Considering the dental CBCT images' characteristics, the method of deformable surface of 3D triangle mesh model is proposed. The method uses a deformable model which is initialized from an icosahedron and evolves to fit the teeth's surface by the application of the locally adaptive external forces computed from the image data and internal forces coming from the model itself. The experimental results indicate that the proposed method is robust and accurate.
考虑到牙科CBCT图像的特点,提出了一种基于三维三角形网格模型的可变形曲面方法。该方法使用一个从二十面体初始化的可变形模型,通过应用从图像数据计算得到的局部自适应外力和模型本身的内力,使其进化以拟合牙齿表面。实验结果表明,该方法具有鲁棒性和准确性。
