When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0062] Example 1:

[0063] Reference Figure 1-Figure 4 This embodiment provides a billiard hall management cabinet management method, including the following steps:

[0064] Get the billiard ball return request input by the user;

[0065] According to the billiard ball return request, unlocking information of the return window 130 corresponding to the vacant storage chamber 120 in the billiard ball management cabinet 110 is obtained; wherein a downwardly inclined identification channel 140 is connected between the return window 130 and the storage chamber 120, and the identification channel 140 is wavy;

[0066] Acquire multiple detection images of the target billiard ball 150 when it passes through different positions of the identification channel 140;

[0067] identifying defect information of the target billiard ball 150 according to the plurality of inspection images;

[0068] Obtaining missing quantity information of the returned target billiard balls 150;

[0069] Input defect information and missing quantity information into the preset billing model to obtain order settlement information.

[0070] Currently, cameras can be installed at the return window of the management cabinet to identify whether the returned billiard balls are missing or defective, so as to calculate whether additional fees are incurred based on the missing and defective billiard balls. To improve the recognition accuracy, the existing recognition method requires users to place the billiard balls under the camera in turn and rotate them at different angles according to the prompts to fully collect image information of the billiard balls. The recognition process is relatively slow and the user operation time is long, which affects the user experience. If all the billiard balls are placed in the return window of the management cabinet at once, the bottom surface of the billiard balls cannot be imaged, and the accuracy of billiard ball defect detection is low, resulting in the final fee settlement being lower than the actual amount.

[0071] Therefore, in this embodiment, after recognizing the billiard ball return request input by the user, the unlocking information of the return window 130 corresponding to the vacant storage chamber 120 in the billiard ball management cabinet 110 can be obtained, thereby controlling the automatic opening of the corresponding return window 130 so that the user can put the billiard ball to be returned. Since a downwardly inclined identification channel 140 is connected between the return window 130 and the storage chamber 120, the billiard ball can automatically roll along the identification channel 140 to the storage chamber 120. At the same time, since the identification channel 140 is wavy, the rolling path of the billiard ball in the identification channel 140 is also a wavy curve, so that the angle of the billiard ball continues to change when rolling, so that the multiple detection images of the target billiard ball 150 obtained when passing through different positions of the identification channel 140 can include image information of different surfaces of the target billiard ball 150, thereby improving the adequacy of billiard ball image acquisition, thereby greatly reducing the probability of missed detection, and ultimately improving detection accuracy. At the same time, since the billiard ball The detection process is completed when the ball rolls in the identification channel 140. The user only needs to put the target billiard ball 150 into the return window 130 one by one, which saves the user's time in manually rotating the billiard ball to complete the detection. The time for the billiard ball to pass through the identification channel 140 from the return window 130 and roll to the storage chamber 120 is relatively short, so the interval time between each time the user puts the billiard ball into the return window 130 is also relatively short, thereby improving the efficiency of billiard ball recovery detection. Finally, based on multiple detection images, it is possible to identify whether there is defect information on the target billiard ball 150 and identify the missing quantity information of the returned target billiard ball 150 at the same time. The defect information and the missing quantity information are input into the preset billing model to obtain the order settlement information. The user can complete the payment settlement according to the order settlement information. Therefore, this embodiment achieves the goal of meeting the accuracy of billiard ball defect detection while improving the detection efficiency, thereby taking into account the accuracy of fee settlement and user experience at the same time.

[0072] It should be noted that a ball retrieval window is provided on the other side of the billiard ball management cabinet 110, corresponding to the storage chamber 120, away from the return window 130. After a user scans and pays a deposit, the ball retrieval window automatically opens, allowing the user to remove the billiard balls from the storage chamber 120. A tilted billiard ball tray 190 can be provided within the storage chamber 120, allowing returned billiard balls to automatically roll into the tray 190. Subsequently, when a user retrieves billiard balls, they can remove the tray 190 entirely, place the balls on the table, and then place the empty tray 190 back into the storage chamber 120, making operation convenient and quick. A weight sensor can be provided at the bottom of the storage chamber 120. When a preset weight (i.e., the weight of an empty tray 190) is detected, the ball retrieval window automatically closes. If a user fails to return the tray 190 for an extended period, a voice prompt will be issued to prompt the user to return it as soon as possible, otherwise an additional fee will be incurred. A temporary storage box can be provided on the side wall of the billiard ball management cabinet 110, below the return window 130, to facilitate the placement of returned billiard balls. When it is necessary to calculate the missing number of returned target billiard balls 150, a counter may be provided in the identification channel 140, or a camera may be provided at the top of the storage chamber 120 to identify the total number of returned billiard balls, thereby calculating the missing number.

[0073] As an optional embodiment, the inner bottom of the identification channel 140 is provided with a plurality of arc-shaped protrusions 160 spaced apart along its length direction;

[0074] Acquire multiple detection images of the target billiard ball 150 passing through different positions of the identification channel 140, including:

[0075] Acquire multiple first detection images of the target billiard ball 150 when it passes through different positions of the identification channel 140 based on a top-down perspective of the target billiard ball 150; wherein the first detection images are used to identify the degree of defect of the target billiard ball 150;

[0076] Based on the side view of the target billiard ball 150 , a plurality of second detection images are acquired when the target billiard ball 150 passes through the arc-shaped protrusions 160 at different positions of the identification channel 140 ; ​​wherein the second detection images are used to identify the bounce height of the target billiard ball 150 .

[0077] In this embodiment, in order to further improve the detection accuracy, image acquisition is performed based on different viewing angles, including acquiring multiple first detection images of the target billiard ball 150 when it passes through different positions of the identification channel 140 based on a top-down viewing angle of the target billiard ball 150. In this detection viewing angle, the image acquisition point is located above the target billiard ball 150 and has a certain distance. Therefore, the contour information of the entire target billiard ball 150 and its defect features can be included in the first detection image, thereby accurately identifying the degree of defect of the target billiard ball 150; at the same time, multiple second detection images of the target billiard ball 150 when it passes through the arc-shaped protrusion 160 at different positions of the identification channel 140 are acquired based on a side viewing angle of the target billiard ball 150. Image, when the target billiard ball 150 passes through the arc-shaped protrusion 160, it will bounce to a certain height. If the target billiard ball 150 has a defective part, the bounce height when the defective part just passes through the arc-shaped protrusion 160 is obviously different from the normal bounce height. There are multiple arc-shaped protrusions 160 here, which increases the probability that the defective part of the target billiard ball 150 passes through the arc-shaped protrusion 160. Therefore, the second detection image is used to identify whether the bounce height of the target billiard ball 150 is abnormal, so as to characterize the defect of the target billiard ball 150 from the side, so as to perform supplementary detection on the degree of defect of the target billiard ball 150, thereby reducing the risk of missing detection of billiard ball defect features by relying solely on the first detection image, thereby improving detection accuracy.

[0078] It should be noted that a plurality of recognition cameras 180 may be arranged at corresponding positions on the top and side walls of the recognition channel 140 along the length direction of the recognition channel 140 , so as to capture images of the target billiard balls 150 passing through different positions.

[0079] As an optional implementation, identifying defect information of the target billiard ball 150 based on multiple detection images includes:

[0080] Identify defect features of the target billiard ball 150 based on the plurality of first detection images to obtain a surface defect value M; wherein the defect features include cracks and defects;

[0081] Obtaining a jitter abnormality value H of the target billiard ball 150 based on the plurality of second detection images;

[0082] According to the abnormal value H of the runout and the surface defect value M, the defect degree value Q is obtained and output as defect information; where Q=K1 H+K2 M, K1 is the first adjustment coefficient, and K2 is the second adjustment coefficient.

[0083] In this embodiment, the first detection image can be used to identify whether there are obvious defect features such as cracks and defects in the target billiard ball 150. If there are, the surface defect value M can be quantified based on the corresponding defect features. At the same time, the jitter abnormality value H of the target billiard ball 150 can be obtained by quantitative calculation based on the second detection image. The jitter abnormality value H and the surface defect value M are input into the empirical formula Q=K1 H+K2 M, the defect degree value Q can be quantified and calculated. Since the unit properties and influence degrees of the beat anomaly value H and the surface defect value M are different, they can be adjusted and transformed by the first adjustment coefficient K1 and the second adjustment coefficient K2 respectively, so that the two parameters can be superimposed equally and the calculation is reliable and accurate.

[0084] As an optional embodiment, identifying defect features of the target billiard ball 150 based on the plurality of first detection images to obtain a surface defect value M includes:

[0085] Screening out a first inspection image having defect features;

[0086] Comparing the screened first detection images with each other to determine whether there are at least two first detection images with the same defect characteristics;

[0087] If so, only one first inspection image with the corresponding defect feature is retained;

[0088] If not, based on the remaining first detection images, the crack length value and the defect area value are respectively obtained to obtain the surface defect value M.

[0089] In this embodiment, since the multiple first detection images obtained are collected for different surfaces of the target billiard ball 150, there may be cases where defect features are not identified or the same defect features are repeatedly identified. Therefore, in order to improve the detection accuracy and efficiency, the first detection images with defect features are first screened out (if all first detection images do not identify defect features, the surface defect value M=0 is output), and then the screened first detection images are compared with each other. The similarity algorithm can be combined to compare whether the defect features (including cracks and defects) in each first detection image are the same defect. If so, only one first detection image with the corresponding defect feature is retained. Finally, based on the remaining first detection images, the crack length value and the defect area value are calculated respectively. The weighted sum of the crack length value and the defect area value is used to jointly characterize the surface defect value M. The quantitative calculation is accurate, reliable and representative.

[0090] As an optional embodiment, obtaining the jitter abnormality value H of the target billiard ball 150 according to the plurality of second detection images includes:

[0091] sorting the plurality of second detection images according to the image acquisition time;

[0092] Obtaining a jumping height value of the target billiard ball 150 relative to the bottom of the identification channel 140 in the nth second detection image; wherein n is a positive integer greater than or equal to 1;

[0093] Obtaining the height difference between the bounce height value and the current theoretical height value; wherein the current theoretical height value is the theoretical bounce height value of the complete target billiard ball 150 after passing the arc-shaped protrusion 160 at the corresponding position;

[0094] Determine whether the height difference is greater than a preset difference threshold. If so, output the currently acquired height difference as the jitter abnormality value H. If not, continue to acquire the jitter height value of the target billiard ball 150 relative to the bottom of the identification channel 140 in the n+1th second detection image until the end condition is reached. The end condition is that the jitter abnormality value H is obtained or all the second detection images are identified. If the jitter abnormality value H is still not obtained after all the second detection images are identified, the jitter abnormality value H=0 is output.

[0095] In this embodiment, in order to further improve the detection efficiency, multiple second detection images are sorted according to the image acquisition time. The jumping height value of the target billiard ball 150 relative to the bottom of the identification channel 140 in the first second detection image is first obtained. As the target billiard ball 150 rolls down along the inclined identification channel 140, its inertia becomes larger and larger, and its speed becomes faster and faster. The lower the arc-shaped protrusion 160 it passes, the higher the corresponding bounce height. Therefore, the theoretical height value corresponding to the position of each arc-shaped protrusion 160 is different. Therefore, the height of the jumping height value can be calculated by comparing the height of the current theoretical height value. The height difference is obtained, and it is determined whether the height difference is greater than the preset difference threshold. If so, it indicates that there is an obvious abnormality in the beating height. The currently obtained height difference is output as the beating abnormality value H, and there is no need to identify the next second detection image, which saves detection time and improves detection efficiency. If the first second detection image does not identify the abnormal beating height, the second second detection image is identified, and so on, until the beating abnormality value H is identified or all the second detection images are identified. If the beating abnormality value H is still not obtained after identifying all the second detection images, the beating abnormality value H=0 is output. In summary, this embodiment can reduce repeated recognition calculations, reduce data processing pressure, and thus improve detection efficiency.

[0096] As an optional embodiment, before acquiring multiple detection images of the target billiard ball 150 passing through different positions of the identification channel 140, the method further includes:

[0097] Obtain the number of target billiard balls 150 placed in the return window 130;

[0098] If the number of balls placed is greater than 1, the target billiard ball 150 is controlled to exit the return window 130 and a correct operation prompt message is sent; wherein the correct operation prompt message is used to remind the user that only one billiard ball can be placed into the return window 130 at a time.

[0099] In this embodiment, to ensure accurate identification and detection of each billiard ball, the user is required to place the billiard balls one by one into the return window 130. When the user places two or more billiard balls at a time, the target billiard ball 150 is controlled to exit the return window 130 (the target billiard ball 150 can be pushed out of the return window 130 through a built-in exit mechanism), and correct operation prompt information (such as a voice prompt) is sent to prompt the user to perform the correct operation.

[0100] As an optional implementation, the billing model is expressed as:

[0101] R=R0+(W1 K3 Q+W2 K4 N) R0;

[0102] Wherein, R is the order settlement fee, R0 is the basic fee, N is the missing number of target billiard balls 150, W1 is the first weight coefficient, W2 is the second weight coefficient, and W1<W2, K3 is the third adjustment coefficient, and K4 is the fourth adjustment coefficient.

[0103] In this embodiment, based on the above formula, the basic cost R0 is the normal cost (unit price) incurred by the user playing billiards. Time), if defective information and / or missing quantity information is identified, the corresponding defect degree value Q and / or missing quantity N are calculated, and the additional cost of making up the price difference due to damaged or lost billiard balls is generated by entering the above formula, that is (W1 K3 Q+W2 K4 N) R0, and this additional fee is related to the defect severity value Q and / or the missing quantity N. This makes the deduction more reasonable. Considering the greater economic loss if target billiard ball 150 is lost, a first weight coefficient W1 and a second weight coefficient W2 are set, with W1 < W2, indicating that the additional fee incurred when target billiard ball 150 is missing is higher. When the defect severity value Q and the missing quantity N are both calculated to be 0, then R = R0, and only the base fee R0 needs to be settled.

[0104] As an optional implementation, after inputting the defect information and missing quantity information into a preset billing model to obtain order settlement information, the following steps are further included:

[0105] If the order settlement fee R is greater than the basic fee R0, the storage room 120 after returning the target billiard ball 150 will be marked as abnormal;

[0106] The defect information and / or missing quantity information corresponding to the target billiard balls 150 in the storage chamber 120 after the abnormality mark is sent to the management personnel.

[0107] In this embodiment, if the final order settlement fee R is greater than the basic fee R0, it means that there are billiard ball defects and / or missing billiard balls. At this time, the storage chamber 120 after the target billiard ball 150 is returned can be marked as abnormal, and the marking information (including the storage chamber 120 number and position information) can be obtained. At the same time, the defect information and / or missing quantity information of the corresponding target billiard ball 150 is sent to the management personnel. The defect information includes information such as the defective ball number, defect type, and defect degree, and the missing quantity information includes information such as the missing quantity and missing ball number, so as to facilitate the management personnel to quickly find the corresponding storage chamber 120 and replace the abnormal billiard balls or supplement the missing billiard balls.

[0108] As an optional implementation, after inputting the defect information and missing quantity information into a preset billing model to obtain order settlement information, the following steps are further included:

[0109] The defect information and the missing quantity information are sent to the display screen 170 of the billiard ball management cabinet 110 .

[0110] In this embodiment, by sending defect information and missing quantity information to the display screen 170 of the billiard management cabinet 110, the user can intuitively see the source of the deduction amount to ensure the openness and fairness of the deduction and improve the user experience.
