First Claim
Patent Images
1. A method for scanning a three-dimensional object, comprising:
- scanning a surface of a three-dimensional object from a first scanning position;
scanning the surface from a second scanning position;
generating a first scanning sample including a first point cloud and a second scanning sample including a second point cloud where the first point cloud has data points that represent positions corresponding to the scanned surface at the first scanning position and the second point cloud has data points that represent positions corresponding to the scanned surface at the second scanning position;
determining coordinates of the first scanning position and the second scanning position with a satellite based positioning system; and
registering the first scanning sample and the second scanning sample based on the first scanning position and the second scanning position where the first scanning sample and the second scanning sample are oriented with respect to each other according to orientation of the surface.

Abstract
A scanning system scans a surface of a three-dimensional object from a first position and a second position. Using common alignment at these positions, a first scanning sample and a second scanning sample are generated. The first and second scanning samples include point clouds having data points representing positions of the scanned surfaces. The first scanning sample and the second scanning sample are oriented relative to each other based on the common alignment of the scan positions.

14. A scanning system, comprising:
-
a scanner that moves a scanning beam across a surface of a three-dimensional object, the scanner having a reduced degree of freedom;
a detector that detects a reflected scanning beam; and
a receiver for use with a satellite based positioning system that determines the position of the scanning system, wherein inaccuracies of the positioning system are configured to be corrected with an error signal. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
