用距离扫描仪或视频图像生成的3D网格模型，由于其他对象和对象本身的许多遮挡，经常会出现孔洞。本文提出了一种填补不完备模型中缺失部分的新方法。通过最小化能量函数来填充缺失部分，该能量函数是基于缺失区域与对象其余部分之间的局部形状相似性来定义的。该方法可以在缺失区域生成复杂且一致的形状。在实验中，将该方法应用于含有缺失零件的复杂形状物体，成功地证明了该方法的有效性。
3D mesh models generated with range scanner or video images often have holes due to many occlusions by other objects and the object itself. This paper proposes a novel method to fill the missing parts in the incomplete models. The missing parts are filled by minimizing the energy function, which is defined based on similarity of local shape between the missing region and the rest of the object. The proposed method can generate complex and consistent shapes in the missing region. In the experiment, the effectiveness of the method is successfully demonstrated by applying it to complex shape objects with missing parts.
