Palaeontologist: Dinosaur Footprints – Biomechanics – Simulation
**WARNING - this is a very niche rant** I'm quite a tech nerd. I enjoy gadets, and phones, and even writing software and addons. A big part of this is that I just generally enjoy interacting with my computer's operating system to get stuff done. I've been firmly embedded in Windows most of my life,... Continue Reading →
I've had a keen eye on Alicevision Meshroom since it's first major release back in... 2018? Development of the open source photogrammetry software has felt slow for the past few years, but just this week a new release was pushed out, 2023.1.0. Here's the official new feature list: Release Notes Summary Major improvements of the... Continue Reading →
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 →
Here's a script to reduce the processing of AliceVision's Meshroom to a single double click. Much as I did for COLMAP, (and here) I've put together a batch file that can just be dropped into a folder of photos and double clicked to run the full Meshroom process and produce a filtered, textured model without...

Given how insanely popular my 'trying photogrammetry software' series has been this year, I thought I'd round up what I've tried, what's worked well, and what hasn't. Obviously I gave each piece of software in my blog posts a go with a standard dataset. That photo set was not ideal - it includes photos taken... Continue Reading →
