Facing the background of active structural shape monitoring for high performance aircraft,a 3D curve reconstruction method based on the orthogonal curvatures is analyzed and researched in this paper,taken flexible fiber Bragg grating rod as the research object.With the curvatures detection principle of the orthogonally distributed Fiber Bragg Grating briefly introduced,the reconstruction method for three-dimensional curve is analyzed,while the detailed algorithmic procedure,implementation steps and analysis of continuum method for discrete curvature are given.Then a visual simulation platform is developed to analyze and verify the algorithmic procedure and the methodology with Visual C＋＋ and OpenGL employed.The performance comparison of the three type of continuum methods for discrete curvature,suggests that not only the 3D curve reconstruction method and its implementation proposed in this paper is effective but also related beneficial results about continuum method for discrete curvature are obtained.
