Abstract: 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.
