Tracking of movement under water is still in its infancy. Difficulties include the designing experimental systems that are able to account for the distortion of dense media and the electrical insulation of the experimental apparatus. We propose a simple and inexpensive underwater system which combines the use of GoPro cameras and camera space manipulation (CSM) algorithms for the tracking of movements under water. A comparison of the GoPro cameras to standard computer vision cameras was performed to verify the effect of fisheye lens distortion on linear and non-linear CSM algorithm. Finally, calibration under water was performed using a linear CSM algorithm obtaining errors comparable with measurements obtained by standard cameras outside of water.
