Method and systems using prediction of outcome for launched objects

Each golfer (1-3) on a golf range (4) has an individual display (12-14) showing at least a predicted outcome of each of his / her shots, and a launch-analyser (6-8) to measure velocity vectors of the ball and / or club at strike for central-computation (9) of the prediction. Vibration and piezo-cable sensors (54,55;68,69) at instrumented targets (5;41-45,47) distributed throughout the range (4), detect the presence of balls arriving in their respective locations for matching with launched balls using the computed predictions and probability; active or passive radio-frequency identification and location of balls may also be used. Where a match is found, error between predicted and actual outcome is applied to adaptive correction of the prediction-computing process, and the actual outcome is displayed to the golfer instead of the prediction. Ball and / or club velocity vectors, and ball spin, at launch are measured from light changes occurring in detection planes (96,97;105;114-117;134;144-146) defined by slit apertures (94,95;104), and resulting from retro-reflection from ball (91;110;131) and / or club (130).

Sports simulation system

A sports simulation system includes a projectile tracking apparatus having a display surface on which a visually apparent three-dimensional sports scene is presented. The projectile tracking apparatus captures images of a projectile tracking region disposed in front of the display surface to detect a launched projectile traveling through the projectile tracking region towards the display surface. At least one processing stage communicates with the projectile tracking apparatus and is responsive to the image data to determine the three-dimensional positions, velocity and deceleration/acceleration of a detected projectile traveling through the projectile tracking region. The determined three-dimensional positions, velocity and deceleration/acceleration are used by the at least one processing stage to calculate a trajectory of the launched projectile into the visually apparent three-dimensional sports scene. Updated image data is generated by the at least one processing stage that includes a simulation of the launched projectile into the visually apparent three-dimensional sports scene following the calculated trajectory. A display device coupled to the at least one processing stage receives the image data from the at least one processing stage and presents the visually apparent three-dimensional sports scene, including the simulation, on the display surface.

Method and an apparatus for capturing three-dimensional data of an area of space

In a method for capturing three-dimensional data of an area of space, a plurality of measuring beams (Ls) are sent out to a plurality of measuring points. A detector (50) receives a plurality of reflected beams (Lr) which are reflected by the measuring points (34a). A plurality of distances to the measuring points (34a, 34b) are determined as a function of the reflected beams (Lr). According to one aspect of the invention, at least one object (30) which comprises a hidden channel (66) having a visible entry opening (72) is located in the area of space. A rod-shaped element (32) is inserted into the channel (66) in such a manner that a free end (70) protrudes from the entry opening (72). A first distance to a first measuring point (34a) and a second distance to a second measuring point (34b) are determined. An orientation (74) of the hidden channel (66) is determined as a function of the first and the second distances.
