DIDYMOS- XR (DIgital, DYnaMic and respOnsible twinS for XR) is a three-year EU funded project that focuses on advancing the state of the art of enabling technologies that will allow creating large-scale digital twins, synchronised in real-time with the real world.


DIDYMOS-XR will research and develop robust and scalable methods for 3D scene reconstruction from heterogeneous cameras and sensor data (e.g., lidar), integrating data captured at different times and under different environmental conditions and creating accurate maps of the scene.

The digital transformation and the availability of more diverse and cost-effective methods for 3D capture has led to the creation of digitised representations of parts of our public spaces, machinery and processes, commonly referred to as digital twins. In order to realise advanced virtual reality (VR) and augmented reality (AR) applications for cityscapes and industrial environments, continuously updated digital twins are a crucial requirement. However, today’s digital representations only cover small parts of the real world, and most of them represent the static state at the time of capture.

In cases where dynamic elements of the digital twins are connected to sensors, these connections have to be mostly hand-crafted. The vision of DIDYMOS-XR is to enable advanced, more realistic and more dynamic extended reality (XR) applications, enabled by artificial intelligence (AI).
