Abstract
Example methods and systems for calibrating one or more light sources are described. One example method includes determining a position of at least three photosensors relative to a world frame, controlling an orientation of at least one light source so as to cause the at least one light source to project a light beam across an area encompassing the at least three photosensors, receiving signals indicating a sensing of a light beam directed at one of the photosensors, determining orientations of the at least one light source that cause a signal at one of the photosensors, and based on the position of the at least three photosensors and the orientations of the at least one light source that cause a signal at one of the photosensors, determining a transformation from a local frame of the at least one light source to the world frame.
