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
COLMAP-CL, a fork of COLMAP that can be run without an Nvidia CUDA capable card.
Free and Commercial Photogrammetry software review: 2020 [with minor updates in 2021]
It's been a few years since I've done a review of all the software I've tried. It's time to update that, with more free software, and the commercial (paid) software I've been trying out. I was trying to find a way to include a sort-able and filter-able table, but that requires a business plan apparently,... Continue Reading →
Photogrammetry Testing: 3DF Zephyr 5.0
I’ve covered 3DF Zephyr before, both the free version, and the professional version. Today 3D Flow released version 5.0, which claims significant speed ups and quality improvements, so I thought I’d run my standard dataset through it. I'm using the 14 day trial version of Lite. The free version is still available but limited to... Continue Reading →
Upgrading the arduino photogrammetry to use InfraRed LEDs to trigger the camera
I've detailed my Arduino photogrammetry setup, first here when it just used my phone, then here when I cludged together a physical trigger in the form of a servo motor. That worked really well, and I've made a bunch of models with it that have come out absolutely superb. However, to get the servo motor... Continue Reading →
Transferring textures from two halves to a whole (using Maya)
Retexturing from two seperate scans using Maya.
Transferring textures from two halves to a whole (using Blender)
Using a scan in two halves to re-project a texture onto a new mesh, using Blender.
Aligning and merging two halves of a scan: CloudCompare
This post will show you how to align a scan in two or more parts using CloudCompare. Or there's a video tutorial. Ideally, when you scan an object with laser scanning or photogrammetry, you want to get the whole thing in one go. With photogrammetry, that might involve what I've seen called the 'void' method...
