A Survey of Spatial Measurement Tools for Micro-ROV

Andy Goldstein, Director of Software Development, VideoRay LLC

Surveying is the science of making quantitative measurements in order to determine and document the spatial positions and geometric relationships of details of interest. There are several technologies which can be deployed to make underwater spatial measurements. These include GPS (at the surface), acoustic ranging systems, acoustic doppler velocity logs, tether positioning, and photogrammetry and dataset mensuration.

Micro-ROV provide significant accessibility advantages relative to their larger remotely operated brethren. Unlike free swimming untethered vehicles, high bandwidth zero latency data is available to the operator. The small size which affords micro-ROV many of their advantages constrains the data acquisition and positioning instrumentation payload size.

An overview of the various measurement technologies available for deployment on small platforms will be provided. A basic explanation of the physical measurements being made by each system will be given. The strengths and weakness of each technology, as well as the suitability of several commercially available systems on micro-ROV will be discussed.

Andy felt the call of the sea at an early age, and dreamed of becoming some kind of cross between Errol Flynn and Richard Baseheart. Earning degrees in Computer Science and Materials Science Engineering he subsequently shipped out to Monterey California. Then after 12 years before the mast at Desert Star Systems as Chief Software Engineer he jumped ship and signed on with the VideoRay crew. In addition to his primary role as Director of Software Engineering, he is also responsible for the Academic and Research Program which is designed to stimulate external technological development.

Andy has 22 years’ experience creating software, 15 in the underwater industry. He has been the lead software developer on over 18 commercial products, 2 of which have garnered R&D 100 awards.
