Hi,

Can the seeker perform SLAM navigation in dimly lit or completely dark environments?

Thanks,

Dan

Dan,

TLDR is you need enough features for QVIO to pick points out for VIO. So you either need a diffuse light source that can illuminate features or some other low-light sensor that you would need to integrate with QVIO.
