1. A method for determining the three-dimensional position of a plurality of individually controllable lighting devices, the method comprising the following steps:
providing an arrangement of the plurality of lighting devices in an environment;
determining two-dimensional positions of at least part of the plurality of lighting devices with respect to a single viewpoint through acquisition, by a camera, of a sequence of images of the environment in which the plurality of lighting devices is arranged and processing said sequence of images to obtain a first two-dimensional model of the two-dimensional positions of at least part of said plurality of lighting devices;
moving the camera for determining at least a second two-dimensional model of the two-dimensional positions of at least part of the plurality of lighting devices according to at least one further viewpoint;
processing the first and the second two-dimensional models to create a three-dimensional model,
wherein the plurality of lighting devices are activated according to a pre-determined lighting state based on the number of two-dimensional positions detected, the moving of the camera being performed based on said pre-determined lighting state, and wherein the camera is moved such that the first and the second two-dimensional models always contain at least one of said plurality of lighting device of which at least a two dimensional position has been determined.
