Abstract

A method and system for acquiring three-dimensional (3D) coordinates of a surface is provided. The method includes providing the scanner configured to emit a light from the light source and reflect the light onto the surface, the scanner further being configured to determine with a processor a three-dimensional coordinate of a point on the surface based at least in part on a first and second angle measuring device and a reflection of the light from the surface. An image is acquired of the surface with a camera and a feature is identified. A first area is identified having a high information content and a first arc segment is determined. The surface is scanned by rotating a motor at a first speed during the first arc segment and at a second speed during a second arc segment, the second speed being greater than the first speed.
