Roulette Chip Management with RFID and Multi-Camera Payout Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roulette game management systems face challenges in accurately distinguishing and recognizing the location of betting chips due to limitations in RFID tag reading and camera-based recognition, leading to difficulties in dealer operations and potential fraud detection.
Innovation Solution
A management system that utilizes both RFID tags and cameras to recognize betting chips, employing multiple cameras to capture images from different angles and analyze chip positions, combined with RFID antennas to read chip information, to accurately determine chip locations and calculate payouts, while also detecting fraud through RFID tag readings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are used to read betting chips, then chip identification accuracy is improved, but location recognition capability deteriorates
Solution Approach 1:
The patent combines RFID reading technology with camera-based visual recognition into a unified management system. The RFID reader provides accurate chip identification while the camera system captures images to determine chip locations, merging the strengths of both technologies to simultaneously achieve accurate identification and location recognition.
Solution Approach 2:
The betting chip management system is designed with multi-functionality, where RFID tags provide identification data and camera systems provide location data. The system universally handles both identification and location determination through integrated processing, allowing one system to perform multiple detection functions that were previously separate.
2Difficulty of detecting and measuring
If cameras are used to capture betting chips, then location recognition accuracy is improved, but ability to recognize occluded chips deteriorates
Solution Approach 1:
The system merges camera-based location detection with RFID-based chip identification. While cameras capture images to determine locations of visible chips, RFID readers simultaneously identify all chips including those that may be occluded. The combined system uses RFID data to supplement camera recognition, ensuring complete chip accounting even when chips are partially hidden.
3Measurement precision
If multiple cameras are used to capture images from different angles, then chip location determination accuracy is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple camera systems with RFID reading capabilities into an integrated management system. Rather than using multiple cameras independently, the system combines their visual data with RFID identification data, reducing the need for complex multi-camera coordination while improving location determination accuracy through complementary data sources.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise recognition of betting chip positions and numbers, facilitates efficient dealer operations, reduces fraud risk, and maintains accurate payout calculations, supporting a patron rating system.
Implementation Method 1
The roulette chip has an RFID tag that stores information corresponding to at least its color
Implementation Method 2
at least two cameras, each configured to produce an image or video of the betting area from different oblique upward positions
Data Source
AI summary
The controller is configured to read the RFID tags using the betting area antenna to obtain a first reading result for winning chips remaining after a game result has been determined on a wheel and non-winning chips have been collected by a dealer, capture the winning chips using a plurality of cameras to obtain first images, and analyze the first images using the analyzer to determine a number of image-recognizable winning chips for each color for which occlusion has not occurred in any one the of the first images; and subtract the number of image-recognizable winning chips of each color from a number of winning chips for each color indicated by the first reading result to determine a number of occluded winning chips for each color having occlusion in any of the first images; and calculate a payout amount for each color based on the number of image-recognizable winning chips for each color and a payout multiplier for each of the occluded winning chips.
