What do we mean by 3D?

Benefits of 3D• Easy overview

• Fast, shared understanding

• Shareable

• Impossible views

• Context

• Measurement• Properly assess condition.

• Comparison• Year-on-year change.

• Pre/post install

• As-built records

• Pretty Pictures

3D Enables the Future

• The future is AI powered autonomous survey.

• 3D perception tells us where things are, and what size.

• Machine Learning tells us what we’re looking at.

• Planning tells us how to capture the data we need and where

to go.

• Autonomy will be a gradual thing

• People won’t suddenly be replaced by robots.

• But it will happen eventually!

What is Artificial Intelligence?

•Perception

•Memory

•Reasoning

•Planning

•Prediction

AUV 3D – Live Scaled 3D

• Hardware and software for live 3D vision.

• Cutting edge sensors and compute.

• Evaluation trials Summer 2018.

IVAS – Intelligent Video Analytics for Subsea

• Deep learning to extract meaningful information from video.

• Repeatable, reliable video analysis.

• Exploiting cutting edge research.

Getting the Job Done

• If measurement and visualisation is the job for 3D, what’s the job for IVAS?

• Automating the boring and error prone.

• Generating actionable data.

Putting it all together – Autonomous Survey

Putting it all together – Autonomous Survey

Summary

• 3D isn’t just pretty pictures.

• Better measurement = lower risk.

• Rovco offer high quality 3D as an add-on to our normal survey

and inspection work.

• 3D isn’t just the tech.

• It’s about capturing the data efficiently

• It’s about delivering the data to the client.

• 3D from vision gives freedom to meet detail requirements.

• The process, and cost, that’s right for the job.

• The future is not just standard video survey.

• We’re gearing up to trial advanced AI now.

• Check out our models online, or at our stand.
