Dual-resolution 3D scanner
First Claim
1. A 3D scanner for scanning a surface of an object by recording data sets for overlapping sections for the surface and stitching the recorded data sets together to provide a virtual 3D model of the surface, said 3D scanner comprising:
- a scanning device capable of recording first and second data sets of the surface when operating in a first configuration and in a second configuration, respectively, where at least some of the first data sets provide geometrical information for a lamer area of the surface than the second data sets and where the second data sets have a higher spatial resolution than the first data sets,a data processing unit configured for aligning and stitching together the first and second data sets to create a combined virtual 3D model of the surface, where the large-area first data sets provide a link between the small-area second data sets in the aligning such that accumulated stitching errors caused by inaccurate alignment of second data sets are avoided.

Abstract
An integrated 3D scanner for scanning a surface of an object, the integrated 3D scanner including a scanning device capable of operating in a first configuration and in a second configuration, where in the first configuration the scanning device is capable of acquiring a first data set relating to the surface of the object; and in the second configuration the scanning device is capable of acquiring a second data set relating to the surface of the object; and a data processing unit configured for combining one or more first data sets and one or more second data sets to provide a combined data set; where the first and second configurations of the scanning device are such that the second data set represents data with a higher spatial resolution than the first data set.
