Abstract

A method, system, and computer readable storage for identifying regions of interest on a casino gaming table. Regions of interest are locations on an image where relevant actions are typically going to occur. For example, locations of betting area region of interest and card area regions of interest are determined so that these areas can be analyzed on a video camera. The analyzed areas can then be used for things such as determining and tracking player betting amounts, determining if the game is being dealt properly (by analyzing the cards dealt to determine if the proper cards are dealt and/or the proper payouts are made).

Claims20

Dependent claims

A method for identifying a region of interest on a casino table, the method comprising:

receiving top-down meta-data for the casino table, wherein the top-down meta-data defines a plurality of regions of interest of the casino table;
capturing with a camera a table image of the casino table, wherein a gaming object is placed on the casino table in one of the plurality of regions of interest;
based on the table image and top-down meta data, defining a homography between the top down meta-data and the table image for the one of the plurality of regions of interest based on the location of the gaming object in the region of interest;
based on the homography, transforming each of the plurality of regions of interest in the top-down meta data to regions of interest in the table image;
and
generating camera meta-data for each of the plurality of transformed regions of interest.
