Device for optically scanning and measuring an environment

摘要

A device for optically scanning and measuring an environment is provided. The device includes a movable scanner having at least one first projector for producing at least one uncoded first pattern on an object in the environment. The scanner includes at least one camera for recording images of the object provided with the pattern and a controller coupled to the first projector and the camera. The device further includes at least one second projector which projects a stationary uncoded second pattern on the object while the scanner is moved. Wherein the controller has a processor configured to determine a set of three-dimensional coordinates of points on a surface of the object from a set of images acquired by the camera based at least in part on the first pattern. The controller is further configured to register the set of images relative based in part on the stationary second pattern.

1. A device for optically scanning and measuring an environment comprising:
a movable scanner having at least one first projector for producing at least one uncoded first pattern on an object in the environment, the scanner having at least one camera for recording images of the object provided with the pattern, and a controller coupled to the at least one first projector and the at least one camera; at least one second projector is provided which projects a stationary uncoded second pattern on the object while the scanner is moved; and wherein the controller has a processor configured to determine a set of three-dimensional coordinates of points on a surface of the object from a set of images acquired by the at least one camera based at least in part on the first pattern, wherein each of the images in the set of images includes the first pattern and the second pattern, the controller further being configured to register each of the images within the set of images relative to each other based in part on the stationary second pattern.
