Hi all.

I had an interesting experience the other day and haven't been able to find anything concrete in the literature about whether this is a feature.
While performing a room inspection on my own home I was flying low to the rood. I turned the Anafi and moved forwards slowly towards the ridge line. The drone maintained it's height above the roof automatically and rose with the incline of the roof.
Is this a feature or just an accidentally pleasant glitch with the altitude control when flying low close to a steady slope?
Cheers
Rhys

As long as it is done slowly yes it will adjust, my Autel X-Star does the same thing. the cameras on the bottom are not meant for this but yes it does work if you go slow.

You have two sensors under your Anafi.

1. A camera that helps Anafi find the same place you started from when landing. The camera cannot measure the distance to the ground / your roof.

2. An ultrasound sensor that measures how high Anafi is over an object such as the ground / your roof ect. The sensor works up to a height of about 6 meters and helps Anafi keep the same distance over a fixed object at lower altitude.

3. Another sensor is the barometer that takes over at greater heights.

And yes, it is true that Anafi will follow the height of a given hard object by slow flight.

Regards, Leif.

... and in low altitude below 6 m, because this "feature" is only reached by using the bottom ultrasonic sensor.
In open terrain I would not trust this function ... ;)
