Question 1.
What is a tilted photograph?
Show hintHide hint
Think of how the camera is positioned.
Question 2.
Where is the nadir point located in a photograph?
Show hintHide hint
It's a key reference point.
3Question 3.
What is the angle threshold defining a tilted photograph?
- 25 degrees
- 30 degrees
- 35 degrees
Show hintHide hint
Recall the specific angle mentioned in class.
4Question 4.
Tilt displacement is measured from which point?
- True
- False
Show hintHide hint
Think about the reference point for displacement.
Question 5.
A photo is taken with a tilt angle of 12 degrees, flying height of 750m, and the focal length is 35mm. Calculate the scale of a point whose elevation is 150m if its y-coordinate relative to nadir is 200 units.
Show hintHide hint
Make sure to convert degrees to radians for calculations.
Question 6.
Discuss how varying flying heights affect measurements in tilted photographs, providing an example with numerical details.
Show hintHide hint
Contrast between low and high flights, think about image clarity.
