4.14.3. Bundle adjustment

Try these first

1. 1.

   What is the primary purpose of bundle adjustment?

   Hint

   Think about how images work together.

2. 2.

   Why do we need ground control points for bundle adjustment?

   Hint

   Consider their role in mapping.

3. 3.

   What is a bundle adjustment primarily used for?

   • Refining single images
   • Aligning multiple images
   • Editing photographs

   Hint

   Think about how multiple images must work together.

4. 4.

   True or False: The collinearity equation requires at least three known points to solve for unknowns.

   • True
   • False

   Hint

   Consider how solving for unknowns works.

5. 5.

   In a project involving aerial triangulation, three ground control points were identified. Explain how you would utilize these points to perform a bundle adjustment and calculate six unknown parameters.

   Hint

   Focus on how to map the relationships between points.

6. 6.

   If a set of aerial images shows misalignment due to camera orientation errors, describe the steps taken to rectify this issue using bundle adjustment techniques.

   Hint

   Consider how realigning images impacts overall accuracy.
