我们提出了一种新的方法来产生制造蓝图从图像的木工项目。虽然从图像进行3D重建是一个研究得很好的问题，但典型的方法产生的表示不适合计算机辅助设计和制造应用。我们的关键见解是，制造过程定义和约束木工对象的设计空间，并可以利用开发新的重建方法。我们的方法利用特定于域的约束，不仅可以恢复有效的几何形状，还可以使用基于图像和几何优化技术的组合，恢复语义上有效的部件组装。我们在各种木制物品和家具上展示了我们的方法，并表明我们可以自动获得易于编辑和准确再现地面真实的设计。我们进一步说明了我们的方法可以用来制造捕获的对象的物理副本以及定制的版本，它可以通过直接编辑在CAD软件中的重建模型。
We propose a novel method to generate fabrication blueprints from images of carpentered items. While 3D reconstruction from images is a well‐studied problem, typical approaches produce representations that are ill‐suited for computer‐aided design and fabrication applications. Our key insight is that fabrication processes define and constrain the design space for carpentered objects, and can be leveraged to develop novel reconstruction methods. Our method makes use of domain‐specific constraints to recover not just valid geometry, but a semantically valid assembly of parts, using a combination of image‐based and geometric optimization techniques. We demonstrate our method on a variety of wooden objects and furniture, and show that we can automatically obtain designs that are both easy to edit and accurate recreations of the ground truth. We further illustrate how our method can be used to fabricate a physical replica of the captured object as well as a customized version, which can be produced by directly editing the reconstructed model in CAD software.
