【摘要】 地面控制点的精度和分布很大程度上决定了Landsat MSS图像几何校正的精度，然而选取高质量的控制点往往比较困难。在地形起伏较大的山地，根据由DTM导出的二值图像和MSS图像阈值分割得到的二值图像之间的相关配准，可以自动选取地面控制点。试验表明，这些控制点用于图像几何校正，能得到较好的校正精度。更多还原

【Abstract】 Precise geometric correction of Landsat MSS imagery is largely dependent on theaccuracy and distribution of GCP. However. it is frequently difficult to select the GCPwhich is of high quality. By means of digital correlation of the binary image obtainedfrom DTM with the binary image obtained by segmentation of MSS imagery. relativelyprecise GCPs can be automatically selected in areas of rugged terrain.更多还原
