摘要
以西藏自治区桑日县为例,在PCI图像处理软件中,将中巴地球资源卫星(CBERS)采集的遥感影像数据经过预处理后叠加到格网DEM上形成水平三维场景。操作中通过调整观察参数,达到理想的三维可视化效果。着重介绍了FLY!模块中三维飞行的实现步骤,对用户运用PCI软件完成三维可视化起到指导性作用。
Taking Sangri County,Tibet as an example,the processed remote sensing image which was acquired by CBERS,is added to the Grid DEM with PCI image processing software so that the three-dimensional（3D） level scene is formed.By adjusting the parameters of observation in operation,the ideal effect of 3D perspective could be achieved.The implementation steps of 3D fly-through with the FLY! Module is introduced in particular.The whole course plays a guiding role in the completion process of 3D perspective by PCI.
