Determination of temperature contrast of cooperative target and background

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.
