Abstract

In a method for assisting a golf player in tracking golf shots comprises, a video camera is operated at one point along a golf course fairway to generate a video signal encoding an image of a plurality of substantially stationary objects and of a target golf ball moving relative to the stationary objects. A computer is operated to process the video signal to detect the target golf ball, to automatically determine a path of motion of the target golf ball, and to modify at least a portion of the video signal to superimpose on a display of the stationary objects a curvilinear indication of the determined path of motion of the target golf ball. The camera is moved along the fairway toward the resting golf ball. The image displayed in modified to incorporate the changing view of the fairway, as well as a changed portion of the golf ball'"'"'s path.

Claims

1. A method for assisting a golf player in tracking golf shots, comprising:

operating a video camera at an initial location along a golf course fairway to generate a first video signal encoding a first image of a plurality of substantially stationary objects along said fairway and of a target golf ball moving relative to said stationary objects;

providing a computer and a display, said computer being operatively connected to said camera for receiving said video signal therefrom, said computer being connected to said display;

operating said computer to process said video signal to detect said target golf ball;

further operating said computer to automatically determine a path of motion of said target golf ball and an end point of said path of motion;

additionally operating said computer to modify at least a portion of said video signal to superimpose on a view of said stationary objects a curvilinear indication of the determined path of motion of said target golf ball;

also operating said computer to display on said display said view with said indication of said determined path of motion;

after the display of said view with said indication of said determined path of motion, moving said video camera along said fairway from said initial location toward said end point;

between said initial location and said end point, operating said video camera to generate a second video signal encoding a second image of only some of said substantially stationary objects along said fairway;

supplementally operating said computer to modify at least a portion of said second video signal from said camera to superimpose on said second image a downstream or end segment of said curvilinear indication of said determined path of motion, thereby enabling a user to visualize said path of motion on said display as the user approaches the target golf ball at its location along said fairway.

2. The method defined in claim 1, further comprising operating said computer to process said first video signal to automatically estimate a distance of travel of said target golf ball and to generate a report as to the estimated distance of travel of said target golf ball.

3. The method defined in claim 2, further comprising operating said computer to classify said determined path of motion in one of a plurality of different classes of golf ball strokes or paths, to generate a statistical quantity incorporating the classification of said determined path of motion, and to store said statistical quantity.

4. The method defined in claim 2, further comprising operating said computer to generate a statistical quantity incorporating said estimated distance of travel, and to store said statistical quantity for subsequent communication to a user.

5. The method defined in claim 1, further comprising operating said computer to provide visually differentiable path indicators for different golf balls.

6. The method defined in claim 5, further comprising operating said computer to generate said visually differentiable path indicators in different colors on said display.

7. The method defined in claim 1, further comprising storing at least a portion of said first video signal for later replay to a user.

8. The method defined in claim 1, further comprising operating said computer to classify said determined path of motion in one of a plurality of different classes of golf ball strokes or paths, to generate a statistical quantity incorporating the classification of said determined path of motion, and to store said statistical quantity.

9. The method defined in claim 1, further comprising operating said computer to generate at least one statistical quantity pertaining to a player'"'"'s golf stroke and to store said statistical quantity for subsequent communication to said player.
