Computer Vision System For Tracking Ball Movement And Analyzing User Skill
A computer processor of the mobile device may overlay a shape graphic on a fixed area of a screen of the mobile device. A camera of the mobile device may search the fixed area for a ball with a marking. The computer processor may recognize the marking on the ball. The computer processor may calibrate the movement of the ball in the overlayed shape graphic in view of the recognized marking of the ball. The camera may track and may record data pertaining to the movement of the ball. The computer processor may calculate one or more metrics relating to ball controlling abilities from the data. The computer processor may display the one or more metrics on the screen.

- 1. A method, comprising:
overlaying, by a computer processor of the mobile device, a shape graphic on a fixed area of a screen of the mobile device; searching, by a camera of the mobile device, the fixed area for a ball with a marking authorized by the mobile device for enabling calibration and tracking; recognizing, by the computer processor, the authorized marking on the ball; calibrating, by the computer processor, characteristics of the ball in the overlayed shape graphic for tracking of the ball in view of the authorized marking on the ball; tracking and recording, by the camera, data pertaining to the movement of the ball; calculating, by the computer processor, one or more metrics relating to ball controlling abilities from the data; and displaying, by the computer processor, the one or more metrics on the screen, wherein the one or more metrics are calculated and displayed while ball tracking pertaining to the movement of the ball is taking place; displaying, by the processing device, a training video of a character or person executing movements of the ball on the screen of the mobile device; and comparing, by the processing device, the movements of the ball in the training video to the movements of the ball while ball tracking is taking place.
- 23. A mobile device, comprising:
a memory; a computer processor, operatively coupled to the memory; a screen, coupled to the computer processor; and a camera, coupled to the computer processor, the camera to:
search a fixed area of the screen for a ball with a marking authorized by the mobile device for enabling calibration and tracking; and
track and record data pertaining to the movement of the ball;
the computer processor to:
overlay a shape graphic on the fixed area of the screen; recognize the authorized marking on the ball;
calibrate characteristics of the ball in the overlayed shape graphic for tracking of the ball in view of the authorized marking on the ball;
calculate one or more metrics relating to ball controlling abilities from the data;
display the one or more metrics on the screen, wherein the one or more metrics are calculated and displayed while ball tracking pertaining to the movement of the ball is taking place;
display a training video of a character or person executing movements of the ball on the screen of the mobile device; and
compare the movements of the ball in the training video to the movements of the ball while ball tracking is taking place.
