Using a scan in two halves to re-project a texture onto a new mesh, using Blender.
Transferring textures from two halves to a whole (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...

Photogrammetry: Does shooting RAW or JPG make a difference?
This is one of those questions that I see cropping up regularly in discussions online and off; Should I shoot and process RAW photos, or will I get the same results with out-of-camera JPGs? There is absolutely a school of thought among photogrammetry practitioners that everything should be absolutely top-quality: Prime lenses, shooting in RAW,... Continue Reading →
Alicevision Meshroom 2019.2.0 – best settings (that I use)
I covered Meshroom back when it was version 2018. Shortly after, I wrote about trying out all the settings. It's been over a year and half since then, and in that time Meshroom has become my default photogrammetry software. I've got into a habit with changing the default graph, so wanted to share the settings... Continue Reading →
Photogrammetry testing: Regard 3D
You can find links to all my other tests/guides here. Regard 3D has been around for a while now. I included it in my 2017 photogrammetry roundup, and version 1.0.0 was released in march 2019, but I’ve never actually run through it on my blog, so here goes. Regard 3D uses openMVG as the backend... Continue Reading →
Photogrammetry testing: OpenDroneMap

Extending my Automated Arduino photogrammetry setup to include a DSLR
Extending the arduino photogrammetry setup to turn the turntable by an arbitrary amount, then trigger an android phone and a DSLR, then move the turntable again and repeat.
The best free software for editing and cleaning (decimating and retopologizing) meshes and 3D data [2020]
Working with photogrammetry, laser scanning, and all the other techniques I dabble with/intimately rely on, I generate a lot of 3D data. For the most part that data is usually very high resolution, and often quite noisy and in need of cleaning up. I want to detail here some of the software I've come across... Continue Reading →
Automating photogrammetry – 3D printing, an Arduino, and an Android phone
[edit] - I later built on this post and extended the setup considerably here. Photogrammetry is awesome, and there’s a whole bunch of papers and software out there that mean you can do it for free. But taking 100’s of photos can be a pain. I’ve been eyeing up ways of automating this for a... Continue Reading →
The new ‘select object’ tool in Photoshop 2020 is a lifesaver for photogrammetry
Using the new 'Select Object' tool in photoshop to very quickly clean up photogrammetry data.
