Spectacular AI SDK in action

Inside-out tracking

Accurate and low-latency 6-DoF pose tracking for AR & VR headsets, without external lighthouses. Lightweight enough to run on an embedded processor in the headset.

Drone navigation

Runs real-time on embedded devices. Ideal as an input for autonomous navigation. Power consumption well below 1 W with correct acceleration.


Optional fusion with GNSS allows uninterrupted positioning during GPS outages and provides accurate orientation, even with a single GPS antenna.

Large-scale mapping

A floor area of approximately 1000m² was mapped in 21 minutes using Azure Kinect device.


Spectacular AI tools for 3DGS or NeRFs function as a more robust alternative to COLMAP that also retain information about the metric scale and orientation of the scene, based on IMU data.

Fast 3D reconstruction

The SDK can be used for quick real-time mapping and 3D reconstructions on commodity hardware such as mobile phones with ToF sensor.


Visual-inertial navigation done right

Spectacular AI SDK implements a high-performance proprietary VISLAM solution (patent pending) that represents the next step of evolution after the best-in-class HybVIO method.

We also actively participate in 3DGS research and provide certain cutting-edge features that are not currently available in any other software. Spectacular AI has also contributed to the gsplat and Nerfstudio Open Source 3DGS implementations.
