Description

Technical Field

[0001] The present invention relates to the field of information processing technology, and in particular to a method and system for storing and retrieving wheel hub information. Background Art

[0002] Automobile wheels are critical components that directly impact high-speed driving safety and comfort. The eccentricity between the bolt hole pitch circle center and the center hole center is a key parameter affecting wheel hub quality. Rapidly and accurately measuring these eccentricities on automated production lines is a significant technical challenge directly impacting wheel hub quality. Currently, this eccentricity is measured manually using specialized hole-to-hole distance (PCD) gauges, which is inefficient and inaccurate.

[0003] Typically, after completing a TPMS diagnosis or upgrade, especially after replacing or removing a tire, the user will balance the tire and reinstall it. At this point, the user needs to know some wheel parameters, such as the outer diameter, inner diameter, and width for dynamic balancing, and the bolt hole diameter and PCD for installation. Typically, users use a special ruler to manually measure or consult the car manual to obtain these parameters, which is very inconvenient in actual operation.

[0004] Machine vision uses computers to realize human visual functions, that is, using machines to replace human eyes to make measurements and judgments. Geometric measurement technology based on machine vision has the advantages of non-contact, good flexibility, high precision, high speed, high automation and intelligence. The measurement method based on machine vision does not affect the surface characteristics of the object to be measured and can achieve high measurement accuracy. The Chinese patents "Method for detecting the shape and position parameters of wheel hub mounting holes based on image recognition" and "A vehicle wheel hub detection device based on CCD imaging technology" use machine vision methods to measure the parameters of automobile wheel hub bolt holes, center holes and bolt hole pitch circle diameters, but do not include the measurement of the eccentricity of the bolt hole pitch circle center and the center hole center.

[0005] However, if the wheel hub is directly measured and inspected using machine vision, the matching between the measured value and the actual value will be poor. However, if the wheel hub information is directly stored and the parameter value of the wheel hub is obtained based on the wheel hub information, the problem of how to quickly and accurately determine the wheel hub parameters can be solved. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention discloses a method for storing and retrieving wheel hub information, the method comprising the following steps:

[0007] Step 1: Build a database to store wheel hub information, the database including wheel hub appearance image features and wheel hub parameters corresponding to vehicle models, and build a wheel hub information retrieval platform. User terminal devices send a request to access the database storing wheel hub information through the platform and access the database. The wheel hub parameters include bolt hole, center hole and bolt hole pitch circle diameter parameters, and eccentricity between the wheel hub bolt hole pitch circle center and the center hole center.

[0008] Step 2: The wheel hub information retrieval platform determines a corresponding permission level based on the hardware number of the user terminal device, and determines a verification strategy after the wheel hub information is retrieved based on the permission level. The permission level does not restrict the method of retrieving the wheel hub information.

[0009] Step 3: Obtain the wheel hub appearance image through the image acquisition device and match it with the wheel hub appearance image features in the database.

[0010] Step 4. When the number of matching hits is less than the first preset value and greater than the second preset value, the corresponding wheel parameters and the corresponding vehicle model are fed back to the user terminal device, and verification is performed directly. When the number of matching hits is less than the second preset value, the data in the wheel information database is not fed back, and some parameters of the wheel parameters are determined by the internal and external parameters of the image acquisition module of the user terminal device, and then the corresponding remaining wheel parameters are determined based on the data of the partial parameters. After all the wheel parameters are determined, verification is performed according to the verification strategy corresponding to the user's authority level.

[0011] Furthermore, the lower the authority level, the more verification steps corresponding to the verification strategy executed.

[0012] Furthermore, the verification strategy includes:

[0013] Strategy 1: After searching a database for multiple wheels with a similarity greater than a preset threshold based on wheel appearance, the user is asked to enter a vehicle model or vehicle identification code before or after the retrieved wheel information is fed back. The wheel information retrieval platform compares the received vehicle model or vehicle identification code with the vehicle model data corresponding to the retrieved wheel information, and passes verification if the comparison is successful;

[0014] Strategy 2: determine some parameters of the wheel hub parameters through the internal and external parameters of the image acquisition module of the user terminal device, compare them with the corresponding wheel hub data in the database, and pass the verification after the comparison is successful.

[0015] Furthermore, after completing the verification, the wheel hub information retrieval platform feeds back a verification passed identifier to the user terminal device, and the user terminal device determines that the wheel hub is successfully matched based on the identifier.

[0016] Furthermore, the determining of some parameters of the hub parameters through the internal and external parameters of the image acquisition module of the user terminal device, and then determining the corresponding remaining hub parameters based on the data of the partial parameters further includes: determining the partial parameters including the bolt hole, center hole and bolt hole pitch circle diameter parameters through the internal and external parameters of the image acquisition module of the user terminal device, and then querying the corresponding hub bolt hole pitch circle center and center hole center eccentricity data in the hub information database based on the determined partial parameters.

[0020] a matching unit, which acquires an appearance image of the wheel hub through an image acquisition device and matches the appearance image features of the wheel hub in a database;

[0021] The verification unit feeds back the matched corresponding wheel parameters and the corresponding vehicle model to the user terminal device and directly performs verification when the number of matching hits is less than the first preset value and greater than the second preset value. When the number of matching hits is less than the second preset value, the data in the wheel information database is not fed back, and some parameters of the wheel parameters are determined by the internal and external parameters of the image acquisition module of the user terminal device, and then the corresponding remaining wheel parameters are determined based on the data of the partial parameters. After all the wheel parameters are determined, verification is performed according to the verification strategy corresponding to the user's authority level.

[0022] Furthermore, the lower the authority level, the more verification steps corresponding to the verification strategy executed.

[0023] Furthermore, the verification strategy includes:

[0024] Strategy 1: After searching a database for multiple wheels with a similarity greater than a preset threshold based on wheel appearance, the user is asked to enter a vehicle model or vehicle identification code before or after the retrieved wheel information is fed back. The wheel information retrieval platform compares the received vehicle model or vehicle identification code with the vehicle model data corresponding to the retrieved wheel information, and passes verification if the comparison is successful;

[0025] Strategy 2: determine some parameters of the wheel hub parameters through the internal and external parameters of the image acquisition module of the user terminal device and compare them with the corresponding wheel hub data in the database, and pass the verification after the comparison is successful.

[0026] Furthermore, after completing the verification, the wheel hub information retrieval platform feeds back a verification passed identifier to the user terminal device, and the user terminal device determines that the wheel hub is successfully matched based on the identifier.

[0027] Furthermore, the determining of some parameters of the hub parameters through the internal and external parameters of the image acquisition module of the user terminal device, and then determining the corresponding remaining hub parameters based on the data of the partial parameters further includes: determining the partial parameters including the bolt hole, center hole and bolt hole pitch circle diameter parameters through the internal and external parameters of the image acquisition module of the user terminal device, and then querying the corresponding hub bolt hole pitch circle center and center hole center eccentricity data in the hub information database based on the determined partial parameters.

[0028] Compared with the prior art, the present invention has the following beneficial effects: the present invention discloses a method for storing and retrieving wheel hub information, the method comprising the following steps: constructing a database for storing wheel hub information, the database comprising wheel hub appearance image features and wheel hub parameters corresponding to vehicle models, constructing a wheel hub information retrieval platform, a user terminal device sending a request to access the database for storing wheel hub information through the platform, wherein the wheel hub parameters include bolt hole, center hole and bolt hole pitch circle diameter parameters and eccentricity of wheel hub bolt hole pitch circle center and center hole center; the wheel hub information retrieval platform determines the corresponding authority level according to the hardware number of the user terminal device, and determines the verification strategy after the retrieval of the wheel hub information according to the authority level, wherein The permission level does not restrict the method of retrieving wheel hub information; an image of the wheel hub's appearance is acquired through an image acquisition device and matched with the wheel hub appearance image features in a database; when the number of matching hits is less than a first preset value but greater than a second preset value, the corresponding wheel hub parameters and the corresponding vehicle model are fed back to the user terminal device and verification is performed directly; when the number of matching hits is less than the second preset value, the data in the wheel hub information database is not fed back, and some of the wheel hub parameters are determined through the internal and external parameters of the image acquisition module of the user terminal device, and then the corresponding remaining wheel hub parameters are determined based on the data of the partial parameters; after all the wheel hub parameters are determined, verification is performed according to the verification strategy corresponding to the user's permission level.

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention can be further understood from the following description in conjunction with the accompanying drawings. The components in the figures are not necessarily drawn to scale, but rather emphasis is placed on illustrating the principles of the embodiments. In the figures, the same reference numerals designate corresponding parts in different views.

[0030] Figure 1 It is a flow chart of a method for storing and retrieving wheel hub information of the present invention. DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0032] A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the subsequent description, suffixes such as "module," "component," or "unit" used to denote components are used solely to facilitate description of the present invention and do not inherently have specific meanings. Therefore, "module" and "component" may be used interchangeably.

[0033] Mobile terminals can be implemented in various forms. For example, the terminals described in the present invention may include mobile terminals such as mobile phones, smart phones, laptop computers, digital broadcast receivers, PDAs (personal digital assistants), PADs (tablet computers), PMPs (portable multimedia players), navigation devices, and the like, as well as fixed terminals such as digital TVs and desktop computers. Below, it is assumed that the terminal is a mobile terminal. However, those skilled in the art will appreciate that, in addition to components specifically designed for mobile use, the configurations according to the embodiments of the present invention can also be applied to fixed-type terminals.

[0034] In the present invention, the user uses a terminal device, such as a mobile phone or other device with an image acquisition function as a client to input query information, and the query information includes collected image information, input vehicle information, and the like.

[0035] The hub information retrieval platform includes a port connected to the user terminal device, through which the data information submitted by the user is received and the retrieval results are fed back to the user's terminal device.

[0036] The wheel hub information retrieval platform includes multiple database servers connected to it, including at least a first database for storing wheel hub information and a second database for storing vehicle information. Because the database authority requirement for vehicle information is greater than that for wheel hub information, the databases are differentiated and stored in two databases to reduce the number and frequency of accesses to the database storing vehicle information. This is also a main concept and invention point of the present invention.

[0037] like Figure 1 A method for storing and retrieving wheel hub information is shown, the method comprising the following steps:

[0038] Step 1: Build a database to store wheel hub information, the database including wheel hub appearance image features and wheel hub parameters corresponding to vehicle models, and build a wheel hub information retrieval platform. User terminal devices send a request to access the database storing wheel hub information through the platform and access the database. The wheel hub parameters include bolt hole, center hole and bolt hole pitch circle diameter parameters, and eccentricity between the wheel hub bolt hole pitch circle center and the center hole center.

[0039] Step 2: The wheel hub information retrieval platform determines a corresponding permission level based on the hardware number of the user terminal device, and determines a verification strategy after the wheel hub information is retrieved based on the permission level. The permission level does not restrict the method of retrieving the wheel hub information.

[0040] Step 3, obtaining an appearance image of the wheel hub through an image acquisition device and matching it with the wheel hub appearance image features in a database;

[0041] Step 4. When the number of matching hits is less than the first preset value and greater than the second preset value, the corresponding wheel parameters and the corresponding vehicle model are fed back to the user terminal device, and verification is performed directly. When the number of matching hits is less than the second preset value, the data in the wheel information database is not fed back, and some parameters of the wheel parameters are determined by the internal and external parameters of the image acquisition module of the user terminal device, and then the corresponding remaining wheel parameters are determined based on the data of the partial parameters. After all the wheel parameters are determined, verification is performed according to the verification strategy corresponding to the user's authority level.

[0042] Furthermore, the lower the authority level, the more verification steps corresponding to the verification strategy executed.

[0043] Furthermore, the verification strategy includes:

[0044] Strategy 1: After searching a first database for multiple wheels with a similarity greater than a preset threshold based on wheel appearance, the user is asked to enter a vehicle model or vehicle identification code before or after the retrieved wheel information is fed back. The wheel information retrieval platform compares the received vehicle model or vehicle identification code with the vehicle model data corresponding to the retrieved wheel information, and passes verification if the comparison is successful.

[0045] In this strategy, the second database includes the vehicle model or vehicle identification code, such as the frame number, etc., which are pre-stored in the second database corresponding to the wheel hub information retrieval platform. The wheel hub information retrieval platform searches for the vehicle parameter information in the second database connected to the wheel hub information retrieval platform based on the information (vehicle model or vehicle identification code) received from the user input through the client. The vehicle parameter information at least includes the factory-provided wheel hub information. Therefore, in strategy one, the user searches through appearance, such as image feature extraction. The user collects the appearance picture of the wheel hub through the client and uploads the collected picture to the wheel hub retrieval platform for feature comparison of the picture. A similarity sequence is determined based on the similarity of the comparison, and then the vehicle information input by the user for the second time is used to determine whether the identified appearance image is a wheel hub produced by the vehicle factory.

[0046] Furthermore, the above-mentioned first database is used to record all retrievable wheel hub information, such as the appearance of the wheel hub, the specific wheel hub name, model and corresponding parameters, etc. The above-mentioned second database records the vehicle model, vehicle identification code (such as frame number, engine number, etc.) and factory wheel hub information.

[0047] Strategy 2: determine some parameters of the wheel hub parameters through the internal and external parameters of the image acquisition module of the user terminal device, compare them with the corresponding wheel hub data in the database, and then pass the verification after the comparison is successful.

[0048] In strategy 2, after all wheel hub parameters are obtained based on the collected specific parameters, this strategy is used to verify the parameters other than the specific parameters to determine whether the retrieved parameter information is correct.

[0049] For example, the above article defines that the hub parameters include bolt hole, center hole and bolt hole pitch circle diameter parameters, as well as the eccentricity of the hub bolt hole pitch circle center and the center hole center. If the specific part of the parameters is the center hole and bolt hole pitch circle diameter parameters, after determining all the hub information through the center hole and bolt hole pitch circle diameter parameters, based on the corresponding other information such as bolt hole parameters as verification indicators, the user collects the hub bolt hole parameters through the terminal device. Because the actual size of the collected image can be determined based on the internal and external parameters of the camera device, the collected bolt hole parameters submitted by the user are verified to be the same as the retrieved bolt hole parameters, and the verification work is completed. Furthermore, after the verification is completed, the hub information retrieval platform will feedback the verification pass mark to the user terminal device, and the user terminal device will determine the successful matching of the hub based on the mark.

[0050] Furthermore, the determining of some parameters of the hub parameters through the internal and external parameters of the image acquisition module of the user terminal device, and then determining the corresponding remaining hub parameters based on the data of the partial parameters further includes: determining the partial parameters including the bolt hole, center hole and bolt hole pitch circle diameter parameters through the internal and external parameters of the image acquisition module of the user terminal device, and then querying the corresponding hub bolt hole pitch circle center and center hole center eccentricity data in the hub information database based on the determined partial parameters.

[0051] After performing the test, the present invention further evaluates the verification results, and the evaluation function used is:

[0052]

[0053] Among them, μ1 represents the verification step evaluation corresponding to the lowest authority level, is the variance of the verification step evaluation corresponding to the highest authority level, α is the verification model parameter of the strategy 1, and β is the verification model parameter of the strategy 2.

[0054] In this embodiment, α and β can be the success rates of the verification models for Strategy 1 and Strategy 2, respectively, corresponding to the user's permissions. For example, samples that pass verification using Strategy 1 or 2 are then manually verified by a manager to determine the success rate. The provided evaluation results are used by the manager to assess the effectiveness of the entire retrieval system.

[0055] The present invention also discloses a hub information storage and retrieval system, which includes the following units:

[0057] an authority determination unit, determining a corresponding authority level according to the hardware number of the user terminal device, and determining a verification strategy after retrieving the wheel hub information according to the authority level, wherein the authority level does not restrict the method of retrieving the wheel hub information;

[0058] A matching unit, which acquires an appearance image of the wheel hub through an image acquisition device and matches it with the wheel hub appearance image features in a database;

[0059] The verification unit feeds back the matched corresponding wheel parameters and the corresponding vehicle model to the user terminal device and directly performs verification when the number of matching hits is less than the first preset value and greater than the second preset value. When the number of matching hits is less than the second preset value, the data in the wheel information database is not fed back, and some parameters of the wheel parameters are determined by the internal and external parameters of the image acquisition device of the user terminal device, and then the corresponding remaining wheel parameters are determined based on the data of the partial parameters. After all the wheel parameters are determined, verification is performed according to the verification strategy corresponding to the user's authority level.

[0060] Furthermore, the lower the authority level, the more verification steps corresponding to the verification strategy executed.

[0061] Furthermore, the verification strategy includes:

[0062] Strategy 1: After searching a database for multiple wheels with a similarity greater than a preset threshold based on wheel appearance, the user is asked to enter a vehicle model or vehicle identification code before or after the retrieved wheel information is fed back. The wheel information retrieval platform compares the received vehicle model or vehicle identification code with the vehicle model data corresponding to the retrieved wheel information, and passes verification if the comparison is successful;

[0063] Strategy 2: determine some parameters of the wheel hub parameters through the internal and external parameters of the image acquisition module of the user terminal device, compare them with the corresponding wheel hub data in the database, and pass the verification after the comparison is successful.
