Get Heading / Direction #78

Closed yeldarby closed 2 years ago

yeldarby commented 2 years ago

Hi, is it possible to get the compass heading at a given timestamp from the SRT files? And if not, maybe compute it from the direction of travel?

Also any possibility of getting the gimbal inclination?

Generally, the subtitle logs don't include orientation. I think on some models they do, and they are labelled as F.PRY and G.PRY (PRY is pith, roll, yaw, and I suppose G stanfs for gimbal).

This library just extracts the data, but you could compute direction of travel in your own code by comparing consecutive coordinates.

Thanks! I ended up pulling flight logs via Airdata which had the full telemetry that let me match up my video with a map.
