[Abstract]:In recent years, with the combination of infrared detection technology and target recognition and tracking technology, infrared detection system is developing towards high resolution, high real-time and intelligent. There is an urgent need for a simulation system to simulate various infrared scenes in the laboratory to evaluate the detection effect of the infrared detection system and to test the effect of the target recognition and tracking algorithm in order to reduce the number of field experiments. This paper first introduces the dynamic infrared scene semi-physical simulation system and infrared scene projection devices at home and abroad. Then the design scheme of the driving system in the dynamic infrared scene simulation system based on MOS resistor array is given. The design of each module of the hardware circuit of the MOS resistor array driving system is introduced in detail. The problem of synchronizing 32 DAC outputs across clock domain and asynchronous clock signal is solved. Combined with the software flow chart of MOS resistor array drive system, the software design process of MOS resistor array data processing and sending and environment monitoring is introduced. The software architecture of the automatic close-loop environment monitoring system is given. The hardware modules and software functions of the MOS resistance array drive system are tested. Finally, the MOS resistor array driving system is docked with the MOS resistor array module, and the dynamic infrared scene projection test is carried out, and the relationship between the simulated temperature of the MOS resistor array and the control voltage is measured.
