Abstract
An extraoral scanner system for determining a 3D geometry of a dental object: at least one camera; a pattern generator configured to generate a probe light with a plurality of configurations in the form of an illumination pattern; an optical system configured to transmit the probe light towards the dental object, and to transmit at least a part of the light returned from the dental object to the camera to form a plurality of 2D dental data, an intraoral mirror device configured to reflect the probe light towards the dental object, and to transmit at least a part of the light returned from the dental object to the camera to form a plurality of 2D mirror dental data, and one or more processors.
Claims15
An extraoral scanner system for determining a 3D geometry of at least a part of the surface of a dental object in an oral cavity:
- at least one camera accommodating an array of sensor elements;
- a pattern generator configured to generate, using a light source of the extraoral scanner system, a probe light with a plurality of configurations in the form of an illumination pattern;
- an optical system configured to transmit the probe light towards the dental object along a first optical path of the optical system thereby illuminating at least a part of the dental object with the illumination pattern, and to transmit at least a part of the light returned from the dental object to the at least one camera to form a plurality of 2D dental data,
- an intraoral mirror device configured to reflect the probe light towards the dental object along a second optical path between the intraoral mirror device and the at least one camera, and to transmit at least a part of the light returned from the dental object via the second optical path to the at least one camera to form a plurality of 2D mirror dental data, and
- one or more processors configured to determine the 3D geometry of at least a part of the surface of the dental object based on the plurality of 2D dental data and the plurality of 2D mirror dental data and the illumination pattern.
