Overview

The main points covered in this lecture are:

• A perspective (central) projection camera is represented by a matrix.
• The most general perspective transformation transformation between two planes (a world plane and the image plane, or two image planes induced by a world plane) is a plane projective transformation. This can be computed from the correspondence of four (or more) points.
• The epipolar geometry between two views is represented by the fundamental matrix. This can be computed from the correspondence of seven (or more) points.

Both geometric and algebraic descriptions are given.
