In computer vision triangulation refers to the process of determining a point in 3d space given its projections onto two, or more, images. It tests the consistency of findings obtained through different instruments and increases the chance to control, or at least assess, some of the threats or multiple causes influencing our results. In order to solve this problem it is necessary to know the parameters of the camera projection function from 3d to 2d for the cameras involved.
