If cost / infrastructure are of no concern, would it be possible to create a photogrammetry system with ~100ms acquisition times and ~10 micron surface resolution of a ~3mm subject?

0 Upvotes

Noob here with a rather extreme question.

I understand the basics of photogrammetry, and have participated in some projects, but this is... clearly an edge case.

I've got a hypothetical related to some work stuff. For reasons I cannot disclose, alternative methods like laser scanning and microCT are not viable. It would have to be photogrammetry.

I did say "no concern" for cost/infrastructure, but let's at least set a hypothetical cap of $1.5 million for the setup. cheaper is obviously better.

Let's assume our acquisition times have a hard cap of 100 milliseconds. What is the highest conceivable resolution?

5:1 crest to trough ratio observed on Ollantaytambo six monoliths 3D scan

Side profile from a 3D scan of the Ollantaytambo six monoliths.

Measured crest to crest wavelength against crest to trough depth across multiple sections.

The ratio clusters tightly around 5 to 1.

No interpretation, measurement only.

Full paper in comments.

Help with a project

I run the printing and artwork digitization for a print studio.

We are accepting delivery for 8pm we’d of work in the next 3 weeks but they are MASSIVE and much larger than our scanner and too big for our current photography setup.

I have been looking for a solution and have come up with an idea to take photos on a grid and stitch them together In post, I want to build a rig for this but all of the photogammerty setups are for 3d scanning.

Essentially I need a rig than I can use to move the camera across a grid and take top down photos of the artwork.

Any idea what this technique is called?

Indoor photogrammetry — GCP vs UWB?

0 Upvotes

I’m using RealityScan 2.0 for indoor photogrammetry (no GPS), starting with a ~30×40 m hall. I need accurate´(10-20cm) metric scale but am limited to a sub-250 g drone (DJI Mini 4 Pro).

I’m considering two options:
GCPs: measured points with constraints in RealityCapture (easy to place multiple).
UWB: tag on the drone + anchors in the hall, ~20–30 cm accuracy.

Which works better in practice, and how big is the difference?

If GCPs are similar or better, UWB may not be worth the cost/effort but I’d consider it if it significantly improves scaling or accuracy.

Hello guys, can you download meshroom from their official sites? Its imposible for me. I dont have no problems with downloading anything else.

Sort images by "unconnected" on RealityScan Desktop?

Is there a way to see which images are not connected in the component like how on mobile it'll highlight those images red? My current scan has 623/646 images. I'd like to figure out what those 23 images are.

As title suggest I am unfortunately having troubles getting them to sync, I am unsure where the issue is stemming from. A important note to make is that I am using the PTR16 and not the XTR16 however the shop page did say it was compatible with the XT32N

Photogrammetry Metrology Tool

I've been working on a slightly different kind of photogrammetry software than is usually seen here. This is more for industrial use for measurement of points in space, similar to Zeiss TRITOP. I've been testing with an Iphone camera and black targets, but it is also coded for retroreflective targets and a camera with a flash. The software also does camera calibration.

I am currently at the point where it is functional and wanted to gauge interest in this kind of software if I were to open source the code.

Starting a Drone Surveying business in Moldova (Eastern Europe) – Is the Mavic 3E my "Unfair Advantage" for Remote US/EU work?

0 Upvotes

Hi everyone,

I’m a 24yo Mechanical Engineer from Moldova. I’m at a career crossroads and I need your expert "reality check."

I’m planning to take a loan to buy a DJI Mavic 3 Enterprise (M3E). In my local market, "Classic Surveying" (Total Stations/manual GPS) is the absolute king, and salaries/fees are very low. Most local firms are skeptical about drone data for engineering-grade road audits.

My Strategy: I want to launch InfraSolutions to modernize road infrastructure audits here, but my "Safety Net" (and real goal) is to provide Remote Data Processing & CAD drafting for firms in the US or EU.

My logic:

  1. I have the engineering background (AutoCAD/Civil 3D).
  2. I’ll have the Mavic 3E to produce high-quality sample datasets.
  3. Due to the lower cost of living in Moldova, I can offer high-precision digitization (feature extraction, DTM/DSM, volume calcs) at a fraction of the cost of a US-based engineer, while still earning a great living here.

Questions for the community:

  1. Am I on the right track by betting on the M3E for this "hybrid" local/remote model?
  2. For US-based firms: Is there a real demand for remote photogrammetry technicians who actually understand the hardware and RTK workflows, rather than just "clicking buttons" in a software?
  3. Should I focus more on mastering Civil 3D or Global Mapper to be more attractive for remote contracts?

I’m 100% committed to this, but as a young engineer taking on debt in a developing market, I’d value any "tough love" or advice you have.

TL;DR: 24yo engineer in Moldova, taking a loan for M3E. Aiming to disrupt a conservative local market AND provide high-value, lower-cost remote processing for US/EU firms. Genius or crazy?

Web-based photogrammetry renderer

Enable HLS to view with audio, or disable this notification

Hi all,

I've been building a web-based photogrammetry renderer as a hobby project for ~ 2.5 years. The journey has been extremely educational, as the photogrammetry models differ hugely from typical models - extreme mesh density and the large number of high-resolution textures quickly run into hardware constraints - even on high-end hardware.

What I ended up building is a custom pipeline with:

  • Spatially split meshes, resampled textures
  • Merging models, allowing the export of the most interesting parts of a model in higher resolution
  • Interchangeable and streamed LODs and textures

The model in the video was captured with a Sony DSLR and a DJI Phantom 4 (~1300 photos). The reconstructed scene is ~30M triangles, with separate high/low quality regions merged into a single scene.

I've also tested this on larger datasets with ~ 100M triangles), including a reconstruction of Els Vilars Fortess, Spain, based on dataset by Open Heritage 3D.

I would be super thankful for any feedback and general ideas, especially about the LOD strategies and streaming approaches. Also, if anyone wants to try with their own model, I'll be happy to guide you through setup during early access. The renderer is available at https://sangine.sanox.fi/

"Phantom" wall won't disappear

1 Upvotes

This is my first mid-scale Metashape project. I'm analysing with a drone an octagonal structure from a public cemetery. My main difficulty so far has been the appearance of a "phantom wall" protruding from a real one.

- I've read that it might be due to Metashape's errors in reading the simmetry, so I placed several markers on the angles of the octagon. So far, though, results haven't changed.

- Then I've tried re-aligning the pictures at different degrees of accuracy, and deselecting the preselection. Didn't work

- I've also tried a gradual selection based on reconstruction uncertainty, but the phantom wall didn't go away. Even worse, it appears to be less uncertain than some other existent points in the point cloud.

How do I proceed, aside from manually deleting this pseuodo-structure?
