Abstract
The embodied invention is a method and equipment suitable for a shooting game with dynamic shot recognition and automatic scoring among multiple players firing at the same target. Each player's shot is scored based on a difference in the target's image from a prior image as viewed by a camera. The scoring target is aligned with the camera, and the output of the score change is displayed to the multiple shooters.
Claims22
A shooting game with a dynamic scoring system comprising:
- A) a target mounted in a support frame,
- B) a digital camera mounted on said support frame with a sensor resolution of at least 2 million pixels,
- C) wherein said digital camera is located above the target with a view of the target,
- D) wherein a distance of said digital camera to the target is not greater than the maximum of:
- a) the width of said target, or
- b) the height of said target,
- E) wherein a constant light illuminates the target,
- F) a sequential hole made in the target during the shooting game,
- G) wherein said digital camera captures video images of the sequential hole made in the target,
- H) wherein the video images incorporate said target and are displayed on at least one game display,
- I) wherein the video images are processed by image processing equipment to determine a location of a new hole in the target by comparing a current image to a prior image substantially one second earlier, wherein said current image is free of shot vibration,
- J) wherein said location of the new hole is recognized when at least 0.02% of pixels change from said current image to said prior image,
- K) correcting the location of the new hole for vertical and horizontal distortion,
- L) scoring the new hole in the target relative to scoring markings on the target,
- M) displaying a marker on the game display that identifies the most recent target hole location, and
- N) updating the shooting game score.
(canceled)
The shooting game according to claim 3 wherein the video images are processed by the image processing equipment to determine the location of the new hole in the target by the steps comprising:
- A) converting the video images to grayscale images,
- B) filtering the grayscale images by averaging the RGB values of sequential image pixels with immediately surrounding sequential image pixels,
- C) comparing the filtered grayscale images to identify any image pixel change from a prior baseline image,
- D) wherein said prior baseline image is substantially 1 second in the past,
- E) examining a surrounding one square inch area of any changed pixel for other changed pixels and performing a changed pixel count in the one square inch area,
- F) identifying the new hole when the number of changed pixel counts in the one square inch area exceeds a threshold value of 25%, and
- G) identifying an averaged pixel location of the new hole based on an average changed pixel location in the one square inch area.
