Abstract:
1. 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: 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.
