Palaeontologist: Dinosaur Footprints – Biomechanics – Simulation
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 →
One year ago, on Christmas eve 2020, I posted about the Surface Pro X. I was very happy with it, except for one thing - the size. I ended up replacing the Pro X with the Surface Go 2 just a month or so later. My reasoning was that it was about as powerful as... Continue Reading →
Much as the popular view is that palaeontologists spend their days out in the dusty desert digging up fossils, the fact is most of us spend more time at a computer than anything else, and that goes doubly so when your research revolves around computer simulations. As such, a keyboard is probably one of the... Continue Reading →
Yeah, 'Academic' here is more of a stretch than usual... Having been locked down/working from home for however long it's been (12 months? 18 months? a billion years?], and having been using the same computer, tablet, and phone during this time, I've been getting antsy for a new device, particularly one that either fills a...

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 →
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...

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 →
