Pose estimation of 3 views based on the orthographic model.
The algorithm uses only points visible in all 3 views. It implements the Tomasi and Kanade factorization method.

Setup and Usage
---------------

MATLAB
------
1. You must have MATLAB software installed on your computer.
2. The following toolbox is required:
  * optimization_toolbox
3. Run the example script example.m to easily use the code. It contains all the necessary steps for the pose estimation of three perspective views using the orthographic model. The data used as example is in the data/ folder.

OCTAVE
------
1. You must have GNU Octave installed on you computer. You can install it in Ubuntu systems running the following command:

 sudo apt-get install octave octave-optim

2. Run the example script example.m.
