Challenge Problems
Push your limits with advanced challenges
Calculate the height of point C if the known elevation of point A is 70 m, the parallax difference (Δp) is 10 mm, and the flying height is 300 m.
💡 Hint: Use the given equation and break down the calculation step by step.
Aerial photographs are captured with a known air base of 1000 m. If the estimated parallax difference is calculated to be 8 mm, derive the approximate height of the object if the flying height was 400 m.
💡 Hint: Ensure you understand how air base and flying height affect parallax.
