Research on three-dimensional reconstruction technology based on fault data

3D reconstruction;  branching;  contour line connection;  B-spline

The reconstruction of three-dimensional shapes from a sequence of plane contour lines has a wide range of applications, and the handling of key problems such as positioning and branching in reconstruction directly affects the accuracy and practical value of three-dimensional shapes. The key problems such as branching problem, positioning, smoothness and continuity that need to be solved when using the method are analyzed, and the solution of branching and positioning problem is improved, and it is proposed to transform the multi-branch problem into several single-branch problems according to the perimeter ratio of multiple contours to solve the branching problem and particle alignment for positioning, so as to improve the accuracy of reconstruction.
