Location-based entertainment centres, such as indoor playgrounds, are well-known for the use of plastic balls in ball pits as part of their entertainment. Furthermore, these centres are often built in large halls, where unused space can be found on and near walls. In this thesis, a system is analysed that makes use of such free space on walls together with plastic balls to enable digital sports games in this context. This system overall consists of a projector that projects a game environment onto a wall. The plastic balls are then thrown onto the projection surface. The entire process is filmed by a camera that detects the balls, tracks them and calculates the corresponding impact points to enable correct interaction with the game. For the detection and tracking of the balls, standard real-time computer vision techniques of the OpenCV library are applied to implement system. The proposed system is then put into comparison with a laser grid based approach.
