红外热成像系统温度漂移补偿算法研究
Study on temperature drift compensation of infrared thermal imaging system
摘要
Abstract
Influenced by environmental temperature, infrared focal plane arrays (IRFPA) response output has obvious temperature drift after working for a long time, which causes larger temperature measurement error of infrared thermal imaging system(IT IS). Therefore, a temperature drift compensation algorithm of IT IS is presented. The algorithm establishes a temperature compensable model for IRFPA response output drift with the environmental temperature, which can correct the drift value of every detector response output. With this compensation algorithm, some infrared object temperature display experiments in IT IS have been done. The experimental results show that the algorithm can effectively reduce temperature drift caused by the environmental temperature, and temperature measuring accuracy of IT IS can be greatly improved.关键词
