Although underwater swimmers video recordings are widely diffused, swimmers kinematics is usually reconstructed only on a single sagittal view. Some authors performed a 2D kinematics analysis of the front crawl by means of multi-cameras underwater acquisition systems, relying on manual digitization of specific features’ position. Thus in this study an automatic and repeatable method to assess 3D kinematics of front crawl swimming is presented. This combines both the Calibrated Anatomical Systems Techniques technique (CAST) [1] and a semi-automatic feature tracking technology.

Abstract

Although underwater swimmers video recordings are widely diffused, swimmers kinematics is usually reconstructed only on a single sagittal view. Some authors performed a 2D kinematics analysis of the front crawl by means of multi-cameras underwater acquisition systems, relying on manual digitization of specific features’ position. Thus in this study an automatic and repeatable method to assess 3D kinematics of front crawl swimming is presented. This combines both the Calibrated Anatomical Systems Techniques technique (CAST) [1] and a semi-automatic feature tracking technology.
