This paper presents a global architecture of a range finder system based on the stereoscopic principle. The proposed system is dedicated to a visual intracortical stimulator in order to create artificial vision for people suffering from visual blindness. The 3D analysis of the environment is required allowing a better autonomy to the patient. The proposed device consists of an emitter projecting a light pattern from an infrared light source reflecting on a micromirror matrix. Images from the illuminated scene are captured by a camera. The three-dimensional range is reconstructed from the distortions in the reflected and captured image. Our approach to encode light patterns consists of taking advantage of a high-speed camera and adapting the Gray coded patterns to dynamic scenes.
