  • Tee image-capture devices 121 are operable to capture image data proximate to the tee 112. Such image data may include the locations of golf ball 110 and an arc of an approaching golf club 102.
  • tee im- age-capture devices 121 may capture data relating to an arc of swing 211A of the golf club 102 approaching the ball 110; the trajectory of the golf ball 110 after it is struck by golf club 102; an arc of swing 211A of the golf club 102 after launching the ball 110; the posture and body move ments of golfer 101; the tee 112; or other image data that may be useful to track ball movement, predict a ball trajectory; predict a time in the air for the ball; predict a location of impact for the ball 110 and other relevant factors.

  • golfer 101 may wish to hit golf ball 110 farther than a certain predetermined distance, such as the distance between tee 112 and the position in which a golf ball landed that was previously hit by himself, a companion, or other person.
  • Target 131 may be surrounded by one or more arrival image-capture devices 123.

Change of direction is programmed so that a threshold change in direction is determined to be an impact of the ball 110 in flight, or in travel along the game field.
  • a timing index is also associated with each change in direction of a ball.
  • the timing in dex is accurate enough to associate, with a high degree of confidence, that a given ball 110 is a ball launched by a particular player from a particular tee. Therefore, in some embodiments, a timing index may include accuracy to within single digit milliseconds.

  • the server can use the time index to synchronize multiple quanta of image data. In practice, this may allow the server to take video files from multiple image-capture de vices 121-123 and synchronize them to create one nearly consistent, multiple-vantage-point dis play of the golfing game.
  • the time index may serve a second purpose as well: computation of a trajectory of golf ball 110.
  • One or more tee image-capture devices 121 may be primarily focused on tee 112. This may enable the tee image-capture devices 121 (or the server) to determine when golf ball 110 has been stuck.
  • tee image-capture de vices 121 may determine a set of coordinates (e.g., Cartesian, cylindrical, spheri cal) for golf ball 110 at time intervals, and associate those coordinates with an appropriate time index. This may allow the server to use dead reckoning or a similar algorithm to compute one or more ballistic quantities: velocity, acceleration, skew, angular velocity (of the ball or relative to one or more fixed points in a field), or angular acceleration. Using these ballistic quantities, a trajectory 21 IB of the golf ball 110 may be computed.

  • ballistic quantities may be computed regarding the club 102 (e.g., the speed of the club, the angle of the club head when striking the ball, etc.). These quantities may also be communicated to the server. [0026]Based upon the trajectory, one or more projected landing spots for the golf ball 110 may be computed. The landing spot can then dictate some point value to assign to the golf swing. For example, it may be computed that a trajectory of a ball 110 will bring the ball 110 to land ten yards away from a target. Arrival image-capture devices track an actual point of impact and ar rival of the ball 110 to a final destination.
  • the present invention may include multiple protective encasings for cameras or other im age-capture devices placed throughout the game field and a perimeter of the game field.
  • a pro tective casing may include, for example, a polyvinylchloride (PVC) encasement and/or Plexiglas shield.
  • PVC polyvinylchloride
  • Plexiglas shield Although there is no design limitation to a number of encasements and cameras, the number will generally be dependent upon a size on an area of game play and a field of view of each camera. A typical area of game play may include therefore between three and twenty cam eras and encasements per simultaneous golfer.
  • an X,Y coordinate may be recorded indicating a specific point of impact.
  • another X,Y coordinates may be recorded for a final resting place of the ball.
  • the X,Y coordinates may be relative (for example, they may reflect a system in which, for each golfer, the initial tee position is (0,0)) or global (for example, there may be one static set of all X,Y coordinates for all golfers using the system simultaneously).
  • Other coordinate systems may be useful in various situations (e.g., three-dimensional Cartesian coordinates, polar coordi nates, etc.).
  • Points may be assigned based upon predetermined criteria (e.g., a golf ball landing ten yards away from the target may receive more points than a golf ball landing twenty yards away from the target; a final resting position may also be associated with an award of points).
  • predetermined criteria e.g., a golf ball landing ten yards away from the target may receive more points than a golf ball landing twenty yards away from the target; a final resting position may also be associated with an award of points).
  • a point value may be based on distance traveled by the golf ball (e.g., a golf ball that travels 200 yards may receive more points than a golf ball that travels 150 yards; further, the point value may simply be proportional to the number of yards traveled).
  • This trajectory-based point computation method allows specialized golf games without specialized golf balls.
  • one or more tee image-capture devices 121 may be focused on golfer 101. Accordingly, in addition to images or video of the flight of golf ball 110, images or video of the golfer 101 may also be sent to the server. Additionally, if the server (through, for example, target image-capture device 123) records that golf ball 110 hit or landed near target 131, the server may automatically isolate the image or video of golfer 101 associated with one or more time indices associated with the trajectory of golf ball 110. This allows the server to auto matically edit video of the golfer’s reaction to a good shot. Similarly, the server may be capable of collecting video of the golfer’s body mechanics during one or more such good shots, thus al lowing the golfer to improve the golfer’s golf game.
  • some embodiments may include analysis of a ball 110 trajectory and a “good” shot may be determined based upon a distance to a target. Once a shot is determined to meet criteria for being“good” or“bad” golfer’s reaction may be recorded and one or both of a link to the imagery and the imagery itself may be forwarded to the golfer.
  • a vehicle for the golfer to purchase or otherwise take ownership of the imagery may be presented to the golfer. Imagery of a ball 110 landing and going into a hole may also be dis played upon a viewing screen to assist in eliciting a response from the golfer 101 and/or other game participants.
  • the server is in logical connection with a communications network and may transmit the video of the golfer 101 to a desired location, such as a smart device associ ated with golfer 101, a manager of the golfing game, or a third party.
  • the server may also transmit a computed trajectory of golf ball 110 to the golfer 101’ s smart device. This may allow the golfer 101 to build a profile of distances he has struck golf balls with certain clubs (e.g., golf er 101 may average 170 yards with a 4-iron club). This information may be displayed on golfer 101’s smart device.
  • Weather data may also be transmitted to golfer 101’s a controller used in performing the functions described herein, and/or a user’s smart device.
  • Weather data may be referenced as a variable in determining a trajectory of a launched ball.
  • a weather condition that includes high humidity may have considerable effect on a launched ball 110 that has relatively prominent dimples and less effect on a ball 110 that has less prominent dimples.
  • Dimple design, density and material may also be referenced as a variable of ball 110 travel.
  • golfer 101’ may enhance golfer 101’s club profile. For example, while golfer 101 may average 170 yards with a 4-iron on a clear day, golfer 101 may only average 140 yards with a 4-iron on a rainy day. The golfer 101’s profile may account for these weather differences.
  • display 141 may comprise an audio transmission apparatus, such as speakers.
  • the audio transmission apparatus may be operable to receive from the server an indication that the golfer 101 hit golf ball 110 in such a way that it landed at the target, exceeded golfer 101’s average distance with a particular club, or any other noteworthy hit.
  • audio transmission apparatus may generate a certain sound, such as a cheer, to enhance enjoyment of the game.
  • arrival image-capture devices 123 may monitor the progress of ball 110 as it comes to a stop.
  • the trajectory of golf ball 110 may be projected by the server, in some embod iments it can be inferred that the ball missed the target 131 if one or more arrival image-capture devices 123 do not detect golf ball 110 near the time at which golf ball 110 was projected to land near target 131.
  • a time of impact and a point of impact may also be determined based upon an actual path of travel of a ball 110 that includes a sharp deviation in the path and/or velocity of the ball 110. For example a change of ball 110 travel from speed X to speed X-Y (or zero) may indi cate an impact. Similarly, a change of direction greater than 15 degrees (or other delta in trajec tory) may be measured via image sensors and/or impact transducers and interpreted to be an im pact.
  • one or more wind speed sensors may be placed in and around one or more of: the tee, the field, or the target. These sensors may be in logical connection with the server, and data from the sensors may be used to inform the computation of the trajectory of golf ball 110. Examples of other atmospheric data that may be detected by one or more sensors and used to inform the trajectory computation include: wind direction, temperature, humidity, and precipitation detectors.
  • the adaptability of the present invention allows for multiple disparate facilities at different locations to conduct cooperative competitions. Each facility may adopt a configuration for a par ticular competition event and players at the multiple facilities may compete as if they were all present at a single facility.
  • the present invention allows for course features, such as obstacles (e.g., sand traps, water, mounds) to be replicated in multiple facilities for a specified duration of play, which may only be a single round and then changed for a second duration of play since the basis for the award of points is based upon a determined X,Y coordinate (or other coordinate system) of a final ball position, not RFID detection which is much more difficult to move or reconfigure.

Abstract

La présente invention concerne un système et un procédé de jeu de golf à faible coût créés à l'aide d'un ou de plusieurs dispositifs de capture d'image. Les dispositifs de capture d'image peuvent capturer des images ou une vidéo d'un élan de golf et les transmettre à un serveur, qui calcule une trajectoire d'une balle de golf frappée. À l'aide de cette trajectoire, un point d'atterrissage projeté peut être calculé et des points sont attribués en conséquence. Contrairement aux systèmes connus jusqu'à présent, qui nécessitent des balles ou des clubs de golf spécialisés, la présente invention nécessite simplement des caméras à haute définition.
