Recent Study on a High-Precision Registration Technology Based on Bundle Adjustment in Structured Light Scanning System

In this paper, we propose a high-precision registration method based on multiple view geometry theory in order
to solve this problem. The most effective methods of obtaining three-dimensional(3D) surface data of objects,
structured light scanning system based on binocular stereo vision has been widely applied in the fields of reverse
engineering, relic preservation, biomedicine. The multiview 3D data registration precision will decrease with the
increasing number of registrations when measuring a large scale object using structured light scanning. First, a
multiview network is constructed during the scanning process. The bundle adjustment method from digital close
range photogrammetry is used to optimize the multiview network to obtain high-precision global control points.
After that, the 3D data under each local coordinate of each scan are registered with the global control points.
The method overcomes the error accumulation in the traditional registration process and reduces the time
consumption of the following 3D data global optimization. The multiview 3D scan registration precision and
efficiency are increased. Experiments verify the effectiveness of the proposed algorithm.
