摘要:本文根据2013年全国大学生数学建模竞赛C题附录1的数据, 提出了确定古塔各层中心位置的八边形重心坐标拟合法，采用matlab计算出了各层的塔心坐标。利用顶层坐标相对于底层的倾斜量求得该塔的倾斜度；采用各层塔心坐标拟合曲线的曲率来描述弯曲度；并提出了利用同一个测试点与塔心连线发生的扭转角度来描述扭曲度的设想。
Abstract: Based on the title C data of 2013 National College Mathematical Modeling Contest, a method of eight shape barycenter coordinate fitting to define the old Tower' s home position was advanced, and MATLAB was used to compute every layer's kernel coordinate. The gradient was got from the tilt displacement between top and ground floor. Using the layer tower coordinate fitting curve to describe the bending curvature. An assumption of using the same test point and tower line of torsion angle to describe the tortuosity was advanced.
