Abstract: The three dimensional measuring device used in the dental field and aimed at measuring in the absence of projection of active or structured light, includes an image-capturing device and data-processor for images. The image-capturing device is capable of simultaneously, or almost simultaneously, capturing at least two images, one of which is totally or partially included in the other one. The included image describes a narrower field than that of the other one, and has a higher accuracy than that of the other one.

Abstract: Device for taking three-dimensional and temporal optical imprints in color, including a three-dimensional dental imaging device that does not employ structured light projection. The device includes a stereo camera having at least two CCD or CMOS color 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 the sensor, controlling the latter but also the LEDs illuminating the imprint capture region. The system includes 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.

Abstract: The three-dimensional correlation of images of a human organ, especially dental arcades, uses an impression in the occlusive position, providing a reference in the form of three mutually spaced reference points. Three-dimensional views are taken of the impression and the points and views are also taken with the impression removed. Using the images of the reference points as a basis, the sets of views are then correlated to bring them into a single referential system.
