Research on Curve Shape Reconstruction Method Based on the Bishop Framework
This paper introduces a distributed multi-core fiber shape reconstruction method based on Bishop framework.The calculation method of fiber curvature information obtained from strain data collected by multi-core fiber is designed,and the curve equation is reconstructed with Bishop frame.Based on the simulation,the axial strain of the bent three-core fiber is extracted and verified by the algorithm.The results show that the maximum position error of the proposed method is 2.574mm at the end of the fiber,and the maximum unit length error is 0.468%,which can be used to reconstruct the shape of the fiber.
