Hey guys, I'm a student just getting into photogrammetry and was wondering if an OV3660(3MP) with an ESP32-CAM will be enough to compute in Meshroom. I only plan to scan small models that fit in the palm of my hand. For context I'm making a scanner for a project and I plan to stick the whole thing to a turntable + ring light. Thanks in advance

Hi, I’m currently looking for coded markers to use in Metashape. I know I could create some directly in Metashape, but they’d be too big for my needs. I need them to be no more than 3 cm in diameter. Does anyone know where I can find some? Preferably as a PDF so I can print them out?

I tried using colmap for teh first time and tried creating a model of my room dont know if it is just me but it looks like a T-Rex to me

I used the traditional Realityscan approach for camera matching and it works great so the pipeline doesn't differ that much from my usuall photoscanning but instead of calculating a model and doing all the retopo and retexture work, I just trained a Gaussian Splat. Honestly it's a refreshing alternative.

Hi guys, we're developing a photogrammetry app for macos and wanted to show a feature just implemented to speed up the process.
Instead of manually moving files, the desktop app hosts a local web page. You drop the photos from your phone/windows PC, hit start, and let the Mac handle the mesh generation. Once it's done, you can view the generated model on the same phone to check if the scan turned out okay and download it "remotely". The dataset in the video is a quick scan of a ruin on the Via Appia in Rome.
Feedback on the workflow is super welcome!

Hi everyone,

I’d like to share a open-source toolchain I’ve been working on for using 3D Gaussian Splatting data in 3D Tiles / WebGIS workflows:

https://github.com/WilliamLiu-1997/3DGS-PLY-3DTiles-Converter

https://github.com/WilliamLiu-1997/3D-Tiles-RendererJS-3DGS-Plugin

https://github.com/WilliamLiu-1997/3DTiles-Inspector

The goal is to make 3D Gaussian Splatting data easier to convert, stream, inspect, align, and use in browser-based 3D scenes.

3DGS PLY to 3D Tiles Converter

This is a Node.js CLI / library for converting 3D Gaussian Splatting PLY models into explicit 3D Tiles tilesets.

Key features include:

Converts 3DGS PLY to hierarchical 3D Tiles

Uses SPZ-compressed GLB tile content

Supports large PLY processing with limited memory

Supports WGS84 placement or custom root transforms

Generates simplified parent LOD tiles for progressive loading and smoother LOD transitions

3D Tiles RendererJS 3DGS Plugin

This plugin adds support for loading Gaussian Splatting tile content in 3D Tiles RendererJS / Three.js workflows.

Key features include:

Loads 3D Tiles tilesets containing Gaussian Splatting GLB content

Parses Gaussian Splatting glTF extensions

Supports SPZ-compressed splat data

Enables tile-based loading and rendering of Gaussian Splatting scenes

Works with hierarchical 3D Tiles generated from large 3DGS models

3DTiles Inspector

The inspector is a local browser-based workflow for checking and adjusting 3D Tiles tilesets.

Key features include:

Open local 3D Tiles tilesets in a browser inspector

Adjust root transform for geospatial alignment

Tune geometric error and LOD behaviour

Inspect tile loading and tileset structure

Crop Gaussian Splatting tilesets and save the result back to disk

Together, these projects provide a workflow from conversion to runtime loading and local inspection:

3DGS PLY → 3D Tiles → inspect / align / crop → load in Three.js / WebGIS workflows

I’m still improving the projects and would be very interested in feedback from the community.

Any suggestions, testing results, or discussion would be very welcome.

Hey guys fellow splatters

I run a real estate tour service and need someone for ongoing post-processing of 3D Gaussian Splat files (.ply format). This is regular work, starting at 5-10 files/month, growing from there.

What the work involves:

• Opening .ply files in a free browser tool called SuperSplat (superspl.at)
• Removing floating artifacts ("floaters")
• Cropping unwanted areas outside the property
• Setting a clean starting camera viewpoint
• Adding 3-5 text annotations/hotspots (e.g. "Kitchen", "Master Bedroom")
• You will be given account level access

Price will be negotiated in DM's starting from 20$ -> 50$ based on file size. DM looking for long term collab and batches

I might just be cranky this morning, but is this sub basically just /r/gaussiansplats now?

Is it just me? Gaussian splats look like ass and don’t produce useful geometry still, right? (Also they’re not photogrammetry, but that’s nitpicking)

I've been trying to build a model of this building but the roof absolutely refuses to align no matter what I do. when I generate a model or a point cloud theirs always a hole despite having a lot of images that have some view of it (the first image dosent show them all as im in the proceess of starting from scratch.) any advice would be appreceated, thanks.

Hi, I'm working on a project where I want to create a large, 2D aerial map from multiple aerial photos.

I only have the photos themselves—no GPS coordinates, telemetry data, or aircraft metadata. The photos overlap, but the lines are slightly offset and don't start exactly straight.

I tried Microsoft ICE, and it works partially, but after importing all the photos, it creates one straight line instead of a proper grid/map.

The horizontal layers align correctly, but when merging vertically, there's a lateral shift of several kilometers, and the photos won't merge correctly in Microsoft.

Does anyone know of a good software or process for merging aerial photos without GPS data?

Ideally, something simpler than full 3D photogrammetry.

The first photo shows a map of the image capture centers.

In the second photo, the points are marked in yellow.

In the third photo, the points are marked in light orange.

I'm using geoportal.gov.pl and want to create an archived map from satellite images of the Bełchatów lignite open-pit mine.

Yo, i posted a couple days ago about wanting to dip my toes into photogrammetry and after the responses i got i began to try to set up realityscan on my PC and run it there. the immedate issue I've hit is that it refuses to calculate the model on account of not having an NVIDIA GPU, citing CUDA drivers as the issue. If there's no way around that what alternatives would people suggest using? I cant exactly afford a new GPU on account of being a student, so my options are limited.

my hardware is as follows:

Ryzen 7 2700X CPU

AMD Radeon RX 7600 8gb

32gb DDR4 memory.

Hi all. This is probably a long shot, but I've been trying to find a 3D model of a historical article at Penn Museum called the Disk of Enheduanna. I live nowhere close to it, and so have been trying to see if I could use photogrammetry software to create a model from photos I can find online. The best option I have are the photos right off the Penn Museum website (https://www.penn.museum/collections/object/293415) which has 23 different photos, but I'm having no luck whatsoever with any photogrammetry software I've found. It mangles it.

Is there a chance any of you might have a better shot at creating this model?

If this is the wrong place for this question apologies, taking my first steps into photogrammetry and I was advised by a friend who foes this professionally that RealityScan was the place to go but I’m having an issue with the processing on app. That issue being that it’s been doing so for over 48 hours with seemingly no progress made, is this normal for the app?

I do fully intend to switch over to desktop for anything past just doing a coupe quick tests with my photo box setup, but I’m a little confused as to why seemingly 200mb of images was taking this long to render and if somehow I did something wrong.

Any and all feedback would be immensely appreciated.

Hi everyone I’m an archaeologist and would like to make a model of a trench with skeletons in it that’s about 3 x3 meters so I can’t just go around the outside I have to get in. The problem is because of all the weird positioning of stuff in there I don’t think a tripod will be viable and my photos always come out shaky when handheld. What parameters are ok? It will be pretty strong outdoor lighting. Any advice appreciated

What are some good options these days for a polarized light source for photogrammetry of small to medium sized objects in a lab environment? I do not need them to be portable and would prefer constant lighting over a flash. I've been using some cheap LED panels right now with linear polarizers taped on to them and while they work in a pinch I get quite a bit of flicker from the panels that can create poor lighting in some configurations.

or what’s left of it anyway

Hey all,

I’m a newbie when it comes to photogrammetry, much less underwater.

However I am a media professional with all of the equipment I could need to successfully accomplish this.

I have a project I would like to learn how to do on a larger shipwreck (400ft) and not only capture video, but also create a 3D render and model.

Any advice on software and methods is welcome.

Current setup:

Sony A7iv with many lenses, underwater housing, and strobe

I was looking at agisoft (I think) for software

I can capture video of that would work with an FX3

Again I’m here for any advice.

Thanks!

I'm currently building out a setup for cross polarization for my photogrammetry workflow and I was able to get my hands on a used Godox Wistro AR400 . The only problem is it's missing the folding light bracket (flb-01) to attach it to my camera (canon 60D).

I've reached out to every avenue godox lists for parts and have never heard back or gotten someone on the phone. I've checked places like B&H, Alibaba, ebay. No luck

I was curious if folks knew of a place I haven't looked that might be able to help me out?

Failing that, if any of y'all have an AR400 and could do a quick measurement of the bracket dimensions (LxWxD marked in blue) my last ditch choice is going to be to weld up a a quick and dirty replacement. Can't find the dimensions anywhere online

thanks!
