Image Processing Solutions with Pictovera® Oblique
Special acquisition techniques also require special processing requirements, an aspect that was fully integrated and implemented from the ground up in the very creation of Dat’Air. The image processing engine applied to Dat’Air acquired photography is a software suite developed by the industry-renowned Stellacore Solutions, LLC. As part of the Dat’Air group of companies they specialize in providing solutions for achieving extreme fidelity results from multi-sensor payloads such as MIDAS systems. The Stellacore software is currently used to process over 18 million oblique frame images per year.
The Dat’Air Standard High Fidelity Mapping Product
The standard high fidelity product provided by DAT’AIR is five views (1-nadir (down) and 4-oblique (back, forward, left, and right at 45 degree off nadir)) 8-bit JPEG imagery with adjusted EO and calibrated sensor model information. The standard product achieves precision to 1 pixel or better and relative local accuracy to 1.5x GSD 2D/ 2x GSD 3D or better simultaneously across all directions. The standard product exceeds most high fidelity expectations. However, additional options are available which further exceed high fidelity expectations and provide greater return on investment.
Contact DAT’AIR for further information on:
- Enhanced adjusted EO via the inclusion of ground control
- Enhanced imagery
- Horizon up oblique
- 16-bit TIFF
- Color adjustments per view or across all views
- Image sharpening
- 3D surface models
- 3D terrain models
- Ortho rectified nadir mosaic
- Aerial Oblique Imagery view and information extraction/exploitation solutions
The geometric fidelities recently obtained on projects flown with Dat’Air’s cameras have provided precisions below 0.4 pixels simultaneously across all looks, relative accuracies of less than 1.5x GSD for 2D and less than 2x GSD for 3D processing. When applying ground control, absolute accuracies are less than 2x GSD for 2D and less than 3x GSD for 3D processing.
Obviously the accuracies of the data will be determined by several factors that most of you, as professionals in the industry are already aware of, including available base station data, ground control, image resolution, etc…
