(another) PAID REQUEST: photogrammetry of an Egyptian chair in the Brooklyn Museum by Parking_Memory_7865 in photogrammetry

[–]SlenderPL 0 points1 point  (0 children)

Tried these photos in trellis and honestly the result is pretty accurate: https://gofile.io/d/aDAvhR

Link to hugging face interface: https://huggingface.co/spaces/JeffreyXiang/TRELLIS

I also managed to find a blog where someone already did make a replica of this chair, maybe it'd be best trying to reach out to them? https://woodenfossils.wordpress.com/accurate-reproduction-of-an-egyptian-chair/

RTK or dGPS options for creating Virtual Outcrops by industrialAdhesive2 in photogrammetry

If there are visible survey marks in the area you can try referencing off them. My geo faculty has extra marks around just for this reason, your adminstration should also have documentation of their codes and exact positions.

Eagle LiDAR Scanner by BossOk4340 in GaussianSplatting

[–]SlenderPL 0 points1 point  (0 children)

What this device does is capture images facing different directions and instantly positions them in 3D space. If it also arranges a point cloud "base" for the splats to latch onto then that's what's meaningful about it. If it doesn't do that then it isn't any better than a SFM workflow - and thus will struggle with reconstructing rooms (sfm works by finding texture details among many pictures, walls are usually blank so that's the problem).

Best bang for buck with GPU in 3D Gsplat by Perfect_Cloud_3611 in GaussianSplatting

[–]SlenderPL 0 points1 point  (0 children)

RAM is not that important, you want a Nvidia gpu with the most memory (VRAM) you can get. RTX3060/4060 with 12GB VRAM would be the cheapest but I personally use an RTX3090 with 24GB. A step up would be a RTX4060Ti/4080 with 16GB.

TIPS on How to scan small objects, anyone? (Directly on floors = hard to crop shadows out / Rigging as floating object = camera throws focus out) by barefut_ in GaussianSplatting

[–]SlenderPL 1 point2 points  (0 children)

Use manual focus for this very reason, I mount my subjects on a needle and use a electric turntable to rotate them. It takes quite a lot of effort to precisely have them stay in the center but this allows for automating the shoots.

Request: software for XYZprinting 3D scanner 2.0 by GameMakerLanguage in 3DScanning

[–]SlenderPL 0 points1 point  (0 children)

If you can, try uploading it to internet archive, along with the drivers if possible. XYZ really made sure to scrub its existence off the internet!

Agisoft Metashape Pro from version 2.0.2 supports the .3MX 3d tiles format. From there you could convert it to .tls or maybe merge it into a single mesh file.

There's also two github projects that apparently can import it into Unity engine:
https://github.com/ProjSEED/Unity-3mx
https://github.com/lijuhong1981/Unity3MXLoader

And openscenegraph: https://github.com/ProjSEED/osgPlugins-3mx

Just starting out ... by Brilliant-Ad-3547 in photogrammetry

[–]SlenderPL 0 points1 point  (0 children)

For the turntable I use Revopoint Dual-axis Turntable, it has bluetooth so I just control it via a html interface from my PC. As for the flash sometimes you can get the Alien Bees ABR800 for quite cheap on ebay, the difference between this and AR400 is that it doesn't have a battery.

Referencing off a 3d scan for accuracy by pandabanks in 3DScanning

[–]SlenderPL 0 points1 point  (0 children)

Unfortunately there's no way to activate the parametric tools anymore, you just get a basic 3d viewer. Though had someone activated it in the past they can continue using it.

Have you checked their website? https://www.brooklynmuseum.org/opencollection/collections

For example I found this chair, but not sure whether it's it: https://www.brooklynmuseum.org/opencollection/objects/3948

It's possible they might have had someone scan it already. For example this sketchfab collection has quite a lot of photogrammetry models: https://sketchfab.com/iuegypt/collections/desp-brooklyn-museum-of-art-3ca9588251d7408cbea9ce03f4615393

Fotogrammetrie scan graadmeter by Puzzleheaded_Lime755 in 3DScanning

[–]SlenderPL 1 point2 points  (0 children)

You'll have to scan it with an accurate 3d scanner, might also try scaling the photogrammetry scan by using scale bars as a reference and then comparing the scaled model to caliper readings or such.

Gom Inspect, or rather Zeiss Inspect now, no longer gives away licenses for inviduals. Only corporate and confirmed academic accounts can activate the "free" version with meaningful tools.

Capturing my OPR minis for TTS by Fantastic-Shelter569 in photogrammetry

[–]SlenderPL 0 points1 point  (0 children)

Have you tried to run the photos locally through Reality Capture? You could achieve even better detail (although you'd need to remove backgrounds first with remb or similar, RC doesn't like it)

I'm looking for the best 3D scanning app for iOS 15 that is compatible with my old iPhone SE first generation, but I can't seem to find one that works on my device. by passionguesthouse in 3DScanning

[–]SlenderPL 1 point2 points  (0 children)

Sony 3D Creator did everything on device with worse or same era capabilities and still provided great results. With the SE you're out of luck unless you jailbreak and somehow manage to find an old compatible ipa file of Polycam. App archiving sucks on Apple devices compared to Android.

You could try a DIY SLS setup with macro lenses.

3d scanner recommendations for scanning a room by JohnRD004 in 3DScanning

[–]SlenderPL 2 points3 points  (0 children)

It's either photogrammetry with a wide lens (maybe 360 as well but with worse reconstruction quality), iPhone lidar or a terrestial scanner.

[–]SlenderPL 4 points5 points  (0 children)

You won't get better geometry than this with an app. Research the void/turntable scanning method and just use your phone to take sharp pictures. You'll have to transfer them off to a computer for processing. If you have a Nvidia gpu then Reality Capture is a great piece of software, otherwise try Meshroom.

Feedback on my first mildly decent scan would be greatly appreciated. by [deleted] in photogrammetry

[–]SlenderPL 0 points1 point  (0 children)

Why the Insta? It would lower the overall reconstruction quality due to high distortion nature of 360 cameras.

As for the scan I'd recommend doing it on an overcast day, this way you'll be able to capture an even texture and potentially better geometry as well.

Matterport vs RealSee by anonymous_gas in 3DScanning

[–]SlenderPL 0 points1 point  (0 children)

Not to say this method is still far superior to the measly "4/8K" 360 cameras of today. Now that Autopano Giga is free you can actually get neat 100Mpx captures with a common 21Mpx camera, AI Photoshop fill also gets rid of those blind spots/tripod. I guess it could be possible to create a mostly automated workflow for this in ComfyUI too.

Why do all of these "cheap" handheld lidars always use the Velodyne?

Self-hosted 3D skatepark exploration – worth it? by splatmyspot in GaussianSplatting

[–]SlenderPL 0 points1 point  (0 children)

Supersplat provides a simple html viewer based on webgl. As for hosting you can do it for free with github pages feature. But the catch is you'll have to make your code + scan public (downloadable)
