Disclosed is a 3D scanning system and a method for using such a system, where a handheld scanner of the 3D scanner system is used to control the operation mode of the system such that the user does not need to engage an external unit e.g. during a scanning procedure in which the teeth in a patient's upper and lower jaws are scanned.

3D scanner system with handheld scanner

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: &#x2014;determining whether there is a relative motion between the scanner and the object during the acquisition of the sequence of focus plane images; &#x2014;if a relative motion is determined, performing a motion compensation based on the determined motion; and &#x2014;generating a 3D surface from the sequence of focus plane images.

Motion blur compensation

Disclosed is a method for determining the relative arrangement of patient's jaws in a bite position when the patient's occlusion is not defined by natural teeth alone, where the method includes a step of obtaining a digital 3D representation including both surface data relating to dental tissue in one of the patient's jaws and surface data relating to a scan appliance arranged in relation to the jaw, where the scan appliance is configured for at least partly defining the patient's occlusion.

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:&#x2014;determining whether there is a relative motion between the scanner and the object during the acquisition of the sequence of focus plane images;&#x2014;if a relative motion is determined, performing a motion compensation based on the determined motion; and&#x2014;generating a 3D surface from the sequence of focus plane images.
