Patent number: 10166090Abstract: The invention relates to a device for detecting the three-dimensional geometry of objects, in particular teeth, comprising a handpiece which is provided with at least one position sensor for detecting the change of the spatial position of the handpiece, and an optical device having at least one camera for capturing images and at least one light source for at least one projector. The position sensor in the handpiece initially determines the size of the change of the spatial position of the device. It is determined therefrom, how many pictures the camera can take in a defined time unit.Type: GrantFiled: June 8, 2016Date of Patent: January 1, 2019Assignee: A.TRON3D GMBHInventors: Christoph Nowak, Horst Koinig, Jurgen Jesenko

Patent number: 9050158Abstract: A method for acquiring three-dimensional images of objects uses two cameras having acquisition areas that overlap each other. In the course of a calibration method, a group of epipolar lines associated with each other is determined for each of the cameras. A specified random image is projected onto the object to be imaged. For each pixel of the camera, a first environment is determined, an associated first epipolar line is determined, and for the first epipolar line an associated second epipolar line of the second camera is determined. For all pixels of the image of the second camera that are located on the second epipolar line, a second environment congruent to the first environment is determined. The intensity values of the first and the second environments are compared with each other and a measure of agreement is calculated. A spatial position is determined by use of the previously determined transformation.Type: GrantFiled: October 6, 2010Date of Patent: June 9, 2015Assignee: A.
