Aerial navigation without GPS

This demonstration used a MEMS IMU (cost below $5), which was inside the cockpit to reduce vibration noise from the engine, and a consumer-grade barometer. The performance in this test was mostly limited by insufficient noise isolation in the camera. The SDK can also utilize magnetometer data, but that was not required here.
The software in this test consists of two main components:
1. Visual-Inertial Odometry (VIO), which is already available in our commercial SDK
2. A Visual Positioning System (VPS) component, which uses the aerial-imagery-based reference map
This component is not a part of our standard SDK. If you are interested in early access of the VIO+VPS solution, send us a message at www.spectacula...
