bundle adjustment 大规模约束问题优化算法，用于基于特征关联的三维建模-bundle adjustment algorithm for large scale constrained problem. used in feature based 3d reconstruction.

这个程序主要是把二维翼型坐标变换成三维翼型坐标，通过翼型位置-弦长-扭角等参数得到三维翼型坐标，完成后面的三维建模-This program is mainly two-dimensional airfoil coordinate into the three-dimensional coordinates of the airfoil, the airfoil by position- to give the three-dimensional coordinates of the airfo
