Poker cards and recognition device and recognition method thereof

Abstract

The invention discloses poker cards and a recognition device and a recognition method thereof. The poker cards comprise a plurality of card faces with different suits and values. Each card face is provided with a plurality of encoding positions capable of providing different sensitization values, the encoding positions are arranged sequentially, each encoding position is coated with the sensitization values, and values corresponding to the card faces are obtained through calculation according to a preset sequence. In an automatic dealing machine, photovoltaic conversion components are used for converting light signals reflected by sensitization materials on each poker card face into electric signals. A sensitization value line is converted into an electric signal line, and finally recognition of the poker cards is achieved. The recognition method is simple, modification of the existing poker cards is small, and recognition cost is low. Simultaneously, recognition efficiency of the sensitization materials is high, fault rate is low, and the recognition device and the recognition method can effectively improve poker card recognition efficiency and reliability in the automatic dealing machine.

Description

technical field [0001] The invention relates to the technical field of signal detection, in particular to a playing card. In addition, the present invention also relates to an identification device and an identification method for identifying the playing cards. Background technique [0002] Playing cards are a popular entertainment tool and have a large number of users. Nowadays, poker basically requires at least one user to deal the cards to play the game, which is very inconvenient. There are many kinds of poker games on the Internet, which can avoid the disadvantage of frequent card dealing, but many people feel that they can’t find the real game when playing poker games on the Internet, especially poker games such as bridge games that require psychological tactics against opponents . Therefore, the automatic card dealer came into being. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical licensing machine in the prior art....

AI Technical Summary

Problems solved by technology

[0005] The playing cards used in the card dealing machine generally use barcodes or two-dimensional barcodes, and use corresponding identification devices. The problem in use is that printing barcodes will affect the appearance and feel of playing cards, and the cost of identification devices is high. There are also some recognition methods with slow image recognition speed, high cost and poor recognition reliability.
