Description

Technical Field

[0001] This application relates to the field of vehicle inspection technology, and more specifically, to a tire inspection device, system, method, vehicle, and storage medium. Background Technology

[0002] With industrial development and advancements in manufacturing technology, the cost of vehicle production has been effectively reduced, enabling more people to own a car or motorcycle. While users are increasingly aware of vehicle safety, many may notice the importance of tire pressure but often overlook the importance of tread depth and the presence of foreign objects on the surface. Specifically, the main tread grooves of the tire must be at least 1.6 mm deep and cover 3 / 4 of the tread surface. Wear checks must be performed at multiple points along the tire's outer edge and width.

[0003] There are currently three main methods for tire tread inspection. First, using a tread depth gauge: This method accurately measures the outer, middle, and inner sides of the tire tread. During measurement, the tread wear pointer of the gauge is inserted into the main tread pattern of the tire. Second, using a 20-pence coin: This works because the outer edge of a 20-pence coin is perfectly sized to measure a depth of 1.6 millimeters. The driver simply inserts the coin into the partially worn tire and checks if the outer edge disappears. If it doesn't, the remaining tread depth is still sufficient. If the outer edge of the coin protrudes beyond the tire, the partially worn tire is invalid and needs immediate replacement. Third, have a professional mechanic inspect it.

[0004] In summary, the current tire tread detection methods are neither convenient nor intelligent. Summary of the Invention

[0005] A first aspect of this application provides a tire inspection device. The tire inspection device includes: An imaging unit is mounted on the vehicle body in a manner facing the tires of the vehicle and is configured to capture three-dimensional images of the tires. A processing unit, connected to the imaging unit, is configured to determine the tire's detection result based on a three-dimensional image of the tire. The tire's detection result includes at least one of the following information: the tire's current tread depth, the tire's remaining safe tread depth margin, whether there are foreign objects on the tire's surface, the type of foreign objects on the tire's surface, the distribution of foreign objects on the tire's surface, the tire's warning information, tire maintenance and replacement recommendations, and the tire's regular inspection plan; and A communication unit is configured to enable the processing unit to communicate with a server, so that the processing unit sends a three-dimensional image of the tire and the detection result of the tire to the server.

[0006] The tire inspection device of the first aspect of this application acquires a three-dimensional image of the tire through an imaging unit, and the processing unit analyzes the three-dimensional image of the tire to determine multiple inspection results, such as tread depth, remaining safe tread depth, and the presence and distribution of foreign objects on the tire surface. This not only automates tire condition inspection, improving accuracy and efficiency, but also transmits the inspection results to a server via a communication unit, facilitating centralized data management, remote monitoring, and maintenance. This enhances the intelligence level of vehicle safety management and improves the scalability and management efficiency of the tire inspection device.

Based on the three-dimensional image of the tire, the inspection result of the tire is determined. The inspection result includes at least one of the following information: the current tread depth of the tire, the remaining safe tread depth margin of the tire, whether there are foreign objects on the surface of the tire, the type of foreign objects on the surface of the tire, the distribution of foreign objects on the surface of the tire, the tire's warning information, the tire's maintenance and replacement recommendations, and the tire's regular inspection plan; and The system sends a 3D image of the tire and the detection results of the tire to the server.

[0012] The tire inspection method of the fourth aspect of this application acquires three-dimensional images of the tire when the vehicle is stationary or the tire is rotating, and analyzes them to generate detailed inspection results. This method achieves automated and comprehensive tire inspection, accurately assesses tread depth and surface condition, promptly identifies potential problems, and ensures tire safety and service life.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other. It can be directly connected, or indirectly connected through an intermediate medium. It can be the connection inside two elements or the interaction relationship between two elements.

[0027] For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0028] Refer Figure 1 , a tire detection system 200 according to an embodiment of the present application is used to detect the tires 120 of a vehicle 100 to issue a warning to the user's mobile terminal (not shown in the figure) or the central control system of the vehicle 100 (not shown in the figure) when the tires 120 are abnormal.

[0029] Specifically, the tire detection system 200 includes a tire detection device 210 and a server 220 that communicates with the tire detection device 210. The tire detection device 210 includes an imaging unit 211 and a control unit 212. The control unit 212 is electrically connected to the imaging unit 211 and is communicatively connected to the server 220.

[0030] The imaging unit 211 is mounted on the vehicle body 110 of the vehicle 100 so as to face the tire 120 of the vehicle 100. The imaging unit 211 is configured to capture a three-dimensional image of the tire 120. The control unit 212 is used to detect the tread wear condition, the foreign object distribution condition, the remaining tread depth margin, etc. of the tire 120 based on the image captured by the imaging unit 211, and when an abnormality of the tire 120 is detected, a warning signal is sent to the server 220.

[0031] Specifically, the imaging unit 211 can be mounted at a position such as a fender of the vehicle 100 and face the tire 120.

[0032] In some embodiments, an imaging unit 211 is provided corresponding to each tire 120 of the vehicle 100. For example, the vehicle 100 is an automobile, and an imaging unit 211 corresponds to each of the four tires 120 of the automobile, and each imaging unit 211 is electrically connected to the control unit 212.

[0033] See Figure 2 , the tire detection device 210 further includes a housing 213. The imaging unit 211 is located inside the housing 213. The housing 213 has an opening H, and the imaging unit 211 is exposed at the opening H to face the tire 120.

[0034] In some embodiments, a shielding cover (not shown in the figure) is provided at the position of the fender of the vehicle 100. The shielding cover shields the opening H of the housing 213, and when the tire 120 needs to be detected, the shielding cover can be opened.

[0035] Thus, the imaging unit 211 is protected by the housing 213 and the shielding cover, which is beneficial to avoiding the influence of the imaging unit 211 by the external environment (such as dust, rain, etc.), and prolongs the service life of the tire detection device 210. At the same time, the design of the opening H of the housing 213 ensures that the imaging unit 211 can effectively face the tire 120 for detection, ensuring the quality of image acquisition and the accuracy of detection.

[0036] Specifically, the imaging unit 211 includes a laser 211a and an image sensor 211b. The laser 211a is configured to emit dot structured light to the tire 120 at the opening H. The image sensor 211b is configured to take pictures of the laser pattern generated on the surface of the tire 120 by the dot structured light to generate a three-dimensional image of the tire 120.

[0037] It should be noted that for the image sensor 211b for single-point laser ranging, only by knowing the pixel position of the bright point can the object distance be immediately deduced. Among them, the image sensor 211b only needs to be one-dimensional, that is, a linear image sensor 211b. Since the linear image sensor 211b can only measure the distance of one point at a time, if many positions need to be measured, such as a curve, the measurement position needs to be moved, and samples are taken and the measurement results are recorded at different positions. Such a measurement method is very laborious, especially when it is necessary to be very dense and the point distance is very small, the efficiency of multi-point sampling is relatively low.

[0038] Refer Figure 3 , different from the Figure 2 tire detection device 210 shown, Figure 3 in which the laser 211a is configured to emit line structured light towards the tire 120, and the image sensor 211b is configured to take pictures of the laser pattern generated by the line structured light on the surface of the tire 120 to generate a three-dimensional image of the tire 120.

[0039] Figure 3 In Figure 3 the right part, a lens 211c that can project the light beam into a line is installed in front of the single-point laser light source. It can project a virtual wall in space, and the place illuminated by this wall will show diffuse light traces in a straight or curved shape along the contour of the object. Refer

[0040] Refer Figure 3 the left part, the image sensor 211b is a two-dimensional area array image sensor. The laser trace is projected and imaged on the image sensor 211b through the lens 211c. At this time, a row of pixel columns is actually a group of point laser rangings, and the position of the light point can be detected and the distance and height can be measured for each row. If the width of this image sensor 211b has 1280 columns, it is equivalent to the effect of 1280 point laser rangings. Therefore, when optimizing the measurement of the curve, the efficiency is increased by hundreds to thousands of times compared with the point structured light detection.

[0041] Since the imaging unit 211 can only measure one contour line at a time, if you want to restore the three-dimensional surface topography of the entire object, you must move the entire imaging unit 211 or the待测 tire 120 moves. Through the relative movement method, multiple contours are sampled to piece together the three-dimensional surface topography of the entire surface of the tire 120.

[0042] Thus, by integrating the laser 211a and the image sensor 211b in the imaging unit 211 and adopting the point structured light or line structured light technology, a three-dimensional image of the tire 120 can be accurately generated. This structured light technology improves the accuracy and reliability of image acquisition, makes the detection of tread depth and surface foreign objects more accurate, and further improves the performance of the tire detection device 210 and the credibility of the detection results.

[0043] Reference Figure 4 , in the tire detection device 210 of the tire detection system 200, the control unit 212 includes a storage unit 212a, a processing unit 212b, and a communication unit 212c.

[0044] The storage unit 212a may have a computer program executed by the processing unit 212b. The storage unit 212a may be any memory or combination of memories readable by a computer.

[0045] The processing unit 212b is connected to the storage unit 212a and the imaging unit 211. The processing unit 212b is configured to determine the detection result of the tire 120 based on the three-dimensional image of the tire 120 captured by the imaging unit 211.

[0046] The detection result of the tire 120 includes at least one of the following information: the current tread depth of the tire 120, the remaining safe tread depth margin of the tire 120, whether there is a foreign object on the surface of the tire 120, the type of the foreign object on the surface of the tire 120, the distribution of the foreign object on the surface of the tire 120, the warning information of the tire 120, the maintenance and replacement suggestions for the tire 120, and the regular detection plan for the tire 120.

[0047] The regular detection plan for the tire 120 may be to remind the user to perform regular detection, or to perform detection according to a time gradient based on the detection result, etc. In addition, the processing unit 212b may also be associated with other applications of the user terminal for reminder or recommendation, etc.

[0048] The communication unit 212c is configured to enable the processing unit 212b to communicate with the server 220, so as to implement the processing unit 212b to send the three-dimensional image of the tire 120 and the detection result of the tire 120 to the server 220. The communication unit 212c is configured to be connectable to a network such as a Bluetooth network or a wireless local area network (Wireless Local Area Networks, WLAN) (such as a wireless fidelity (Wireless Fidelity, Wi-Fi) network).

[0049] In the tire detection system 200 according to the embodiment of the present application, the three-dimensional image of the tire 120 is obtained by the imaging unit 211, and the three-dimensional image of the tire 120 is analyzed by the processing unit 212b to determine multiple detection results such as the tread depth, the remaining safe tread depth, the foreign object on the surface of the tire 120, and its distribution.

[0050] Thus, not only can the condition of the tire 120 be automatically detected, improving the accuracy and efficiency of detection, but also the detection results are transmitted to the server 220 through the communication unit 212c, realizing centralized management, remote monitoring and maintenance of data, enhancing the intelligent level of vehicle 100 safety management, and improving the scalability and management efficiency of the tire detection system 200.

[0051] The vehicle 100 according to the embodiment of the present application, by integrating the tire detection device 210, has the ability to monitor the tread condition in real time, improves the intelligent level of the vehicle, enhances driving safety, and at the same time provides convenient tire maintenance information for the vehicle owner, reducing potential safety hazards caused by tread wear.

[0052] Please continue to refer to Figure 4 The tire detection device 210 further includes a driving mechanism 214. The driving mechanism 214 is connected to the imaging unit 211 and the processing unit 212b.

[0053] The driving mechanism 214 is configured to drive the imaging unit 211 to move relative to the tire 120. The processing unit 212b is further configured to, when the vehicle 100 is stationary, cause the driving mechanism 214 to drive the imaging unit 211 to move relative to the tire 120 and cause the imaging unit 211 to capture a three-dimensional image of the tire 120. Thus, a comprehensive three-dimensional image of the tire 120 can still be obtained when the vehicle 100 is stationary, ensuring accurate detection of the tread condition in different driving states. In addition, the presence of the driving mechanism 214 enables the device to cover multiple detection points of the tire 120, further improving the comprehensiveness and accuracy of detection.

[0054] The tire detection device 210 further includes a user interface 215. The user interface 215 is connected to the processing unit 212b and is configured to display the three-dimensional image of the tire 120 and the detection results of the tire 120.

[0055] Thus, integrating the user interface 215 in the tire detection device 210 enables the detection results and the three-dimensional image of the tire 120 to be intuitively displayed to the user, improving the user's understanding of the condition of the tire 120 and decision-making ability. By displaying the detection information in real time, the user can take repair or replacement measures in a timely manner, enhancing the safety of the vehicle 100 and the user experience.

[0056] In some embodiments, the user interface 215 may be, but is not limited to: the in-vehicle screen of the vehicle 100, the user's mobile terminal (such as a mobile phone), a driving recorder, etc.

[0057] Refer to Figure 5The tire inspection method of this application includes the following steps S1 to S3. Depending on different needs, the order of some steps or sub-steps of the tire inspection method can be changed, and some steps or sub-steps can be omitted or combined.

[0058] In addition, you can refer to Figures 1 to 4 understand Figure 5 The tire inspection method shown is not limited to the implementation structure of this tire inspection method. Figures 1 to 4 The tire inspection device (tire inspection system or vehicle) shown.

[0059] Step S1: Obtain a 3D image of the tire.

[0060] In some embodiments, the references Figure 1 Step S1 includes: keeping the imaging unit 211 mounted on the vehicle 100 stationary, driving the tire 120 of the vehicle 100 to rotate, thereby enabling the imaging unit 211 to acquire a three-dimensional image of the tire 120.

[0061] This fixed-point scanning method of the imaging unit 211 eliminates the need for an additional drive mechanism to move the imaging unit 211, but requires the vehicle 100 to be started to rotate the tire 120 in order to obtain a more complete surface appearance and tread depth of the tire 120.

[0062] In some embodiments, the references Figure 1 Step S1 includes: when the vehicle 100 is stationary, driving the imaging unit 211 mounted on the vehicle 100 to move relative to the tire 120 of the vehicle 100, thereby enabling the imaging unit 211 to acquire a three-dimensional image of the tire 120.

[0063] This type of imaging unit 211 can move and scan without moving the vehicle 100 to obtain three-quarters or even one-half of the tire 120 surface condition as sampling data, which can also represent the tire tread depth. However, it requires an additional drive mechanism to move the imaging unit 211.

[0064] Step S2: Determine the tire inspection results.

[0065] Specifically, step S2 includes: determining the inspection result of tire 120 based on the three-dimensional image of tire 120. The inspection result of tire 120 includes at least one of the following information: the current tread depth of tire 120, the remaining safe tread depth margin of tire 120, whether there are foreign objects on the surface of tire 120, the type of foreign objects on the surface of tire 120, the distribution of foreign objects on the surface of tire 120, warning information of tire 120, maintenance and replacement recommendations for tire 120, and the regular inspection plan for tire 120.

[0066] Step S3: Send the 3D image of the tire and the tire detection results.

[0067] Specifically, refer to Figure 1 Step S3 includes sending a three-dimensional image of the tire 120 and the detection results of the tire 120 to the server 220.

[0068] In some embodiments, the references Figure 4 Step S3 also includes displaying a three-dimensional image of the tire 120 and the detection results of the tire 120 on the user interface 215.

[0069] The tire inspection method of this application acquires a three-dimensional image of the tire when the vehicle is stationary or the tire is rotating, and analyzes and generates detailed inspection results. This method achieves automated and comprehensive tire inspection, accurately assesses tread depth and surface condition, promptly identifies potential problems, and ensures tire safety and lifespan. The following example illustrates the linkage mechanism between the user's mobile terminal (using a mobile phone as an example) and the vehicle's infotainment system.

[0070] Specifically, the user's mobile terminal has one or more of the following functions, but not limited to: (1) Real-time updates of test results: Users can view the latest tire test results in real time on the mobile application, including tread depth, foreign object information and other test content.

[0071] (2) Push safety reminders: If the detection results involve safety hazards (such as insufficient tire tread depth, foreign objects that may cause driving risks, etc.) in the user's mobile phone application, the system will automatically generate a push notification to remind the user to check the relevant information as soon as possible.

[0072] (3) Repair suggestions and operation appointment: The user's mobile application will provide specific repair or replacement suggestions based on the test results, and provide a one-click appointment function. Users can choose the nearest repair shop or 4S store for processing.

[0073] (4) Regular inspection reminders: The tire inspection system will generate a personalized inspection plan based on the tire condition and mileage, and remind users to check on time in the form of a calendar or regular notification.

[0074] The in-vehicle infotainment system has one or more of the following functions, but is not limited to: (1) Mandatory safety confirmation before driving: If the user does not view or confirm the tire inspection information in the mobile application, the vehicle will automatically pop up a safety prompt window when the vehicle is started, displaying the key inspection information of the current tires (such as insufficient tread depth, presence of foreign objects, maintenance suggestions, etc.). The user must manually click "Confirm" before the vehicle can be unlocked or started. If the inspection results show that there is a serious safety hazard (such as tread depth below the critical value or foreign objects seriously affecting driving), the vehicle will emit a high-intensity alarm sound and provide quick options of "View the nearest repair shop" or "Contact customer service for processing".

[0075] (2) Real-time monitoring and alerts: During driving, the vehicle system continuously monitors the tire status (through the vehicle's tire detection system). If changes in tire pressure, tread depth, or foreign objects exceed the safe range, a pop-up alert will be displayed immediately, and relevant information will be announced via voice. If the user chooses to ignore the alert, the tire detection system will record the status and remind the user again the next time the vehicle is started.

[0076] The vehicle's infotainment system and mobile devices can synchronize in, but are not limited to, the following ways: all alerts from the vehicle's infotainment system will be simultaneously sent to the mobile application, allowing users to view and manage them when not driving. The mobile application can also remotely view the vehicle's current tire status, enabling users to monitor tire information at any time.

[0077] Specific use cases are illustrated below.

[0078] Scenario 1: Safety check before driving.

[0079] As the user prepares to leave, they open the mobile application and find a notification: "The tread depth of the front right tire is approaching the safety threshold. Please replace it as soon as possible." After viewing the notification, the user can use the application to schedule an appointment at the nearest repair shop for processing.

[0080] If the user does not view this notification, the vehicle will display a pop-up message when starting the vehicle: "The tread depth of the front right tire is insufficient. It is recommended to replace it before driving." The user must manually confirm before starting the vehicle.

[0081] Scenario 2: Safety tips while driving.

[0082] If a suspected metallic foreign object is detected on the surface of the left rear tire while the vehicle is traveling at high speed, the system will immediately display a pop-up warning and suggest that the user check the tire or stop at the nearest service area to handle the issue. Simultaneously, the warning will also be sent to the user's mobile application.

[0083] Scenario 3: Regular testing reminders.

[0084] Based on tire usage and inspection schedules, the user's mobile application sends a "Monthly Tire Inspection Reminder" at the beginning of each month to guide the user to check their tires on time. If the user ignores this reminder, the vehicle's system will prompt "Please complete the tire inspection as soon as possible" when the accumulated mileage exceeds the inspection cycle.

[0085] To further enhance safety and convenience, the tire inspection system can also include the following functions: (1) Remote diagnosis and technical support: When an abnormal situation is detected, users can connect to the customer service center through a mobile application or vehicle system, and professional technicians can remotely diagnose the problem and provide solutions.

[0086] (2) Predictive maintenance: By collecting tire usage data (such as tire pressure changes, mileage, driving environment, etc.), the tire detection system can predict the remaining life of the tire and remind the user to replace it in advance.

[0087] (3) Personalized inspection service: Users can set inspection preferences in the mobile application (such as only indicating the tire tread depth, ignoring minor foreign objects, etc.) to achieve personalized display of inspection content.

[0088] This application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program, which, when executed by a processor, implements the tire detection method described above.

[0089] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
