摘要
为了有效地更新数字地图，作者设计了＂伪立体法＂，用于地形起伏大且没有ＤＥＭ来改正大的投影差的地区。本文介绍了所设计方法的基本思想和实验结果。
The pseudo--stereo method is developed to provide an effective tool for map revision. The method is designed for the case when significant relief displacements exist in the image and no DEM is available to correct them.The imags,however,has to provide a stereoscopic coverage.The basic idea of this method and the software developed are described then the testresults and discussion of the results are given.
