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.

木工制造感知逆向工程

我们提出了一种从木制品图像生成制造蓝图的新方法。虽然从图像进行 3D 重建是一个经过充分研究的问题,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程序。我们的主要见解是制造过程定义和约束木制品的设计空间,并可用于开发新的重建方法。我们的方法利用特定领域的约束,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来恢复零件的语义有效装配。我们在各种木制物品和家具上演示了我们的方法,并表明我们可以自动获得既易于编辑又准确再现真实情况的设计。
