Abstract: A three-dimensional (3D) scanner, which is in communication with a display, includes one or more optical sensors. The scanner scans, using the one or more optical sensors, an object having a surface. The scanning generates data corresponding to a 3D shape of at least a portion of the surface of the object. The scanner generates a 3D reconstruction of the shape of the surface of the object. The scanner provides a preview of the 3D reconstruction of the at least portion of the shape of the surface of the object. The scanner provides, to the display, for rendering with the preview of the 3D reconstruction of the at least portion of the shape of the surface of the object, an indication of at least one of a quantity or a quality of the data corresponding to the 3D shape of the at least portion of the surface of the object.

Abstract: A three-dimensional (3D) scanner includes a housing, one or more light sources, one or more optical sensors, a plurality of processors in communication with the one or more light sources and the one or more optical sensors, and memory storing instructions for generating data corresponding to a 3D shape of a surface of an object by repeatedly performing the operations of: projecting, using the one or more light sources, structured light toward the surface of the object; and while projecting the structured light toward the surface of the object, acquiring, using the one or more optical sensors, an image of the surface of the object. The 3D scanner further includes a cooling manifold internal to the housing comprising a single piece of metal thermally coupled with the one or more light sources, the one or more optical sensors and the plurality of processors.

Abstract: The invention relates to the field of measurement technology and relates to methods for measuring profiles of three-dimensional objects. With the aid of a projector, a previously known image which comprises non-intersecting lines is projected onto an object. The reflected signal is recorded with the aid of two cameras which are arranged at different distances away from the projector and which form different triangulation angles between the central beam of the projector and the central beams of the cameras. The distance between the projector and the closest camera is selected in such a way that the triangulation angle of the central beam of this camera and of the central beam of the projector is equal to the arctangent of the ratio of the distance between the projected bands to the depth of field of the camera lens.
