Casino Table Card Tracking via Optical Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current casino table monitoring systems face challenges in detecting dishonest acts during games, as they rely on tagged cards which are costly to maintain, require constant human observation, and have limitations in covering the entire table area, leading to potential missed moments of fraud and increased operational costs.
Innovation Solution
A casino table system equipped with an imaging device that captures the game surface, detects the presence of cards, and generates trajectory data to monitor card movement, using reference card data for accurate identification and displaying this data in real-time, allowing for the detection of card loss or alteration without the need for tagged cards, thus reducing maintenance and personnel costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tagged cards are used to monitor card position and detect dishonest acts, then real-time detection capability is improved, but maintenance cost and card replacement cost increase significantly
Solution Approach 1:
The patent uses optical imaging to create a digital copy of the card's physical position and trajectory instead of embedding physical tags in the cards. The imaging device captures light reflected from the card surface, generating image data that tracks card movement without requiring any modification to the cards themselves.
Solution Approach 2:
The patent replaces the mechanical/electronic tag system with an optical imaging system. Instead of using RFID tags, NFC tags, or other embedded electronics that require power sources and communication circuits, the system uses non-contact optical fields to detect card position through image capture and processing.
2Reliability
If monitoring personnel continuously observe the monitor to detect dishonest acts, then detection capability is improved, but personnel burden and operational cost increase
Solution Approach 1:
The system performs self-monitoring through automated image processing and analysis. The control unit automatically processes image data from the imaging device, detects card trajectories, identifies suspicious patterns, and generates alerts without requiring continuous human observation. The system serves itself by autonomously detecting dishonest acts and notifying relevant personnel only when necessary.
Solution Approach 2:
The system implements automated feedback loops where image data is continuously processed, card positions are tracked in real-time, and anomalies are automatically detected and reported. This closed-loop system provides continuous monitoring capability without requiring constant human attention, as the system self-corrects and self-monitors through automated feedback mechanisms.
3Device complexity
If camera-based monitoring covers only narrow areas, then device complexity is reduced, but detection coverage and ability to discover dishonest acts decrease
Solution Approach 1:
The patent transitions from two-dimensional camera imaging to three-dimensional spatial tracking by processing image data to extract card trajectories, positions, and movement patterns over time. The system analyzes the temporal dimension of card movement, tracking cards through multiple sequential images to reconstruct their three-dimensional motion paths across the entire table surface.
Solution Approach 2:
The imaging device and control unit serve multiple functions: capturing card positions, tracking trajectories, detecting dishonest acts, and providing real-time alerts. This multi-functional approach eliminates the need for separate sensors, cameras, and processing systems, achieving comprehensive coverage with a unified platform that handles all monitoring tasks.

AI summary
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.
