[0001] 本发明涉及扑克机技术领域，具体的说，是涉及一种扑克机的翻牌装置及翻牌方法。 [0001] The present invention relates to the technical field of poker machines, and in particular, to a flop device and a flop method of a poker machine.

背景技术 Background technique

[0002] 扑克牌是人们喜爱的一种娱乐项目，玩完一局牌之后需要玩家自己理牌、洗牌和发牌。为了节省发牌的时间，人们发明了自动发牌机来进行发牌，例如公开号为 CN201164714Y的专利文献中公开了一种扑克牌四口发牌机，具有洗牌腔，洗牌腔中央安装由洗牌电机驱动的洗牌差速器，其四周均匀分布四根连接至发牌机构的输送带，该输送带由输送电机驱动，每根输送带一侧安装理牌轮，另一侧安装与理牌轮相配合的挡块，所述理牌轮上安装螺旋形拨杆，发牌机构的输出端安装计数光眼。该发牌机在使用时，将杂乱的牌正面朝下的放入洗牌腔中，通过洗牌差速器、理牌轮、发牌机构后从四个出牌口发出。该发牌机虽然基本上完成了洗牌和发牌的动作，但是仍然无法避免需要玩家自己收拢、整理、翻转正反面朝向不同的扑克牌，导致游戏中劳动强度大，等待时间较长。 [0002] Poker is a kind of entertainment item that people love. After playing a round of cards, players need to manage cards, shuffle cards, and deal cards themselves. In order to save the time of licensing, people invented the automatic card issuing machine to issue cards. For example, the patent document with publication number CN201164714Y discloses a four-port playing card dealer with a card shuffling cavity, which is installed in the center of the card shuffling cavity. The shuffling differential driven by the shuffling motor has four conveyor belts evenly distributed around its periphery. The conveyor belt is driven by the conveyor motor. Each conveyor belt is equipped with a deck wheel on one side and the other. A stopper matched with the licensing wheel, a spiral lever is installed on the licensing wheel, and a counting optical eye is installed on the output end of the licensing mechanism. When the dealer is in use, the messy cards are placed face down into the shuffle chamber, and are issued from the four outlets through the shuffle differential, the deck wheel, and the dealer mechanism. Although the dealer basically completes the shuffling and dealing of cards, it still cannot avoid the player's need to gather, organize, and flip the front and back sides of different playing cards, resulting in high labor intensity and long waiting time in the game.

The flop box 309 is a four-side wall with upper, lower, left and right sides The casing has front and rear penetrating gaps capable of placing playing cards and allowing the playing cards to move in and out. The front and rear penetrating gaps form a playing card passage for moving cards in and out. The front end of the flop box 309 is provided with a card inlet 3091 , The rear end of the flop box 309 is provided with a card outlet 3092, the flop box 309 is rotatably connected to the flop motor 303 installed on the flop base 301, and the flop base 301 is installed at the outlet of the flop box 309 There is a licensing device. After the playing card is pushed out from the card outlet 3092 of the flop mechanism, it enters the licensing device, and the licensing device performs the licensing operation. The identification mechanism includes detection elements and identification elements, specifically:

[0071] 图 6、图 11(a)及图 11 (b) 所示，本实施例中，检测元件包括第一光电感应模块 [0071] As shown in FIG. 6, FIG. 11 (a) and FIG. 11 (b), in this embodiment, the detection element includes a first photoelectric sensor module

314 (在其他实施例中，还可以包括第二光电感应模块，针对这一情况，下述会做详细介绍），该第一光电感应模块 314设置于翻牌盒宽面侧壁的进牌口处，用于对扑克牌在翻牌盒内的长度及位置进行实时检测。当控制器检测到光电感应模块 314发生线路中断时，启动摄像头 315准备图像采集，同时，控制器检测光电感应模块 314发生线路中断的持续时间，并结合扑克牌 a的移动速度确定扑克牌的长度，进而根据扑克牌的长度判断是否存在叠牌问题。为提高叠牌识别的准确度，对摄像头的安装位置设定如下： 314 (In other embodiments, a second photoelectric sensor module may also be included. For this situation, the following will For more details), the first photoelectric sensor module 314 is provided at the entrance of the wide side wall of the flop box to detect the length and position of the playing cards in the flop box in real time. When the controller detects a line interruption of the photoelectric sensor module 314, the camera 315 is started to prepare for image collection. At the same time, the controller detects the duration of the line interruption of the photoelectric sensor module 314, and determines the length of the playing card in combination with the moving speed of the playing card a Then, according to the length of the playing cards, determine whether there is a problem of stacking cards. In order to improve the accuracy of card recognition, the installation position of the camera is set as follows:

[0072] 在扑克牌通道上端侧壁 x上设有一贯通孔 316 , 该贯通孔 316的中心距离扑克牌通道左侧侧壁 y的垂直距离 M的取值范围为：扑克牌符号位置距离其近侧侧边缘的垂直距离 F<M<扑克牌符号位置距离其近侧侧边缘的垂直距离 F+5mm，贯通孔 316的中心距离扑克牌通道的前端边缘的距离 G=扑克牌符号位置距离其前端边缘的垂直距离 R，贯通孔 316的中心距离扑克牌通道的内扑克牌的垂直距离 H的取值范围为： 3mm<H<10mm。摄像头 315通过摄像头支架安装于扑克牌通道的上端侧壁 x贯通孔的正上方，摄像头支架内部为中空成上窄下宽的圆台状，摄像头安装于摄像头支架的顶部。为保证摄像头可采集到有效的牌面图像，摄像头的镜头距离贯通孔的垂直距离 h的取值范围为： 7mm<h<12mm。因本实施例中，翻牌盒可以上下翻转，相对而言，上述贯通孔结构也可以设置在扑克牌通道的下端侧壁上。 [0072] A through hole 316 is provided on the side wall x of the upper end of the playing card channel, and the value range of the vertical distance M of the center of the through hole 316 from the left side wall y of the playing card channel is: the position of the playing card symbol is close to it The vertical distance of the side edge F <M <the vertical distance of the playing card symbol position from its proximal side edge F + 5mm, the center of the through hole 316 is the distance from the front edge of the playing card channel G = the position of the playing card symbol is from its front end The vertical distance R of the edge, and the vertical distance H of the center of the through hole 316 from the inner playing card of the playing card channel are: 3mm <H <10mm. The camera 315 is installed on the upper side wall x through hole of the playing card channel through the camera bracket. The inside of the camera bracket is hollow and forms a round table with a narrow upper and lower width. The camera is installed on the top of the camera bracket. In order to ensure that the camera can collect an effective card image, the vertical distance h of the camera lens from the through hole is in the range of 7mm <h <12mm. Because in this embodiment, the flop box can be turned upside down, relatively speaking, the above-mentioned through hole structure can also be provided on the lower end side wall of the playing card channel.

[0073] 本实施例中，翻牌盒为长、宽、高均不相同且前后贯通的长方体壳体，图 10是本实施例中扑克牌通道（翻牌盒内部空间）的立体结构示意图，如图 10所示，其规格为： [0073] In this embodiment, the flop box is a rectangular parallelepiped case with different lengths, widths, and heights, and penetrates front and back. FIG. 10 is a schematic diagram of a three-dimensional structure of the playing card channel (internal space of the flop box) in this embodiment. As shown in Figure 10, its specifications are:

[0074] 高度 A的取值范围为： 3mm<A<10mm）其最小值意在为摄像头的图像采集留出必要的空间，且可保证扑克牌可从前一装置（一般为分牌装置）中送出后顺利进入翻牌装置，而最大值的设定原因在于：翻牌动作一般较为快速，为防止扑克牌在扑克牌通道内大幅度振动，导致翻牌后的扑克牌难以对准发牌装置两个发牌轮之间的缝隙。 [0074] The value range of height A is: 3mm <A <10mm) The minimum value is intended to reserve the necessary space for the image acquisition of the camera, and can ensure that the playing cards can be used from the previous device (usually a card splitting device) After sending out, it enters the flopping device smoothly, and the reason for setting the maximum value is that the flopping action is generally faster, in order to prevent the playing cards from vibrating greatly in the playing card channel, it is difficult to align the playing cards after the flop with the card issuing device The gap between the two licensing wheels.

[0075] 宽度 B的取值范围为：扑克牌宽度 Ll+lmm<B<扑克牌宽度 Ll+5mm，最小值的设定是为了避免扑克牌与扑克牌通道的侧壁发生不必要分剐蹭。最大值的设定是防止扑克牌在扑克牌通道内移动的过程中发生倾斜，影响下一装置的进牌秩序。 [0075] The value range of the width B is: playing card width Ll + lmm <B <playing card width Ll + 5mm, the minimum value is set to avoid unnecessary separation between the playing card and the side wall of the playing card channel. The setting of the maximum value is to prevent the playing cards from tilting during the movement in the playing card channel, which affects the card rank of the next device Order.

[0076] 长度 C的取值范围为： 1.1*扑克牌的长度 L2<C<1.5*扑克牌的长度 L2，最小值的设定是一方面是为了保证扑克牌完全进入到翻牌装置后才执行翻牌动作，另一方面，当光电感应模块为两个时，给出足够的判断长度的间隔，最大值的设定原因在于：一方面， L过长也会导致翻牌装置占用较大的空间，不利于扑克机向小型化、紧凑化发展；另一方面，为提高扑克牌的整理速度，应尽量减少扑克牌的不必要行程，因此缩短 L的长度。 [0076] The value range of the length C is: 1.1 * Length of playing cards L2 <C <1.5 * Length of playing cards L2, the minimum value is set on the one hand to ensure that the playing cards fully enter the flop device The flop action is performed. On the other hand, when there are two photoelectric sensor modules, a sufficient interval for judging the length is given. The reason for setting the maximum value is: On the one hand, too long L will also cause a large occupancy of the flop device The space is not conducive to the development of small and compact poker machines; on the other hand, in order to increase the speed of playing cards, the unnecessary travel of playing cards should be reduced as much as possible, so the length of L is shortened.

[0077] 基于上述本实施例的翻牌方法为： [0077] The flop method based on the above-mentioned embodiment is:

[0078] 1）当扑克牌前端由扑克牌通道的进牌口进入翻牌装置时，第一光电感应模块发生线路中断，控制器启动摄像头。 [0078] 1) When the front end of the playing card enters the flopping device from the card inlet of the playing card channel, a line interruption occurs in the first photoelectric sensor module, and the controller activates the camera.

[0079] 2）当扑克牌的符号位置移动至摄像头的正下方时，摄像头采集扑克牌的牌面图像。 [0079] 2) When the symbol position of the playing card moves directly under the camera, the camera collects the image of the playing card.

[0080] 3）控制器对牌面图像进行处理识别，判断扑克牌的正反面；具体的：控制器内的图像处理模块对牌面图像进行信息提取，判断是否存在符号，若存在符号，则判断为正面，反之，则为反面。 [0080] 3) The controller processes and recognizes the card surface image to determine the front and back sides of the playing card; specifically: the image processing module in the controller extracts information from the card surface image to determine whether there is a symbol, if there is a symbol, then The judgment is positive, otherwise, it is negative.

[0081] 4）若扑克牌的牌面朝向与应输出牌面朝向不一致，则启动翻牌电机，当扑克牌完全进入到扑克牌通道内后，执行翻牌动作。 [0081] 4) If the face direction of the playing card is not consistent with the face direction of the card face to be output, the flop motor is started, and when the playing card is completely entered into the playing card channel, the flop action is performed.

[0082] 5）将扑克牌推送至下一处理装置。 [0082] 5) Push the playing cards to the next processing device.

[0083] 此外，步骤 1）中，第一光电感应模块发生线路中断时，控制器同时开始对扑克牌的长度进行检测，并根据该扑克牌的长度判断是否存在叠牌问题；具体的 [0083] In addition, in step 1), when a line interruption occurs in the first photoelectric sensor module, the controller simultaneously starts to detect the length of the puck card, and judges whether there is a card overlap problem according to the length of the playing card; specific

[0084] 控制器根据第一光电感应模块发生线路中断的时间，结合扑克牌的移动速度，确定进入翻牌盒的扑克牌的实际长度，若该实际长度大于扑克牌的理论长度，则判断为存在叠牌问题； [0084] The controller determines the actual length of the playing card entering the flop box according to the time when the first photoelectric sensor module has a line interruption, combined with the moving speed of the playing card, and if the actual length is greater than the theoretical length of the playing card, it is determined as There is a problem of overlapping cards;

[0085] 若存在叠牌问题，则启动送牌电机反向转动，进而驱动走牌轮回转，带动扑克牌回退，将扑克牌退回至翻牌装置的前一装置中。 [0085] If there is a problem of stacking cards, the card feeding motor is started to rotate in reverse, thereby driving the deck to rotate, driving the playing cards back, and returning the playing cards to the previous device of the flop device.

[0086] 结合上述技术方案，本实施例的具体动作流程为： [0086] With reference to the above technical solution, the specific action flow of this embodiment is:

[0087] 参见图 6，扑克牌 a自进牌口 3091进入翻牌盒 309，第一光电感应模块 314发生线路中断的时间，控制器启动摄像头 315 , 同时开始计时，检测扑克牌在扑克牌通道内的具***置，当扑克牌 a到达摄像头 315的正下方时，摄像头 315对扑克牌 a进行牌面图像的采集，此时，第一走牌轮 316位于翻牌盒 309上方，第二走牌轮 317 推送扑克牌 a向扑克牌通道内移动，若扑克牌正对摄像头 315的一面与预设不一致，则当扑克牌完全进入翻牌装置且不存在叠牌问题时，控制器控制翻牌电机 303 驱动翻牌盒 309翻转 180°，使扑克牌翻面；翻牌完毕后，送牌电机驱动走牌轮带动扑克牌向出牌口 3092方向移动。 [0087] Referring to FIG. 6, the playing card a enters the flop box 309 from the card entrance 3091, and the first photoelectric sensor module 314 generates a line When the road is interrupted, the controller starts the camera 315 and starts timing at the same time to detect the specific position of the playing card in the playing card channel. When the playing card a reaches directly below the camera 315, the camera 315 performs a card image on the playing card a Collecting, at this time, the first roulette wheel 316 is located above the flop box 309, and the second roulette wheel 317 pushes the playing card a to move into the playing card channel, if the side of the playing card facing the camera 315 is not consistent with the preset, then When the playing cards completely enter the flopping device and there is no problem of folding cards, the controller controls the flopping motor 303 to drive the flopping box 309 to turn 180 ° to turn the playing cards; after the flopping, the card feeding motor drives the walking wheel The playing cards are driven to move toward the card outlet 3092.

[0088] 控制器根据扑克牌的进入扑克牌通道的时间结合扑克牌的移动速度，计算扑克牌的长度，若扑克牌的检测长度大于其理论长度，则判断为存在叠牌问题。 [0088] The controller calculates the length of the playing card according to the time when the playing card enters the playing card channel combined with the moving speed of the playing card. If the detected length of the playing card is greater than its theoretical length, it is determined that there is a card overlap problem.

[0089] 若控制器检测到存在叠牌问题，则走牌电机 318反向转动，驱动与扑克牌贴合的第二走牌轮 317回转，将扑克牌退回至前一装置中。 [0089] If the controller detects that there is a card stacking problem, the card-playing motor 318 reversely rotates, driving the second card-playing wheel 317 attached to the playing cards to rotate, returning the playing cards to the previous device.

[0090] 如图 8和图 10所示，翻牌盒 309的出牌口 3902位置安装有发牌装置的主动轮 401 和限位轮 402, 主动轮 401经齿轮传动产生旋转，限位轮 402固定不动，并与主动轮配合形成只能通过一张牌的间隙。当牌进入主动轮 401和限位轮 402的间隙时，如果有牌重叠的现象，能再次对扑克牌进行单张分离，保证发牌张数准确。 [0090] As shown in FIG. 8 and FIG. 10, a driving wheel 401 and a limit wheel 402 of the card issuing device are installed at the outlet 3902 of the flop box 309, the driving wheel 401 generates rotation through gear transmission, and the limit wheel 402 It is fixed and cooperates with the driving wheel to form a gap that can only pass through a card. When the card enters the gap between the driving wheel 401 and the limit wheel 402, if there is a phenomenon of card overlap, the playing cards can be separated again, to ensure that the number of cards dealt is accurate.

[0091] 下面，以翻牌装置需输出扑克牌正面朝下为例，本实施例翻牌装置的具体工作过程为： [0091] Next, taking the example that the flop device needs to output playing cards face down as an example, the specific working process of the flop device in this embodiment is:

[0092] 参见图 6 , 若进入翻牌盒的扑克牌为正面朝上，则翻牌电机 303驱动翻牌盒 309 顺时针或逆时针转动 180°，此时扑克牌正面朝下，并且翻牌盒 309朝下一侧的滚动轮会压在与传动机构连接的两个传动轮上，这样这个滚动轮就相当于向下压紧，滚动轮会带动与之连接的第二走牌轮 317向下压紧，这样走牌轮深入到翻牌盒内将扑克牌压住，这时启动送牌电机，如图 9所示，送牌电机 318驱动与之连接的传动机构，翻牌盒 309两侧的传动机构通过传动轴连接，所以两侧的传动机构会同时运动并带动两侧的传动轮转动，其中，上面的两个传动轮带动被其压紧的滚动轮转动，该滚动轮通过中心轴带动第二走牌轮转动，扑克牌会在摩擦力的作用下向前运动，被送出出牌口 3902，如图 7所示，进入下一处理装置中。 [0092] Referring to FIG. 6, if the playing card entering the flop box is face up, the flop motor 303 drives the flop box 309 to rotate 180 ° clockwise or counterclockwise, at this time the playing card is face down and the flop The scroll wheel on the downward side of the box 309 will press on the two transmission wheels connected to the transmission mechanism, so that this scroll wheel is equivalent to pressing down, and the scroll wheel will drive the second deck wheel 317 connected to it Press down tightly, so that the walking wheel goes deep into the flop box to hold down the playing cards. At this time, the card feeding motor is started. As shown in FIG. 9, the card feeding motor 318 drives the transmission mechanism connected to it, and the flop box 309 two The transmission mechanisms on the sides are connected by a transmission shaft, so the transmission mechanisms on both sides will move simultaneously and drive the transmission wheels on both sides to rotate. Among them, the upper two transmission wheels drive the rolling wheel pressed by it to rotate, and the rolling wheel passes through the center. The shaft drives the second playing wheel to rotate, and the playing cards will move forward under the action of friction and be sent out of the card slot 3902, as shown in FIG. 7, into the next processing device.

[0093] 若扑克牌为翻面朝上，如图 9 , 送牌电机 318驱动与之连接的传动机构，使第一走牌轮 316转动，直接将扑克牌推送至翻牌盒 309外。 [0094] 上述过程中，对扑克牌正反面的具体方法为：识别机构中的摄像头对扑克牌进行图像采集，并将采集到的扑克牌图像传输至扑克机的图像处理模块，图像处理模块对扑克牌的正反面进行识别，具体可参见寇永军于 2007年在湖南大学校刊上发表的名称为“图像识别在发牌机上的应用研究”的硕士论文，该论文中，对扑克牌的识别过程包括如下步骤： [0093] If the playing cards are turned upside down, as shown in FIG. 9, the card sending motor 318 drives the transmission mechanism connected thereto to rotate the first playing wheel 316, and directly push the playing cards out of the flop box 309. [0094] In the above process, the specific method for the front and back of the playing card is: the camera in the identification mechanism collects the image of the playing card, and transmits the collected playing card image to the image processing module of the poker machine, the image processing module Recognize the front and back of playing cards. For details, please refer to Kou Yongjun's master thesis titled "The Application Research of Image Recognition on Dealing Machines" published in the Journal of Hunan University in 2007. In this paper, the recognition process of playing cards includes The following steps:

[0095] 1）图像预处理 [0095] 1) Image preprocessing

[0096] 这一过程主要包括对扑克牌图像位置校正，原因在于：摄像头实时采集到的图像中，扑克牌并不一定为正方的，在多数情况下，扑克牌与整个图像的边缘形成一定的倾斜角度，因此，在扑克牌识别之前，必须先对其进行倾斜校正和定位。 [0096] This process mainly includes the correction of the position of the playing card image, the reason is that: in the image collected by the camera in real time, the playing card is not necessarily square, in most cases, the playing card and the edge of the entire image form a certain The inclination angle, therefore, before playing cards are identified, the inclination must be corrected and positioned.

[0097] 对于整个扑克牌识别***来说，扑克牌识别精确度的高低主要取决于扑克牌的倾斜校正与定位精确度高低。扑克牌形状为一矩形，扑克牌是否倾斜可以以扑克牌的物理边缘是否与图像边缘倾斜为准则，若扑克牌的物理边缘与图像边缘呈 0或 90度（平放或正放），则扑克牌没有发生倾斜，反之，则存在倾斜。 [0097] For the entire playing card recognition system, the level of playing card recognition accuracy mainly depends on the playing card tilt correction and positioning accuracy. The shape of the playing card is a rectangle. Whether the playing card is inclined can be based on whether the physical edge of the playing card is inclined to the edge of the image. If the physical edge of the playing card is 0 or 90 degrees from the image edge (horizontal or forward), then the poker There is no tilt of the card, otherwise, there is tilt.

[0098] 根据以上分析的特点，可以利用 Hough变换和边缘检测结合的方法实现扑克牌的倾斜校正与定位： [0098] According to the characteristics of the above analysis, the combination of Hough transform and edge detection can be used to achieve the tilt correction and positioning of playing cards:

[0099] L对扑克牌进行边缘检测； [0099] L edge detection for playing cards;

[0100] ii.将扑克牌内部的复杂线条进行模糊化处理； [0100] ii blur the complex lines inside the playing cards;

[0101] iii.采用 Hough变换校正扑克牌的倾斜角度。 [0101] iii. Use the Hough transform to correct the inclination angle of the playing cards.

[0102] 其中步骤 i中，可采用中心坐标投影法对扑克牌进行边缘检测。 [0102] In step i, the center coordinate projection method may be used to detect the edges of the playing cards.

[0103] 具体的，对一张完整的图像，在图像捕获和预处理后得到欲识别有效区域的图像，对该图像做中心坐标垂直投影，得到垂直投影结果，据此可得到标识区域应为由左下角点到右上角点决定的矩形区域面积为扑克牌的整体图像。 [0103] Specifically, for a complete image, after image capture and pre-processing, an image of an effective area to be identified is obtained, and the center coordinate is vertically projected on the image to obtain a vertical projection result. According to this, the identification area should be The area of the rectangular area determined from the lower left corner to the upper right corner is the overall image of the playing card.

[0104] 对于常规字符的扑克牌，如图 11所示，在原图像中引入 p、 0和 L三个参数，通过 p和 0参数的变化可以累加出对应 L的值（直线长度），讲检测出来的最大的 L 所对应的倾斜角 0视为扑克牌的倾斜，但如 J、 Q、 K和 JOKER，由于图案边缘复杂性的原因， Hough变换后就会产生一些非纸牌物理边缘而长度超过物理边缘的线条，此时，该线条对应的倾斜角 0就不是纸牌与图像所成的真实倾斜角度。 [0105] 这些复杂线条信息的存在，会对纸牌物理边缘的确认产生十分大的影响，因此，在 Hough变换之前，必须采取一些操作，最大程度地去除这些复杂的边缘信息的同时，保留纸牌的物理边缘信息。例如，可以在经过边缘检测的前提下，通过形态学闭操作把纸牌内部的复杂线条模糊化，然后再对模糊化后的图像进行边缘检测。 [0104] For playing cards of conventional characters, as shown in FIG. 11, three parameters of p, 0 and L are introduced in the original image, and the value of L (line length) can be accumulated through the change of the p and 0 parameters. The inclination angle 0 corresponding to the largest L is regarded as the inclination of playing cards, but for J, Q, K and JOKER, due to the complexity of the pattern edges, after the Hough transform, some non-card physical edges will be generated and the length exceeds For a line on the physical edge, at this time, the tilt angle 0 corresponding to the line is not the true tilt angle formed by the card and the image. [0105] The presence of these complex line information will have a great influence on the confirmation of the physical edge of the card. Therefore, before the Hough transform, some operations must be taken to remove these complex edge information to the greatest extent while retaining the card ’s Physical edge information. For example, on the premise of edge detection, the complex lines inside the card can be blurred by morphological closing operation, and then edge detection can be performed on the blurred image.

[0106] 2）特征提取 [0106] 2) Feature extraction

[0107] 由于纸牌具有很多的特征，如字符特征，花形特征，图案特征，颜色特征等，不同的纸牌具有不同的特征。根据特征的组合，可以产生出 54种不同的纸牌，必须在待识别的纸牌中提取它所具备的相关特征。具体的提取过程如下： [0107] Since playing cards have many characteristics, such as character characteristics, flower-shaped characteristics, pattern characteristics, color characteristics, etc., different playing cards have different characteristics. According to the combination of features, 54 different kinds of cards can be produced, and the relevant characteristics of the cards to be recognized must be extracted from the cards to be recognized. The specific extraction process is as follows:

[0108] 由于纸牌内部的图案较复杂，对其操作运算量较大，不以其作为识别的特征。 [0108] Since the internal pattern of the playing card is more complicated, the amount of operation calculation on it is large, and it is not used as a recognition feature.

而字符和花形特征结构较为简单，易于操作，所以应该在纸牌中提取字符与花形的特征，并以这两个特征识别出纸牌。 The character and flower-shaped feature structures are relatively simple and easy to operate, so the characters and flower-shaped features should be extracted from the playing cards, and the playing cards should be recognized by these two features.

[0109] 在纸牌倾斜校正与定位后，根据纸牌的固有属性，可以大概地定位出纸牌上字符与花形的位置，然后把字符与花形粗略提取出来。 [0109] After the tilt correction and positioning of the card, according to the inherent properties of the card, the position of the character and flower shape on the card can be roughly located, and then the character and flower shape are roughly extracted.

[0110] 提取出字符与花形的大概位置后，必须对提取出的图像进行二值化，进一步提取特征。 [0110] After extracting the approximate positions of the character and the flower shape, the extracted image must be binarized to further extract features.

[0111] 在字符和花形粗略定位并且二值化之后，有时会残留一些很长边缘信息。这些边缘信息多数来自于纸牌本身的图案边缘或背景残留。由于这些线条多数与字符和花形的颜色相近，因此在图像二值化之后仍然会保留下来。这些多余的边缘信息给特征的正确提取带来了很大的影响，所以在字符分割之前去除这些干扰是必要的。 [0111] After characters and flower shapes are roughly positioned and binarized, sometimes some very long edge information remains. Most of the edge information comes from the pattern edge or background residue of the card itself. Since most of these lines are similar to the colors of characters and flowers, they will remain after the image is binarized. The extra edge information has a great influence on the correct feature extraction, so it is necessary to remove these interferences before character segmentation.

[0112] 这些边缘信息都具有连续不跳变的特性，因此可以利用这个特性对二值化图像进行扫描，当出现超过一定长度不跳变的线条，把它视为干扰信息，并且把它去除。 [0112] These edge information have the characteristics of continuous non-jumping, so this feature can be used to scan the binary image, when there is a line that does not jump over a certain length, it is regarded as interference information, and it is removed .

[0113] 在其他实施例中，还可以采用字符识别的方式，具体如下： [0113] In other embodiments, character recognition may also be used, as follows:

[0114] 纸牌中有字符和花形两种字符，字符包括 A、 2、 3、 4、 5、 6、 7、 8、 9、 10、 J 、 Q、 K、 JOKER十四种；而花形包括：黑桃、红桃、梅花和方片四种。不论采用结构特征还是统计特征的匹配方法方法，均需要与一个***预存的标准符号模板库进行匹配。 [0114] There are two types of characters in the playing card and the flower shape, the characters include A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, JOKER; and the flower shape includes: Four types of spades, hearts, plums and square slices. Whether the matching method of structural features or statistical features is used, it needs to be pre-stored with a standard symbol of the system Template library for matching.

[0115] 结构特征匹配的识别准确率较高，但是运算量十分大，用于符号结构较复杂的识别；统计特征匹配识别准确率相对较低，但运算量少，适用于结构简单的符号识别。纸牌只有 14个字符和 4个花形符号，而且结构较简单，这里选用统计特征匹配。 [0115] The recognition accuracy of structural feature matching is high, but the amount of calculation is very large, and it is used for the recognition of complex symbol structures; the accuracy of statistical feature matching recognition is relatively low, but the calculation amount is small, which is suitable for symbol recognition with a simple structure . The playing card has only 14 characters and 4 flower-shaped symbols, and the structure is relatively simple. Here, the statistical characteristics are used for matching.

[0116] 对于不同的符号，其投影均不相同。 [0116] For different symbols, their projections are different.

[0117] 因此，可以利用待识别符号投影与模板中各符号的投影求均方差，选择均方差最小（即与待识别符号投影偏离最小）所对应的模板符号作为识别结果。 [0117] Therefore, the mean square deviation can be obtained by using the projection of the symbol to be recognized and the projection of each symbol in the template, and the template symbol corresponding to the smallest mean square deviation (that is, the smallest deviation from the projection of the symbol to be recognized) can be selected as the recognition result.

[0118] 在符号中，由于 JOKER信息像素所占数目较多，因此先对其确认。在匹配前先对符号进行一定的结构性膨胀，由于 JOKER具有多个字符，在膨胀后非零像素增加的数量定会大大的大于其它纸牌。这里设置一个临界值，当某待识别纸牌特征像素数量大于此临界值时把这张纸牌识别为 JOKER，小于临界值再与其他模板进行匹配，这样就可以不需要额外加入 JOKER模板，同时也一定程度下提高了***的识别效率。 [0118] In the symbol, since the JOKER information pixels occupy a large number, they are first confirmed. Before the match, a certain structural expansion of the symbol is performed. Since JOKER has multiple characters, the number of non-zero pixels increased after expansion will be much larger than other cards. Set a threshold here. When the number of characteristic pixels of a card to be recognized is greater than this threshold, the card will be recognized as JOKER. If it is less than the threshold, it will be matched with other templates, so that there is no need to add additional JOKER templates. To a certain extent, the recognition efficiency of the system is improved.

[0119] 3）正反面判断 [0119] 3) Positive and negative judgment

[0120] 根据上述过程，若纸牌的字符特征、花形特征、图案特征、颜色特征字符或花形可与***预存的标准符号模板库中的任一模板相匹配，则判断所采集到扑克牌为正面朝向摄像头。 [0120] According to the above process, if the character feature, flower feature, pattern feature, color feature character or flower feature of the playing card can match any template in the standard symbol template library pre-stored in the system, the collected playing cards are judged to be positive Facing the camera.

[0121] 实施例二： [0121] Embodiment 2:

[0122] 与实施例一的不同在于：检测元件还包括第二光电感应模块，该第二光电感应模块设置于翻牌盒 309宽面侧壁的出牌口 3092方向，第一光电感应模块与第二光电感应模块之间的垂直距离 N的取值范围为： [0122] The difference from the first embodiment is that: the detection element further includes a second photoelectric sensor module, the second photoelectric sensor module is disposed in the direction of the card outlet 3092 on the wide side wall of the flop box 309, the first photoelectric sensor module and The range of the vertical distance N between the second photoelectric sensor modules is:

[0123] 扑克牌的长度 L2<N<扑克牌的长度 L2+5mm，若第一光电感应模块和所述第二光电感应模块均发生线路中断，则判断为存在叠牌问题，原理在于 :当出现叠牌问题时，扑克牌的长度一般明显长于扑克牌的理论长度，将 N的长度设置在这个范围内，叠牌在通过翻牌盒 309时，会在一个时间段内，第一光电感应模块和第二光电感应模块的光路均会被扑克牌阻挡，出现线路阻断。 [0123] The length of playing cards L2 <N <the length of playing cards L2 + 5mm, if both the first photoelectric sensor module and the second photoelectric sensor module have a line interruption, it is determined that there is a card overlap problem, the principle lies in: When there is a problem with the deck of cards, the length of the playing cards is generally significantly longer than the theoretical length of the playing cards. Set the length of N within this range. When the deck of cards passes through the flop box 309, the first photoelectric sensor will Both the optical path of the module and the second photoelectric sensor module will be blocked by playing cards, and the line will be blocked.

[0124] 针对于本实施例的翻牌方法为： [0125] SOI：当扑克牌前端由扑克牌通道的进牌口进入翻牌装置时，第一光电感应模块发生线路中断，控制器启动摄像头。 [0124] The flop method for this embodiment is: [0125] SOI: When the front end of the playing card enters the flopping device from the card inlet of the playing card channel, a line interruption occurs in the first photoelectric sensor module, and the controller starts the camera.

[0126] S02：当扑克牌的符号位置移动至摄像头的正下方时，摄像头采集扑克牌的牌面图像。 [0126] S02: When the symbol position of the playing card moves directly under the camera, the camera collects the image of the playing card.

[0127] S03：控制器对牌面图像进行处理识别，判断扑克牌的正反面，具体的：控制器内的图像处理模块对牌面图像进行信息提取，判断是否存在符号，若存在符号，则判断为正面，反之，则为反面。 [0127] S03: The controller processes and recognizes the card surface image to determine the front and back sides of the playing card. Specifically: the image processing module in the controller extracts information from the card surface image to determine whether there is a symbol, if there is a symbol, then The judgment is positive, otherwise, it is negative.

[0128] S04：若扑克牌的牌面朝向与应输出牌面朝向不一致，则启动翻牌电机，当扑克牌完全进入到扑克牌通道内后，执行翻牌动作。 [0128] S04: If the face direction of the playing cards is not consistent with the face direction of the cards to be output, the flop motor is started, and when the puck is completely entered into the playing card channel, the flop action is performed.

[0129] S05：将扑克牌推送至下一处理装置。 [0129] S05: Push the playing cards to the next processing device.

[0130] 步骤 S01中，第一光电感应模块发生线路中断，控制器对扑克牌的长度进行检测，并根据该扑克牌的长度判断是否存在叠牌问题；具体的，若位于扑克牌通道的进牌口处的第一光电感应模块与位于扑克牌通道的出牌口方向侧的第二光电感应模块同时发生线路中断，则判断为存在叠牌问题。 [0130] In step S01, a line interruption occurs in the first photoelectric sensor module, the controller detects the length of the playing cards, and determines whether there is a card overlap problem according to the length of the playing cards; When the first photoelectric sensor module at the card slot and the second photoelectric sensor module located at the outlet side of the playing card channel are simultaneously disconnected, it is determined that there is a card overlap problem.

[0131] 若存在叠牌问题，则启动送牌电机反向转动，进而驱动走牌轮回转，带动扑克牌回退，将扑克牌退回至翻牌装置的前一装置中。 [0131] If there is a problem of card folding, the card feeding motor is started to rotate in the reverse direction, thereby driving the deck to rotate, driving the playing cards back, and returning the playing cards to the previous device of the flop device.
