融合视觉认知的工程视图理解方法研究

We proposed a hybrid CSG and B-rep method to reconstruct 3D CAD models from multi-view engineering drawings. Visual cognition is introduced into understanding engineering drawings. A visual reasoning engine is implemented to deal with the ambiguous solutions in its geometric an topologic interpretation. We also investigate how to interpret section drawings in 3D reconstruction from projections. Based on the "divide and conquer" strategy, we further provide a systematic explanation of why this approach works, and implement an experiment system to demonstrate its effectiveness and efficiency. Moreover, we explored the relevant visual cognition theory, computational models and algorithm frameworks regarding combining visual cognition with the understanding of engineering drawings. The major achievement of this project was published in a well-known international journal in CAD filed, "Computer-aided Design". The relevant paper is cited by SCI. The research output of this project has potential applications in facilitating the product modeling in CAD, the reuse of design, and human computer interaction.
