Abstract
The invention concerns a method for the contactless scanning of three-dimensional objects (1). The objects are scanned using a bundled light beam (7), preferably using a laser beam. The object is scanned in at least two different measuring sections. When scanning in two different measuring sections, the measuring lines on the object (1) are not parallel. As an alternative or additional option, the object (1) is rotated during one measuring operation and not during the other.

A method for the contactless scanning of three-dimensional objects with a collimated light beam such as a laser beam, said method comprising steps of
- scanning the object by at least two different measuring sections, and
- combining the measurement values of the measuring sections,
- wherein the lines of the measurement points of two different measuring sections are not parallel and/or the object rotates in one measuring section and not in the other in the case of two different measuring sections.
A scanner for the contactless scanning of three-dimensional objects, said scanner comprising
- a transmitter for emitting collimated light beams, such as laser beams,
- a receiver for detecting light signals,
- a holding device for receiving the object,
- means for connecting the holding device to a control and computing arrangement,
- a deflection arrangement for deflecting the light beam over the surface of the object whereby the object can be scanned by at least two different measuring sections, wherein the lines of the measurement points are not parallel in two different measuring sections and/or the object rotates during one measuring section and does not during the other one.
