333 6MP pictures and a nice telephoto lens?
The approach
The 2.5 gigapixel image is a composition of images rather than a single image. TNO developed a sophisticated approach to merge the many images - all 600 of them. The photos were taken automatically using a modern consumer camera and a powerful 400 mm lens. The camera was positioned automatically using a computer-controlled pan-tilt unit. Each of the 600 photos overlaps, an arrangement that ensured very accurate positioning and enabled us to stitch the images automatically into one giant image of 78,797 by 31,565 pixels. The most difficult tasks were processing these large images and comparing the overlapping images.
Long 'exposure time'
All 600 photos were taken over a period of 1 hour and 15 minutes. Taking a single photo and moving the camera to a new position took approximately seven seconds. Thanks to the long 'exposure time', some interesting artefacts are visible at the edges of the various photos. They include a parked car that seems to merge into a bus and a walking torso.
After the photographic session, considerable effort was required to calculate the final result. It took about 24 hours to compare the overlapping photos and optimise them. Stitching the photos into one image required the capacity of 5 high-end pcs for three full days.
The final result allows the viewer to zoom in on the city of Delft and its surroundings at a resolution never seen before.
More details about the approach.
they Used a Nikon D1X and a 400mm from this pics its a lens that zooms to 400mm and its not the 80-400vr so IDK what it is, 200-400vr possibily?
