Abstract

A gaming machine includes at least one image sensor for capturing an image including a player area associated with the gaming machine and logic circuitry in communication with the image sensor. The logic circuitry establishes a facial image mask defining an area of interest within the player area, receives the captured image from the image sensor, applies the facial image mask to the captured image to extract player image data from the captured image data, detects any faces within the player image data, compares, in response to detecting a face of a player within the player image data, the detected face with a player database to identify a player account associated with the player, and links, in response to identifying a matching player account based on the comparison, the matching player account to activities of the player at the gaming machine.

First claim

The invention claimed is:

1. A gaming machine comprising:
at least one image sensor configured to capture an image including a player area associated with the gaming machine; and
logic circuitry in communication with the at least one image sensor, the logic circuitry configured to:
prior to player detection, establish a facial image mask defining an area of interest within the player area, the facial image mask based at least partially on a physical orientation and a predefined mounting location associated with the gaming machine of each image sensor of the at least one image sensor relative to the player area, wherein the facial image mask is stored for subsequent player detection;
in response to establishing and storing the facial image mask, receive the captured image from the at least one image sensor;
apply the facial image mask to the captured image to extract player image data from the captured image data, the player image data representing at least the area of interest, wherein the facial image mask is initially applied to extract a predefined set of pixels from the captured image, the predefined set of pixels less than a plurality of pixels defining the captured image;
detect any faces within the player image data;
in response to detecting a face of a player within the player image data, compare the detected face with a player database storing a plurality of player account identifiers linked to respective facial features to identify a player account associated with the player; and
in response to identifying a matching player account based on the comparison, link the matching player account to activities of the player at the gaming machine.

2. The gaming machine of claim 1 , wherein the logic circuitry is configured to divide the captured image into a plurality of image segments, the facial image mask comprising a subset of the plurality of image segments.

3. The gaming machine of claim 1 , wherein the logic circuitry is configured to establish the facial image mask by causing a display device of the gaming machine to present a preview of the facial image mask during a calibration process, and wherein the facial image mask is updated in response to user input via the calibration process.

4. The gaming machine of claim 1 , wherein the gaming machine is associated with a gaming table, and wherein the player area includes at least one player position at the gaming table.

5. The gaming machine of claim 1 , wherein a first image sensor of the at least one image sensor is physically separate from a housing of the gaming machine and in communication with the logic circuitry.

6. The gaming machine of claim 1 further comprising a wide-angle camera including the at least one image sensor, wherein the logic circuitry is configured to apply a de-warping transformation to the player image data in response to extracting the player image data.

7. The gaming machine of claim 1 , wherein the physical orientation and the predefined mounting location of each image sensor of the at least one image sensor is selected from a plurality of physical orientations and predefined mounting locations associated with a gaming machine type of the gaming machine.

8. A method for player tracking using a gaming system including a gaming machine and logic circuitry, the gaming machine including at least one image sensor, wherein the method comprises:
capturing, by the at least one image sensor, an image of a player area associated with the gaming machine;
prior to player detection, establishing, by the logic circuitry, a facial image mask defining an area of interest within the player area, the facial image mask based at least partially on a physical orientation and a predefined mounting location associated with the gaming machine of each image sensor of the at least one image sensor relative to the player area, wherein the facial image mask is stored for subsequent player detection;
in response to establishing and storing the facial image mask, receiving, by the logic circuitry, the captured image from the at least one image sensor;
applying, by the logic circuitry, the facial image mask to the captured image to extract player image data from the captured image data, the player image data representing at least the area of interest, wherein the facial image mask is initially applied to extract a predefined set of pixels from the captured image, the predefined set of pixels less than a plurality of pixels defining the captured image;
detecting, by the logic circuitry, any faces within the player image data;
in response to detecting a face of a player within the player image data, comparing, by the logic circuitry, the detected face with a player database storing a plurality of player account identifiers linked to respective facial features to identify a player account associated with the player; and
in response to identifying a matching player account based on the comparison, linking, by the logic circuitry, the matching player account to activities of the player at the gaming machine.

9. The method of claim 8 , wherein the logic circuitry is configured to divide the captured image into a plurality of image segments, the facial image mask comprising a subset of the plurality of image segments.

10. The method of claim 8 , wherein establishing the facial image mask comprises causing, by the logic circuitry, a display device of the gaming machine to present a preview of the facial image mask during a calibration process, and wherein the facial image mask is updated in response to user input via the calibration process.

11. The method of claim 8 , wherein the gaming machine is associated with a gaming table, and wherein the player area includes at least one player position at the gaming table.

12. The method of claim 8 , wherein a first image sensor of the at least one image sensor is physically separate from a housing of the gaming machine and in communication with the logic circuitry.

13. The method of claim 8 , wherein the physical orientation and the predefined mounting location of each image sensor of the at least one image sensor is selected from a plurality of physical orientations and predefined mounting locations associated with a gaming machine type of the gaming machine.

14. The method of claim 8 , wherein receiving the captured image is in response to detecting player presence at the gaming machine using a proximity sensor or detecting player input at the gaming machine.

15. A gaming system comprising:
a gaming machine comprising at least one image sensor configured to capture an image of a player area associated with the gaming machine; and
logic circuitry in communication with the at least one image sensor, the logic circuitry configured to:
prior to player detection, establish a facial image mask defining an area of interest within the player area, the facial image mask based at least partially on a physical orientation and a predefined mounting location associated with the gaming machine of each image sensor of the at least one image sensor relative to the player area, wherein the facial image mask is stored for subsequent player detection;
in response to establishing and storing the facial image mask, receive the captured image from the at least one image sensor;
apply the facial image mask to the captured image to extract player image data from the captured image data, the player image data representing at least the area of interest, wherein the facial image mask is initially applied to extract a predefined set of pixels from the captured image, the predefined set of pixels less than a plurality of pixels defining the cap
