| 摘 要： | 提出一种基于射线的球面调和检索算法,通过规范化预处理将模型平移到坐标原点,然后通过计算三维模型表面的点到所在三角形面片的投影的最大值来构建球面函数,并对其进行球面调和变换,从而构成了一个具有平移、缩放、旋转不变的特征向量。通过实验证明,它是一种不错的三维模型检索方法。

| Abstract: | Presents a spherical harmonic retrieval algorithm based on ray projection translates the model to coordinate origin throuth the standardized pretreatment,and by calculating the three-dimensional model of the surface where the triangle points to the maximum projection of the faces,builds spherical function,and makes a spherical harmonic transformation,thus constituting a translation,zoom,rotation invariant feature vector.The experiment proves that it is a good three-dimensional model retrieval method. |
