3D reconstruction framework via combining one 3D scanner and multiple stereo trackers

摘要

This paper presents a novel 3D reconstruction framework of large objects, where we adopt one 3D scanner to reconstruct partial sections of large objects, and employ multiple stereo trackers to extend reconstruction range. Both the 3D scanner and stereo trackers are fitted with infrared light-emitting diode (LED) lights. During reconstruction, the stereo trackers are placed one after another, their poses are estimated according to the LED lights, the 3D scanner is moved to reconstruct partial sections of a large object, and the LED lights on the 3D scanner are tracked by the stereo trackers to compute the poses of the 3D scanner for partial alignment. The experimental results show that this proposed method can accurately and effectively reconstruct large objects, and has its advantages for long-range reconstruction compared with similar existing methods.
