New TextCAD framework improves symbol spotting in CAD drawings

Researchers have introduced TextCAD, a novel multimodal framework designed to enhance panoptic symbol spotting in Computer-Aided Design (CAD) floor plan drawings. This framework addresses the limitations of existing methods by more effectively integrating textual annotations with graphical primitives. TextCAD employs a Type-Attribute Correlation Encoder (TACE) to capture the compositional semantics of annotations and a Semantic Hierarchy Alignment framework with Multi-level Semantic Filtering (MSF) to fuse cross-modal information at various semantic levels. Experiments on real-world datasets demonstrate that TextCAD achieves state-of-the-art performance in symbol spotting. AI

IMPACT This framework could enhance the automation of design understanding and industrial digitalization by improving the accuracy of symbol spotting in CAD.
