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: A method of operating a server computer serving a group of scanners; wherein the scanners are registered in a database with a respective indication of reservation status. The method includes receiving, at the server computer, a request for a scanning operation from a user's electronic device; wherein the request includes a user identifier and a scanner identifier; granting a reservation of the selected scanner upon reception of the request for a scanning operation, wherein the reservation lapses unless the request is confirmed within a predefined time period; and receiving, from the selected scanner, a predefined user generated event. Upon reception of the predefined user generated event within the predefined time period: maintaining the reservation until a scanning operation is terminated or cancelled, and transmitting any electronic reproduction resulting from the selected scanning operation performed at the selected scanner to the user identified by the user identifier.

Abstract: Disclosed is a device for optical scanning, comprising: a plurality of photo sensors, where the photo sensors are arranged to detect light incident on the photo sensors, emitted from a light source and reflected from an object subject to optical scanning; wherein the amount of light received at least one of the photo sensors is to a larger extent light transmitted from the light source; and to a smaller extent light reflected from the object.

Abstract: Disclosed is a method of adjusting a scanner for scanning of an original, the scanner comprising an image sensor and a light source for emitting light, the method comprising the steps of: a) moving the image sensor in order for it to be located at a predefined scanning position by means of a movable mechanical member; b) determining the difference between the scanning position and the predefined scanning position; where the method further comprises: determining the difference between the scanning position and the predefined scanning position by detecting radiation from at least one fix-point having a fixed position relative to the image sensor.
