We describe three calibration methods of a LED (light-emitting diode), in order to apply photometric stereo to a scene illuminated by LEDs. The most accurate of these methods will allow us to obtain very realistic 3D models.
Nevertheless, the scene must remain still during the whole shooting sequence. We thus extend this method to a LED model which takes into account the color of the light flow. This will allow us to perform photometric stereo from a unique colored image of a scene, if it is simultaneously illuminated with three colored light flows.
