Abstract
This paper describes a multi-camera system designed for capture and tracking of swimmers both above and below the surface of a pool. To be able to measure the swimmer's position, the cameras need to be accurately calibrated. Images captured below the surface provide a number of challenges, mainly due to refraction and reflection effects at optical media boundaries. We present practical methods for intrinsic and extrinsic calibration of two sets of cameras, optically separated by the water surface, and for stitching panoramas allowing synthetic panning shots of the swimmer.
