摘要

In the throwing disciplines of track and field sports disciplines the release velocity and the release angle are crucial factors of the throwing distance. Based on a typical three dimensional video measuring unit a method has been developed to provide these parameters within short-time as feedback information during training. With a newly developed mix-unit two synchronous video signals are composed to one signal with a shift of one half frame. Data acquisition (including live-capturing) and processing of release parameters during the final phase of the throw are realized with a specific analysis program. Feedback information can be presented within ten to twenty seconds after the throw.
