Abstract
The present invention is to provide a casino table capable of adequately determining whether a dishonest act is committed on a card arranged on a casino table while reducing a maintenance cost, a personnel cost, etc., by using a normal card not containing the tag, etc. A game surface is imaged by an imaging device, the presence of the card placed on the game surface is detected from image data produced by an imaging signal issued from the imaging device, and trajectory data of the card placed on the game surface is produced.
Claims11
A casino table, comprising:
- a game surface on which a game is played;
- an imaging device imaging the game surface and issuing an imaging signal;
- and
- a monitoring control unit monitoring the game based on the imaging signal issued from the imaging device, wherein
- the monitoring control unit comprises:
- a controller executing the following processing (1-1-1) to (1-1-3) of:
- (1-1-1) imaging the game surface by the imaging device;
- (1-1-2) detecting the presence of a card placed on the game surface from image data produced by the imaging signal issued from the imaging device;
- and
- (1-1-3) producing trajectory data of the card placed on the game surface, and
- a storing means into which data used for these processing is stored,
- wherein the trajectory data include a plurality of predetermined times and a plurality of position data of the card that are detected for the predetermined times, respectively and are associated with the predetermined times, respectively,
- wherein the trajectory data is associated with identification information of the card, and
- wherein the processing of (1-1-2) comprises processing of:
- producing outline data by extracting an outline of an object imaged by the imaging device by the imaging signal;
- extracting a plurality of line segments from the outline data;
- registering two line segments that are substantially in parallel and has substantially the same in length from among the line segments, as a parallel line pair;
- and
- determining two parallel line pairs corresponding to four sides of a rectangle for a card,
- wherein the processing of (1-1-2) further comprises processing of:
- when the two parallel line pairs corresponding to the four sides are not present, determining whether one parallel line pair and one line segment for configuring three sides of the rectangle are present;
- and
- forming the rectangle by the one parallel line pair and the one line segment when the one parallel line pair and the one line segment for configuring three sides of the rectangle are present.

- and
- a monitoring control unit monitoring the game based on the imaging signal issued from the imaging device, wherein
- the monitoring control unit comprises:

- (5-1-1) producing outline data by extracting an outline of an object imaged by the imaging device by the imaging signal issued from the imaging device;
- (5-1-2) extracting a plurality of line segments from the outline data;
- (5-1-3) registering two line segments that are substantially in parallel and has substantially the same in length from among the line segments, as a parallel line pair;
- (5-1-4) determining two parallel line pairs corresponding to four sides of a rectangle for a card;
- (5-1-5) storing, as card information, a position of a vertex of the rectangle into the storing means, and
- (5-1-6) producing trajectory data indicating a trajectory of the card by executing the processing of (5-1-1) to (5-1-5) at least once, and
- a storing means into which data used for these processing is stored,
- wherein the trajectory data include a plurality of predetermined times and a plurality of position data of the card that are detected for the predetermined times, respectively and are associated with the predetermined times, respectively,
- wherein the trajectory data is associated with identification information of the card, and
- wherein the controller further executes the following processing of:
- when the two parallel line pairs corresponding to the four sides are not present, determining whether one parallel line pair and one line segment for configuring three sides of the rectangle are present;
- and
- forming the rectangle by the one parallel line pair and the one line segment when the one parallel line pair and the one line segment for configuring three sides of the rectangle are present.
