Kaleidoscopic structured light

Full surround 3D imaging for shape acquisition is essential generating digital replicas of real-world objects. Surrounding an object we seek to scan with a kaleidoscope, that is, configuration multiple planar mirrors, produces image the encodes information from combinatorially large number virtual viewpoints. This practically useful full reconstruction object, but cannot be used directly, as do not know what viewpoint each pixel corresponds---the label. We introduce structured light system combines projector and camera kaleidoscope. then prove can accurately determine labels pixels, arbitrary kaleidoscope configurations, using projector-camera epipolar geometry. use this result show our serve multi-view hundreds projectors cameras. makes capable scanning complex shapes precisely coverage. demonstrate advantages kaleidoscopic by objects exhibit range reflectances.
