摘要
为了降低对红外热像仪最小可分辨温差（MRTD）检测的成本，对使用者一级的MRTD 检测方法进行了研究，提出了一种基于FLIR92 模型和BP 神经网络的MRTD 检测方法。该方法在兼顾检测精度的基础上，对检测条件和检测人员的要求大大降低，同时降低了检测成本，对降低红外热像仪的使用和维护成本具有重要意义。
Abstract
For reducing the cost of testing the minimum resolvable temperature difference (MRTD) of the infrared thermal imaging system，a MRTD testing-method on user-level had been researched and a method based on FLIR92 model and BP neural net work had been put forward. This method reduces the requirement of experiment conditions and testing-man and also has a sufficient testing-precision. It has a important meaning on using and maintenance of the thermal imaging system.
