1. A method of combining at least two two-dimensional (2D) images into a three-dimensional (3D) image, the method comprising steps of:
providing an augmented reality (AR) camera; providing a 3D metrology instrument having a frame of reference, the AR camera being separate from the 3D metrology instrument, wherein the 3D metrology instrument is selected from the group comprising a laser tracker, a time-of-flight (TOF) laser scanner, and an articulated arm coordinate measurement machine; in a first instance, forming a first 2D image with the AR camera in a first location; in a second instance, moving the AR camera to a second location that is different from the first location, and forming a second 2D image with the AR camera; finding at least three cardinal points in common to both the first and second 2D images; registering the first and second 2D images to obtain an unscaled composite 3D image based at least in part on the at least three found cardinal points; identifying a first selected cardinal point and a second selected cardinal point from among the at least three found cardinal points; measuring 3D coordinates of a first reference point and a second reference point with the 3D metrology instrument, the first reference point and the second reference point being within a region covered by both the first 2D image and the second 2D image; determining 3D coordinates of each of the first and second selected cardinal points based at least in part on the measured 3D coordinates of the first reference point and the second reference point; and creating the 3D image as a scaled composite 3D image from the determined 3D coordinates of each of the first and second selected cardinal points, and from the unscaled composite 3D image. |
