An integrated algorithm for NRSFM with RIKs

Abstract

In this paper, an integrated algorithm is proposed to reduce the fluctuation of the NRSFM-RIKs algorithm caused by the parameter variation. In the proposed method, a grid division is first performed on the possible interval of parameters. Then, each group of values is set as the parameter values of the NRSFM-RIKs algorithm to estimate the 3D coordinates of feature points. Finally, the estimated 3D coordinates are integrated, and used as the final estimations. The experimental results on several widely used sequences demonstrate the feasibility and effectiveness of the proposed method.
