Abstract
A method for measuring three-dimensional (3D) coordinates of a surface includes providing a manually positionable articulated arm portion having opposed first and second ends, providing a measurement device coupled to the first end, the measurement device including a camera having a lens and a photosensitive array and moving the camera to first and second positions and orientations to capture first and second images. Based on data from the camera, a first set of cardinal points common to the first and images and the second images are used to form a 3D coordinates that describe the surface.
