Abstract:
Stereo measurement has become a widely accepted tool for accurate and non-extractive assessment of fish populations. This presentation will introduce the basic concepts for using stereo measurement underwater, including requirements for building and calibrating underwater stereo camera systems. Precision and accuracy of underwater stereo measurement will be explained, with particular focus on camera configuration. Basic survey techniques of baited remote camera systems and transects will be introduced with examples. SeaGIS software packages for stereo calibration and measurement will be discussed.
