GPS/INS (Global Positioning System / Inertial Navigation System) brings
possibility of relaxing the demand for aerial triangulation in stereo model
construction and rectification. In this thesis a differential rectification algorithm is
programmed with Matlab software for aerial frame camera images. This program
is tested using exterior orientation parameters obtained by GPS/INS and images
are ortho-rectified. Ground Control Points (GCP) are measured in the orthorectified
images and compared with other rectification methods according to
RMSE and mean error.
Besides, direct georeferencing accuracy is investigated by using GPS/INS data.
Therefore, stereo models and ortho-images are constructed by using exterior
orientation parameters obtained with both aerial triangulation and GPS/INS
integration. GCPs are measured in both stereo models and ortho-images,
compared with respect to their RMSE and mean error. In order to determine
Digital Elevation Model (DEM) effect in ortho-rectification, different DEM data
are used and the results are compared.
