| 摘 要： | 根据古塔的观测数据，分析古塔倾斜、弯曲和扭曲等变形情况。通过空间平面拟合和多边形重心公式，确定古塔各层的中心位置。以塔尖和底层中心连线的倾斜作为塔身倾斜的度量；以各层中心点连线的平均曲率来衡量古塔的弯曲情况；以拟合平面的投影旋转角度刻画古塔的扭曲程度。在获得变形数据的基础上，利用灰色预测模型对古塔变形趋势进行分析。

| Abstract: | According to the observation data, this paper analyzes the tilt, bending and twisting deformation of the ancient pagoda. Through space plane fitting and polygon center equation, the center position of each layer is determined. The connection between pagoda top point and the center of the bottom layer is used as a measure for the tilt determination;bending status is calculated by the average curvature of the connection between the centers of each layer. Distortion of the pagoda is portrayed using the rotation angle of the plane of projection. On the basis of obtained deformation data, this paper uses gray prediction model to analyze the deformation trend of the pagoda. |
