Methods and systems for generating sports analytics with a mobile device

A single mobile computing device for generating ball shot analytics, comprising:

• a processor on the single mobile computing device;
• and
• a non-transitory computer readable storage medium for storing program code and accessible by the processor, the program code when executed by the processor causes the processor to:
• receive, on the processor on the single mobile computing device, an input video of a ball game, and a location of a shooter in a shooter identification frame of the input video;
• detect, on the processor on the single mobile computing device, one or more balls and one or more player postures from the input video;
• generate, on the processor on the single mobile computing device, one or more ball flows and one or more posture flows by grouping the one or more balls and the one or more player postures along a time line;
• identify, on the processor on the single mobile computing device, a generated player posture flow as a shooter posture flow, based on an input location of the shooter;
• identify, on the processor on the single mobile computing device, a generated ball flow as a related ball flow to the shooter posture flow;
• determine, on the processor on the single mobile computing device, a ball-from-shooter time by backtracking the related ball flow from a shot attempt;
• determine, on the processor on the single mobile computing device, a shot event occurring before the ball-from-shooter time;
• and
• generate, on the processor on the single mobile computing device, one or more shot analytics based on the shot event, the shooter posture flow, and the related ball flow.

A non-transitory computer readable storage medium for generating ball shot analytics, the non-transitory computer readable storage medium comprising program code stored thereon, the program code when executed by a processor on a single mobile computing device causes the processor to:

• receive, on the processor on the single mobile computing device, an input video of a ball game, and a location of a shooter in a shooter identification frame of the input video;
• detect, on the processor on the single mobile computing device, one or more balls and one or more player postures from the input video;
• generate, on the processor on the single mobile computing device, one or more ball flows and one or more posture flows by grouping the one or more balls and the one or more player postures along a time line;
• identify, on the processor on the single mobile computing device, a generated player posture flow as a shooter posture flow, based on an input location of the shooter;
• identify, on the processor on the single mobile computing device, a generated ball flow as a related ball flow to the shooter posture flow;
• determine, on the processor on the single mobile computing device, a ball-from-shooter time by backtracking the related ball flow from a shot attempt;
• determine, on the processor on the single mobile computing device, a shot event occurring before the ball-from-shooter time;
• and
• generate, on the processor on the single mobile computing device, one or more shot analytics based on the shot event, the shooter posture flow, and the related ball flow.
