Two Point Five Billion Pixels…

About a year ago I mentioned that “Some fool has decided to stitch 196 separate images together to make a gigapixel image of Bryce Canyon in Utah.” Well some more fools have decided to up the ante with a 2.5 gigapixel image of Delft University in Holland

Here are the mind boggling stats:

  • Final image dimensions: 78,797 x 31,565 pixels
  • Number of pixels in final image: 2,487,227,305 (2.5 gigapixel)
  • Final image file format: 24-bit colour bitmap
  • Final image file size: 7.5 GBytes
  • Number of source images: 600
  • Number of pixels in source images: 3,537,408,000 (600 images * 3008*1960)
  • Lens focal length: 400 mm (equivalent to 600 mm on a 35 mm camera)
  • Aperture: F22, Shutter speed: 1/100, ISO: 125
  • Horizontal field of view of final image: 93 degrees
  • Time required to capture component images: 1 hour and 12 minutes
  • Time required to match overlapping images: 20 hours
  • Time required to optimise project: 4 hours
  • Time required to compose the image: 3 full days using 5 high-end pcs
  • Time required to blend seams / correct misalignments / finalise image: 2 days

7 days work to put the whole thing together, and if it was printed out it would measure 6.67 m by 2.67 m at 300 dpi, and the level of detail in it is quite extraordinary, you can zoom in to read car licence plates… Madness.

    yeah.. pretty good and useful website for me to do a brief research on gigapixel image.
