Abstract
It is disclosed a method, and a system (30) capable of localizing ball hit events on a sports court. From on acoustics data acquired (22) of ball hit events by individual distributed sensors or microphones, ball hitting patterns are identified (24) in the data from each individual sensor. Based on the identified ball hitting patterns and geometric constraints of a sports court and the distribution of sensors, ball hit events are detected (26). The localization of the detected ball bit events is determined (28) based on the geometrical constraints of the sports court and the sensor distribution. The system has a number of advantages of which some are that it is cheap to install, it is non-invasive, and that it can easily be extended to provide higher precision of ball hit event localization.
