Abstract: Thermal infrared scanning image is a continuous picture of film baud which is different from multi-picture of the aerophotograph. In general, the aerophotograph has a pair of pictures which can be stereoscopic observation, topographical measurement and geometrical correction that can make image format map. But then, thermal infrared scanning image only just has two-dimension information. Especially, thermal infrared scanning image was obtained in night. For example, a small white point in the image will be a pond or a hill of carbonatite. The pond has higher thermal capacity so higher apparent temperature, but the hill of carbonatite has higher emissivity so higher apparent temperature. The pond and the hill both are small white point in the image.The author tries to solve the stereoscopic model of thermal infrared scanning image which can give clear and vivid vision in order to decrease the difficulty of interpretation. This result proves theoretically correct and indicates the possibility of obtaining a steroscopic imagery. It was arranged that each flight band has a 60% overlap with the next band in a test of aircraft thermal infrared scanning survey in the Karst region of the Guilin-Yangshuo of Guangxi Chuang Autonomous Eegion of China in November 1977.In this way, we have got stereoscopic pairs both of day and night imageries. This paper discusses:1) The geometreial characteristics of thermal infrared scanning images.2) The principle of thermal infrared scanning stereoscopic imagery pairs.3) A test and result of thermal infrared scanning stereoscopic imagery pairs.4) The topographical measurement and geometrical correction of thermal infrared scanning stereoscopic imagery pairs.
