Abstract: The invention relates to a measurement system for optically measuring an object, comprising a dental camera and an optical attachment. In this case the optical attachment comprises at least one lens, which is shaped and arranged in such a way that the optical attachment has a negative focal length so that a measurement field or a measurement volume of the dental camera is enlarged by the optical attachment.

Abstract: The invention relates to a method for performing an optical three-dimensional recording by using a hand-held dental camera, wherein the camera automatically records a plurality of individual optical recordings in succession at a defined frequency during the measurement, wherein the individual three-dimensional optical recordings are combined by means of registration into an overall recording of a dental object to be measured. Before the measurement is performed, a three-dimensional standard jaw model is displayed by means of a display device, wherein a first control point on the standard jaw model is displayed by means of 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 (10) of the standard jaw model and records a corresponding recording region of the dental object.

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.
