A guide to 3D Reconstruction for Archaeology

https://www.youtube.com/watch?v=MI_uBy8Sw44 I made a video explaining how I usually make 3D models. Please do check it out and let me know if there is anything you would like me to talk about in part 2.

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

http://www.youtube.com/watch?v=8dW4L9KaQxI 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 …

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 …

Photogrammetric Model Made With Iphone 4s

http://www.youtube.com/watch?v=Rhxqcs5RqDE I've experimented before with using my Iphone to create Photogrammetric models (not through the app, just taking the photos and running it through the Windows version of 123D Catch), with interesting but not perfect results. The other day however I found myself with a nice complete in situ sheep skeleton and no camera, so …

A Theoretical Approach to Photorealistic 3D Video: the Future of Film and Gaming?

Generally I am not a big fan of theoretical issues, especially when it comes to something as practical and visual as 3D modelling. This however is something I cannot really experiment with practically (or within an acceptable time frame), so for now it has to remain in the grounds of theory. It is also not …

Textures in Photogrammetry: How They Can Deceive Us

One of the advantages I find in Photogrammetry is that unlike other methods such as laser scanning and regular 3D recording, the results are photorealistic. The models seem natural and precise due to the textures that are associated with the points, and aesthetically it is much more pleasing. In addition to this it is amazing …
