I would like my hexacopter (DJI F550 with APM2.0) to run a mission, return and land on a helideck all autonomusly,
The GPS does not allow for the precision needed to land on a say 1m diameter helideck, what I would like it to do is to fly using the GPS, hover over the landing area then switch over to optical flow sensor to Identify the circular shape (Shape of the helideck) and use this refrence for the final aproach and land.
Could something like this be done using the optical sensor? I have been flying my copter for a week so I am just getting familiar with its functions. I am not too happy with the mediatek precision.
If it would be possible to use optical sensing for precision landing one could integrate a charging system, inductive or direct contact into the helideck. this way it can be possible to schedule fully autonomus flights and recharge automatically for the next mission. :-).
Sadly I am not a programmer, not good enough for this task anyway, If this sounds interresting, please make some noise and discuss so that this may be possible
I think the optical flow sensor just outputs a directional vector, not an actual image. You'd be better with an app running on an Android phone, and using something like the PhoneDrone board to interface with it. It would take some programming, however.
But if you enlarge the helideck to 3m and use the 3DR uBlox 6 GPS, I think you could do it reliably just with GPS.
Chris is correct. The optical flow sensor in the store has 30x30 pixels resolution and can only be used to look for motion.
