Research Of Target Recognition Technology For Infrared Image

Guidance system is the most important part of modern high precision guided weapons. Having the characters of high sensitivity, strong anti-jamming capability and good concealment, infrared imaging guidance has become the main trend and direction for current development and study of precision guidance technologies.On the basis of image processing system of infrared seeker, this thesis has made particular studies on various aspects such as infrared characteristic of object, target recognition and target tracking.This paper introduced basic theories and characteristics of infrared imaging guiding, described the system scheme and hardware design in great detail, put forwarded a image processing algorithm of segmentation identification for an object. Compared with the traditional two-value target recognition algorithm, the new algorithm had the characters of easily understanding, simply using and fast computing speed. This paper also introduced three kinds of target recognition methods with rotation scale and translation in-variation.The emulation results on the hardware platform showed that the hardware run stably and was with strong anti-interference ability. The software programmed according to the algorithm could recognize the target accurately and quickly in real-time, which satisfied the design requirements.
