Abstract:
Methods and systems for ball shot attempt detection and game analytics generation are disclosed. The methods and systems perform steps to receive an input video of a ball gameplay, wherein the input video was captured using a stationary camera, and wherein frames of the input video comprises a goal; identify a Region of Interest (ROI) surrounding the goal by performing a first computer vision algorithm on the input video; detect a ball within the ROI during a shot attempt and determining a trajectory of the ball by performing a second computer vision algorithm on the input video; and identify a player relevant to the shot attempt based on the trajectory of the ball. In some embodiments, the computer vision algorithms comprise a convolution neural network (CNN). The present invention uses computer vision techniques to enable a resource-limited mobile device such as a smartphone to efficiently execute the new process.

Claim (Index 1):
A method for detecting a ball shot attempt captured by a single stationary camera, comprising:\n receiving an input video captured using the single stationary camera, wherein frames of the input video comprise a goal; detecting the goal, using a Convolutional Neural Network (CNN) module, by detecting more than one key feature points of the goal from the input video, wherein the CNN module has been trained using one or more prior input videos; identifying a ball tracking Region of Interest (ROI) surrounding the goal; detecting a ball within the ball tracking ROI over the frames of the input video; determining a trajectory of the ball over the frames of the input video; and detecting a ball shot attempt by analyzing the trajectory of the ball relative to the goal.
