Part 3 – Sources and Paradata

What is the first step in 3D reconstruction? Sources! How do we make sure the sources are precise and how can we assure people understand the accuracy of the final results? A look on metadata and paradata.

Part 2 – 3D Reconstruction Literature

A look into projects that have helped shape 3D reconstruction, from serious games to accuracy. Additionally, what are the main point of critique when it comes to modelling?

PART 1 – Visualisation

What is Visualisation and why is it important? What is the difference between Photogrammetry, Laser Scanning and 3D Reconstruction and how can you use this to your advantage?

Blog Reopened

Dear all, It has been a long long time since I last posted any new articles. It is safe to say that this blog fell into neglect and that I have been less than diligent in my duties as an open archaeology advocate. The reasons for this have been many. On one part I […]

Agisoft Photoscan

If you have been following this blog for some time, you will know that when it comes to Photogrammetric reconstructions I have always been a strong supporter of 123D Catch by Autodesk. I find that it is by far the easiest program to use, yet the results are still amazing. Recently they have released a paid […]

Photogrammetric Recording of Subvertical Pits

Up to now in my blog I have been trying to outline the uses of Photogrammetry in the two main areas of archaeology, recording and interpretation. Some things I have discussed were specific to preserving as much data as possible of an archaeological feature or object, by creating a virtual copy of it. Other posts […]

Bigger And Better: Photogrammetry Of Buildings

Photogrammetry is definitely the “new” thing in archaeology, slowly clawing its way into how we treat and record archaeological sites. As far as its potentials go though, there is still a lot of research to be done, in order to assess the uses that this technology has, but also the limits that we will have […]

Recreating Tower Of London Graffiti Using Photogrammetry

Last weekend I visited the Tower of London, which gave me a great opportunity to try out some of the Photogrammetry ideas I have had in the past few weeks. Apart from testing 123D Catch out on large monuments and entire palace façades, I decided (thanks to the suggestion of Helene Murphy) to try modelling […]

Emphasising Inscriptions Using 123D Catch

One of the most interesting projects I have been working on over the past few months has been trying to emphasise inscriptions on artefacts using Photogrammetry. The theory is that if the model is accurate enough it should be possible for a program to determine the different bumps in a surface and exaggerate them in […]

VisualSFM: Pros and Cons

I’ve been working with Photogrammetry for some years now, and although I use a great variety of programs to edit the 3D models, from Mehslab to Blender, when it comes to the actual creation of the models I have only ever used 123D Catch. This is partially due to the fact I now feel very […]
