Abstract

Cartosat-1 is stereo satellite launched in May 2005 for analysis of Indian terrain. Most effective application of cartosat-1 data is creation of Digital elevation models from stereo pair. Cartosat-1 operated in different modes like Normal Mode, Reverse Pitch Mode & Wide Mono-mode. Pitch bias plays significantly important role in detection of modes of cartosat-1. DEMs are generated for Pune area by using stereo images belonging to different modes of cartosat-1. The accuracy of generated data evaluated with the help of reference DEM available for Pune Area. Rational polynomial coefficients (RPC) used for Photogrammetry & DEM generation. Generated DEMs are compared by using different parameters like Standard deviation, Slope, Aspect. By combining both modes we tried to remove blunders as well as errors occurred during DEM generation. Fusion of Cartosat-1 DEM with reference DEM also carried out. DEMs generated from above stereo pairs are of type Relative DEMs i. e DEMs without GCPs.

基于数字高程模型融合的cartosat-1不同模式分析

Cartosat-1是一颗立体卫星，于2005年5月发射，用于分析印度地形。cartosat-1数据最有效的应用是从立体对中生成数字高程模型。Cartosat-1在正常模式，反向音调模式和宽单模等不同模式下操作。基音偏差在cartosat-1模态检测中起着重要的作用。使用属于cartosat-1不同模式的立体图像生成浦那地区的dem。利用浦那地区现有的参考DEM对生成数据的精度进行评价。有理多项式系数(RPC)用于摄影测量和DEM生成。生成的dem通过使用不同的参数进行比较，如标准差、斜率、Aspect。通过结合这两种模式，我们试图消除在DEM生成过程中出现的错误和错误。同时进行了Cartosat-1 DEM与参考DEM的融合。由上述立体对生成的dem为相对dem，即不含gcp的dem。
