[amranov]

Hi , first i would like to thank you for this great job
i tried to run the code USING loirorVIsensor but the tracking is lost after initialization , no new KF
Also the scale value are bit weird (negative values)
IMU and CAMERA i'm using are well synchronized , any succession to solve this issue ?

-----------here is the last KF in vScaleGravityKF------------
dt = 0.000, this vs next time: 1545394068.362 vs 1545394068.362

... Map scale updated ...

... Map NavState updated ...
