摘要:

正射遥感影像是当前3S工程应用最广泛、最基础的影像产品。然而目前大多数正射遥感影像的制作中,由于采用不完备的地面模型,传统的正射影像不可避免地出现地物错位和遮挡等现象,严重影响了工程质量与制图精度。探讨利用数字建筑物模型(DBM)和数字高程模型(DEM)进行影像真正射纠正的原理和制作工艺,以及真正射影像制作过程中存在的问题及解决方法。

关键词: 真正射纠正数字建筑物模型(DBM)数字高程模型(DEM)通视分析    
Abstract:

Orthophoto imagery has been widely used in the remote sensing study.However,due to the use of incomplete terrain model,phenomena such as surface features dislocation and block inevitably occurred in the traditional orthophoto has seriously affected the quality of the project and mapping accuracy.This study discussed the principle of using DBM (Digital Building Models) and DEM (Digital Elevation Model) for the true orthorectified imagery and the key technologies of workmanship in producing the true orthorectified remote sensing image.In theory,the True Orthoimage map,produced by DSM and DBM,detected and compensated by block area,could completely solve all of problems of traditional Orthoimage map.It is the best choose of detecting changes,collecting surface features and producing three-dimensional landscape.The advantage is obvious.But,relative to Simple treatments of traditional Orthoimage map,notable feature of Ortho-corrected map is enormous amount of data operations.On the other hand,difficulties and costs to get DBM/DSM is still expensive,so the using of the True Orthoimage map is limited in city.
