4.13.2. Tilt displacement

Try these first

1. 1.

   What is tilt displacement?

   Hint

   Think about how the angle of the camera impacts the image.

2. 2.

   What is the nadir point?

   Hint

   It’s the reference point for measurements in aerial imaging.

3. 3.

   Tilt displacement refers to the change in position of objects in which type of photograph?

   • Vertical
   • Tilted
   • Horizontal

   Hint

   Consider the angle of the camera when taking photographs.

4. 4.

   True or False: The nadir point is always the center of the image.

   • True
   • False

   Hint

   Think about where the lens is pointing.

5. 5.

   Calculate the tilt displacement for an aerial photograph taken at a height of 500 meters with a tilt angle of 5 degrees. Assume the object is located 100 meters from the nadir.

   Hint

   Remember the impact of both the angle and distance from the nadir.

6. 6.

   Propose a method for adjusting for tilt displacement in urban photography to ensure accurate mapping.

   Hint

   Consider how photogrammetry techniques are applied in real life.
