Abstract

The extraction and analysis of three dimensional tracking data relating to surface exploration of sessile marine organisms is of great importance for understanding the mechanism of surface colonization (biofouling). The knowledge of behavior can thus be used to develop tools for controlling and influencing undesirable impacts that arise as a consequence of the adhered organisms.

This paper describes a stereoscopic system currently in development for tracking barnacle cyprids and allows extraction of 3D swimming patterns for a common marine biofouling organism - Semibalanus balanoides. The details of the hardware setup and the calibration object are presented and discussed. In addition we describe the algorithm for the camera calibration, object matching and stereo triangulation. As practical result, several trajectories of living cyprids are presented and analyzed with respect to statistical swimming parameters.
