[0028] See also Figure 1 and Figure 2As shown in the figure, the embodiment of the present invention provides an information prompt method based on face recognition, which is applied to the management server 10 of the vehicle system. If the management server 10 detects that the vehicle is started, the preset face recognition module 20 is called; the face recognition module 20 is controlled to perform face recognition on the user to obtain corresponding face recognition information, wherein the face recognition information at least includes user mark information; if the user mark information is located in a preset information database, the user feature information associated with the user mark information is obtained from the preset information database; the management server 10 parses the obtained user feature information and calls the function module 30 corresponding to the user feature information to perform corresponding information prompts. This method can not only realize the rapid identification of specific users and generate specific information prompts required by users, but also actively respond to user needs and improve the user experience.

[0029] like Figure 1 As shown, in one embodiment, the information prompting method based on face recognition is applied to a management server in a vehicle system, and the method includes steps S110 to S140.

[0030] Step S110: If the vehicle is detected to be started, a preset face recognition module is called.

[0031] In this embodiment, the vehicle system is an important part of the vehicle, which integrates multiple functions such as navigation, entertainment, communication, and vehicle status monitoring. The performance and function of the vehicle system determine the intelligence level of the vehicle. When the management server of the vehicle system detects that the vehicle is started by the user, the pre-set face recognition module can be directly called.

[0032] Among them, the face recognition module needs to match the vehicle computer system. The basic principle of the face recognition module is to extract and compare the features of the face image to obtain relevant character information. This process usually includes the following steps: 1. Obtain the user's facial image through a camera or other device; 2. Use a specific recognition algorithm to calculate the position of the face in the image; 3. Extract key feature points or feature vectors from the detected user's facial image. These feature points may include the outline of the face, the position of the eyebrows, the distance between the eyes, etc. The feature vector is the result of the numerical representation of these feature points; 4. Compare the extracted features with the pre-stored facial features. The comparison method may include calculating the similarity of the feature points or matching the feature vectors, etc. The comparison result will produce a similarity or matching score; 5. Determine whether the recognition is successful based on the comparison result and output the recognition result.

[0033] The face recognition model can be integrated based on the algorithm in the face recognition algorithm library, or it may be based on the model in the open source computer vision library, such as OpenCV, SeetaFace6 and other open source libraries. When selecting a specific face recognition model, it is necessary to consider multiple factors, such as recognition accuracy, real-time performance, security, compatibility and development cost; at the same time, it is also necessary to match it according to the specific requirements of the car manufacturer to ensure that the selected model can meet the actual needs of the car manufacturer.

[0034] Step S120, controlling the face recognition module to perform face recognition on the user to obtain corresponding face recognition information, wherein the face recognition information at least includes user identification information.

[0035] In this embodiment, after calling the face recognition module, the management server can perform face recognition on the user, thereby obtaining corresponding face recognition information. Through the user identification information contained in the face recognition information, it can be determined whether the user has the right to use and call the feature information associated with the user. Among them, the user identification information can be the user's account information, or it can be information that can uniquely identify the user, such as the phone number used by the user when registering, which is not limited in this embodiment.

[0036] Step S130: If the user identification information is located in a preset information database, user characteristic information associated with the user identification information is obtained from the preset information database.

[0037] In this embodiment, the management server can determine whether the user identification information is located in a preset information database. The preset information database includes the user's characteristic information. For example, usually one user corresponds to one user account information. The user account information can be used as the user's identification information and can be associated with other characteristic information of the user, such as the user's ID number, the user's operating habits, the time and path of the user's use of the vehicle, the driving conditions of the vehicle, etc. In particular, the user's characteristic information can be the owner, ID card, phone number provided when purchasing the vehicle, or the name, ID card, phone number, face and other information provided when registering the vehicle control App. At the same time, it is also necessary to confirm that the above user data is publicly available after being stored in the information database.

[0038] Step S140, parsing the acquired user characteristic information and calling a function module corresponding to the user characteristic information to perform corresponding information prompting.

[0039] In this embodiment, the management server can also parse the acquired user characteristic information, where different characteristic information may correspond to different functional modules, and different functional modules are used to implement prompts for user information. For example, the user's characteristic information may be the user's birthday information, and through the birthday information, a screen display module can be called according to a pre-set rule to generate and display specific blessing information, which can improve the user's experience.

[0040] In one embodiment, the user characteristic information includes an ID number, and the step S140 includes the following steps: parsing and identifying the ID number to obtain the user's birthday information and gender information; sending the identified birthday information and gender information to a preset data processing module to obtain target prompt information; sending the target prompt information to the information prompt module of the vehicle system for information prompting.

[0041] If the user characteristic information includes an ID number, since the 7th to 14th digits of the ID number represent the date of birth, the 17th digit of the ID number can be used to distinguish the gender, if it is an odd number, it is male, and if it is an even number, it is female. When the ID number is parsed and identified to obtain the user's birthday information and gender information; after the user's birthday information and gender information are sent to a preset data processing module, the data processing module can call the target prompt information that matches the user's birthday information and gender information according to the preset rule information. If it is detected that it is the user's birthday, birthday-related blessing information is called, and the blessing information related to the user's gender is adjusted according to the user's gender.

[0042] In a further embodiment, the target prompt information includes birthday greeting information, and the step of sending the identified birthday information and gender information to a preset data processing module to obtain the target prompt information includes:

[0043] The identified birthday information is sent to a preset data processing module to determine whether the current date matches the user's birthday information; if so, the preset data processing module is controlled to generate corresponding birthday blessing information according to the gender information.

[0044] Among them, when the target prompt information is birthday blessing information, the data processing module is required to determine in advance whether the user's birthday information matches the current date. If it matches, the preset data processing module is controlled to generate corresponding birthday blessing information according to the gender information. For example, if the user is a female, the generated birthday blessing information is a blessing that meets the habits and needs of women. If the user is a male, a blessing related to the habits and needs of men is generated. The data processing module can perform statistical analysis, data mining, machine learning, etc. on the data to extract useful information.

[0045] In a further embodiment, the method further comprises:

[0046] If it is detected that the current time does not match the user's birthday information, the relevant information for the information prompt will be deleted and the vehicle system will be restored to the default state recognized by the user.

[0047] In one embodiment, if the management server detects that the current time does not match the user's birthday information, the management server can delete the relevant information for information prompts, such as birthday greetings, etc., thereby restoring the vehicle system to the default state previously recognized by the user, thereby not affecting the user's normal use.

[0048] In a further embodiment, the information prompt module includes an audio processing module and a screen display module, the target prompt information includes audio information and image information, and the step of sending the target prompt information to the information prompt module of the vehicle system for information prompting includes:

[0049] The image information is sent to a screen display module, and the audio information is sent to an audio processing module; the image information and the audio information are controlled to be displayed and played synchronously for information prompting.

[0050] Among them, sending the image information to the screen display module and sending the audio information to the audio processing module is a key link in the multimedia information processing process. It ensures the diversified transmission of information. Therefore, it is necessary to accurately control the synchronous display and playback of image information and audio information to provide efficient and intuitive information prompts.

[0051] Specifically, the image information (such as static images, dynamic images or video streams) is processed and sent to the screen display module through a specific communication protocol and interface; the screen display module may be an LCD display, LED display, OLED display or other types of display devices. After the audio information (such as voice prompts, background music, sound effects, etc.) is processed, it is sent to the audio processing module through the audio processing interface; the audio processing module may include components such as an audio decoder, an audio amplifier, and a speaker. When sending image information and audio information, ensure the synchronization and continuity of the image information and audio information to ensure sound quality and playback effect.

[0052] In one embodiment, before the step of sending the image information to the screen display module and sending the audio information to the audio processing module, it also includes: sending the target prompt information to a preset virtual module to generate corresponding virtual dynamic image information.

[0053] After receiving the target prompt information, the virtual module will convert the target prompt information into virtual dynamic image information according to preset rules and algorithms. The virtual dynamic image information can be two-dimensional (such as graphics or animations on the screen), and of course, in further embodiments, it can also be three-dimensional (such as objects in virtual reality or augmented reality environments); in addition, the process of generating virtual dynamic image information may involve complex technologies such as graphics rendering, animation production, and physical simulation.

[0054] Furthermore, based on the user's feedback and interactive behavior, the generation method and display effect of the virtual dynamic image information can also be adjusted. For example, if the user can adjust the color, shape, size or animation effect involved in the virtual dynamic image information.

[0055] In one embodiment, the step S104 further includes the following steps:

[0056] The current geographical location is obtained based on GPS, and relevant recommended information is automatically screened and generated according to the current geographical location and user characteristic information; the generated recommended information and user characteristic information are sent to the corresponding function module for information prompting.

[0057] The management server obtains the current geographic location information through the built-in GPS module or network positioning services (such as A-GPS, Wi-Fi positioning, base station positioning, etc.). Based on the user's current geographic location and feature information, the system uses algorithms (such as collaborative filtering, content recommendation, deep learning, etc.) to filter and generate relevant recommendation information. Recommended information can include nearby restaurants, stores, attractions, activities, coupons, etc., and will also consider time factors (such as whether the user is near meal time), user preferences (such as whether the user likes a certain type of food or activity), and other possible contextual information (such as weather, traffic conditions, etc.) to optimize the recommendation results.

[0058] In summary, the above-mentioned information prompt method based on face recognition is applied to the management server. This method can not only realize the online and automated development of APP iteration, improve the efficiency and quality of APP iteration, but also facilitate timely editing and adjustment of APP iteration information, actively respond to user needs, improve user experience, and effectively reduce the overall development cost.

[0059] The embodiment of the present invention also provides an information prompting device based on face recognition, which can be configured in a management server of a vehicle system, and is used to execute any embodiment of the information prompting method based on face recognition.

[0060] like Figure 3 As shown, the information prompting device 100 based on face recognition includes a module calling unit 110, a module identifying unit 120, a feature extracting unit 130 and an information prompting unit 140.

[0061] The module calling unit 110 is used to call a preset face recognition module if it is detected that the vehicle is started.

[0062] In this embodiment, the vehicle system is an important part of the vehicle, which integrates multiple functions such as navigation, entertainment, communication, and vehicle status monitoring. The performance and function of the vehicle system determine the intelligence level of the vehicle. When the management server of the vehicle system detects that the vehicle is started by the user, the pre-set face recognition module can be directly called.

[0063] Among them, the face recognition module needs to match the vehicle computer system. The basic principle of the face recognition module is to extract and compare the features of the face image to obtain relevant character information. This process usually includes the following steps: 1. Obtain the user's facial image through a camera or other device; 2. Use a specific recognition algorithm to calculate the position of the face in the image; 3. Extract key feature points or feature vectors from the detected user's facial image. These feature points may include the outline of the face, the position of the eyebrows, the distance between the eyes, etc. The feature vector is the result of the numerical representation of these feature points; 4. Compare the extracted features with the pre-stored facial features. The comparison method may include calculating the similarity of the feature points or matching the feature vectors, etc. The comparison result will produce a similarity or matching score; 5. Determine whether the recognition is successful based on the comparison result and output the recognition result.

[0064] The face recognition model can be integrated based on the algorithm in the face recognition algorithm library, or it may be based on the model in the open source computer vision library, such as OpenCV, SeetaFace6 and other open source libraries. When selecting a specific face recognition model, it is necessary to consider multiple factors, such as recognition accuracy, real-time performance, security, compatibility and development cost; at the same time, it is also necessary to match it according to the specific requirements of the car manufacturer to ensure that the selected model can meet the actual needs of the car manufacturer.

[0065] The module identification unit 120 is used to control the face recognition module to perform face recognition on the user to obtain corresponding face recognition information, wherein the face recognition information at least includes user identification information.

[0066] In this embodiment, after calling the face recognition module, the management server can perform face recognition on the user, thereby obtaining corresponding face recognition information. Through the user identification information contained in the face recognition information, it can be determined whether the user has the right to use and call the feature information associated with the user. Among them, the user identification information can be the user's account information, or it can be information that can uniquely identify the user, such as the phone number used by the user when registering, which is not limited in this embodiment.

[0067] The feature extraction unit 130 is configured to obtain user feature information associated with the user feature information from the preset information database if the user feature information is located in the preset information database.

[0068] In this embodiment, the management server can determine whether the user identification information is located in a preset information database. The preset information database includes the user's characteristic information. For example, usually one user corresponds to one user account information. The user account information can be used as the user's identification information and can be associated with other characteristic information of the user, such as the user's ID number, the user's operating habits, the time and path of the user's use of the vehicle, the driving conditions of the vehicle, etc. In particular, the user's characteristic information can be the owner, ID card, phone number provided when purchasing the vehicle, or the name, ID card, phone number, face and other information provided when registering the vehicle control App. At the same time, it is also necessary to confirm that the above user data is publicly available after being stored in the information database.

[0069] The information prompting unit 140 is used to parse the acquired user characteristic information and call a function module corresponding to the user characteristic information to perform corresponding information prompting.

[0070] In this embodiment, the management server can also parse the acquired user characteristic information, where different characteristic information may correspond to different functional modules, and different functional modules are used to implement prompts for user information. For example, the user's characteristic information may be the user's birthday information, and through the birthday information, a screen display module can be called according to a pre-set rule to generate and display specific blessing information, which can improve the user's experience.

[0071] In one embodiment, the user characteristic information includes an ID number, and the information prompt unit 140 also includes the following units: an information identification unit, used to parse and identify the ID number to obtain the user's birthday information and gender information; a target prompt unit, used to send the identified birthday information and gender information to a preset data processing module to obtain target prompt information; an information sending unit, used to send the target prompt information to the information prompt module of the vehicle system for information prompting.

[0072] If the user characteristic information includes an ID number, since the 7th to 14th digits of the ID number represent the date of birth, the 17th digit of the ID number can be used to distinguish the gender, if it is an odd number, it is male, and if it is an even number, it is female. When the ID number is parsed and identified to obtain the user's birthday information and gender information; after the user's birthday information and gender information are sent to a preset data processing module, the data processing module can call the target prompt information that matches the user's birthday information and gender information according to the preset rule information. If it is detected that it is the user's birthday, birthday-related blessing information is called, and the blessing information related to the user's gender is adjusted according to the user's gender.

[0073] In a further embodiment, the target prompt information includes birthday blessing information, and the target prompt unit includes the following units:

[0074] An information judgment unit is used to send the identified birthday information to a preset data processing module to determine whether the current date matches the user's birthday information; a module control unit is used to control the preset data processing module to generate corresponding birthday blessing information according to the gender information if there is a match.

[0075] Among them, when the target prompt information is birthday blessing information, the data processing module is required to determine in advance whether the user's birthday information matches the current date. If it matches, the preset data processing module is controlled to generate corresponding birthday blessing information according to the gender information. For example, if the user is a female, the generated birthday blessing information is a blessing that meets the habits and needs of women. If the user is a male, a blessing related to the habits and needs of men is generated. The data processing module can perform statistical analysis, data mining, machine learning, etc. on the data to extract useful information.

[0076] In a further embodiment, the apparatus further comprises:

[0077] The state recovery unit is used to delete the relevant information for information prompt and restore the vehicle system to the default state recognized by the user if it detects that the current time does not match the user's birthday information.

It ensures the diversified transmission of information. Therefore, it is necessary to accurately control the synchronous display and playback of image information and audio information to provide efficient and intuitive information prompts.
