Photogrammetry tutorial 12: How to preserve strike and dip or cardinal directions in your 3D model

Photogrammetry is a really nice and easy way of surface digitizing specimens in collections, but also useful in the field. Recently, Marie Attard, a colleague working in England, asked me to help with a project that deals with rock surface … Continue reading

Photogrammetry tutorial add-on: The consequences of optimizing a sparse point cloud

If you build a photogrammetric model following the workflow I suggest in this post, one of the steps is optimizing the sparse point cloud (tie point cloud) via gradual selection and deletion of points. Here’s why that matters. Below you … Continue reading

Photogrammetry tutorial 10: an improved method for mid-sized objects

Last December I was granted a sack full of money by the Senatskanzlei Berlin for the 2015 digiS programme. I’ll soon post more about that; what matters for this post is that I promised to mass digitize the rather unwieldy … Continue reading

Photogrammetry tutorial 9: Quick and dirty!

Over the course of previous tutorials and in my paper with Oliver Wings I’ve given quite a bit of advice on how to photogrammetrize objects properly. Today, I’ll address the other end of the spectrum: how to approach photogrammetry unprepared … Continue reading

Photogrammetry tutorial 7: multi-chunk project handling

In palaeontology (and many other disciplines) you often deal with specimens that you wish to capture in what I term “720°” – all around (360° around it for the vertical axis), and bottom and top, too (360° around the transverse … Continue reading
