This is a recording of a webinar held 14 October 2021
This was the fourth instalment in our underwater mapping webinar series. Our speakers were Dr Mark Shortis and Dr Petra Helmholz.
Dr Mark Shortis is an Honorary Professor in the School of Science at RMIT University. He has had more than 40 years of experience in research and teaching associated with close range photogrammetry, with specific application to camera calibration, optical metrology and underwater measurement.
Dr Petra Helmholz is Senior Lecturer in Photogrammetry within Spatial Sciences at Curtin University where her work includes teaching and research. Current research interests focus on application driving research using Photogrammetry in the areas of health, agriculture, heritage mapping and engineering as well as underwater photogrammetry.
Underwater photogrammetry is used for a variety of applications, such as mapping reef ecosystems, assessing the population distributions of indicator fish species, and heritage recording of archaeological sites. Image capture may be based on single or multiple cameras mounted on UAVs, diver operated systems, towed bodies and drop video systems. Calibration and validation techniques are varied, depending on the expected or required accuracy of measurement. This presentation provided an overview of the various approaches to calibration, the impact of stereo-camera system configuration and highlight some applications of fish measurement and species identification.
