This calculaton was requested by Ricsi-viragosi. Simply put, dudebro wants to know how far away the mountains are in this image, given that they are 800m tall.
ANGSIZING[]
Height of the mountains = 800 m
Using the angsizing equation of
- 2atan(tan(70/2)*(object size/panel height))
- Mountain size = 99px (orange line)
- Panel height = 245px (black line)
- 2atan(tan(70/2)*(99/245)) = 0.378 rads
1 radian = 57.2958 degrees. Therefor 0.378 radians = 21.677 degrees
Then I plug that answer into the angsize calculator, and Bob's your uncle
Distance from 'camera' to the mountains = 2089.2 meters, or just over two kilometers
