Device for taking three-dimensional and temporal optical imprints in colour which consists in a three-dimensional dental imaging device that does not employ structured light projection. It comprises: a stereo camera composed of at least two CCD or CMOS colour sensors in preset positions; an optical system of fixed and preset focal length; an LED lighting system; and an electronic system located behind or near said sensor, controlling the latter but also the LEDs illuminating the imprint capture region, and which comprises a central processing unit and a card for controlling said LEDs. The sensors are distributed over all or part of a dental arch, being placed in a sort of optical impression tray allowing a complete image of the arch to be captured in a single exposure. |
