I have been using the process of photogrammetry for nearly 4 years now, and it’s slowly moving from the realm of what I originally thought of as witchcraft, to the realms of an exacting process, that, if not planned and carried out correctly, can bring a whole world of hurt. I am personally, not one to rely on a process, without trying to understand the principles and the technology behind it.
From the outset of forming this company, we have always had a vision of developing a workflow between reality and digital and back again, but when we first looked at this, certain technologies available were still at a relatively early stage. laser scanning and 3D printing has developed over the last few years so that we can now offer a service that combines very traditional techniques with the latest technologies.
With everything we do here at DTM Technologies I think a Blog section is well overdue. So, to start things off I thought it would be good to give a very brief introduction to the services we offer and how best they can be used in industry. Over the next few weeks we will add more content, detailing specific project details, for whom it was carried out (where we can) and for what purpose, we will also discuss our specific services in detail.

Photogrammetry, so what is it? What if I told you that its origins date back to the grand old master himself, Leonardo Da Vinci and also Albrecht Duerer, in the 1400 and 1500’s. Perhaps not in the same sense as we use the term today, but they were the first to use mathematical science to determine perspective within their drawings. From this developed the use of mathematical principles to determine the co ordinates of a point in 3d space from two or more images. Imagine that but using modern digital cameras and the power of computers to match every pixel from two different photographs (pairs) and then using hundreds of photos over hectares of terrain.

This is a collaborative monitoring and technological advancement project between SEACAMS (Bangor) and DTM Technologies (www.dtm-tech.co.uk).The project began in late January 2015 and involved the removal of large quantities of sand, vegetation and humic material from the dunes. This has been done to encourage sand mobilisation from the beach through the main dune wall and in to the slacks behind, (more…)
