20 May 2011Real-time georeferencing for an airborne hyperspectral imaging system
The paper describes the georeferencing part of an airborne hyperspectral imaging system based on pushbroom scanning.
Using ray-tracing methods from computer graphics and a highly efficient representation of the digital elevation model
(DEM), georeferencing of high resolution pushbroom images runs in real time by a large margin. By adapting the
georeferencing to match the DEM resolution, the camera field of view and the flight altitude, the method has potential to
provide real time georeferencing, even for HD video on a high resolution DEM when a graphics processing unit (GPU)
is used for processing.
