  • Patent number: 10099144
    Abstract: A golf simulation system includes a processor configured to receive image data from a launch area sensing unit to determine position, velocity, acceleration and spin of a golf ball and to calculate a trajectory of the golf ball into a golf scene presented on a display surface. The system includes a processor that generates a profile of a golf ball travel path over a plurality of images, determines the golf ball travel path length per image of the plurality of images, identifies regions corresponding to one or more markings on the golf ball, determines the distance between the regions in each image, calculates the spin rate and tilt of the golf ball using the determined distance, and uses the golf ball travel path length and camera device frame rate to estimate a spin tilt axis of the golf ball using the orientation of the regions in each image and the relative angle between the longitudinal axis of the regions and the longitudinal axis of the golf ball travel path.

  • Patent number: 9649545
    Abstract: A golf simulation system includes imaging devices capturing images of a projectile tracking region in front of a display surface from different vantages to detect a launched projectile traveling through the projectile tracking region towards the display surface. A projectile spin sensing unit captures images of a region at least partially overlapping with the projectile tracking region, and each captured image includes a projectile trail representing a travel path of the projectile. A processing stage receives data from the imaging devices and the projectile spin sensing unit and determines the three-dimensional positions, velocity, acceleration and spin of the projectile, and the three-dimensional positions, velocity, acceleration and spin are used by the processing stage to calculate a trajectory of the launched projectile into a presented golf scene.

  • Patent number: 9381398
    Abstract: A sports simulation system includes a projectile tracker having a display presenting a three-dimensional sports scene. The projectile tracker captures images of a projectile tracking region disposed in front of the display to detect a launched projectile traveling through the tracking region towards the display. A processing stage, in communication with the projectile tracker, is responsive to data received from camera devices to determine three-dimensional positions, velocity, acceleration and spin of a detected projectile traveling through the tracking region, which are used by the processing stage to calculate a trajectory of the launched projectile into the three-dimensional sports scene.
