ABSTRACT:
This device for the three-dimensional recording of a scene (4) comprises a laser emitter (20), elements for scanning along two rotation axes (16, 44) in order to scan the scene using a laser beam emitted by the laser emitter (20), a photosensitive receiver (46) for receiving an image of a spot (52) created by the laser beam on the scene (4), element (38, 50) for focussing the laser beam backscattered by the scene (4) towards the photosensitive receiver (46), first measuring element for measuring the orientation of the beam leaving the scanning element and second measuring element for measuring the distance between the device and the spot by laser telemetry.
