意义和方法以往热红外图像只用于定性研究地面景物。现在更多要求定量确定地面或海面的温度。确定地面和海面的温度可以更好地分析土地状态、矿藏分布和鱼群动向等,因此温度数据是资源开发的重要依据。红外波段优于其它波段,因为它能直接反映地面温度,并可进行日夜监视。所以近年来世界各国对红外图像的研究极为重视。从地面或海面发射到卫星上的红外波段幅射能量,通过大气层时部份能量被大气中的水
Significance and methods In the past, thermal infrared images were only used to qualitatively study ground objects. Now more require quantitative determination of the surface or sea temperature. Determine the temperature of the ground and the sea surface can better analyze the state of land, mineral distribution and fish movement, etc. Therefore, temperature data is an important basis for resource development. The infrared band is superior to the other bands because it directly reflects the ground temperature and can be monitored day and night. Therefore, in recent years, all countries in the world attach great importance to the research of infrared images. From the ground or the surface of the sea launched into the satellite infrared radiation energy, through the atmosphere when part of the energy by the water in the atmosphere
