| The early-warning to airborne raid-goal is mainly completed by radar. Along with the enemy interference method enhancement and "the hiding" technology unceasing development, the detection and track to raid-goal are developed to multi-wave bands synthesis direction including radar, infrared and visible light. The infrared target detection, tracking and measure system with the ability of invisibility, strong anti-disturb and whole-day observation, are increasingly welcomed by military. Because infrared original image nonuniformity and real-time target recognition methods are always restricted by hardware, the distance of infrared detection and recognition system can detected is greatly limited, and the reliability of system tracking is reduced too. In the development process of a certain radar photo-electricity theodolite measure system, aimed to the requirement of infrared target detection sub-system and technique difficulty in project practice, we studied the control of infrared camera, the nonuniformity adjustment, and finally used them in project. The system's work data show that our research is efficiency, and beyond the requirement of design guideline. This dissertation is divided into five chapters. First chapter has outlined the infrared detection technology military application domain, the topic origin and the research content. Second chapter introduced the infrared imagery technology base and the noise originates outside of infrared focal-plane array (IRFPA), as well as each kind of noise influence to the infrared image. From third to fifth chapter, it discussed the method of nonuniformity adjustment to infrared camera by using serial port. Finally, the practice effect of nonuniformity adjustment to infrared image is introduced. |
