1. A non-contact acquisition and measurement method for identifying moving three-dimensional objects within an identification area, comprising the steps of: (1) detecting the presence of a moving object by scanning said identification area with a first eye-safe laser-camera system, (2) discriminating between an object safe to be identified and an object not to be identified, (3) for an object to be identified, activating a second laser-camera system and determining the speed and position of said object with said second laser-camera system, (4) when said object to be identified reaches a position located in an active measurement area within said identification area, activating a third laser-camera system to acquire range data of said object, and wherein said first eye-safe laser is a Class 1 or Class 1M laser and said second and third lasers are at least Class 2 lasers.
