This was the problem with the Shanghai panorama. The reason why the size is so false, is because in order to maintain a projection where verticals stay vertical, the panorama has been massively stretched. It's the same with trying to correct images shot when a lens is pitched up to capture a tall building in a single shot. To get the building edges straight, you have two choices - stretch the top part of the image (interpolating pixels), or shrink the bottom part of the image (throwing away resolution.
Canon 7D - Resolution: 5'184 à— 3'456px & Crop factor = 1.62
400mm and 2x TC used: focal lenght = 800mm
Field of view:
Horizontal viewing angle: 175 degree
Vertical viewing angle: 65 degree (+5 & -60)
- Horizontal FOV of hardware (held in landscape mode):
- How much pixels can be shot per horizontal degree?
((360°/1.6°) x 5184px ) / 360° = U / 360°
- What would the radius of the sphere be?
- How big is "h" (see picture above) above and under y=0?
r x cos(90° - 5°) + r x cos (90°-60) = h
- How big would be the panorama if the horizontal FOV would be 360°?
2Ï€rh = A (if 360°)
- But the FOV is only 175°
(A (if 360°) / 360°) x 175°
100328921816px or 100.3 GigaPixels
