Camera Angles: Tips on Photogrammetric Recording of Finds Part 2

In part one of this guide I tried to explain the uses of different coloured backgrounds to achieve good Photogrammetric models of small finds. This however is only one of the things to considered, and hence today I’d like to talk a bit about camera angles. The way I see it there are two parts […]

8 Reason Why We Should Be Using Photogrammetry in Archaeology

If you are an archaeologist you should be using Photogrammetry because: It is easy to use: Unless you are dealing with something extremely large or extremely complex, Photogrammetry has an extremely high success rate. When it was still based on camera calibration, complex calculations and precise measuring was necessary, but with more modern programs often […]

Back or No Back: Tips on Photogrammetric Recording of Finds Part 1

Photographing finds in order to make a 3d model can be a quick and easy process, but on a few occasions you will find that even the most accurately placed camera positions can create blurry or incomplete models. There are many reasons for this problem, and even with all precautions taken there is no 100% […]

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 […]

Community Engagement and Online Galleries

One of the main aims of the 2013 excavation at Caerau was to engage the community as much as possible, so that this amazing hill fort would become part of the people living in Cardiff and particularly Ely, rather than something separate from them. During the four weeks spent on site hundreds of school children […]

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 […]

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 […]
