摘要： Disclosed is a 3D scanner for recording the 3D topography of an object, the 3D scanner including: a projector unit configured for projecting a structured beam of probe light onto the object; an imaging unit arranged to acquire 2D images of the object when the object is illuminated by the structured probe light beam; and an actuator unit arranged to control the position of the structured probe light beam at the object by rotating a movable portion of the projector unit around a pivoting axis, the actuator unit including a rotation motor including or arranged to drive a wheel, where the surface of the wheel operatively coupled to the movable portion of the projector unit has a radial distance from the axis of the rotation motor which changes with the rotation.

摘要： Disclosed are a scanner system and a method for recording surface geometry and surface color of an object where both surface geometry information and surface color information for a block of the image sensor pixels at least partly from one 2D image recorded by the color image sensor. A particular application is within dentistry, particularly for intraoral scanning.

摘要： 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.
