总结我们提出了一种检索方法，由多个组件的三维CAD装配。所提出的方法区分不仅形状的三维CAD组件，但其组件的布局。两个组件之间的相似性是从构成组件的部件的特征量计算的。为了使相似性对三维空间中装配体的平移和旋转具有鲁棒性，我们使用了三维Radon变换和球谐变换。实验结果表明，该方法具有较好的检索精度和效率
SUMMARY We present a retrieval method for 3D CAD assemblies consisted of multiple components. The proposed method distinguishes not only shapes of 3D CAD assemblies but also layouts of their components. Similarity between two assemblies is computed from feature quantities of the components constituting the assemblies. In order to make the similarity robust to translation and rotation of an assembly in 3D space, we use the 3D Radon transform and the spherical harmonic transform. We show that this method has better retrieval precision and e ffi ciency than targets for comparison by experimental evaluation
