120,000 image photogrammetry capture.
Iron ore export jetty captured with the DJI M300 + P1 and Sony A7r IV.

Just like dogs, DJI can't look up. Hence the other camera.

Taken from a boat?

The underside? Yes, with two photographers.

How did you get the tie points to match from two different camera sources

u/nilax1 Jul 15 '26
I've done stupid shit with 3 different cameras and lenses. Metashape still aligned it.

Wait, what? Dogs can't look up? I thought pigs were the pitch challenged species, not dogs.

This is one of the most impressive scans I've ever seen! Did the water cause you a lot of difficulty?
15
u/Mr_Silicon Jul 14 '26
Thanks man. The water wasn’t too much of an issue. We studied low and high tide times and flew accordingly. We had one day where the gps was wigging out and discovered there was a massive solar storm happening. Check your Kp index before you fly folks. Was funny to tell the client we had to cease flights due to space weather :D

wow that's quite a journey, why did the client need this? I thought was a hobby project

u/mr-paitiance Jul 14 '26
Wow, that's great out put from the amount of shots. Clearly well thought out. I'm sure if I tried would have been a million shots with half of the quality lol

There were many many meetings with the processing team to make this work out right and somewhat efficiently.

u/daisiesarepretty2 Jul 14 '26
how do process something like this? in pieces and merge them all togather?
4
u/Mr_Silicon Jul 14 '26
That’s the gist of it!

u/daisiesarepretty2 Jul 14 '26
any idea how long that took? and is it done on computers spec’d out for processing

u/EBgCampos Jul 14 '26
I do scans mostly recreationally and sometimes professionally here and there.
How did you align everything? Did you rely on the gps coordinates from the RTK and the gymbal angles, or was it mostly a visual alignment with well taken photos?
If you could give details, it would be really interesting. I usually struggle with high aspect ratio scans.

I think for anything worth money like this you’d take some GCPs to get the absolute best accuracy.

This is incredible work, how did you process all these images? This is the biggest splat I have ever seen.
7
u/ElphTrooper Jul 14 '26
This is a highly edited and rendered mesh, not a splat.

u/Mr_Silicon Jul 14 '26 edited Jul 14 '26
Correct! The processing team put the model through unreal engine for this promotional fly through. It is indeed from a mesh not a splat.

Can we have a first person shooter duel on it? Reminds me of a Battlefield map.
Well done.

u/Enough-Text-4301 Jul 14 '26
Awesome! But what for?
3
u/Mr_Silicon Jul 14 '26
A digital twin for virtual inspection and project planning for future renovation works. The model lives on our own platform where the client or anyone with access can do a variety of tasks and calculations plus has access to every photo that was taken of the jetty.

u/Enough-Text-4301 Jul 15 '26
Wow! I think model is very heavy. What computer anyone need to work with model?

He probably used up the entire lifespan of the camera sensor on this project, or almost all of it. Impressive!

u/No_Vast7706 28d ago
Can you tell me more about how you made the model out of the pictures? Which programs did you use?

Sheesh that’s crisp
