TRIANGULATION SCANNER AND CAMERA FOR AUGMENTED REALITY
First Claim
1. A method of combining a plurality of two-dimensional (2D) images into a three-dimensional (3D) image of an object, the method comprising steps of:
- providing a six-degree of freedom triangulation scanner having a retroreflector and an integral augmented reality (AR) camera;
providing a coordinate measurement device having a distance meter, the device operable to direct a beam of light in a direction and measure a distance from the device to the retroreflector, and determine a 3D coordinates of the retroreflector;
determining with the device a first 3D coordinates of the retroreflector at a first position;
forming a first 2D image with the AR camera at the first position;
determining with the device a second 3D coordinates of the retroreflector at a second position;
forming a second 2D image with the AR camera at the second position;
determining a first cardinal point in common between the first 2D image and the second 2D image, the first cardinal point having a first location on the first 2D image and a second location on the second 2D image;
determining 3D coordinates of the first cardinal point based at least in part on the first 3D coordinates and the second 3D coordinates;
generating a first composite 3D image from the first 2D image and the second 2D image based at least in part on the 3D coordinates of the first cardinal point; and
storing in a memory the first composite 3D image.

Abstract
A method of combining 2D images into a 3D image includes providing a coordinate measurement device and a triangulation scanner having an integral camera associated therewith, the scanner being separate from the coordinate measurement device. In a first instance, the coordinate measurement device determines the position and orientation of the scanner and the integral camera captures a first 2D image. In a second instance, the scanner is moved, the coordinate measurement device determines the position and orientation of the scanner, and the integral camera captures a second 2D image. A cardinal point common to the first and second images is found and is used, together with the first and second images and the positions and orientations of the scanner in the first and second instances, to create the 3D image.
