Hi, I'm looking for some help when merging two different RealityCapture files with control points:

So, I am trying to make a 3D model of an object and I have followed a youtube tutorial for doing this where I take photos of two sides of the object, seperately align each side, create a preview mesh and mask, and then align both together. This has worked successfuly for one of my objects.

However, for another object the photos of both sides did not align properly to begin with. So, I have been using control points to make them align and this has worked, producing new components that have all of the cams aligned.

Now, I want to align both sides together (I have two seperate RealityCapture files with control points). However, whenever I try to do this, I lose the alignment created by the control points and the points split again into several mis-aligned components. I have exported the control points as csv files for both sides of the object, but this didn’t change anything.

Any advice on how to consolidate/set/finalise the properly aligned point cloud so that it can be merged with another point cloud that also has control points?

Thanks in advance! Let me know if you need anymore details

We are not able to get DJI Terra to function. Out IT department has tried a bunch of things to overcome this issue. Does anyone here have any experience with non functioning Terra and maybe some possible ways to fix this?

Hello everyone! I’m having a great time learning to use photogrammetry in Reality Capture. My primary goal is to capture trees (and, to a lesser extent, other assets like interesting rocks, textures, etc., although these aren’t for the SpeedTree portion). I plan to import these photogrammetry meshes into SpeedTree (tree modeling software), where I can refine them into (hopefully low poly) assets for Unreal Engine 5.

I’m looking to spend £200-£400 on a camera, but I’m not sure what to get as I’m not sure what’s important in terms of photogrammetry. According to my friend resolution is the most important feature, but aside from that I’m not too sure, any advice appreciated!

Hi there,

I'm trying to 3D scan some jewel beetles and specific body parts of these beetles to print them out as moving parts to make robots. I tried scanning using an Artec Leo (horrible resolution), so I'm trying out photogrammetry. I have the basics of the setup, and can understand the physics of it (I have a macro lens DSLR, strong lighting), but I need to figure out how to build a setup to take the pictures from a fixed distance from every angle around the object.

We use photogrammetry at work to produce models of large structures, part of out workflow requires us to pull custom defined ortho planes (orpoho facade).

We currently use Pix4D but software is endlessly changing so I'm wondering if we have missed anything.

Out of interest, is there anyone on this sub who does consultancy services or may even be looking for a job? If anyone is interested is discussing a job, feel free to drop me a PM but they need to be UK based.

Edit to add - A significant issue is some of what we do is the need to process sensitive data. Therefore Chinese and Russian software would be a problem.

Hi everyone,
I have a task to build an IT solution that will be used to calculate the volume of materials in the stock.
And I want to ask if photogrammetry will be a way to solve this problem.
If yes could you please recommend some resources, I am still discovering the field,
The image is an example of the shape that I want to calculate
Thanks in advance

I came across this photo from a recent Unreal event showing what looks like the latest version of Quixel’s photogrammetry rig?

Does anyone know what the new box attached to the rig is for or what might be inside? Earlier iterations only seemed to have the ELB 500 battery pack, but this version seems to have more going on.

Also, there’s a visible laser beam coming from the rig, projected onto a dark pillar. Could this be for alignment or calibration?

Greetings !

I'm currently improving myself on QGIS (self-learning at my workspace) and I wonder how usefull it could be to learn photogrammetry with drone to enhance this ecosystem. Lets add I'm not even a newbie regarding drone and photogrammetry, but more a layman who has zero knwoledges about all this subject, so I don't know if it's a dumb question. Is it something which could be useful ?

Nowaday, I work on photovoltaic projects and I use QGIS and AutoCAD to design power plants. I was thinking maybe photogrammetry could be good to scan a terrain in details, with all the subtilities, trees size, buildings etc. but on the other side, in my country, I already have access to quite accurate DEM (1m res) and the country LIDAR scan is ongoing, so I'm afraid photogrammetry may be an overkill.

If some of you use similar environnement, I would be glad to read you about it.

Have a great day !

We've been trying to come up ideas for a GCP that can easily be detected on thermal images. Right now our thermal cameras include the Micasense Altum and FLIR VUEPro R 13mm. The custom GCP we've made uses aluminum sheet metal and flex seal. It kinda works but we'd like something more.

Does anyone have ideas for what materials we could use to make a GCP that is really noticeable in thermal imagery or a company that produces GCPs for thermal imagery?

Hi, I joined the group today and wanted to share a section of my unfinished thesis. Although the experiment was conducted nearly four years ago, I haven't shared the results with any scientific community, and I believe some might find it interesting.The experiment aimed to explore the potential use of non-metric cameras for tracking the 3D movement of a spherical object using synchronized videos. I utilized two DSLR cameras (Nikon and Canon), along with Photomodeler software, Adobe Premiere Pro, and Google SketchUp for visualization.I'll include a link to the PDF of the experiment below. Looking forward to your feedback!

Good afternoon all

I have taken 255 images of CNR 6167 in Guelph, ON and am trying to make it into a 3d object. I downloaded meshroom, but I do not understand it well enough for the results I desire. I can render half at mediocre resolution but cannot render both together, and my scaling is off.

I am looking for either someone to render it and send me an obj file of the finished product, or to walk through what I am doing wrong.

Please let me know. Do not DM right away, I want to talk in public below first

Thank you

Hi all,
I have been working on photo-scanning different boulders, and have mixed results between different software. For now, I haven't used a drone, which limits the visibility from upwards direction, and thus there are inevitably some parts of the area that aren't properly visible from any photos. I've added a screenshot from RealityCapture below.

My experience from different software so far:
RealityCapture: Rather fast, seems to produce both HQ mesh and textures. Has though some gaps, that are covered by other software (f.ex. the bulge on the right side of the screenshot).

Meshroom: Seems to produce similar quality than RealityCapture, but process takes much longer.

Colmap/Glomap: SfM part really quick, Glomap especially produces superior sparse point cloud with areas mapped that have been ignored by the aforementioned. The meshing and especially texturing (with mvs-texture) phases though seem to be of subpar quality. Am also planning to try out mast3r-sfm as a replacement for the SfM, but this seems to require relatively much effort, and given the subpar mesh/texture quality, maybe not worth the effort right been.

Have also been thinking about writing a Colmap/Glomap node to Meshroom to try to combine best of different software.

Does anybody have any other recommendations for software and/or have found some parameters that are especially important to tweak with?

I'm getting "okay" but not "good" results in Metashape using my old Olympus E-500 5-megapixel camera and an old Minolta 50mm film camera lens. If I were to step up to an inexpensive 24 to 36-megapixel camera with a decent prime lens, could I realistically expect to see a dramatic improvement in the quality and detail of my meshes?

Hello,

I work with MicMac software and as an output I can get the positions and angles of the camera. My camera is fixed to an aircraft and I know the rotation between the camera system and the aircraft reference. How can I get the aircraft's yaw pitch and roll ?

Thank you

Hi guys, i have a data of my hometown, it's osgb file create by ContextCapture, and i have convert it to obj file, i want to print it use my 3D printer, but i dont kown how to convert it to stl file.

I have search some method at google, just as using Blender to conver a DSM to stl, or convert a closure obj file to stl, but photogrametry file create from drone are nor very regularization.

P1 is my data, P2 is the result I want. Ps. P2 from Youtube @Rob Haskett

Do you know how to achieve this effect?？Thanks so much.

I built a texture with Metashape Pro from 16-bit TIFF images. I tried File > Export > Export Texture... and chose TIFF file but it went to 8-bit when I checked the file on Photoshop.

I there any solutions to export the baked texture to a 16-bit TIFF file?
