PROBLEM TO BE SOLVED: To provide a scanner which may be integrated in a manageable housing, such as a handheld housing.SOLUTION: Disclosed is a handheld scanner for obtaining and/or measuring 3D geometry of at least a part of a surface of an object using confocal pattern projection techniques. Specific embodiments are given for intraoral scanning and scanning of an interior part of a human ear. The method and apparatus described in this invention is for providing a 3D surface registration of objects using light as a non-contact probing agent. The light is provided in the form of an illumination pattern to provide a light oscillation on an object. The variation/oscillation in the pattern may be spatial, e.g. a static checkerboard pattern, and/or may be time varying, for example by moving a pattern across the object being scanned. |
