Abstract: A method of scanning a 3D object includes: receiving a user's input to perform a scanning operation via a user interface, and in response using a light projector, projecting structured light onto the surface of a physical object about target positions on the surface of the physical object; and recording a sequence of first images of at least a portion of the surface of the physical object including a light scatter region illuminated by the structured light being projected about the target positions on the surface of the physical object using a camera. A trained image processing network configured during training to output data comprising a representation of positions being estimates of the target positions on the surface of the physical object in response to receiving one or more first images can be used.

Abstract: Disclosed is a method and a scanning device for digital image scanning of a surface of an object. The scanning device comprising a light source for illuminating the object. The scanning device comprising a first image sensor configured for capturing a first set of images of a first region of the object, where the first region is illuminated by the light source. The scanning device comprising a second image sensor configured for capturing a second set of images of a second region of the object, where the second region is illuminated by the light source. The scanning device comprising a laser component configured for projecting laser light onto the object. The projected laser light has a shape of a cross on the object. The first image sensor and the second image sensor are configured to capture/cover an overlapping region on the object. The overlapping region comprising a part of the first region of the object and a part of the second region of the object. The laser light from the laser component is configured to be projected onto the overlapping region. The first image sensor and the second image sensor are configured for capturing a third set of images and a fourth set of images, respectively, of the object including the projected laser light on the overlapping region.
