Detailed Description
A class for the essential matrix between two projective cameras.
- Date
- February 28, 2007
The essential matrix is related to the fundamental matrix by ![$E = [K_{left}]^t [F] [K_{right}]$](form_1.png)
The notation "left" and "right" refers to camera producing points used on the left side of the F or E matrix and vice versa. Note: the extract left camera function requires points be transformed to the camera focal plane. That is, e.g., left_coor(in camera focal plane coordinates) = ![$[K_{left}]^{-1} p_{left}$](form_2.png)
(in image coordinates).

Left camera extractor. Normalized correspondence pair is needed to determine which of four solutions should be used, i.e. focal plane coordinates.
The translation part of the camera is normalized to the indicated magnitude.
