GPS-free drone navigation with less than 1% drift!

Spectacular AI SDK VIO tracking with two different camera devices: 1) Spectacular AI reference HW design (v1) with two global shutter stereo cameras. 2) RTK-VINS prototype device with monocular fisheye rolling shutter camera setup. Both cases also fuse barometric altitude data with VIO.

GPS is only shown for reference and no loop closures are used. The total accumulated drift is below 0.6% in both cases, when computed with optimal 4-DoF trjaectory alignment.
