Photogrammetry Training

Why Photogrammetry?

Photogrammetry is a perfect tool to capture, digitally preserve the world around us, and to share what we love with others.

The models have many uses; dive briefings, archaeology, criminal evidence, scientific surveys – any project can benefit from preserving, recording and (if required) sharing 3D content with the wider public.

Anyone can acquire the skills to create a 3D model. You do not need expensive kit – a smartphone will do – and a laptop with Metashape loaded are all you really need to get started.

Underwater photogrammetry requires specific diving skills and just a basic action camera and lighting will get you creating 3D models.

Working with IANTD instructors Deep3D help deliver their Underwater Photogrammetry course for all underwater work. The course teaches the art and craft of how to create 3D models on land before practicing and refining the techniques underwater. A strong aspect of this course is managing the task and teamwork to ensure safe diving practice is adhered to.

This 2 day course is ideal for the qualified diver to upskill and start to create their own 3D models.

Training for Forensics

In July 2020 Simon co-founded Accupixel Ltd with José Martínez Rubio to support work with police forces and forensic users of photogrammetry.

As a result of this work (and thanks to a pandemic limiting classroom lead training) we have created a self-paced online training course intended to cover everything from the basics and foundations through to the Metashape Standard workflow.

For the more advanced user we cover the Professional edition in a second online course. This builds on the foundations of the Standard course and adds the wealth of features

The aims of the courses are to equip students with a thorough background and understanding of photogrammetry and the required photographic standards, with the Professional edition teaching everything from recursive optimisation to cylindrical DEMS and working with laser scan imported data. It is being used to train forensic collision investigators who demand a high level of both accuracy and repeatability.

The courses has been endorsed by none other than Agisoft – the authors of Metashape.

Why Deep3D?

Deep3D are at the leading edge of the application of photogrammetry. We have used everything from an iPhone for modelling land-based cultural heritage to using a housed SLR camera mounted to an underwater scooter to scan an entire shipwreck.

We come with a wealth of practical experience. Course students have included everyone from hobbyists to a British Antarctic Survey scientist wanting to use photogrammetry to measure the growth rate of sponges under the ice shelf.

Want to take it further?

Do you need to be able to scale and measure the model with confidence and accuracy? Do you need to understand how the 3D model relates to the real world and require embedded GPS data?

DEMs and orthophotos are perfect to record incredible detail. Do you need to create and maintain permanent records of how things were?

We regularly work media companies and archaeologists to deliver accurate 3D models and associated data.

Deep3D are currently working with law enforcement agencies to increase efficiency whilst improving the methods and techniques used to preserve evidence.
