摘要
针对网格模型无法保证弯曲变形精度问题,研究一种基于TPS插值的改进网格弯曲变形算法,对TPS插值的插值误差进行处理。该方法通过多次插值修正插值位移,降低插值误差,实现更自然更精确的弯曲变形。将算法应用到医用外固定支具的网格模型上,结果表明,算法适应性好,能满足工程应用的要求。
The accuracy of the mesh model’s deformation post-bending cannot be guaranteed.An improved mesh bending deformation algorithm based on thin plate spline(TPS)interpolation to address the inherent errors in TPS interpolation,has been proposed.In this method,we employ multiple interpolation to correct the interpolation displacement,thereby reducing the interpolation error and achieving more natural and precise bending deformation.The results demonstrate that the algorithm is highly adaptable and fulfills the demands of practical engineering application.
