzy Theory. Lots of experiments and simulation have been done according to thealgorithms presented here. Algorithms presented here have been proved that all of them are of great effective and real time through the dynamic real time simulation. Based on theresearch on IRFPA imaging processing and results of the dynamic simulation, modularizedreal time image processing instruments of utility have been finished. These instrumentsprove that the image processing technologies advanced here are very effective and realtime. At the same time the foundation of mass production of IRFPA and high qualityIRFPA thermal imaging system have been built.
