When it detects that there is no one in the car and someone attempts to enter illegally, the display device can automatically turn on and display a warning message or sound an alarm to improve the safety of the vehicle.

[0025] In summary, intelligently controlling the power on of the front and rear row display devices in the car based on whether there is someone in the car not only helps to save energy and reduce emissions, improve user experience and enhance safety, but also enables more intelligent vehicle management. With the continuous development of intelligent automobile technology, this function will gradually become one of the standard configurations of future cars.

[0026] Furthermore, the specific process of the first recognition condition and the second recognition condition is as follows: a preset recognition mark is set on each seat in the car, and the preset recognition mark model is imported into the clear in-car image information, and the preset recognition mark model and human body recognition are performed in the clear in-car image information. When the human body is recognized in the clear in-car image information, the preset recognition mark model is recognized. At this time, when the mark in the clear in-car image information that is similar to the preset recognition mark model and is greater than the preset value, it means that the preset recognition mark is recognized; When the preset identification mark model is not recognized in the clear in-vehicle image information or the recognized preset identification mark area is smaller than the preset value, and a human body is recognized in the clear in-vehicle image information, it indicates that the first identification condition is stored; When a complete preset recognition model is recognized in the clear in-vehicle image information, it indicates that the second recognition condition is triggered.

[0027] Furthermore, the specific content of other parking space control information is to control the on-board display device at the corresponding position to turn on or off, and each preset identification mark contains the vehicle seat position information of the corresponding non-driving position. When the preset identification mark is not recognized, the vehicle seat position information of the non-driving position of the preset identification mark is synchronously transmitted back to the preset receiving terminal, and after the preset receiving terminal receives the vehicle seat information, the first control information is sent to the on-board display terminal of the corresponding vehicle seat.

[0028] The process of acquiring the driving position control information is as follows: extracting the collected vehicle information, the vehicle information including vehicle start information and driving position force information; The vehicle start information includes vehicle start and vehicle not start; When the vehicle start information is vehicle start, and the driving position force information is greater than the preset value for a period of time a1, the driving position control information is generated; When the vehicle startup information indicates that the vehicle is not started, and the driving position force information is greater than the preset value for a period of time a2, the driving position control information is generated, a1<a2; The driver's seat control information specifically controls the startup and operation of the vehicle-mounted display device at the driver's seat.

[0029] The second control information includes driving position display device control information and non-driving position display device control information; The specific process of obtaining the control information of the non-driving position display device is as follows: extracting the collected in-vehicle information, which includes the in-vehicle brightness information, the current number of people in the vehicle, and the number of parking spaces in the vehicle except the driving position; Then extract the display device information, the display device information includes the display device brightness information and the display device operation status information; Calculate the difference between the number of parking spaces excluding the driver's seat and the number of people in the vehicle to obtain the number difference; When the number difference is a non-zero value, the display device operation status information corresponding to the position of the non-riding person is extracted. When the display device operation status information at this time is the display device power-on state, the non-driving position display device control information is generated. When the display device operation status information at this time is the display device power-off state, no information is generated. At this time, the specific content of the non-driving position display device control information is to control the display device of the unoccupied position to shut down; When the brightness information inside the vehicle is greater than the preset value and the brightness information of the display device is less than the preset value, the non-driving position display device control information is generated. At this time, the specific content of the non-driving position display device control information is to control the display device to increase its display brightness; When the interior brightness information is less than the preset value and the display device brightness information is greater than the preset value, non-driving display device control information is generated. At this time, the specific content of the non-driving display device control information is to control the display device to reduce its display brightness.

[0030] The process of acquiring the control information of the driver's seat display device is as follows: extracting the collected in-vehicle information, extracting the in-vehicle brightness information from the in-vehicle information, and then extracting the out-vehicle information, where the out-vehicle information is the brightness information of the outside environment, and then extracting the display brightness information of the display device of the driver's seat; When the brightness information inside the vehicle is less than the preset value, the brightness information outside the vehicle is less than the preset value, and the display brightness information of the display device at the driver's seat is greater than the preset value c1, the driver's seat display device control information is generated; When the brightness information inside the vehicle is greater than the preset value, the brightness information outside the vehicle is greater than the preset value, and the display brightness information of the display device at the driver's seat is less than the preset value c2, the driver's seat display device control information is generated; c1>c2; Intelligently adjusting the brightness of the front and rear row display devices according to the brightness inside the car, the brightness outside the car and the brightness of the on-board display device has the following significant benefits: Improve driving and riding experience: Reduce visual fatigue: In low-light or high-light environments, automatically adjusting the brightness of display devices can ensure that screen content is clearly visible, reducing the visual fatigue of drivers and passengers caused by prolonged screen viewing.

[0031] Enhanced comfort: Through intelligent adjustment, the brightness of the display device can be coordinated with the ambient light, providing a more comfortable visual environment for passengers in the car and improving the overall riding experience.

[0032] Protect vision health: Prevent eye damage: In strong light, too high screen brightness may cause eye discomfort or even damage; in dim light, too low screen brightness may increase the burden on the eyes. Intelligent adjustment can avoid both situations and protect passengers' vision.

[0033] Improve driving safety: Reduce glare interference: When the light outside the car is strong, such as direct sunlight or high beams from oncoming vehicles, automatically adjusting the brightness of the display device can reduce the glare reflected from the screen, reduce interference with the driver's vision, and improve driving safety.

[0034] Optimize nighttime driving vision: At night or in low-light environments, automatic brightness adjustment can make the display device softer, reduce visual interference with the road ahead, and help drivers better observe road conditions.

[0035] Achieve energy saving and consumption reduction: Reduce energy consumption: By intelligently adjusting the brightness of the display device, its working state can be adjusted according to actual needs, avoiding unnecessary power consumption and achieving the goal of energy saving and consumption reduction.

[0036] Intelligent management and convenience: Intelligent linkage: The vehicle-mounted system can automatically adjust the brightness of the display device according to the changes in light inside and outside the vehicle, without the need for manual operation by the driver or passengers, thus improving the convenience of use.

[0037] Personalized settings: Some high-end models may allow users to personalize brightness adjustments according to their preferences, further improving the level of intelligence.

[0038] In summary, intelligently adjusting the brightness of the front and rear row display devices according to the brightness inside the car, the brightness outside the car and the brightness of the on-board display devices not only helps to improve the driving and riding experience, protect vision health, and improve driving safety, but also achieves energy saving and consumption reduction and intelligent management. This function is one of the important directions for the development of modern automobile intelligence.

[0039] The specific process of obtaining the third control information is as follows: Extract the collected in-vehicle image information, perform face recognition processing on the in-vehicle image information, and after recognizing the face, analyze and process the face image to obtain gender information and age information; Then, the gender and age information is imported into a preset database, and after the playback content of the person of the corresponding gender and age is retrieved from the preset database, the third control information is generated. The preset database stores various types of playback content.

[0040] The specific process of analyzing and processing the facial image to obtain gender information and age information is as follows: face preprocessing, face alignment: according to the coordinates of the key points of the facial features (such as eyes, nose, mouth, etc.), the detected face is aligned, including rotation, scaling, cropping, etc., to eliminate the influence of different postures and angles on the recognition results.

[0041] Normalization: Normalize the size, brightness, contrast and other parameters of the face image to improve the accuracy and stability of subsequent feature extraction.

[0042] Feature extraction: Gender feature extraction: Use a certain encoding method (such as PCA principal component analysis, LDA linear projection analysis, Gabor wavelet features combined with Adaboost+SVM classifier, etc.) to extract gender-related features from the preprocessed face image. These features may include facial contours, facial features, skin texture, etc.

[0043] Age feature extraction: The extraction of age features is relatively complex because it is difficult to accurately observe age features on the outside. It is usually necessary to learn from a large number of samples to extract age-related features, such as skin brightness, wrinkle texture, color changes, etc. These features may be automatically extracted through deep learning methods (such as convolutional neural networks (CNNs)).

[0044] Classification and identification: Gender classification: The extracted gender features are input into a gender classifier (such as SVM classifier, neural network, etc.) for classification and judgment to obtain gender information.

[0045] Age estimation: Age estimation is usually divided into two stages: estimation and detailed evaluation. In the estimation stage, the age range is roughly evaluated based on the extracted age features; in the detailed evaluation stage, model classifiers for multiple age groups are established through methods such as support vector machines (SVM), and appropriate models are selected for matching to obtain age information.

[0046] After retrieving the playback content of people of corresponding gender and corresponding age from the preset database, the playback quantity and video praise rate of the playback content are collected; The number of plays of a single content is marked as G1, and the rate of favorable comments of the content is marked as G2; Assign a correction value M1 to G1, and a correction value M2 to G2, M1>M2, M1+M2=1; The comprehensive score Gg of a single playback content is obtained through the formula G1*M1+G2*M2=Gg; Then, the comprehensive scores Gg of all played contents are extracted, and the played content corresponding to the maximum comprehensive score Gg is selected as the priority played content. After the third control information is generated, the priority played content is played immediately.

[0047] Through the above process, the user experience can be improved and personalized content can be pushed: by analyzing the age and gender of the passengers, the in-vehicle system can more accurately push content that suits their interests and hobbies, such as music, movies, news, games, etc., thereby improving the user's riding experience and satisfaction.

[0048] Emotional interaction: For passengers of different ages and genders, the in-vehicle system can design different emotional interaction methods, such as using a more friendly or professional language style to enhance the emotional connection between users and the system.

[0049] Promote the combination of education and entertainment: For child passengers, the in-vehicle system can push entertaining and educational content, such as animations, nursery rhymes, scientific knowledge, etc., which can not only meet their entertainment needs but also promote their learning and growth.

[0050] Adult entertainment and learning: For adult passengers, the in-vehicle system can provide a variety of content such as news, finance, health, travel, etc. to meet their diverse entertainment and learning needs.

[0051] Improve operational efficiency and optimize content distribution: Through intelligent push, the in-vehicle system can use limited display resources more efficiently, push the content that best meets user needs to users, and improve the efficiency and accuracy of content distribution.

[0052] Improve user stickiness: Personalized content push can enhance users' dependence and stickiness on the in-vehicle system, prompting users to use the services provided by the in-vehicle system more frequently.

[0053] Promote accurate placement of in-vehicle advertising and improve advertising effects: Accurately placing advertisements based on the age and gender characteristics of passengers can improve the targeting and effectiveness of advertising, reduce advertising waste, and improve advertising effects.

[0054] User experience optimization: Avoid pushing advertising content that is inconsistent with the user's age and gender, reduce user disgust and resistance, and improve the user's overall experience.

[0055] In summary, intelligently pushing content played on in-vehicle display devices based on the age and gender of passengers can significantly improve user experience, promote the combination of education and entertainment, improve operational efficiency, and promote the precise delivery of in-vehicle advertising. These benefits work together to improve the intelligence level and user experience of the entire in-vehicle system.
