Video Identification System for Poker Card Removal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional poker game systems face issues with repeated identification of card images due to hesitant or intentional movements of cards during dealing, leading to inefficiencies and potential cheating, causing distrust among casino owners.
Innovation Solution
A method utilizing a video identification system that captures environmental images as a reference sample and continuously compares them with real-time images of the identification zone, ensuring accurate card removal detection by allowing identification only when the card is fully removed, thus preventing repeated image recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the video identification system continuously captures images during card dealing, then card movement can be monitored, but repeated identification of the same card occurs causing inefficiency
Solution Approach 1:
The system performs preliminary action by capturing an environmental image of the identification zone before card dealing begins. This reference image is stored and used for subsequent comparison to determine when a card has been fully removed from the identification zone, preventing repeated identification while maintaining accuracy.
Solution Approach 2:
The system implements feedback by continuously comparing current images of the identification zone with the stored environmental image. When the current image matches the environmental image (indicating the card has been fully removed), the system receives feedback to stop identification and proceed to the next card, thereby preventing repeated identification and improving dealing efficiency.
2Ease of operation
If the dealer moves the card hesitantly or intentionally, then the card may be shaken for cheating purpose, but this causes repeated identification and manual correction is required
Solution Approach 1:
The system continuously compares current images with the environmental image and provides real-time feedback on card removal status. This allows the system to automatically detect when a card has been fully removed from the identification zone, even if the dealer moves the card hesitantly or intentionally, eliminating the need for manual correction and saving time.
3Measurement precision
If the video identification system identifies cards continuously, then all card movements are captured, but the same card image is identified multiple times reducing system utilization
Solution Approach 1:
The system extracts only the essential information needed for identification by comparing current images with the environmental image. It identifies and extracts only the moment when a card has been fully removed from the identification zone, rather than continuously identifying every frame, thereby preventing repeated identification and improving table utilization while maintaining identification precision.

AI summary
A method for preventing repeating identification of card symbols. The method includes obtaining an environmental image of an identification zone as a reference sample before the game starts; a dealer dealing a poker card into the identification zone with the card image identified and continuously obtaining the current image of the identification zone; after the poker card is moved to a card display zone, comparing the current image with the reference sample. If the difference between the current image and the reference sample is smaller than an error allowance value, judging the poker card is fully removed from the identification zone, and proceeding dealing and identification process of next round. If the difference between the current image and the reference sample is greater than an error allowance value, judging the poker card is not fully removed from the identification zone, then the dealer can perform manual process as required.
