SRC Digital Twin

What if you could relive the Stanford Robotics Center Grand Opening in full 3D? The SRC Digital Twin project brings the latest in 3D reconstruction to the SRC website, allowing you to interactively move around each bay and demo just as you would in person. Catch us in the Alumni Center for a teaser of your visit, and take our demo home via this website.

We adapted recent work from our lab on outdoor digital twins (e.g., for cities, wildfire-prone environments, and lunar surfaces) to the indoor space of the Stanford Robotics Center. We collected imagery across different devices (mobile phones, tablets, DSLR cameras, and robotics cameras) before and after the SRC demos were installed for the SRC Grand Opening. In line with our past work, the distribution of camera positions and orientations is critical to ensure that the space and demos are reconstructed well with minimal unobserved regions. The underlying 3D representation is a Gaussian Splat, whereby the scene is parameterized with Gaussian distributions in 3D space. Each Gaussian has an associated opacity and view-dependent color that ensures photorealistic renderings. Finally, we used recently available services to create and host the Gaussian Splat reconstructions to integrate the digital twins into the website.
