Shape Apperception and Reconstruction of Fiber Grating Intelligent Flexible Structure Based on Orthogonal Curvatures

摘要

with emphasis on the process of design and development method for the intelligent flexible structure distributed with orthogonal Fiber Bragg Grating sensor array, a fitting and reconstruction method based on orthogonal curvatures for three-dimensional curve and a method to make discrete curvatures continuous are analyzed with detailed algorithm processes and implementation steps in this paper. On the basis of the experimental calibration analysis with FBG model structures, a real-time apperception and reconstruction platform of intelligent flexible structures for analyzing and verifying the methodology and processes of the algorithm is developed with the technology of Visual C++ and OpenGL. The academic methodology and implementation technique are analyzed experimentally in the visualization platform. It reflects more accurately the real-time changes of intelligent flexible structures by employing an intelligent structure based on FBG as an experiment model. Experimental results prove the feasibility of the model design and the effectiveness of the three-dimensional reconstruction algorithm.
