THE
development of Abiss-MetriCam generated a
number of research projects, both academic and commercial,
and resulted in the publication of several journal
papers, conference
papers, articles,
invited
lectures, posters
and a PhD. The programme comprised:
Original
Abiss development
Field testing of Abiss
PhD research project using Abiss
The development of Abiss-3D
Writing of MetriCam and the
Automatic Seabed Video Analysis project

Original Abiss development
Abiss
was developed by Dr
Derek Pilgrim at the University of Plymouth,
UK, to facilitate the acquisition and measurement
of images of the seabed, and natural and man-made
objects lying on the seabed. Particularly, it
addresses the major problem associated with
the analysis of ROV photographs of the seabed:
varying perspective caused by unknown angle
of view, unknown camera altitude and, generally,
unknown camera zoom. Abiss comprises
a structured lighting system (diode laser array)
and a software package, Benthic Imager
(now MetriCamsoft),
to analyse the seabed images. |

PhD
research project using Abiss
Dr David Parry used the Abiss system in benthic
surveys of Plymouth Sound, England, and Loch
Creran, Scotland, during the research programme
for his PhD thesis "Quantification
of marine megafaunal distribution patterns
using a remotely Operated Vehicle",
(see
PhD abstract).

The
development of Abiss-3D
This project was undertaken in collaboration
with, and supported by, QinetiQ. Research student
Sid Remmer demonstrated that it was possible
to define the dimentions of curved surfaces
such as a cylinder, sphere or cone using a 16-spot
Abiss-style array (see
photographs). |

Writing
of MetriCam and the Automatic Seabed
Video Analysis project
Experience of Abiss and its associated
software package led to the writing of a completely
new and improved programme, MetriCamsoft
(see
details). This system was field tested and
further improved during the research programme
Automatic Seabed Video Analysis, a
collaboration between the Plymouth Marine Laboratory
and Seabed Informatics Ltd. |
