A sports simulation system comprises a projectile tracking apparatus configured to detect a projectile traveling through a projectile tracking region towards a display surface, a controller comprising one or more actuatable buttons, each actuatable button configured to communicate one or more control signals in response to actuation thereof, and at least one processing stage configured to receive data from the projectile tracking apparatus and determine three-dimensional positions, velocity and acceleration of a detected launched projectile traveling through said projectile tracking region, the three-dimensional positions, velocity and acceleration used by said at least one processing stage to calculate a trajectory of said launched projectile into a three-dimensional sports scene, receive one or more control signals from the controller and determine one or more control commands of one or more animated objects based on the one or more control signals, and use said calculated trajectory and said one or more control commands to generate updated image data including a simulation of said launched projectile into said three-dimensional sports scene and manipulate one or more animated objects associated with said three-dimensional sports scene, the updated image data associated with a sports result.

Sports simulation system

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.

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.

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.
