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 →
My wife recently upgraded her aging 2014 Macbook to a new 14" M1 Macbook Pro. Let me preface what I'm about to say with "I very much dislike MacOS and don't like using macs." Bear that in mind when I say I've never been more jealous of hardware. The MacBook Pro is beautiful, the screen... 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 →
A few months back I finally upgraded from my trusty Sony Nex-6 to the newer Sony a6400. I've only just got around to having the time to write a review. This 'review' will very much be a ramble about my feelings using the camera, not a technical, specialist review. If you want one of those,... 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 →
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 →
