1. A system for obtaining images of an object for 3D reconstruction, said system comprising:
a camera rig comprising a camera support structure disposed on a camera boom, a plurality of cameras disposed on a camera support structure, said plurality of cameras disposed in an arcuate array on the camera support structure;
said camera boom rotatable about a first axis to rotate the camera support structure through an arcuate path about the object, said arcuate path conforming to a first hemisphere of an imaging space surrounding the object; said camera support structure translatable to position the camera support structure in a second hemisphere of the imaging space;
a control system operable control the camera boom and camera support structure to (1) operate the plurality of cameras on the camera support structure to obtain a first set of images of the object from a first viewpoint, (2) rotate the camera support structure along an arcuate path around an axis of the imaging space and operate the plurality of cameras on the camera support structure to obtain a second set of images of the object from a second viewpoint, and so on, to obtain images of the object from multiple viewpoints in the first hemisphere of the imaging space; and (3) control the camera boom to translate the camera support structure to position the camera support structure in a second hemisphere of the imaging space and operate the plurality of cameras on the camera support structure to obtain a first set of images of the object from a first viewpoint in the second hemisphere and rotate the camera support structure along an arcuate path and around the axis of the imaging space and operate the plurality of cameras on the camera support structure to obtain a second set of images of the object from a second viewpoint in the second hemisphere, and so on, to obtain images of the object from multiple viewpoints in the second hemisphere; and
an image processing system operable to receive the images from the plurality of cameras and process the images obtained from the plurality of cameras, and reconstruct a 3D model of the object from the images.
