The hammer throw in athletics has been the subject of published research since the 1980s. This has focused on case studies of individual athletes or small cohorts and has identified a number of key performance indicators such as the speed profile of the hammer during the wind-up phase. To use these key performance indicators with current athletes a bespoke analysis tool is required for frequent data collection. An unobtrusive two cameras system was proposed and a non-standard planar calibration method that allows the safety cage to remain in place was designed. The performance of the non-standard calibration method was compared to the standard calibration method using simulated data. The non-standard method was found to be suitable when intrinsic camera parameters were not recomputed. The method is a suitable alternative for volumes that cannot easily be accessed with a calibration object or volumes that are too large for practically sized calibration objects.
