DETAILED DESCRIPTION
An embodiment according to the present invention will be
specifically described below with reference to the drawings.
First, a game that is played in an amusement place having
a gaming table 10 will be described. Although the present
embodiment shows an example in which the gaming table 10 is a
baccarat table and a baccarat game is played, the present
invention is also able to other amusement places or other
games.
is a diagram schematically showing an amusement
place. As shown in the drawing, in the amusement place there
are disposed a ntially semicircular gaming table 10 and
chairs 11 which are arranged along the arc side of the gaming
table 10 so as to face a dealer D. The number of the chairs
11 is any. In the example of Fig. 1, six chairs 11 are provided
(they are called chairs 11a to 11f in order from the right side
on the paper of the gaming table 10, and are collectively called
chairs 11). In addition, g areas 12 are provided on the
gaming table 10 for the respective chairs 11 (they are called
betting areas 12a to 12f in order from the right side on the
paper of the gaming table 10, and are collectively called
betting areas 12). Namely, the six betting areas 12a to 12f
are arranged in an arc-like .
Then, customers (players) C sit in the respective chairs
11a to 11f. Each customer (player) C bets on a Player win, a
Banker win, or a Tie as the winning or losing outcome of the
baccarat game (this is hereinafter referred to as “bet”) by
stacking chips W in a betting area 12 provided in front of a
chair 11 in which the customer (player) C sits.
There may be only one type of chips W to bet or there may
be a plurality of types of chips W to bet. In addition, the
number of chips W to bet may be arbitrarily decided by the
ers (players) C. The present embodiment is to ize
the number (furthermore, the type) of stacked chips W.
The dealer D calls “No more bets” at the right time to
end betting by the ers (players) C and, for example, moves
r hand in a crosswise direction. Then, the dealer D draws
cards one by one from a card shooter apparatus S onto the gaming
table 10. As shown in the first card is a Player’s hand,
the second card is a Banker’s hand, the third card is a Player’s
hand, and the fourth card is a Banker’s hand (the drawing of
the first to fourth cards is hereinafter referred to as
“dealing”).
Note that since all cards are drawn face down from the
card shooter apparatus S, neither the dealer D nor customers
(players) C can grasp ranks (numbers) or suits s, diamonds,
spades, or clubs).
After the fourth card is drawn, a customer (player) C who
has bet on the Player (if there are a plurality of customers
C who have bet on the Player, a customer C with the highest bet,
and if there is no customer C who has bet on the Player, the
dealer D) turns over the face-down first and third cards face
up. Likewise, a customer (player) C who has bet on the Banker
(if there are a plurality of customers C who have bet on the
Banker, a customer C with the highest bet, and if there is no
customer C who has bet on the Banker, the dealer D) turns over
the second and fourth cards face up (in general, the turning
over of a face-down card face up is called “squeezing”).
Then, based on the ranks (numbers) of the first to fourth
cards and the detailed rules of the baccarat game, the dealer
D draws the fifth card and r the sixth card, and each of
these cards s a Player’s or Banker’s hand. In the same
manner as above, a customer (player) C who has bet on the Player
squeezes a card that is the Player’s hand, and a customer
(player) C who has bet on the Banker squeezes a card that is
the Banker’s hand.
A period of time before winning and losing outcomes are
found out by squeezing the fifth and sixth cards after drawing
the first to fourth cards is a thrilling time for the customers
(players) C.
Furthermore, depending on the ranks (numbers) of cards,
winning and losing may be decided by the first to fourth cards,
or winning and losing may be finally d by the fifth card
or further by the sixth card. Based on the ranks (numbers) of
the squeezed cards, the dealer D grasps that winning and losing
are decided and grasps winning and losing outcomes, and ms
a task such as pressing a winning and losing outcome display
button on the card shooter tus S to display the winning
and losing outcomes on a monitor to show the customers (players)
C the winning and losing outcomes.
In addition, at the same time, a winning and losing
determiner ed in the card shooter apparatus S ines
the winning and losing outcomes of the game. If, despite the
fact that winning and losing have been d, the dealer D
further attempts to draw a card without displaying the winning
and losing outcomes, an error occurs. The card shooter
apparatus S detects the error and outputs an error signal.
Finally, during a period during which the winning and losing
es are displayed, the dealer D calculates bets made by
the ers (players) C, and makes payouts to winning
customers (players) C and collects bets from losing customers
(players) C. After the completion of the calculation, the
display of the winning and losing outcomes is terminated, and
betting for the next game starts.
Note that the flow of the above-described baccarat game
is widely done in general casinos, and the card shooter
apparatus S is an existing card shooter apparatus that is
configured to read a card to be drawn while being structured
such that a card is drawn out by a hand of the dealer D, and
that further includes an outcome display button and an outcome
display module and has a function of making a winning and losing
determination and displaying winning and losing es. As
bed above, the card shooter apparatus S, a monitor, etc.,
are disposed for each of a plurality of gaming tables 10 ed
on a general casino floor, and cards to be used are supplied
in units of packages or sets or further in units of cartons on
each gaming table 10 or in a cabinet 210 below the gaming table
and utilized.
The present embodiment relates to a chip recognition
system that recognizes chips W that are stacked in the betting
areas 12 by the customers rs) C, and more specifically
to a chip recognition system that recognizes the number and/or
type of chips W.
The chip recognition system includes a single or a
plurality of (two in the example of cameras 1a and 1b.
The camera 1a is disposed on the right side on the paper of the
gaming table 10 and shoots the betting areas 12. On the other
hand, the camera 1b is disposed on the left side on the paper
of the gaming table 10 and shoots the betting areas 12. Note
that the disposition positions of the s 1a and 1b are
merely exemplification, and the cameras 1a and 1b may be
disposed in any on in which the cameras 1a and 1b can shoot
the betting areas 12.
The camera 1a may shoot only a part of the betting areas
12a to 12f, but it is desirable that the camera 1a shoot all
of the betting areas 12a to 12f. When the camera 1a shoots a
plurality of betting areas 12, it is expected that a sharp image
can be obtained for betting areas 12 close to the camera 1a,
but it is also considered that an unsharp image is obtained for
betting areas 12 far from the camera 1a. In addition, it is
expected that a sharp image can be obtained for g areas
12 that are in focus of the camera 1a, but it is also considered
that an unsharp image is obtained for g areas 12 that are
out of focus of the camera 1a. The same things can also be said
for the camera 1b.
Chips W are ized using images obtained by shooting
with the cameras 1a and 1b. Use of a sharp image ses the
accuracy of recognition of the chips W and use of an unsharp
image reduces the accuracy of recognition of the chips W.
is a block diagram g a schematic
configuration of a chip recognition system. The chip
recognition system is to recognize chips W on a gaming table
in an amusement place having the gaming table 10, and includes
cameras 1a and 1b, a game recording apparatus 2, an image
analysis apparatus 3, a plurality of chip determination
apparatuses 4, and an artificial intelligence apparatus for
deciding a correct result 5.
As described above, the cameras 1a and 1b shoot chips W
stacked in the betting areas 12 on the gaming table 10. Images
obtained by the shooting are transmitted to the game ing
apparatus 2 by wireless communication or wired communication.
The game recording apparatus 2 records, as images, the
state of chips W stacked in a game which is played on the gaming
table 10, using the cameras 1a and 1b. Namely, the game
recording tus 2 records the images shot with the cameras
1a and 1b.
The image analysis apparatus 3 performs an image analysis
on the recorded images of the state of chips W. For example,
the image analysis apparatus 3 performs filtering by the size
(the number of pixels), shape (pattern matching), etc., of an
assumed target (chip W) to make a distinction between the chips
W and a background. It is desirable that the image analysis
apparatus 3 be structured such that even if some or a single
whole chip W of a plurality of chips W stacked in the betting
areas 12 are/is hidden due to the blind spots of the cameras
1a and 1b, the image analysis apparatus 3 can obtain information
about the type, number, and position of the chips W.
Specifically, this becomes possible by cial intelligence
by teaching the artificial intelligence an image and the number
of chips in the image as teacher data.
The ity of chip determination apparatuses 4 include,
for example, two cial intelligence apparatuses for
determining the number of chips 4a and 4b and a physical
measurement determination apparatus 4c. Note that the
plurality of chip ination apparatuses 4 may include only
two artificial intelligence apparatuses for determining the
number of chips 4a and 4b, or may include only one artificial
intelligence apparatus for determining the number of chips 4a
and the physical ement determination apparatus 4c, or may
include three or more artificial igence apparatuses for
determining the number of chips, or may include an apparatus
that determines the number of chips by a different technique.
In order that the artificial intelligence apparatuses for
determining the number of chips 4a and 4b can determine the
number of chips W using an image analysis result ed by
the image analysis apparatus 3, the artificial intelligence
apparatuses for determining the number of chips 4a and 4b are
subjected to pre-learning.
The artificial intelligence apparatus for determining
the number of chips 4a determines, using artificial
intelligence, the number of stacked chips W, using a result that
is shot with the camera 1a and recorded as an image and further
subjected to an image analysis. On the other hand, the
artificial intelligence apparatus for ining the number
of chips 4b determines, using artificial intelligence, the
number of stacked chips W, using a result that is shot with the
camera 1b and recorded as an image (i.e., an image different
from the image shot with the camera 1a) and further subjected
to an image analysis.
The physical ement determination apparatus 4c
determines the number of chips W by a physical measurement
method without using artificial intelligence. For a specific
example of the physical measurement method, the number of chips
W may be determined based on the height of the stacked chips
W which is obtained by applying trigonometry to the images shot
with the cameras 1a and 1b. Furthermore, specifically, the
number of chips W can be determined by computing, using
trigonometry, the angles of vision from the cameras 1a and 1b,
the position of the chips W in the images, and a horizontal
distance. ic description will be made below.
In it is assumed that the cameras 1a and 1b and
chips W are present in the same plane dicular to the gaming
table 10. A relational expression between an angle α formed
by a straight line connecting the camera 1a to the center C of
the top chip W and the gaming table 10, an angle β formed by
a straight line connecting the camera 1b to the center C of the
top chip W and the gaming table 10, a distance L n a point
of intersection KR of the straight line connecting the camera
1a to the center C of the top chip W and the gaming table 10
and a point of intersection KL of the ht line connecting
the camera 1b to the center C of the top chip W and the gaming
table 10, and a height H of the stacked chips W is represented
by the following equation (1):
L = H/tan α + H/tan β ... (1)
Here, the distance L and the angles α and β are found by
the following method. The points of intersection KR and KL are
positions where the center C of the top chip W is projected onto
the gaming table 10 as viewed from the angles of view of the
cameras 1a and 1b. Therefore, the points of intersection KR
and KL are obtained by obtaining, by image sing, the
center of the outline of the top chip W in images shot with the
cameras 1a and 1b. Furthermore, by obtaining an image of the
gaming table 10 looked down from immediately above by performing
image processing on the images shot with the cameras 1a and 1b,
the distance L between the points of intersection KR and KL is
ed. Furthermore, if the positions of the points of
intersection KR and KL are known, then since the heights of the
cameras 1a and 1b from the gaming table 10 are fixed, the angles
α and β can be obtained. By the above, the height H of the
stacked chips W can be obtained using the distance L and angles
α and β obtained above and by the following equation (2) which
is a modified version of the above-described on (1):
H = (tan α × tan β)/((tan α + tan β))L ... (2)
Although the above assumes that the cameras 1a and 1b and
the chips W are present in the same plane perpendicular to the
gaming table 10 for simplification of ption, even when
the cameras 1a and 1b and the chips W are not present in the
same plane perpendicular to the gaming table 10, computation
can be performed in the same manner in Given that the
point of intersection of a perpendicular line from the center
C to the gaming table 10 with the gaming table 10 is O, the angle
formed by a straight line connecting the points of ection
O and KR and a straight line connecting the points of
intersection KR and KL is γ, and the angle formed by a straight
line connecting the points of intersection O and KL and the
straight line connecting the points of intersection KR and KL
is δ, though detailed computation is d, the height H is
represented by the following equation (2’):
H = tan α tan β/(tan α cos δ + tan β cos γ)L ... (2’)
By obtaining the height H of stacked chips W by the methods
shown above, the number of chips W with a predetermined
thickness t can be obtained by H/t.
Referring back to the artificial intelligence
tus for deciding a correct result 5 has learned in advance
which one of determination results obtained by the artificial
intelligence apparatuses for determining the number of chips
4a and 4b and the physical measurement determination apparatus
4c which are included in the plurality of chip determination
apparatuses 4 is more likely to be correct for what image based
on which the number of chips W is determined. Then, when the
artificial intelligence apparatus for deciding a correct result
obtains different determination results for the number of
chips W from the cial intelligence apparatuses for
ining the number of chips 4a and 4b and the al
measurement ination apparatus 4c, the artificial
intelligence apparatus for deciding a correct result 5 decides
the correct number of chips W using artificial intelligence.
Upon this on, the artificial intelligence apparatus for
ng a correct result 5 uses images that are used by the
artificial intelligence apparatuses for determining the number
of chips 4a and 4b to determine the number of chips W.
The artificial intelligence apparatus for deciding a
t result 5 may decide the correct number of chips W, taking
into account the positions of the cameras 1a and 1b used by the
game recording apparatus 2. For e, the camera 1a is close
to the betting area 12a and is far from the betting area 12f
(see . Hence, when the artificial intelligence
tus for deciding a correct result 5 determines the number
of chips W stacked in the g area 12a, the artificial
intelligence apparatus for deciding a correct result 5 may
decide the number of chips W obtained as a result of
determination by the artificial intelligence apparatus for
determining the number of chips 4a that uses an image from the
camera 1a, instead of by the artificial intelligence apparatus
for determining the number of chips 4b that uses an image from
the camera 1b, to be correct.
In addition, the artificial intelligence apparatus for
deciding a correct result 5 may decide the correct number of
chips W, taking into account the numbers of pixels obtained from
the cameras 1a and 1b, etc. For example, either one of the
cameras 1a and 1b may be selected by comparing the numbers of
pixels or the degrees of focus which are obtained from the
cameras 1a and 1b. Namely, when focus is ed, an edge
becomes sharp and thus st becomes clear, making it easier
to obtain the correct number of chips W by image processing.
Hence, for example, when different determination results are
obtained for the cameras 1a and 1b, in general, it is highly
likely that a camera that achieves better focus shows the
correct number of chips W.
Alternatively, the artificial intelligence apparatus for
deciding a correct result 5 may decide the correct number of
chips W, taking into account the focal positions of images shot
with the cameras 1a and 1b. For e, it is d that
upon determining the number of chips W stacked in the betting
area 12b, the focus of the camera 1a is located in the betting
area 12b and the focus of the camera 1b is located in the betting
area 12f. In this case, the artificial igence apparatus
for deciding a correct result 5 may decide the number of chips
W obtained as a result of determination by the artificial
igence apparatus for determining the number of chips 4a
that uses an image from the camera 1a, instead of by the
artificial intelligence apparatus for determining the number
of chips 4b that uses an image from the camera 1b, to be correct.
In addition, the artificial intelligence apparatus for
deciding a correct result 5 may decide the correct number of
chips W, taking into account the past results obtained by the
artificial intelligence apparatuses for determining the number
of chips 4a and 4b and the physical measurement determination
apparatus 4c. For example, when the physical measurement
determination apparatus 4c has a higher past correctness rate
than the artificial intelligence apparatuses for determining
the number of chips 4a and 4b, the artificial intelligence
apparatus for deciding a correct result 5 may decide the number
of chips W ed as a result of determination by the al
measurement determination apparatus 4c to be correct.
As such, the artificial intelligence apparatus for
ng a t result 5 can decide a correct result using
various ts. Two or more of the exemplified positions of
the cameras 1a and 1b, numbers of pixels obtained from the
cameras 1a and 1b, focal positions of images, and past results
may be combined, or other information may be further used.
is a flowchart showing a technique for recognizing
chips W. First, the cameras 1a and 1b shoot the state of chips
W, and the game recording apparatus 2 records images
representing the state of chips W (step S1). Subsequently, the
image analysis apparatus 3 analyzes the ed images (step
S2). Then, each of the artificial intelligence apparatuses for
determining the number of chips 4a and 4b and the physical
ement determination apparatus 4c which are included in
the plurality of chip determination apparatuses 4 determines
the number of chips W using an image analysis result (step S3).
Here, if determination s for the number of chips
W which are obtained by the artificial intelligence apparatuses
for ining the number of chips 4a and 4b and the physical
measurement determination apparatus 4c match (YES at step S4),
the determination results are used as the number of chips W.
On the other hand, if the determination results do not match
(NO at step S4), the artificial intelligence apparatus for
deciding a correct result 5 s which one of the
determination results is correct, i.e., decides the correct
number of chips W (step S5).
As such, in the t embodiment, the plurality of chip
determination apparatuses 4 are provided, and furthermore, the
artificial igence apparatus for deciding a t result
is provided. Hence, even when the plurality of chip
determination apparatuses 4 provide different determination
results, the number of chips W can be accurately decided by the
artificial intelligence apparatus for deciding a correct result
Note that the above-described embodiment is to decide the
number of chips W. However, both the type and number of chips
W may be decided. For example, the artificial intelligence
apparatuses for determining the number of chips 4a and 4b may
have learned in advance to determine the type and number of chips
W, and determine both the type and number using images having
been subject to an image analysis. In that case, if the types
of chips W indicated by ination s do not match, the
artificial igence apparatus for deciding a correct result
may further decide the correct type of chips W.
In addition, the chip recognition system may include a
management and control apparatus that controls at least some
of the game recording apparatus 2, the image is apparatus
3, the chip determination apparatuses 4, and the artificial
intelligence apparatus for deciding a correct result 5.
For example, when determination results for the number
(and/or type, the same also applies below) of chips W which are
obtained from the artificial intelligence apparatuses for
determining the number of chips 4a and 4b differ from a
determination result for the number of chips W which is obtained
from the physical measurement determination apparatus 4c, the
ment and control apparatus may output and display
“undetermined” as a determination result.
In addition, when the chip determination apparatuses 4
obtain different determination s for the number of chips
W, the management and control apparatus may e images in
the game recording apparatus 2 to determine whether the
difference in determination result is caused by the stacking
state of chips W stacked on the gaming table 10, and decide the
correct number of chips W based on the determination results
obtained by the respective chip determination apparatuses 4.
The management and control apparatus may have an artificial
intelligence tus function and use the artificial
intelligence tus function for the decision.
The above-described embodiment is described with the aim
of allowing a person of ordinary knowledge in the technical
field to which the present invention belongs to carry out the
t invention. Various ts of the above-described
embodiment can be made as a matter of course by a person skilled
in the art, and the technical idea of the present invention can
also be applied to other ments. Therefore, the present
