Making scan results land in the right place

How we split 2D detection and 3D verification into two stages to reduce false positives in digital twin asset annotation, and how that revealed the next recall bottleneck

How we turned free-form 3D exploration into measurable coverage scanning for valve inventory in a digital twin factory

A practical engineering recap of how a simple drawing text extraction task turned into a 2D-to-3D mapping workflow for digital twins, combining SVG parsing, vision models, geometry rules, registration …

A synchronization paradigm for massive real-time data: a middle layer isolates high-frequency data sources, and React consumes only the linear projection of the visible viewport.
