Systems and methods for monitoring user performance in launching an object at a sporting event

A method for use at a sporting event, comprising

• receiving a plurality of two-dimensional (2D) images captured by at least one image sensor positioned on glasses worn by a user at the sporting event;
• identifying, within the plurality of 2D images with at least one processor, an object launched along a trajectory by a player participating in the sporting event;
• identifying, with the at least one processor, a stationary object at the sporting event within the plurality of 2D images based on a shape of the stationary object within the plurality of 2D images;
• determining, with the at least one processor, an orientation of the at least one image sensor in three-dimensional (3D) space based on a shape of the stationary object within the plurality of 2D images;
• determining, with the at least one processor, a plurality of locations of the launched object in 3D space along the trajectory based on the plurality of 2D images and the determined orientation of the at least one image sensor;
• determining, with the at least one processor, the trajectory of the launched object in 3D space based on the plurality of locations of the launched object in 3D space;
• determining, with the at least one processor, a parameter indicative of a performance of the player for the sporting event based on the determined trajectory;
• and
• providing, with the at least one processor based on the parameter, feedback indicative of the performance of the player for the sporting event.
