The short answer is absolutely yes, the longer answer gets a bit more nuanced and we will have to dig into some details. So if you are concerned or just interested, stick around and feel free to share your thoughts. https://youtu.be/dwRMK9LzBBc?si=9GAau05hjsN3mcEJ Michael aka TeachingTech's video sparked quite some discussion about the Open Source nature of the OpenScan project. In my humble opinion, the video is very well-balanced and gives a great overview of the OpenScan Mini.

The release of the 2.6.0-alpha2 version of PrusaSlicer brings two new functions to the slicer that will be valuable additions to the photogrammetry workflow. Measurement tool The new measurement tool in PrusaSlicer 2.6.0-alpha2 "recognizes points (vertices), edges, circles and planes" and allows you to take measurements between these. Additionally, it allows you to pick a measurement and scale it – and the rest of the model along with it – to a desired length. Improvement for 3D scanning: A common nuisance with 3D models obtained through photogrammetry is that they do not turn out to scale. Th ..read more

tldr; Squidmar Miniatures released a great video, where they used the OpenScan Mini and the OpenScanCloud to scan one of their amazing miniatures. As the video is focusing on the results, I want to add some more technical details. Anway, the raw results already speak for themselves: If you haven't already seen it, please check out the entertaining video, where the same miniature got scanned and resin-printed again and again and again and ... https://www.youtube.com/watch?v=tp5p2nDnON8 Disclaimer: I provided a pre-build version of the OpenScan Mini free-of-charge, but besides a brief introduct ..read more

tldr; Till the end of September, you can get the new Arducam TOF camera on Kickstarter*, where you can now get the device for ~US$30 instead of US$50. What looks like a normal camera, is a depth sensor with a resolution of 240x180 pixel. This sensor is capable of capturing depth (3D) information with 30fps on a Raspberry Pi 4. Disclaimer: I got this sensor free of charge from Arducam. No money changed hands, and I am just doing some independent testing and evaluation. This post reflects my findings and opinion. An important note on Kickstarter and other Crowdfunding platforms: Before taking p ..read more

In my last blog I talked about the reasons for building an OpenScan classic with an RPi HQ camera. I also showed a bit of the increase in quality and sharpness of the scans. I sort of glossed over the whole project because I knew there was no way of including everything I want to talk about in one blog post while also keeping most of you reading until the end. That’s why, very early in writing the first blog post, I decided to make a series of articles. This is the second article, a deep dive in the pro’s and con’s of the 35 mm 1.6f Fujian lens! What constitutes a good photogrammetry imag ..read more
