3D data registration algorithm based on invariant was proposed, which is sparse range image from stripe coded structured light system. The range image is uneven and its corresponding points during different views are not the same ones, but the adjacent regions. The algorithm is improved iterative closed points algorithm; invariant is added during search corresponding points such as the volume of tetrahedron. The impact of volume on noise, rigid translation, and perturbation are analyzed by means of statistics experiments, and then the search criterions are proposed. Experiments verified the validity of the data registration algorithm from the quantitative and qualitative aspects.
