Dynamic Track distance?

[Tree!]

Hello All,

I've been struggling with the follow distance with the dynamic tracker. If I try to get my Autel II to track from more than about 10ft away, it gives me an error.
Is there something I need to do to get it to follow at a greater distance? From watching on youtube, I can see it's possible.

It works great on hikes, up and down mountains... its just too close.

Thanks!

I've noticed the same thing, I hope somebody chimes in with some thoughts.

Have you had any issues with it moving around a lot during Dynamic Track? Mine moves all over even when nothing is near it or I'm standing still.

For my part yes I have noticed that, although it doesn't bother me too much because I feel like it makes it a bit more interesting then simply following in a perfectly straight line but that's obviously a subjective preference.

Might be that your subject lacks sufficient contrast for the camera analysis. Try it with different shirt, hat, etc.

I know this topic hasn't been touched for a while but today I noticed the same issue with the distance. It would show a message along the lines of "maximum tracking distance reached" when it was around 20 meter (60 ft) away and 12 meters (35 ft) up. It would not lock on from further away.

Has anybody solved this issue? I've seen videos with greater distance (at least it felt like it).

Thanks in advance!

Anyone having issues tracking your dog? The software shows the dog icon when I try it on my Border Collie, and then immediately looses her and stops tracking. No matter if I try near or far from her the same issue. Anyone?

 

[Tmclerran]

Yeah. Me too. And my dog is mostly a giant schnauzer - so pitch black. I would think that because he contrasts strongly with everything the drone would track him well.
But not so. It loses him almost immediately.

And I never did figure out that too close issue. I can’t figure out how to make it track anything from 20 yards off.

There is a settings file inside Evo2's linux. Maybe its content answers some questions.

I assume that those are all in meters. Where is a dog listed?

 

[rvl]

Where is a dog listed?

I think from tracking point of view the 'person' model is applicable for humans and animals.
Another option is that file is a rudiment and the real settings hardcoded somewhere else

 

[Seakins]

Yeah. Me too. And my dog is mostly a giant schnauzer - so pitch black. I would think that because he contrasts strongly with everything the drone would track him well.
But not so. It loses him almost immediately.

And I never did figure out that too close issue. I can’t figure out how to make it track anything from 20 yards off.

Yes, mine is black also, and it doesn't seem to matter if she is on green grass, blacktop road, or a plowed field, the lock box will show her as a dog, and then immediately drop her, strange.

Dynamic Track seems to be very inconsistent. I've had similar problems. I actually came here looking for any helpful hints that may garner better results. The only thing I've been able to track was myself from behind for a couple of minutes. My dog: Nope, Other People: Nope, A Pontoon Boat: Nope, Another Drone: Nope.

It seems to recognize people & dogs but recognizing & actually tracking what was recognized seems to be disconnected.

 

[Ladiver]

Just got back from the park and I was trying to track my dog. No luck no matter what I did. It would recognize and show the dog symbol, but almost immediately after locking on, it would stop. It locked on and tracked my wife, who was with the dog, without issue.

Hopefully, someone figures that out because I would really like to have the drone follow my dog when we are off lead.
