摘要
对基于内容的三维模型检索的应用背景和现有算法进行了研究。结合物理学的基本原理,提出了一种静电场电通量描述子,在三维模型的模拟电场中设置测试球壳,计算各个测试球壳内部的电通量,用以描述三维模型。该描述子具有平移、旋转和缩放不变的特征,并对噪声有较强的鲁棒性。实验证明该描述子具有较强的检索能力。
The retrieval methods and application of the content-based 3D model were investigated. A new 3D models electric flux descriptor was proposed on the basis of the electrical flux theory of electrostatics. The 3D model was supposed as charged body, then electrical flux was gotten by placing some testing concentric spheres around it. The electric flux descriptor is invariant to rigid transformations. Experiments show that it is a robust and effective method.
