More Information
Summary:The invention relates to a DSM data processing method. The method comprises the steps of calculating overlapping regions of adjacent DSM data; according to elevation information of the overlapping regions, determining features of the regions and difference between the regions, and then according to the features and the difference, performing terrain matching; and fusing DSM data subjected to the terrain matching. The seamless connection of the DSM data is realized. 本发明涉及种DSM数据处理方法，包括：计算相邻DSM数据的重叠区域；根据重叠区域的高程信息确定各个区域的特征和各个区域之间的差异，然后根据所述特征和差异进行地形匹配；将经过地形匹配后的DSM数据进行融合。本发明实现了DSM数据的无缝衔接。
