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 …

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 …

Program Overview: Meshlab

When writing my third year dissertation a few months ago I analysed a basic method of creating photogrammetric models using 123D Catch, and when it came to discussing the later editing of the models the program I turned to was Meshlab. I'd originally come across this program when looking at the Ducke, Scores and Reeves …

Glastonbury Ware Pot – Ham Hill

http://www.youtube.com/watch?v=DB4hfNxk1QA&feature=youtu.be This is one of the first attempts I made with Photogrammetry, and probably one of the ones I am most happy with. It is a beautiful pot found during the 2011 excavation, and that was glued together to show how it would have been prior to destruction. I made the model using around 60 …

Potential Method to Emphasise Inscriptions with 123D Catch?

Although this requires much more work and more tests with different objects, it could be a somewhat interesting method to better distinguish inscriptions present on coins or small object. The picture above is of a Medieval lead stopper or weight found at the site of Caerau, Cardiff, which has been made into a 3D model …
