Drones, Toys or Tools

Here at DTM Technologies, we have been involved in using drones/UAV/RPAS for nearly 3 years, which, I have to say, is not long in the grand scheme of things. We have been licensed by the CAA for commercial operations for nearly 2 years. In that time we have done a large amount of research into different systems, multirotors and fixed wing craft. The number of different systems (multirotors) on the market is huge. Most are advertised as easy to fly, fully automatic  and great for capturing anything you wish, from an aerial perspective. Although in some cases this is true, there is a lot more involved, especially if you are planning on commercial use.

When you are piloting ANY aircraft, you fall under the rules of the CAA, Civil Aviation Authority (in the UK), this applies to the hobbiest and commercial operators. There are rules you must abide by! failure to do so, will, at best, risk prosecution, at worst, risk lives!! Safety, safety, safety, It cannot be stressed enough, some of these machines weigh  multiple kilo’s and if something fails they will drop like a brick. Some craft which have more than 4 rotors, can, reputably can be landed safely when 1 prop, motor, speed controller fails, but this wont happen, right, because you spend more time checking and maintaining your craft, than the time its in the air. Thats right, maintenance, its a necessity, and it takes skill and knowledge to do it effectively.

So, if you think its still for you, lets look at the commercial side of things, we are not talking about your rig, or how well you fly here, just the ability to provide a professional service. Once a task and location has been agreed between DTM Technologies and a client, we will spend a number of hours just on researching the site for potential hazards,  creating risk assessments, looking at potential notifications if the area involves other air users, structures, roads, railways, etc, Oh, by the way, I wonder how many hobbiests do this, they should! the dangers are exactly the same!, anyway.

Photogrammetry & LiDAR – A Comparison

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 Concept to Digital model to 3d print to Moulding to Production run

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.

Introduction To DTM Technologies Ltd

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 & Aerial Surveying

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.
