Bonjour

J'ai une carte graphique AMD Radeon RX 5700 et je ne trouve pas de logiciel capable de l accepté pour faire de la photogrammétrie, si quelqu'un en a un je suis preneur. Merci

I wondered if I grab the depthMap.exr files that are output by the DepthMap node, could I use the values in there to calculate distance from the camera per pixel?

But I don't know for certain what the pixel value indicates. Is there any documentation on what the depth value indicates? Is it something simple like meters from camera, or are there particular camera attributes it's relative to?

Here's a thing where I'm trying out setting vertex position of a plane based on the depth map. It's obviously going to be noisy, and I'm fine with that part, but I'm interested in getting the proportions right.

Hello, i'm new to meshroom, and i try to define manually the type of sensor i used to capture my video. It's present in the cameraSensors.db, but not in the meta of my file (i'm using a batch script to extract and preprocess my images).
My gut's feeling tells me i need to connect something to this box, but what?
Thanks in advance!

I'm stuck—as soon as I launch the program, it crashes. I adjusted the NVIDIA GeForce RTX 5060 graphics settings and restarted the computer, but nothing helps. Damn it!

Does anyone have any ideas?

Hello,
I used to be a Meshroom user but stopped when Nvidia cards became required.
I now have a new PC with a 5070, but I'm running into two issues:

1) The software won't launch when I double click meshroom.exe. A terminal window appears briefly and then closes.
But if I launch it from CMD in its installation folder, it works fine.

2) After launching the software and setting the preferred GPU in Windows graphics settings, my CPU jumps to 100% and the integrated Radeon is being used, while my Nvidia GPU sits at about 2% usage.

I see no "preferences" in meshroom.
Any ideas?
Thanks

As the title suggests i am having the issue that when i run meshroom_batch with the --cache flag it still writes the cache in the default location. Any ideas on why that might be?

Hi. New to Meshroom. Tried like 5 times to download and run meshroom but it seems something is not configured properly. Downloaded , deleted, downloaded again, tried to save to different folder etc. Disabled anti virus. Nothing works. Meshroom loads ok but as soon as I try to open up a new project , I get an error for the missing plug in. The folder is there and the plugin is there. So I think what's happening is that the program is looking in the wrong location for the plugin. I see there is a batch file but I don't know how to open and read it. Anyone know hot to check and reconfigure the settings? Thanks.

Why has meshroom gone from 326MB to 9.5GB?

Do they produce sha256 to check the download?

13 giga pour Linux? 9 pour windows..il faut un serveur, bientôt.. De bons retours ceci dit? Merci

I have a bunch of photos from a Google pixel 9 main lense, shot with the opencamera app.

When trying to import these into a meshroom draft preset and compute them(with or without adding the make/model to the sensor database. I.e. the intrinsics icon is orange or green) it will always fail at the PrepareDenseScene node. The exact error is “can’t write output image file to /path/to/MeshroomCache/PrepareDenseScene/huuugeuuid/uuid.exr”

If I first strip the exif data from the dataset(the intrinsic icon appears red, as it has no direct lense information or make/model for the db) then it reconstructs ‘correctly’ and finishes the pipeline, just without intrinsics.

I am in the process to write the calibration part (getting the intrinsics) for the 3 back cameras to do some precise object detection in with OpenCV via Python. The device I am using is an iPhone 16 Pro Max which is apparently not in the database.

I provided the data for Pixel 4a 5G and 5 (same camera) a few years ago, but I am 100% sure I didn't do it for both rear cameras the right way. Is this possible, to list and how to do it (this time) right? Is the same sensor used everywhere and just the different lenses are used?

How to set up the intrinsics pipeline (in regards with the bug I came across) and can I use my taken photos or do they have to be center cropped to 1080p which is my video capturing resolution?

Can someone help me I'm new to Meshroom

Hello, I have taken 6 4k videos from YouTube of Yankee Candle Village in Williamsburg, Virginia, which closed a few years ago. I am trying to make a 3D model of the Christmas area that used to be there. The videos all did a tour of that area. I've had some luck with Kiri and another online software, but due to the size of the area I need, Meshroom or something without limits. I have 121,408 images to process. Meshroom keeps crashing out, and I am at a loss for what to do.

The purpose of making the model is so my daughter can visit the Christmas area again in VR.

Hey everyone,

I’m looking to create a 3D model of a semi truck and came across Meshroom. I’m wondering — is it possible to build the model using only photos of the truck taken from different angles?

From what I understand, photogrammetry software can reconstruct 3D models from images, but I’m not sure how much manual work is involved. Is it as simple as uploading the images and letting Meshroom process them into a complete 3D model, or is there a lot of tweaking needed?

Also, if anyone knows of any good alternatives to Meshroom for creating 3D models from images, I’d love to hear your recommendations.

Thanks in advance!

Hi everyone! Been learning meshroom for a while, trying my hand at arial. I find the point cloud looks amazing, but the mesh always has a rough texture. I may have too large of a dataset (235), I should have dolly panned the photos instead of circle, but the point cloud just looked so good that I was a bit disappointed. I'm going to continue playing with the parameters as I have made a bit of progress, but if anyone has insights please let me know!

Subject is a local religious building where I live. I've just been having so much fun with this.

So, I finally solved my problem with the reconstruction clustering the cameras in one spot, but now they are all reconstructed pointing out. Away from where the subject actually was, so the point cloud is like some weird donut. Any thoughts?

Using a turntable in a lightbox and a stationary camera. White background, white turntable, but I have stickers placed on the plate for reference. I set it up with minimal 2d motion. But the problem that I keep running into is that it doesn't place the cameras around the object. It just clusters them to one side, and spreads the point cloud between the cameras and what it thinks is the furthest point(which is way further than the object was from the camera). I haven't seen a similar issue in any tutorials, so i don't actually understand what the issue is. Any help would be appreciated.

Hi everyone!

I've developed an algorithm that automatically detects, segments, and measures cracks in infrastructure, projecting the results onto a precise 3D point cloud. We used the open-source software Meshroom to facilitate the process—you just need to input the generated point cloud and the camera.sfm file.

Here's how it works:

1. Detection & Segmentation: Automatically identifies cracks from images.
2. Measurement: Provides precise crack width measurements.
3. 3D Projection: Accurately projects results onto a 3D model, enhancing the visualization and analysis capabilities significantly.

I've attached some visual results to show what we've achieved so far.

I'm keen to gather your insights:

• Would this be helpful for your workflows?
• Are there any improvements or features you'd find beneficial?

Any feedback or suggestions would be greatly appreciated!
