Meshroom CL – The best free photogrammetry software now works without Nvidia
A little while ago I wrote about COLMAP-CL, a fork of the original project re-written so as to remove the reliance on CUDA, and therefore Nvidia GPUs. Now, from the same source, OpenPhotogrammetry on Github, comes Meshroom-CL. It's still in pre-release, at version 0.7, but I gave it a run through on my work iMac... Continue Reading →
Updated batch script for Meshroom 2021
This is an update of a previous post, because updates to meshroom broke the previous scripts. There's two main changes to Meshroom that have occured: Instead of Meshroom_photogrammetry.exe, you now call meshroom_batch.exeYour scene must have a publish node after the final node. Here's the updated script, and it should be commented appropriately: :: meshroomCMD.bat ::... Continue Reading →
REMBG – a phenomenal AI-based background remover
I've previously detailed my process for removing backgrounds from non-ideal photogrammetry data sets, using Photoshop and it's pretty neat object selection tool. The result of removing backgrounds from images is that you can use the 'void' method, without needing a full photoshooting studio. For instance, I have a lightbox, but it's only good for small...

Photogrammetry testing [Commercial] – ContextCapture
ContextCapture is Photogrammetry software from Bentley. In fact, it is a pretty comprehensive set of tools for photogrammetry, laser scans, meshing, GIS, etc. I was contacted by someone from Bentley, who asked me if I'd like to give it a test run. I was set up with a trial, but aside from that I've not... Continue Reading →
Adding thickness to your scans for 3D printing. Or… Making 3D surfaces into solids.
I scan a lot of 2.5D things. That is to say, 3D, but only a surface. Think dinosaur tracks, like this: One of the problems you can come across is if you want to 3D print something like this, it needs thickness. Visualization can also be helped if there’s context for the edges. I’ll outline... Continue Reading →
Macro photogrammetry – digitizing small details
A lot of the photogrammetry models I make, and that I generally see online are of decent sized objects, or even large buildings and terrains. But as long as you can take a decent photo of something, you can digitize it. A while ago I tweeted some nice Macro images of a fossil fish specimen... Continue Reading →
Epic games buys RealityCapture developer
This is very exciting news I came across on shuttercg.com - Epic games have acquired Capturing Reality, the developers of Reality Capture. This is a pretty big deal, I think. Reality Capture was by far, both the quickest and best quality photogrammetry software in my testing. However, their pricing model has been pretty ridiculous, either... Continue Reading →
Meshroom 2021.1.0 – What’s new, and what parameters to tweak
Last week the binaries for AliceVision Meshroom 2021.1.0 were released. I’ll take a look at what’s changed since the last time we took a look at Meshroom. Meshroom 2020 and texturing. The last time I posted specifically about Meshroom, it was version 2019.2. I didn’t make a post about 2020.1.0 mainly because texturing broke. Previously... Continue Reading →
Photogrammetry Testing: COLMAP-CL – a game changer for those without an Nvidia card
