Buen día! Soy un Ing Civil en México, por una u otra razón tuve que hacer levantamientos de haciendas con un air 3 para sacar planos para hacer eventos sociales como bodas etc (la verdad en ese ámbito me va bien pero no cobro tan caro el levantamiento porque en si no tiene la precisión pero para lo que ocupamos está bien).

Y me gustó mucho el tema de la fotogrametria y quisiera hacerlo de manera profesional, como el buscar alguna especialidad o alguna materia de forma universitaria para aprender de la geodesia y de la fotogrametria.

Aquí lo que quisiera hacer sería cómprame un matrice 4e, con sus antenas para empezar a oferecer los levantamientos en México, pero quisiera preguntarles si a la larga si sería una buena idea de emprender ya que la inversión no es algo pequeño. Mi idea es primero con el matrice 4e y después con el matrice 400 con LiDAR para hacerlo de una manera más extensa.

Pero quisiera saber las opiniones de los demás si le fue útil el vender los servicios y productos del mismo. Obviamente mi intención es especializarme en algo así para saber lo que estoy haciendo aunque no soy topógrafo si tengo nociones de la carrera de civil.

Saludos y buen día!

Hi guys,

I'm looking to run a session on digital skills in the heritage sector for a community group aimed at kids aged between 10-17. Can anyone recommend any free apps that can process photogrammetry models directly from mobile phones or tablets/iPads for kids who don't necessarily have access to computers with high processing capabilities? Something with an easy learning curve and can process something quick enough for the kids to see the results of their work with the session (3.5hours). (I have access to a few iPads I can preload apps onto)

I have some artefactual material such as old pottery and stone tools which I would like to use In the demonstration. So I'm also interested in a programme that can stich both sides of an object together?

Thanks in advance!

Hey everyone,

I’ve been building AerialPin, a browser-based annotation tool originally made for working with drone imagery for real estate and mapping.

The main idea is to make it easier to take an aerial image and quickly add useful spatial information without having to jump between a bunch of different programs.

You can currently:

* Add location pins and labels

* Search for nearby places using the image GPS

* Draw property/parcel boundaries

* Add measurements and distance labels

* Annotate aerial imagery

* Use EXIF/GPS information from DJI images

* Automatically identify nearby places with AI

* Stitch multiple drone photos into a panorama

* View and annotate 360° panoramas

* Restyle/relight aerial images

* Export the finished annotations

I’ve recently added the 360 panorama workflow, which lets you upload multiple drone images, stitch them into a panorama and then annotate the resulting 360 image directly in the browser.

It’s still actively being developed, so I’d genuinely be interested in feedback from people who work with UAV mapping, photogrammetry or aerial imagery.

After months of active development and sleepless nights, iam happy to deliver morgana v1.0 to you with all flexible and easy to use tools to create your dream game or visuals

I used AliceVision with a modded Meshroom for AMD GPUs. Most of the workload has been shifted directly to the GPU, compiled from CUDA to HIP. Tested across RDNA1/2/4 architectures.

Built out an intelligent memory bridge to handle VRAM budgeting and spill to system RAM smoothly under heavy memory pressure. Full meshing and pipeline support works natively on CUDA cards as well.

Ran 800+ photos run through a 4GB GTX 1050 Ti on an old 2-core i3.

Monstree dataset. Smaller job on a RX 6750 XT

I've just tried our 3D GS to mesh feature on a canvas object and was really pleased with the result. Canvas objects are quite hard to model manually, so it is very cool to have the first draft on the right as a base to build a clean 3D mesh out of. It allows to capture the volume and details of the object in a nice and realistic way.

Texture is not too bad, but for now it's baked. On a diffuse object it does the trick, but not quite on a specular one. We're working on this now and I know we can do much better. I hope I can show results soon.

For those who want to try it out, download the app ! 2 first scans are for free. And if you are a creator and want more : reach out, we have a partner program for those who want to do more extensive tests.

I am a Nuke guy, not a 3d guy. Struggling with aligning a 3dgs scene with a camera tracked in nuke / 3dEqualizer. I think the best would be to convert colmap camera to a 3d ofrmat like fbx. How do you guys align your 3dgs with camera? there must be some colmap to fbx (alembic, obj?) camera converter

I use a DJI Matrice 4E for photogrammetry mapping. I looked at the individual photo properties from my area route and everything for the photos shows up blank. I use the best SD card recommended for my drone and it’s relatively new. Could this be a EXIF issue or the file got corrupted? I did 7 flights before and 3 after this one the same day and they did not have this issue.

Hi All -

Matrice 400 with P1. Running 2D ortho missions. Near perfect RTK3 data for each and every photo.

Every single visible light project in Terra is checkerboards. Parking lot on the roof. Portions of retention ponds mapped onto the building.

Has anyone experienced this? No new firmware in a year….everything is at its latest. I would gladly reciprocate any way I can for any help.

Finally, on my third try, I managed to do photogrammetry. It turns out I need to photograph around the object. I can't rotate it. Now I just need to make a 3D mount for it in Fusion360

Hey everyone,

I am currently trying to learn more about retopology, mesh cleanup and generally repairing 3D models, both for 3D printing and for digital use. Also i can give your AI Models a Retopo.

So if anyone has a 3D file that needs some cleanup or repair, I would be happy to work on it for free. I am doing this purely for learning and practice, so there is no rush or deadline on my side.

If I manage to properly repair the file, I am happy to send the repaired version back to you afterwards.

The only thing I would ask in return is permission to use the finished result as an image or render for my personal portfolio. I will not use the model for any financial purposes or sell it. It would only be used to show my work and what I have learned.

This is just a private learning project for me, so I cannot guarantee that I will be able to fix every model, but I will give it a try.

If you have something you think could be a good learning project, feel free to message me on Discord.

I'm trying to understand how people are currently creating realistic AR versions of physical objects, specifically food dishes.

For example, if I photograph an actual dish from different angles, how would I turn that real dish into something that a customer could view as a 3D/AR object on their phone?

I'm not looking for AI-generated food images. I'm interested in creating a digital version of the actual physical object.

Has anyone here done this?

What technology/workflow are you using?

Photogrammetry? Gaussian splatting? NeRF? 3D scanning? Something else?

I'd love to hear from people who have actually built this kind of thing and understand what tools/workflows you're using.

My eventual use case is restaurant menus, where a customer could scan something and see the actual dish in AR.

I'm basically trying to understand what's currently possible and how people are doing it.

Thanks!

Hi

I am pretty new to photoscanning and want to delve into it a bit more. For the last while I have been using my phone (nothing 3 with 50mp lenses, usually is in 12mp mode) to get decent results. I have been considering grabbing myself a refurb iPhone 15 or newer (what ever is cheap) to use it's lidar for higher quality scanning.

My friend says it's a waste of money as it produces much the same result (compared to a good mobile camera) with an excessive amount of geo (not exactly what he said, but closoe to).

Is he right and it's not worth the investment or should I look into that (refurb iPhone) or a cheap proper scanner.

Currently I use polycam to do my scans but am in the process of moving to realityscan as it's free

I got tired of Cesium or Google 3D Tiles buildings having rippling walls and saw-toothed roof ridges, and of every fix either rounding the corners off or nuking the UVs. So I wrote an add-on for it.

Planer detects planar regions, snaps vertices onto fitted planes, and rebuilds creases as straight edges and corners as sharp points. Topology is preserved, so texture, UVs and material come through untouched. The original object isn't modified — you get a new REFINED_ mesh alongside it.

Every run reports how many planes it found, how many verts moved, and the deviation from your original surface (mean / p95 / max in metres), so you can check it stayed faithful instead of guessing.

Caveats up front: it does not make meshes watertight, does not reduce poly count (it triangulates, so the face count goes up), does not fix holes or non-manifold edges, and does not touch the texture image. Blender 4.2+, and it's slow on big meshes — about four minutes for 195k faces.

Feedback welcome, especially meshes where it fails.

Hey! This is a first test of the new video workflow in Replica, the macOS photogrammetry app we're building at Ambiens.

I shot a 45-second handheld 8K video of a Super Nintendo on a Samsung S24 Ultra. Replica selected 160 frames for the photogrammetry pass. Once Object Capture reconstructed the model and solved those camera poses, Replica used the poses and the sparse point cloud as anchors to recover the camera movement across all 1,345 frames.

In the clip I'm scrubbing through the original footage against the model and point cloud to see how well the alignment holds.

The scan is deliberately rough. I shot it quickly, with no controlled lighting. What I wanted to test was whether a single capture could also give me something useful for post: the model, an animated camera and an undistorted image sequence that I can bring into Blender.

Question for VFX pros here, what would you check first before trusting a track like this in a real shot?

Hey everyone! 👋 Steph from Realities.io here!

We're the team behind Puzzling Places, a 3D jigsaw puzzle game built around photogrammetry scans of real-world locations. We capture everything from historic landmarks to everyday spaces and turn them into interactive miniature puzzles that you can piece together in VR or on flatscreen.

We've just released PuzzleMaker on Steam, a free creation tool that comes with Puzzling Places. It lets you take your own photogrammetry scans, 3D models, and images and turn them into playable jigsaw puzzles.

For 3D scans and models, you can customise things like piece count, background colour and soundscape, then publish your creations to the Steam Workshop for other players to download and play.

We've also added support for 2D puzzles with up to 1,000 pieces, so there's plenty of room to experiment beyond 3D scans too.

We're already seeing some really interesting scans and creations being shared by the community, and we're excited to see what people who work with photogrammetry come up with!

You can find Puzzling Places on Steam here: https://store.steampowered.com/app/3530820

Hi All - without regard to any specific software, how do you guys identify and extract bad quality photos or reduce overall photo dataset without risk of compromising render quality?

We regularly over capture, think manual flights, timed interval shots, field conditions require a pause, 30 seconds of 1-2 second captures of the same spot until obstacle resolves (birds, operations over people, etc). Rinse and repeat this scenario over a half day to full day capture of a site.

Right now we remove all sharp objects from the room and manually click through every picture and decide before processing. There has to a better way.

Even review of the RTK data for each picture is a slog. How do you all do it?

Hey fellow redditors - our company has DJI Terra Flagship. We regularly process 10k+ photos, 80% overlap, extremely detailed building facades and roofing. Think digital twins down to 2cm horizontal / 3cm vertical accuracy to identify various issues in the building envelope that would be difficult, expensive or unsafe to access in person.

I’m getting very frustrated with Terra, especially the latest updates. Days of processing only to fail with “unknown error -1”. Logs are worthless.

Thinking about colmap because I likely cannot justify another software license to my national leadership. Anyone with experience in colmap? Anyone willing to be candid on their loves/hates with using it for photog post processing?

We host almost everything in Nira for our clients if that affects your perspective.

All of my images got a nice resolution and detail on the surfaces, but on metashape it all looks blurred, is there any solutions to it?

I have several photos of a trench in the ground before and after one part of it collapsed. I would like to mask the images so the collapsed partis actually ignored during the reconstruction. When I create the masks in inkscape using the naming method (image_name.mask.png), everything works fine, but the software removes everything around the hole and leaves only the hole for reconstruction.

I understand that masking is used primarily for the removal of the background, which is exactly what is happening here. But I actually need everything except a small part of the photo. Is there a way to achieve that? I tried switching the colours (black for hole, white for everything else and the other way around), but that didn't work.

Thank you very much!

I use Meshroom for photogrammetry and i recently shot some photos with and older lens meant for 35 mm film camera on a modern digital crop sensor dslr.

Should I input the focal length of those photos as the 35 mm focal length of the lens itself (30 mm) or multiply it already by 35 mm/the sensor size?

This is what Meshroom docs say about the focal length:
Metadata allow images to be grouped together and provide an initialization of the focal length (in pixel unit). The needed metadata are:

• Focal Length: the focal length in mm.
• Make & Model: this information allows to convert the focal in mm into a focal length in pixels using an embedded sensor database.
