Abstract: The invention relates to a method for producing a two-dimensional whole image of a recording region captured by means of a plurality of individual images, each having its own viewing direction and its own distance, wherein a spatial orientation of a main image plane of each individual image relative to a main image plane of the respective further individual image is determined on the basis of an overlap of the respectively captured subregions, and at least a plurality of the individual images are combined in accordance with the spatial orientations to form the whole image. The whole image area is the surface of a torus.

Abstract: The invention relates to a method for recording individual three-dimensional optical images (1) to form a global image (50) of a tooth situation comprising an upper jaw (2) and a lower jaw (3). A first 3D model (6) of a first subsection of the upper jaw and a second 3D model (8) of a second subsection of the lower jaw are produced from the individual images. Subsequently, a geometric positional relationship between the first 3D model (6) and the second 3D model (8) is determined, said positional relationship being determined by using a lateral image (20, 21, 22) and/or using a contact pattern (31, 32). Said lateral image (20, 21, 22) comprises an image area which comprises at least part of the first subsection of the upper jaw (2) and at least part of the second subsection of the lower jaw (3). Said contact pattern comprises several contact areas (31, 32) between the upper jaw and the lower jaw. Said contact pattern (30, 31, 32) is measured by means of an occlusion paper (29).

Abstract: The invention relates to a method for recording individual three-dimensional optical images (2) to form a global image of a dental object (1) which is to be measured. After each individual image (2) is taken by means of a dental camera (3), a computer (8) automatically checks whether an overlapping area (5, 12) between the images which are to be combined meet the recording requirements determined for a correct recording. If the overlapping area (5) meets the recording requirements, the recording is carried out between the images (6, 7) to be combined and a first image sequence (9) is set in motion. Said images of the first image sequence (9) are subsequently combined to form a first cluster (23). If the overlapping area (12) of an image (13) does not meet the recording requirements, the first image sequence (9) is interrupted, an additional second image sequence (14) is automatically started with said image (13). Subsequently, the images of the second image sequence (14) are combined to form a second cluster (24).

Abstract: The invention relates to a method for recording several three-dimensional recordings of a dental object, wherein each of the three-dimensional images comprises 3D measured data and color data of a measured surface of the object, wherein the individual images are combined to form an overall image using a computer-assisted recording algorithm, wherein first regions with hard tissue and second regions with soft tissue are identified in each of the images using a segmentation method that depends on the color data. In applying the recording algorithm, the first regions and the second regions are weighted with different weighting factors.

Abstract: The invention relates to a method for performing an optical three-dimensional recording by using hand-held dental camera. The camera automatically records a plurality of individual optical recordings in succession at a defined frequency during the measurement. The individual three-dimensional optical recordings are combined into an overall recording of a dental object to be measured and before the measurement is performed, a three-dimensional standard jaw model is displayed using a display device and a first control point on the standard jaw model is displayed using the display device. The hand-held dental camera is then positioned in relation to the object to be recorded in such a way that the camera points at the first control point of the standard jaw model and records a corresponding recording region of the dental object.

Abstract: The invention relates to a method for measuring a dental object (1) using a dental camera (2). During measurement, several optical three-dimensional images (3, 50, 51) of the object (1) are produced. During measurement, an acoustic sound (10, 12) is generated by means of a sound producer (9, 11), said sound (10, 12) being used as feedback for the user and information relating to the current status of a recording of the images (3, 50, 51) and/or relating to image requirements of the dental camera (2) are transmitted to the user. Then, each individual image (3, 50, 51) it is automatically checked by a computer (6) as to whether an overlapping area (7, 8) between the images (3, 50, 51) which are to be combined meets the defined recording requirements for a correct recording.
