    Matrix Algebra

    I am using stereo vision to reconstruct an image into 3D but in order to do so I need to know how to find a rotation matrix. I only ever did rotation about one axis and on all the sites I've looked at the only info they give me is how to work with rotation about one axis.

    Does anybody know how to do rotation about all three axes?

    Thanks

    Euler angles

    Hi,

    You are talking about rotations using Euler angles. There are matrices that work for a rotation around a specific axis. You can take the product of each of these matrices and then you have your final rotational matrix.

    Generally all you need is the angle at which you rotate around each axis. Are there any translations?

    Check out this page for a nice description
