摘要:

从二维图像重建三维图像是计算机视觉的核心问题。最近的工作一直集中在重建直接从一个单一的图像。然而,众所周知,仅一个图像不能为这样的重建提供足够的信息。由于3D CAD模型在网上的普遍存在,它已经被接受了。一个基本的问题是如何compensable表示数以百万计的CAD模型,同时允许泛化到新的不可见的对象与精细缩放的几何形状。介绍了一种三维网格的压缩表示方法。我们的方法首先选择一个3D模型,从一个图形结构,通过使用一种新的自由变形FFD 3D-2D注册,然后选择的3D模型进行细化,以最好地适应图像轮廓。我们进行了全面的定量和定性分析,展示了令人印象深刻的密集和现实的3D重建从单一的图像。

英文摘要:

3D reconstruction from 2D images is a central problem in computer vision. Recent works have been focusing on reconstruction directly from a single image. It is well known however that only one image cannot provide enough information for such a reconstruction. A prior knowledge that has been entertained are 3D CAD models due to its online ubiquity. A fundamental question is how to compactly represent millions of CAD models while allowing generalization to new unseen objects with fine-scaled geometry. We introduce an approach to compactly represent a 3D mesh. Our method first selects a 3D model from a graph structure by using a novel free-form deformation FFD 3D-2D registration, and then the selected 3D model is refined to best fit the image silhouette. We perform a comprehensive quantitative and qualitative analysis that demonstrates impressive dense and realistic 3D reconstruction from single images.
