Interpolation Question

Daren Clodio

Can some one give me a brief explanation on how interpolation works with drone heading and gimbal orientation? I am familiar with it on other apps but I can't seem to understand how its working using Dronelink.

Also when adjusting the curve of the interpolation, what exactly is it doing?

 

Thank you!

    I think the easiest way to understand the interpolation is to visualize what it does when applied to altitude in the 3D view:

    When it applies to things like headings and gimbal pitches, it does something similar, but along the axis of rotation. Does this help?

    That's exactly what I was looking for Jim!

    Thanks for your help!

    It's me again lol.

    So I have 2 markers for this waypoint. What I am trying to do is follow these two roads that will lead me to an empty lot. I have set marker #1 to simply tilt the gimbal at -19. I then set marker 2 to a poi (empty lot). What I would like to happen is when I reach marker 2, the transition is smooth from the marker 1 gimbal setting of -19 to the marker 2 (poi). When I do the mission preview the drone will get to the first maker and make the gimbal adjustment to -19. But when it gets to the second marker the gimbal makes a sudden jump and then it centers itself to the poi. I am just trying to smooth this particular issue.

    One other thing. How can I make the gimbal follow the curve of the road more smoothly? Should I have my drone follow a pathway inside the turn more while focusing on the road or is there a way to do it with my pathways directly on the road?

    You're going to get sick of me very quick! lol

    Daren,

     

    Take all this with a grain of salt.

    I am a newbie with DL also; but have been flying missions with other software for 5 years.

    I have found that to do what you want as far as the transition to the empty lot that another marker is needed to start the transition.  I added another marker #3 that starts the interpolation. You can remove it as you wish.  If you don't want people messing with your plan set your share differently.

    The experts may have a different method but that is how I have found to do it.

    Your second part is just a matter of the gimbal angle in relation to the path.  You could move inside your turn as you get closer as you mentioned.  As far as I know the only way to stay right on it with the path directly over the road is to look straight down.

    Thank you so much for clearing that up for me. I did as you said about the inside corner. I also took your advise about creating another poi marker but I just positioned it inline with the last poi marker. Seemed to be more fluid in the transition. 

     

    Thanks again for your help!

    Looks good.  Yes, you just have to adjust the POIs to get the framing your after.  If you haven't already; you can also play with setting the interpolation on the POI markers; to make them ease into the transitions.

    Take me with a whole bag of salt -- I'm not even two weeks into owning a drone...

    For what it's worth, I use what I think of as "bracketing"

    Suppose I have two POIs, and a path that meanders around them.

    I'll set two markers for each POI.  So I have marker 1 and marker 2 both commanding the camera to point at POI alpha, and markers 3 & 4 pointing at bravo.

    The reason is that I know the camera will continue to track alpha precisely while between markers 1 & 2, and will be firmly fixed on bravo between markers 3 & 4.  I set the relative positions of 2 & 3 to control where the transition between alpha and bravo begins and ends.  The closer together these two markers, the faster the transition will be.  Further apart for a more gradual, calm transition.

    This might be a stupid way to do this, but it appears to work...

    I like it Dan! Going to experiment with your idea.
