Accuracy of 123D Catch

I always go on about how Photogrammetry should be used to record everything from small finds to entire sites, but just how accurate are these models? Are they good enough only for recording the objects as nice images or can they actually be used to gain more archaeological information? In essence, is it technology for […]

Using 123D Catch to Record in Situ Finds

If you have the pleasure of excavating a collection of finds rather than an individual one often one of the problems you will encounter is how to record it in situ. Some finds are delicate and may well break up once removed from the soil, while others may have been placed in a specific way […]

Reconstruction of St. Mary’s Church – Caerau

Here is my first video animation of Saint Mary’s church in Caerau, Cardiff. I made the model a few months ago of this beautiful church, which unfortunately is only partially standing today. It is based on a plan of the cemetery and a number of photographs I found from when it was still complete. Sketchup […]

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 […]

Photogrammetric Pottery Reassembling (PPR) Preview

This is part of a little project I’ve been working on, and which I’m hoping to write an article about soon. What you see here is a pot which was originally in fragments, and that I’ve reassembled virtually, in order to avoid having to glue it together. I used 123D Catch to digitise the pieces […]

Working on the Sphinx in 123D Catch

The other day I was talking with one of the guys at work and while chatting about Photogrammetry an idea came to mind. There are millions of photographs online taken by tourists who are visiting archaeological sites, and famous monuments like the Parthenon or the Pyramids surely have their photograph taken many times a day. […]

Introduction

Hi everyone, my name is Rob Barratt and I’m currently finishing my third year in archaeology at Cardiff University. During my time here I have developed a passion in anything computer related, and in particular with 3D modelling. As part of my dissertation I’m exploring the advantages of the technique called Photogrammetry in the archaeological […]
