Systems and methods for monitoring user performance in launching an object at a sporting event
Methods and apparatus for monitoring user performance in launching objects at sporting events are described. A described method includes capturing, with a camera on glasses worn by a player participating in a sporting event, a plurality of two-dimensional (2-D) images of an object launched by a player participating in the sporting event. The launched object is identified and tracked with the camera for which an orientation is determined using an accelerometer. Based on the tracking, a position of the launched object at a point along a trajectory relative to a stationary object is determined, and an output indicative of user performance is provided based on the determined position of the launched object.
1. A method, comprising:
capturing, with a camera on glasses worn by a player participating in a sporting event, a plurality of two-dimensional (2-D) images of an object launched by a player participating in the sporting event;
identifying the launched object in the plurality of 2-D images;
tracking the launched object based on the plurality of 2-D images, the tracking comprising determining positions of the launched object in three-dimensional (3-D) space;
determining an orientation of the camera based on at least one accelerometer and at least one of the plurality of 2-D images, wherein the determining the positions of the launched object in 3-D space is based on the determined orientation;
identifying a stationary object in the plurality of 2-D images;
determining a position of the launched object at a point along the trajectory relative to the stationary object based on the tracking;
providing an output based on the determined position of the launched object at the point along the trajectory relative to the stationary object; and
rendering a simulation of the trajectory based on the tracking.
2. The method of claim 1 , wherein the stationary object is a goal to which the launched object is shot in the sporting event.
3. The method of claim 1 , wherein the stationary object includes a marking for a boundary of a court or field on which the sporting event is played.
4. The method of claim 1 , wherein the determining the orientation of the camera is based on the stationary object.
5. The method of claim 1 , wherein launched object is a ball.
6. The method of claim 1 , wherein the determining the orientation of the camera based on the at least one accelerometer is performed for each of the plurality of 2-D images, and wherein the capturing is performed as the player wearing the glasses is moving.
7. The method of claim 6 , wherein the determining the orientation of the camera is based on the stationary object.
8. The method of claim 1 , wherein the determining the orientation of the camera comprises determining a reference plane based on the at least one accelerometer.
9. The method of claim 8 , wherein the determining the positions of the launched object in 3-D space is based on the reference plane.
10. A system, comprising:
a camera positioned on glasses to be worn by a player participating in a sporting event, the camera configured to capture a plurality of two-dimensional (2-D) images of an object launched by a player participating in the sporting event; and
at least one processor programmed with instructions that, when executed by the at least one processor, cause the at least one processor to:
identify the launched object in the plurality of 2-D images;
determine an orientation of the camera based on at least one accelerometer and at least one of the plurality of 2-D images;
track the launched object based on the plurality of 2-D images by determining positions of the launched object in three-dimensional (3-D) space based on the determined orientation;
identify a stationary object in the plurality of 2-D images;
determine a position of the launched object at a point along the trajectory relative to the stationary object;
provide an output based on the determined position of the launched object at the point along the trajectory relative to the stationary object; and
render a simulation of the trajectory based on tracking of the launched object by the at least one processor.
11. The system of claim 10 , wherein the stationary object is a goal to which the launched object is shot in the sporting event.
12. The system of claim 10 , wherein the stationary object includes a marking for a boundary of a court or field on which the sporting event is played.
13. The system of claim 10 , wherein the instructions, when executed by the at least one processor, cause the at least one processor to determine the orientation of the camera based on the stationary object.
14. The system of claim 10 , wherein launched object is a ball.
15. The system of claim 10 , wherein the instructions, when executed by the at least one processor, cause the at least one processor to determine the orientation of the camera based on the at least one accelerometer for each of the plurality of 2-D images, and wherein the plurality of 2-D images is captured as the player wearing the glasses is moving.
16. The system of claim 15 , wherein the instructions, when executed by the at least one processor, cause the at least one processor to determine the orientation of the camera based on the stationary object.
17. The system of claim 10 , wherein the instructions, when executed by the at least one processor, cause the at least one processor to determine a reference plane based on the at least one accelerometer, and wherein the determined orientation is based on reference plane.
18. The system of claim 17 , wherein the instructions, when executed by the at least one processor, cause the at least one processor to determine the positions of the launched object in 3-D space based on the reference plane.
