摘要： The present disclosure describes a system and method for transforming a two-dimensional image of an object into a three-dimensional representation, or model, that recreates the three-dimensional contour of the object. In one example, three pairs of symmetric points establish an initial relationship between the original image and a virtual image, then additional pairs of symmetric points in the original image are reconstructed. In each pair, a visible point and an occluded point are mapped into 3-space with a single free variable characterizing the mapping for all pairs. A value for the free variable is then selected to maximize compactness of the model, where compactness is defined as a function of the model's volume and its surface area. “Noise” correction derives from enforcing symmetry and selecting best-fitting polyhedra for the model. Alternative embodiments extend this to additional polyhedra, add image segmentation, use perspective, and generalize to asymmetric polyhedra and non-polyhedral objects.
摘要翻译：本公开描述了一种用于将对象的二维图像变换为重建对象的三维轮廓的三维表示或模型的系统和方法。在一个示例中，三对对称点建立原始图像和虚拟图像之间的初始关系，然后重建原始图像中的附加对对称点。在每对中，可视点和闭塞点被映射到具有表征所有对的映射的单个自由变量的3空间中。然后选择自由变量的值以最大化模型的紧凑性，其中紧凑度被定义为模型体积及其表面积的函数。 “噪声”修正来源于实现对称性，并为模型选择最佳拟合多面体。替代实施例将其扩展到附加的多面体，添加图像分割，使用透视图，并将其推广到不对称多面体和非多面体对象。
