Best flight path method for 3D Modelling of a facility

So, we just starting using DD to make 3D models of some facilities. On this 3D Model, I did 4 circular missions with an approximate radius of 150 feet at altitudes of 60, 75, 90, and 120 feet and also a double cross with 80% overlap at 120 feet. for a total of 239 images. I used Pix4D to get the images because the DD app doesn’t have double grid. So, I loaded the images and, as you can see, there is still a good amount of distortion and errors in the model. What can I do to get a better model? the area of the facility is 100 feet by 160 feet. Any help would be appreciated. Thanks.

Hi there, have you checked out the resources DroneDeploy provides on this?

Thanks! I did see that video earlier but I think I have some more ideas to apply to the model now. I think POI mode will give the option to add more overlapping oblique images easier.

Nice, I also mentioned this earlier to another user. On my own time, I help admin a group and there’s one user in particular, Ørjan Sandland, who is doing some incredible stuff with 3D models. Please consider joining us:

Thanks Kara. I will check it out. So, I went back out and took 500 pictures of the facility using POI at lower altitudes and a more few aerials. It still doesn’t look right. I don’t know if maybe the tanks are too close together to get it perfect or if I’m doing something wrong or if there’s just too many small pipes and detail to make it look any good.Take a look 3D Model

Any other suggestions based on my 3D model. So far, with this test I don’t think 3D models will be useful for us.

Sorry to hear this, I just re-watched this video my friend (and partner in Flying Robot international Film Festival) made about creating a 3D model with DroneDeploy: He conducted an orbit around the point of interest that he adjusted as he was flying. It’s not available in DD (under the Advanced tab). Honestly, it just takes a bit of practice and tweaking. Watch this video, though. Eddie’s a genius.

Thanks again Kara. Very helpful. I’m thinking I may have used too many elevations for the obliques which caused distortions. I guess it is possible to have too much information. I will keep trying.

Ok, I hope that video gives some guidance. Also, “NOW” available in DD, sorry it correct to “NOT.” Check it out in the advanced settings.
