Hi,

Can the vslam map of voxl qvio be exported and imported? And if it can import a previously exported map, will the qvio drift be reduced?

Thanks!

Dong

QVIO does not perform SLAM, only visual tracking to aid in stability by tracking the velocity vectors of key points through a camera.

https://gitlab.com/voxl-public/voxl-sdk/services/voxl-mapper performs mapping and planning. Data can be imported and exported through VOXL Portal with "Load Map" / "Save Map"
