航空热红外遥感在探测石油管道中的应用

本文论证了热红外遥感探测石油管道的物理依据,并以野外实际测温资料讨论了探测管道的前提条件,同时分析了可能出现的干扰因素。从成像季节、成像时间、飞行高度和温度范围选择等方面讨论了最佳成像条件的选择,从当地条件出发,选择12月中旬,夜间前半夜成像取得了成功,经过图像处理与图像解译,建立了解译标志,编制了管道解译图,共发现管道364条,同时修改了原档案中错误资料多处,取得了良好的应用效果。

USING AIRBORNE THERMAL INFRARED REMOTE SENSING TECHNIQUES TO DETECT UNDERGROUND OIL PIPELINES

The authors discuss the principle and conditions of using airborne thermal infrared remote sensing techniques to detect underground oil pipelines. They also analyse the factors, such as the season, time, flying altitude and surface temperature, which affect the results. Data obtained during the first half of the night in the middle of December is judged to be most reliable. 364 subsurface pipelines were located using such data.
