[TeachingTech] There's a video featuring OpenScan Mini that nicely demonstrates the workflow, hardware, and processing methods for converting small objects into high-quality 3D models. If you're interested but don't know where or how to start, this video is a great guide.
We've covered the OpenScan project in the past, and the project has come a long way since then. [TeachingTech] shows how to scan many small, complex objects, including keys, to create 3D models with excellent dimensional accuracy.
[Thomas Megel]The OpenScan project is a DIY project, at its core an automated camera rig that takes a series of highly controlled photographs. These photos are used in a process called photogrammetry to generate 3D models from the source images. The OpenScan hardware platform plays a vital role, as the quality of the source images is critical to achieving good results.
Once you have high-quality images, the photogrammetry process itself can be done in a variety of ways. You can also feed images from OpenScan to programs such as Meshroom, or use the optional cloud services provided by OpenScan (originally created as an internal tool, but now available as a convenient processing option) can also do.
It's great to have a video that shows how the entire workflow works, highlights the quality of the results, and compares it to other 3D scanning methods. We've previously talked about 3D scanning and what it does (and doesn't) do well, and the OpenScan Mini's results are impressive. It may be limited to small objects, but it does a great job with them. See it all for yourself in the video below.
