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).
Claims18
A method for identifying a region of interest on a casino table, the method, comprising:
- defining template meta-data that quantitatively defines a region of interest on a template image of the casino table, wherein the region of interest defines an area of the casino table where activity occurs on the casino table;
- capturing with a camera a table image of the casino table, wherein a gaming object is placed on the casino table;
- identifying a location of the gaming object on the casino table;
- generating camera meta-data for the region of interest based upon the identifying of the location of the gaming object;
- defining a homography between the template meta-data and the camera meta-data for the region of interest based on the identifying of the gaming object in the region of interest;
- and
- generating camera meta-data for another region of interest based upon the homography.
An apparatus comprising an electronic processor connected to at least one non-transitory computer readable storage medium having instructions stored thereon which when executed by a processor cause the processor to:
- define template meta-data that quantitatively defines template regions of interest on a template image of a casino table, wherein the template regions of interest define areas of the casino table where activity occurs on the casino table;
- capture with a camera a table image of the casino table, wherein objects are placed on the casino table;
- identify locations of the objects on the casino table;
- generate camera meta-data locating a first regions of interest on the at least one table image;
- define a homography between the template meta-data and the camera meta-data for the template regions of interest based on the identifying of the objects on the casino table;
- and
- generate camera meta-data for a second region of interest based upon the homography.
