Abstract

The present invention describes a system for tracking (6) motion (7), making it easier to detect objects (9, 10) in space by means of artificial stereoscopic vision, using high-intensity, visible light emitters (8) synchronised with the stereoscopic vision system, at least two cameras (3, 4, 5) connected to a computer. A synchronisation module (2) controls the activation time of the light emitters (8), ensuring that all cameras (3, 4, 5) acquire at this time simultaneously. The use of high-intensity light emitters (8) synchronised with the cameras differentiates the light emitters from the surroundings, rendering the system robust, and since the light emitters need be turned on only for short periods of time, the apparent intensity is very low and they cause no interference with the users (9) of the system. The use of light emitters with various colours of the visible spectrum makes detection easy, preventing uncertainties and enhancing reliability.
