Vectorization-Free Reconstruction of 3D CAD Models from Paper Drawings

摘要

We propose a new approach for the reconstruction of 3D CAD models from paper drawings. Our method uses a combination of the well-known fleshing-out-projections method and accumulation techniques from image processing to reconstruct part models. It should provide a comfortable method to handle inaccuracies and missing elements unavoidable in scanned paper drawings while giving the user the chance to observe and interactively control the reconstruction process.
