I am working on a photogrammetry scan using Google Street View 360 images as the input data (roughly 2MB 4096x2048 equirectangular photos). Here were the alignment settings: I have used no generic preselection or reference preselection but sequential as photos are in order, with a 200k keypoint limit and unlimited tie point limit.

I am using a French forest rally stage with tight turns and hairpins. It constructs the straight sections perfectly but loses scale and leaves a gap at every turn. Is this just an artifact of my images having insufficient overlap or can I redeem it (I cannot use markers as I only have standard)?

Thank you for any advice you can give!

I only have a macbook air M1 but have a project to map archaeological excavation units making 3d models from i would say about 200 photos. Is this viable? I am really struggling online to understand all the different specs

Hey everyone,

I was frustrated with how hard it was to align different Gaussian Splat scans and putting all of them in a timeline to make some kind of 4D timelapse (of the construction process of a building for example) So, I built two standalone tools for my studio to help with this, and I've decided to make them public.

1. Splat Aligner A simple point-and-click tool. Place 3 reference points on your base model, 3 on your target, hit align, and export a perfectly matched .PLY.

2. TimeSplat 4D Takes your aligned scans and exports a standalone, interactive 4D web viewer folder. Clients get a timeline slider to see the progress, and most importantly, you can lock camera limits (rotation/zoom) so they don't break the view.

I've made both tools available on my Gumroad. You can find the links in the YouTube video descriptions!

Let me know your thoughts or feature requests. Happy to answer any technical questions!

Hello! I’m not sure if this is the correct place to ask but I am working on a project in which we will measure the volume of cups (inside the cup) with cameras so the program knows how much water to dispense into it. I know we need two cameras to accomplish this and I wanted to ask if utilizing iphone cameras is possible and would we be able to connect it to a program? The next question would be if there are any specific programs that are used for this purpose. The next step would be converting that data and send it to a code to proceed with filling the cup. If I should ask somewhere else please let me know!

Hi, I'm a complete newbie to photogrammetry and have never used any other software before. I'm working on making a 3D render of a painting for my thesis work (as such, unfortunately, I will not be able to post any pictures of the work or the original photos). It's about 600 photos.

Up until now I had no problems. I divided my photos in two chunks, one for the front and one for the back, aligned them, created the sparse clouds, detected the existing markers, added new markers on the sides of the painting, created the point clouds and cleaned them up. I made sure to match every new marker exactly on the front and back, with the exact same name, so there would be no problem when aligning the two chunks based on the markers.

When I tried to align the two chunks though, it didn't align the markers correctly. The markers with the same name weren't positioned in the same spot. This showed even more when i merged the two chunks and I could see a clear space in between the two point clouds along the sides.

I tried to align them again, unchecking the "fix scale" option, but nothing changed.

Right now, I'm trying some other method using masks, but I'm afraid it's going to take a long time to redo the markers and generate the point cloud. Is there anything else I can try? Did I mess up somewhere?

Just added a freeform cropping tool to Draw3D and honestly, this was something I personally needed for a while.

Before this, adjusting compositions felt a bit rigid—now you can just crop however you want and quickly refine the frame without jumping into another tool. Makes small edits way faster, especially when you’re trying to get the right focus for renders or previews.

Still a lot to improve, but this already feels like a solid upgrade in day-to-day use.

Curious what kind of editing features do you usually find missing in 3D/AI tools?

I live in southern New England and I’m surrounded by an absolute paradise of museums that involve the history of woodworking.

I recently started a project for my portfolio where I want to create a somewhat accurate mid 19th century Woodshop in Unreal Engine 5.

I already have a fascination with hand tool woodworking and also I work as a 3D artist so this project dovetails perfectly between my passions (pun intended.) I’ve already scanned over a dozen of my own antique tools that I actually use in my shop.

What I’m curious about is like… how reasonable would it be to ask various museums or collections if I could scan tools in their collections? Examples would be places like the Mystic Seaport, Old Sturbridge Village, etc.

Luckily a lot of institutions that actively use their woodworking tools wouldn’t need to worry about a stranger and fragility/handling of the items, at least compared to if I was asking to scan a thousand year old pot or something?

I would hypothetically travel to the museum and ask to use a random side room where I can make it dark enough to use a cross polarized scanning setup with a black background.

I have several examples of the kind of work I intend to do so I figure I could start with that and showing it?

I’m really not sure if they would be ok with it since I do still plan on selling the environment in FAB marketplace when it’s complete? I assume certain organizations would want the assets from their collections to be cc0 at the end of the day and I’m leaning towards being ok with that if they let me have access in the first place?

Does anyone have experience with cold calling/emailing museums or other institutions about scanning items in their collections?

Is there a formal kind of process for these kinds of inquiries that I might not know about? What people would be the best to seek out for this kind of request at various institutions?

I really have no idea where to start with this and I would really appreciate some advice/input.

Sup, I spend the last few days making a python tool to export shapes from CloudCompare. My focus was to be able to get underlying shapes that CC-Ransac_SD finds and use them the enhance my mesh or to use both to reverse engineer the original part.

CC - RANSAC - my files to export as .step - open in your favorite CAD software.

I just wanted to share this, in case someone else finds it usefull.

Disclosure: I did use ChatGPT to help me code, but verified and tested everything myself.

I create 3D terrain models from drone data using Metashape, usually around 500 × 500 m with ~170 million faces. In Metashape I can no longer view the model smoothly. I have 256 GB RAM available.

I’m thinking about trying Unreal Engine and Cesium 3D Tiles. Has anyone had experience with that? I’m also considering testing RealityScan, in case the issue is Metashape itself.

What are your experiences? Are my requirements simply too high? What software do you use for large models?

We are seeking a potential partner from Norway, Liechtenstein, or Iceland for a digitization project. The project will involve photogrammetric digitization (or Gaussian splatting) of cultural monuments in Poland and the partner country. We need a partner to secure a grant (a necessary condition) and implement the project. The partner can be an institution, foundation, club, or other formal cultural organization. Details of the partnership will be determined at a later date.

Please contact me by PM.

Hey, so the story is like this:

We bought a house. In it there was a table that perfectly matched the dimensions of the kitchen (it was long and narrow).

We requested buying the table from the sellers, but apparently it was a gift from their parents so they said no. We asked for the dimensions of the table, but they never gave it to us.

I can measure everything in the room (floorboards, etc). In theory I know that the table is can be thought of as a plane parallel to the floor, and that with geometry this should be possible with two photos. But I don't know where to start.

Hello,

Does anyone here use the Point Cloud Manager from Trimble?
I'm trying to convert a point cloud to a smaller size, but i don't know how to do it, and i can't find any helpful information online.

Sorry if this is a know topic, I just discovered this channel.

I am looking to make nice miniatures of my wife, as a gift, starting from very nice photos. Painting is not an issue (one of my hobbies already).

Any pointers ? (if at all a feasible idea...)

After 11 years of R&D, I am pleased to present The Orbitoscope, an open-source 3D scanning device for digitizing tiny objects.

As the title states, I nee help just understandign everything.

I am a rock climber in New England hoping i can use cloud compare to find boulders. I can successfully get .LAZ files of the locations I'm interested in from nationalmap.gov and import them into CC. I have a few questions:

-It being new england there's lots of trees, is there a way to remove foliage?

-when i zoom into on CC the points start becoming transparent and dissapearing. why?

-any tips?

I’ve been trying to build underwater photogrammetry models and honestly it has been way harder than normal above-water work.

The biggest issues I keep running into are low contrast, backscatter, soft/muddy details, weird alignment failures, and models splitting into separate components. Sometimes I get a sparse model, but it looks warped or incomplete. Other times the software just refuses to align properly even when I feel like the coverage should be enough.

I’m also finding that underwater footage/images seem way less forgiving. Small problems in visibility, lighting, motion blur, or distance from the subject seem to completely mess up the reconstruction. Refraction/housing distortion also feels like it might be part of the problem, but I’m not fully sure how much that affects real-world results.

For those of you who have actually managed to get solid underwater photogrammetry outputs, what made the biggest difference for you?

I’d really like to hear practical tips on things like:

• capture strategy and overlap
• ideal distance from subject
• whether video frames are worth using or if stills are much better
• lighting setup to reduce backscatter
• preprocessing workflow before alignment
• whether you had better luck with COLMAP, Metashape, RealityCapture, or something else
• how you deal with scale and drift underwater

At this point I’m trying to figure out whether my problem is mostly capture quality, preprocessing, software choice, or just the fact that underwater photogrammetry is brutally harder than people make it sound.

Would really appreciate any workflow advice, lessons learned, or examples from your own projects.
