摘　　要：在对武器装备中的红外系统进行靶场测试时,需要确定合作目标与背景的温度对比度,以作为测量基准。以测温热像仪摄取的图像为基本信息,基于目标与背景温度对比度的定义,参考常规检测和选取方法,结合合作目标的特点编制了确定温度对比度的软件,得出温度对比度的具体数值。通过实验测试,分析了不同选取方法对温度对比度的影响,对靶场测试等实际应用有参考价值,也为进一步建立各参数与温度对比度之间的关系模型提供了基础。While testing IR system of weapons equipment in firing range,it is need to determine the temperature contrast of cooperative target and background to be the benchmarks of measurement.Based on the definition of the temperature contrast of cooperative target and background, the images photographed by thermometric thermal image were regarded as the fundamental information, and the conventional detection and selection methods were refered to,and the characteristics of cooperative target were combined to develop the measuring software of temperature contrast,then the concrete value could be obtained.During the process of detection,effects of different selecting method on temperature contrast were analyzed, which had reference value for the parctical application such as firing range test,meanwhile ,it is a previous research to build the relationship between the parameters and temperature contrast of cooperative target and background.
