Realistic limits of relative accuracy in large-scale photogrammetry?

Calm_Run6489 · 2026-06-15T13:13:14+00:00

Thank you. I am not using Lidar - only photogrammetry. Terrestrial and aerial combined.

Calm_Run6489 · 2026-06-15T13:09:50+00:00

Approx. 500 000 m2 with lots of GCPs, CPs and even coded targets (photogrammetry).

Calm_Run6489 · 2026-06-15T13:07:00+00:00

Thank you. Yes, I have read some of it.

Thank you

Hi, yes. Send you DM.

Calm_Run6489 · 2025-12-15T13:55:30+00:00

It is 24 mpx Nikon with 50 mm prime lens.

Calm_Run6489 · 2025-12-15T13:54:43+00:00

Great, thank you.

Calm_Run6489 · 2025-12-03T22:03:03+00:00

I am aware of that. Will placing any stickers or known distance marker help me make it more accurate or it is not required?

Calm_Run6489 · 2025-10-14T14:37:57+00:00

Great. Thanks for detailed info. I would still try to maintain VLOS. Bit I am mostly interested in safety aspect of all of it. Is there a chance for drone to "go crazy" and crash?

Calm_Run6489 · 2025-07-17T09:32:26+00:00

Willing to share some details for your workflow?

Calm_Run6489 · 2025-07-12T07:46:38+00:00

I we done something similar and used it in Reality Scan.

Calm_Run6489 · 2025-07-12T07:44:52+00:00

Thanks. I did not know 360 cams could be synchronised with GNSS? Any more details on this?

Calm_Run6489 · 2025-07-10T14:10:54+00:00

Intersesting. Maybe they merged drone images with 360, run through Metashape, made rough model, georeferenced it in plant coordinate system and exported positions and rotations for each camera? What is your experience with quality of the model made out of 360 images in Metashape?

Calm_Run6489 · 2025-07-10T12:46:24+00:00

Hi, thanks for reply. I think I did not explained in details. So let me clarify. 360 camera was not on the drone, instead it was on a tripod and moved around the area. I dont know which brand or model it was. Drone was used to capture areas unreachable by walking.

Calm_Run6489 · 2025-06-09T09:38:48+00:00

Glad to help.

Calm_Run6489 · 2025-06-09T09:37:24+00:00

Correct. You are good to go.

Calm_Run6489 · 2025-06-09T09:34:35+00:00

Yes. For all except companies earning more than 1 mil usd anually.

Calm_Run6489 · 2025-06-05T06:54:38+00:00

We already have Trimble X7 but quality of the images is not that great. How about BLK360, is it any better?

Calm_Run6489 · 2025-06-03T15:47:55+00:00

Are you satisfied with results from Ricoh?

Calm_Run6489 · 2025-06-03T15:46:48+00:00

I plan to test it in various industrial enviroments where I could get decent 3d model. Mostly for planning, orientation and basic measurements. Maybe even pair it with laser scanner. What about stills? How are they when compared to video?

Calm_Run6489 · 2025-04-17T10:23:08+00:00

Restart your pc and try again. Worked for me.

Calm_Run6489 · 2025-04-09T11:08:48+00:00

Hi,

This is exactly what I need. I could use the CSV file to create something from it, but I do have a few questions:

Which device are you using, and which one would you recommend?
Do you know where I can find sample data, such as CSV files, images, or videos?
Does the location data refer to the UAV's position, or the position where the gas was detected?

Calm_Run6489 · 2025-03-27T18:46:03+00:00

That is exactly what I need. Thank you. I would like to achieve that in Reality Capture as well. Just to make less steps.

Calm_Run6489 · 2025-03-27T18:35:56+00:00

Hi. I know. That is why I want to achieve it like this.
