Abstract

A method for measuring and registering three-dimensional (3D) by measuring 3D coordinates with a 3D scanner in a first registration position, measuring two-dimensional (2D) coordinates with the 3D scanner by projecting a beam of light in plane onto the object while the 3D scanner moves from the first registration position to a second registration position, measuring 3D coordinates with the 3D scanner at the second registration position, and determining a correspondence among targets in the first and second registration positions while the 3D scanner moves between the second and third registration positions.
