A basketball system comprising a court system having shot locations defined by shot location lines on the play surface and the shot areas defined by shot area lines on the play surface, and a goal system comprising a respective backboard suspended above the play surface at each opposing farthest end of the play surface, an instrumentation system comprises sensors to detect activities within the boundary line of the court system, and a respective penalty box for each team in which players, coaches, and referees can serve a penalty assessed for an infraction.

A system and method for generating a play prediction for a team is disclosed herein. A computing system retrieves trajectory data for a plurality of plays from a data store. The computing system generates a predictive model using a variational autoencoder and a neural network by generating one or more input data sets, learning, by the variational autoencoder, to generate a plurality of variants for each play of the plurality of plays, and learning, by the neural network, a team style corresponding to each play of the plurality of plays. The computing system receives trajectory data corresponding to a target play. The predictive model generates a likelihood of a target team executing the target play by determining a number of target variants that correspond to a target team identity of the target team.

A trajectory and a flight distance of a target moving body such as a ball hit by a golf club in an athletic competition such as a golf game may be calculated from the images having been taken. The calculation may be conducted from the pictures having been taken with a monocular camera of low resolution such as a smartphone. An initial velocity and a hitting angle of a target moving body such as a ball having been hit high by the golf club may be calculated.

Methods, systems, and apparatus, including medium-encoded computer program products, for 3D flight tracking of objects includes, in at least one aspect, a method including obtaining two dimensional image data of a golf ball in flight, the two dimensional image data originating from a camera; obtaining radar data of the golf ball in flight, the radar data originating from a Doppler radar device associated with the camera; interpolating the radar data to generate interpolated radar data of the golf ball in flight; and blending radial distance information derived from the interpolated radar data of the golf ball in flight with angular distance information derived from the two dimensional image data of the golf ball in flight to form three dimensional location information of the golf ball in three dimensional space.

The present invention includes systems and methods for automated detection and visualization of offside positions. In soccer, offside is determined by the position of a player relative to the position of players on the opposing team and/or the soccer ball. The present invention provides systems and methods for tracking the location of players on a soccer field and for determining whether a player is in an offside position. The present invention further includes an imaging system for tracking the location of a boundary object that determines where offside positions begin. The system is then operable to enhance image and video data using the data collected during detection of offside positions.
