How do i get rid of the holes

Ok newbie here, I’ve run several missions including one today which was flown on a grid pattern, and I’m happy with the 2D However the 3D is full of holes as can be seen in this image

Dataset can be found Here

Output can be found here

If it helps it’s a dronelink mission


What Processing Options did you use?

What survey plan did you use? Does it have a lower orbit with shallower gimbal angles to help capture under the eaves of the buildings?

Hope this helps

Plan was a mapping plan in dronelink, all photos taken at 285 feet ATL with gimbal at -90


You’re likely going to have gaps then, since you won’t have good enough oblique coverage.

You can try raising --feature-quality, --pc-quality, and --min-num-features, but don’t expect miracles :frowning:


Ok I’ll have a play, what if i was to take another set of photos say 100 foot lower and with the gimbal maybe at -75 and included them in the dataset, would that help, just curious, thanks for your help

Yes, that should absolutely help. Same if you can hit maybe -60 and -45 or so in addition to -75, if you really want/need the sides of objects. It should give you a much more complete reconstruction.


Ok thanks for the help, watch this space


Ok Saijin I had a play using the following settings:

This did indeed help as it got rid of that big hole in the hedge as you can see

Just need to get back out and fly it with some different altitude and gimbal angles, thanks again for helping a newbie out


Awesome! Glad you’re getting closer to what you want :smiley:

And help is what I’m here for (and also to learn from everyone else :D), so no worries.

I wouldn’t get rid of this dataset yet, either. We have some big changes landing in and just before ODM v2.8.6 that might help improve things further. But yeah, absolutely (if you can) grab those other “layers” of your flight plan with the different gimbal angles.
