Abstract: Disclosed is a dynamic three-dimensional imaging method that allows the generation of a three-dimensional numerical model that represents an observed three-dimensional scene. The generated model optimally combines (404) data from two intermediate three-dimensional numerical models, respectively obtained by a stereoscopic three-dimensional reconstruction calculation method (402) and by a method of three-dimensional reconstruction calculation through learning (403). In addition, each new model that is generated helps to improve the overall performance of the method of three-dimensional reconstruction calculation by learning.

Abstract: The device for visualizing the interior of a patient's mouth, includes a camera for taking an optical imprint of organs arranged in the mouth. The device includes augmented reality glasses having an optical glass through which a user of the glasses can see the inside of the mouth, and a visualization camera taking an image of what the user sees through the optical glass. First images corresponding to those taken by the visualization camera are correlated with second images corresponding to those taken by the camera for taking an optical imprint, whereby the second images can be projected onto the optical glass.

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.
