摘要
多源影象数字复合是扩充遥感影象信息的有效手段。本文以八大公山自然保护区美国陆地卫星ＴＭ影象与１∶５０，０００地形图等高线进行复合，对几何配准精度进行了试验研究。试验表明：用二元三次多项式对ＴＭ影象进行几何精校正，用二元三次多项式对等高线图进行扫描畸变纠正后，对于高山地区的遥感影象，具有较好的几何配准精度，能够满足分类判读的需要。
The Multi-source image digital composition is an available way for increasing the information of remote sensing image.The experiment about geometric registration of Landsat TM image of Badagong Mountain Nature Reserve and the 150000 scale topographic map is given in this paper.The result shows that in the high mountain area,using binary cubic polynomial correction for the TM image and binary quadric polynomial correction for the TM image and binary quadric polynomial correction for the scanning contour map,the precision of geometric correction is good,and the accuracy of geometric registration is sufficient for visual interpretation.\;
