A cricket sensor may include one or more first image-capturing sensors configured to capture image data of a pitching motion of a bowler and image data of an initial motion of a cricket ball at a bowling end of a cricket field. The cricket sensor may include one or more second image-capturing sensors configured to capture image data of a trajectory and a flight path of the cricket ball towards a batting end of the cricket field. The cricket sensor may also include one or more first radar sensors configured to capture radar data describing one or more initial launch parameters of the cricket ball related to the trajectory and the flight path of the cricket ball towards the batting end of the cricket field.

The present invention relates to a virtual golf device and a hitting mat that may be used in the virtual golf device. The virtual golf device comprises a hitting mat on which a real golf ball for a user to hit is placed and which has a fairway area and a non-fairway area, a display part displaying a virtual golf course, a calculating part calculating a movement of a virtual golf ball corresponding to the real golf ball in the virtual golf course when the user hits the real golf ball, and a state change means changing the hitting mat to a first state or a second state, wherein if a direction of hitting the real golf ball is called a front, the first and second states are symmetrical to each other when viewed from the front.

A golf ball sensing apparatus for use with a portable electronic device including a data acquisition device and a processing unit, and in association with a golf club and a cup. The apparatus includes a golf ball, at least one sensor carried by the ball and a non-transitory computer-readable medium. The sensor senses at least one attribute of the ball. The medium directs a processing unit to identify the initiation of a first stroke of the ball towards the cup, obtain a first final location after the first stroke, obtain the at least one attribute of the first stroke, store a set of associated data regarding the first stroke, obtain a second initial location of the ball prior to a subsequent second stroke, and output portions of the stored set of data in response to the second initial location being within a predetermined zone of the first initial location.

A system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

An apparatus, methods and systems are provided for creating a shot information database comprising ball flight data combined with a user's intended golf shot type, the user's golf club selection, the user's setup position and dynamic swing adjustment made to produce the golfer's intended golf shot with the selected golf club to produce said golf shot. This invention presents to the user such information as a score, wherein said score reflects the accuracy of the user's golf shot. In addition, the ball flight data includes a trajectory angle, an elevation angle, a quadrant in a target plane comprising an x-y coordinate system coplanar with said target plane and a characterization of a type of golf shot produced by said golfer, such as a draw. Another embodiment of this invention performs a statistical analysis on said shot information to create basic and advance shot reports to assist a golfer or a third party to learn a golfer's strengths and weaknesses with respect to the user's ability to hit certain golf shots with certain golf clubs; in addition, the golfer is able to learn with setup keys and swing keys are more successful in hitting certain golf shots with certain golf clubs. In this manner a golfer or user is able to learn what it takes to improve his/her golf swing while better understanding their particular capabilities and tendencies. Another embodiment of this invention allows a golfer to practice indoors in a manner that simulates outdoor practice at a driving range, For golfer's who are visually impaired, this invention provides accurate feedback to a golfer who is visually impaired to the extent that they cannot see the flight of the struck golf ball. Said golfer benefits little at a driving range where they are unable to see the results of their golf swings This apparatus characterizes each golf shot using a particular practice ball which interoperates with the apparatus in such a way to enable said apparatus to acquire said ball flight data. Another embodiment of this invention allows a golfer to enter or speak remarks on the results of the previous shots or, more simply called post shot remarks. All shot information is stored in permanent storage for later historical performance analysis.

A method for determining golf shot characteristics includes detecting, in imaging data captured by an imager, a signature of a golf shot launched from a first launch area, a field of view of the imager including one of the first launch area and an area adjacent to the first launch area, and determining, from the imaging data, first golf shot characteristics, the first shot characteristics including a first launch location and a first launch time in combination with determining whether the first launch location and the first launch time correspond to a second launch location and a second launch time for second golf shot characteristics determined from sensor data captured by a further sensor arrangement and when no correspondence is found between the first and second launch locations and the first and second launch times, transmitting the first shot characteristics to a display at the first launch location.

A sports simulator calculates spin of a sports object using image analysis. A velocity vector is also calculated. These are combined to produce a predicted future trajectory of the sports object. In one embodiment, the sports object is a golf ball and the sports simulator simulates golf.

In a case in which the size of a moving body changes by a position of the moving body, in order to accurately track the moving body without an effort of the user regardless of a change in the size, the present disclosure estimates a size of the moving body in each of the images of the frames, updates template data based on the estimated size of the moving body, and compares a candidate region that is a candidate of a region where the moving body is present in each of the images of the frames with the template data, and determines whether or not the moving body is positioned in the candidate region based on the comparison result.

A system for coordinating radar data and image data to track a flight of a projectile includes a radar, an imager, and a controller. The imager provides an image of an area into which a projectile is to be launched. The controller receives the image and an identification of a target within the image and identifies a target line connecting the target and a launch position of the projectile. The controller also receives data from the radar relative to at least a portion of a trajectory of the projectile, generates image based trajectory data by correlating the radar data and the image, and alters the image to include the image based trajectory data within the image and the target line within the image.
