Define the Principal Plane.
Think about how this plane relates to the camera's position.
What is the role of the perspective center in aerial photography?
Consider where the camera takes measurements from.
What is the principal plane in photogrammetry?
Remember the definition we discussed in class.
The perspective center helps in processing aerial photographs: True or False?
Think about its significance in measurements.
Given the tilt angle of a photo, derive how this might distort the perceived heights of buildings in the image.
Consider trigonometric functions to solve for heights.
If the focal length is increased, how will this mathematically affect the distance measurements taken from the principal plane?
Refer back to the relationship between focal length and scale.
