OpenScan3 Firmware: An Architectural Overview
An overview of the architecture behind the OpenScan3 firmware, explaining core design decisions, abstractions and how different parts of the system fit together.
Recap of 2025 Intro 2025 has been quite a ride. It has been almost eight years since I started tinkering with 3D scanning, initially just trying to understand how photogrammetry works and how far y...
Optimizing 3D Scans: What is the right shutter speed?
TL;DR: We tested the OpenScan Mini to determine how shutter speed impacts 3D reconstruction quality. We found photogrammetry is surprisingly robust to exposure variations. In our test, there's a w...
Optimizing 3D Scans: How Many Photos Do You Really Need?
TL;DR: Is more always better? When it comes to photogrammetry, the clear answer is no! We performed tests, which align with our experience, showing that there is an optimal number of images for tur...
Testing the influence of JPEG quality on the 3D scan results
TLDR: With high contrast surface preparation of the object, JPEG quality can be reduced to under 20% without any noticeable influence on the 3D mesh. Furthermore, the experiment indicates that the ...
