Abstract: A system for measuring a depth of a periodontal pocket defined by a gap between a tooth and gingiva includes a frame, one camera, and a processor. The frame is configured to be worn by a user. The camera is configured to capture at least one 2D image of an intraoral target area. The at least one 2D image includes a representation of at least a part of the tooth, a gingiva margin defined by a section of the gingiva adjacent to the at least a part of the tooth, and a probe tip when the probe tip is inserted into the periodontal pocket. The processor is configured to receive the captured at least one 2D image and to determine an insertion length of the probe tip in the periodontal pocket. The determined insertion length represents the depth of the periodontal pocket.

Abstract: A 3D scanner system includes a scanning device capable of recording first and second data sets of a surface of an object when operating in a first configuration and a second configuration, respectively. A measurement unit is configured for measuring a distance from the scanning device to the surface. A control controls an operation of the scanning device based on the distance measured by the measurement unit, where the scanning device operates in the first configuration when the measured distance is within a first range of distances from the surface and the scanning device operates in the second configuration when the measured distance is within a second range of distances; and a data processor is configured to combine one or more first data sets and one or more second data sets to create a combined virtual 3D model of the object surface.

Abstract: A scanner includes a camera, a light source for generating a probe light incorporating a spatial pattern, an optical system for transmitting the probe light towards the object and for transmitting at least a part of the light returned from the object to the camera, a focus element within the optical system for varying a position of a focus plane of the spatial pattern on the object, unit for obtaining at least one image from said array of sensor elements, unit for evaluating a correlation measure at each focus plane position between at least one image pixel and a weight function, a processor for determining the in-focus position(s) of each of a plurality of image pixels for a range of focus plane positions, or each of a plurality of groups of image pixels for a range of focus plane positions, and transforming in-focus data into 3D real world coordinates.

Abstract: Disclosed is a method for compensating for motion blur when performing a 3D scanning of at least a part of an object by means of a 3D scanner, where the motion blur occurs because the scanner and the object are moved relative to each other while the scanning is performed, and where the motion blur compensation comprises: —determining whether there is a relative motion between the scanner and the object during the acquisition of the sequence of focus plane images; —if a relative motion is determined, performing a motion compensation based on the determined motion; and —generating a 3D surface from the sequence of focus plane images.
