Palaeontologist: Dinosaur Footprints – Biomechanics – Simulation
Since I first started getting into Photogrammetry in a serious way, with my 2012 paper on using Bundler and PMVS, and throughout much of this blog’s life, I’ve been a massive proponent of free and open-source photogrammetry software. For years I used COLMAP, and then Meshroom. The latter was particularly good, offering a full pipeline... Continue Reading →
I’ve been testing out instant-ngp recently, it’s an open-source software from Nvidia that generates neural radiance fields. That’s a 3D representation of an object that is fundamentally different from the points or verticies and faces we may be used to. Rather than representing an object through 3D coordinates, connections between them, and colours (i.e. vertices... Continue Reading →
I saw recently that COLMAP had received an update to 3.7 in late Jan '22 (I'd previously tested 3.6 a year or more ago), though after a quick, unscientific trial, I didn't notice any particular changes to UI, workflow, speed, or quality of final model, so I didn't think it was worth a blog post....

I was contacted just before Christmas by Alan Broun from Beholder Vision, asking me to give it a twirl and write about my thoughts. Beholder Vision, https://beholder.vision/, s a cloud-based photogrammetry solution. That means everything runs in the cloud, rather than on your local hardware. I tend to avoid the cloud-based solutions, because I live... Continue Reading →
Using "color match" in photoshop to make two photogrammetric models made under different lighting conditions, more consistent.
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 →
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 →
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 →
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 →
I test out the Surface Pro X as a replacement for my Surface Go. I try out x64 compatibility too, using the latest Windows Insider preview.
