Patent number: 11825062Abstract: 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.Type: GrantFiled: July 2, 2020Date of Patent: November 21, 2023Assignee: 3SHAPE A/SInventors: Rune Fisker, Henrik Öjelund, Mike Van Der Poel, Kristian Evers Hansen, Anders Gaarde

Publication number: 20230228564Abstract: 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.Type: ApplicationFiled: March 23, 2023Publication date: July 20, 2023Applicant: 3Shape A/SInventors: Nikolaj Deichmann, Mike Van Der Poel, Karl-Josef HOLLENBECK, Rune Fisker
