UQ VisLab develops spatial twin linking 3D scans with live sensor data

The University of Queensland's VisLab is developing spatial twin research to capture, monitor and understand the qualities of occupied environments. The work is led by Dr Qianbin Xu and Associate Professor Fred Fialho Teixeira and extends the lab's earlier digital twin research.

The system pairs 3D scanning and point clouds with arrays of environmental and spatial sensors. Live streams record temperature, humidity, CO2, sound, light and proximity, and are shown within an interactive spatial interface so researchers can see changing conditions where they occur.

The team also intends the platform to support researchers, designers and facility managers when they compare conditions and test alternative layouts or operating approaches. The aim is evidence-informed decisions on building performance, space use and occupant wellbeing.

Why it matters: Tying sensor readings to point-cloud geometry shows a practical route from static 3D models to monitored, queryable buildings. The approach could inform facility management and smart-building projects, including those in African cities.
