Based on the principles of temperature measurement using infrared thermography and the theory of thermal imaging, a uncooled IR FPA thermometry system is designed. In this system, the mathematic model of infrared thermometry calculation is established, and appropriate formulas for error analysis and calculation are obtained. The algorithm calculating the apparent emissivity of target surface is also put forward. In addition, several concrete algorithms about non-uniformity correction of thermal imaging arc introduced and comparison of these algorithms is made in the view of practice. Based on research of thermal image, two kinds of image enhancement algorithms are applied. One is gray newly-arranging enhancement algorithm which based on histogram equalization, the other is Pseudo-color enhancement. In this dissertation, system construction and system technological process are designed, and corresponding software is designed. Some experimentations are developed and corresponding conclusions are gained.
