Methods and systems for ball game analytics with a mobile device

A system for detecting a ball shot attempt, comprising:

• at least one processor;
• and
• a non-transitory physical medium for storing program code and accessible by the processor, the program code when executed by the processor causes the processor to:
• receive an input video captured using a camera on a mobile computing device, wherein the input video comprises a ball shot attempt at a goal;
• receive a declared ball shot attempt, the declared ball shot attempt detected by analyzing a ball trajectory in the input video using a first computer vision algorithm;
• adjust a goal element movement threshold to generate an adjusted goal element movement threshold based on a scene detection result in the input video from a second computer vision algorithm;
• detect a goal element movement associated with an integral element of the goal using the second computer vision algorithm based on the adjusted goal element movement threshold;
• and
• determine the ball shot attempt result based on the goal element movement from the second computer vision algorithm and the ball trajectory from the first computer vision algorithm.

A non-transitory computer-readable storage medium for a ball shot attempt, the storage medium comprising program code stored thereon, that when executed by a processor causes the processor to:

• receive an input video captured using a camera on a mobile computing device, wherein the input video comprises a ball shot attempt at a goal;
• receive a declared ball shot attempt, the declared ball shot attempt detected by analyzing a ball trajectory in the input video using a first computer vision algorithm;
• adjust a goal element movement threshold to generate an adjusted goal element movement threshold based on a scene detection result in the input video from a second computer vision algorithm;
• detect a goal element movement associated with an integral element of the goal using the second computer algorithm based on the adjusted goal element movement threshold;
• and
• determine the ball shot attempt result based on the goal element movement from the second computer vision algorithm and the ball trajectory from the first computer vision algorithm.
