CSIRO Marine and Atmospheric research have developed a novel net attached acoustic-optical system to investigate the acoustic properties of deepwater fish (Ryan et al. 2009). The system attaches to the headline of a commercial fishing net which is then trawled through fish schools with the main objective of measuring the acoustic reflectivity (i.e. target strength) of individual fish. The system uses video, and more recently, digital SLR stereo pairs, to enable species to be identified and, using SeaGIS photogrammetric software, the key metrics of lengths, tilt angle and heading can be measured and directly associated with concurrent acoustic measures.

Software development for deep-water stereo GigE camera systems, automated image analysis and experimentation with deep-water stereo camera calibration stability.
