Fig. 1 illustrates a flow diagram of a method of recommending multimedia information, according to some embodiments of the present disclosure. As shown in fig. 1, some embodiments of the present disclosure provide a method 100 for recommending multimedia information, which may be applied to a vehicle such as an airplane, a high-speed rail, and an automobile. For convenience of explanation, the method will be described below as applied to a vehicle as an example. The vehicle may include a front row of seats, which may include a driver's seat, a passenger seat, and a rear row of seats, which may include a plurality of passenger seats. A plurality of multimedia interaction devices may be disposed in the vehicle, and each multimedia interaction device may be located in front of a driver's seat, a passenger seat, and one of a plurality of passenger seats, for example, one multimedia interaction device may be disposed in front of the passenger seat, and one multimedia interaction device may be disposed in front of each passenger seat in the rear row. The multimedia interaction device may comprise a display screen, or a tablet computer or the like capable of presenting at least one of pictures, text, video and sound. The method 100 includes the following steps S101 to S104.

In step S101, a face image of a passenger seated in a vehicle is acquired.

The manner of acquiring a facial image of a passenger seated within a vehicle may include: the image of the face of the passenger is acquired by an image pickup apparatus installed in the vehicle. The camera device may be a camera, camcorder, or the like capable of taking pictures. It is understood that the camera device may be provided separately from the multimedia interaction device or may be integrated with the multimedia interaction device. In some embodiments, each multimedia interaction device is integrated with a camera device, and the camera device can be arranged to face the face of the passenger, that is, after the passenger is seated, the camera device can accurately capture the face of the passenger and capture an image of the face of the passenger.

In step S102, an attribute category corresponding to the passenger is determined from a plurality of attribute categories based on the face image of the passenger.

The plurality of attribute categories may include a plurality of age categories and/or at least two gender categories. For example, in some embodiments, the plurality of attribute categories respectively include: child category, geriatric category, male category, and female category.

It is understood that the facial image of the passenger can be processed according to the facial image of the passenger, for example, a common image processing method such as a neural network algorithm is adopted to extract key points of a human face and find out the positions of eyes, a nose, a mouth and the like of the human face, so that the approximate age bracket, the gender and the like of the passenger can be obtained according to the facial image of the passenger. For example, if it is confirmed from the face image of the passenger that the passenger is about 5 to 8 years old, the attribute category corresponding to the passenger may be set as the child category.

In some embodiments, the step of determining the attribute category corresponding to the passenger may include substeps one and two below.

In sub-step one, facial features of the passenger are identified from the facial image of the passenger. The facial features of the passenger may include: face contour size, facial feature size and location, facial texture, etc.

In the sub-step two, according to the facial features of the passenger, the attribute class corresponding to the passenger is determined from the multiple attribute classes.

It will be appreciated that the general nature of facial features varies for different classes of people, for example for children, where the facial contour is small and rounded, the bones of the cranial portion appear large and the cranial portion appears small. For example, in women, the facial edges are soft and rounded, the frontal nodules are prominent compared with men, the eye sockets are bigger than men, the nasal bones and the mandible are atrophied, and the whole head shape appears slightly smaller. For example, men have sharp corners, rigid lines, and a higher slope of the eyebrow arch than the forehead of women. The orbit is smaller than the female, and the nasal bone and the mandible are more developed. Also, the adult eye position is generally above and below the head 1/2, with the outer canthus being equidistant from the corners of the mouth and tragus. The position of the five sense organs of the aged was slightly shorter than 1/2 below the eyes due to the loss of teeth. The position of the five sense organs of the child is slightly longer than 1/2 on the face above the eyes because the chin is not fully extended.

Therefore, the attribute category corresponding to the passenger can be determined according to the facial features identifying the passenger.

In step S103, a multimedia information mode that recommends multimedia information to the passenger is selected from the plurality of multimedia information modes according to the attribute category corresponding to the passenger and the correspondence between the plurality of attribute categories and the plurality of multimedia information modes.

The plurality of multimedia information modes include at least two of an old man mode, a child mode, a teenager mode, a middle-aged mode, a male mode and a female mode, and each multimedia information mode may be set corresponding to one attribute category. In some embodiments, the plurality of attribute categories respectively include: child category, geriatric category, male category, and female category. The plurality of multimedia information modes respectively include a child mode, an old man mode, a man mode, and a woman mode.

For example, if it is determined in step S102 that the attribute category corresponding to the passenger is a child category, the child mode may be selected to recommend multimedia information to the passenger.

By dividing the attribute categories corresponding to the passengers, the multimedia information according with the preference of the passengers can be better provided for the passengers.

In step S104, according to the selected multimedia information mode, multimedia information corresponding to the selected multimedia information mode is presented on a multimedia interaction device installed in a vehicle in association with a seat in which a passenger is seated.

The multimedia information corresponding to the selected multimedia information mode may include: a display interface and/or multimedia content corresponding to the selected multimedia information mode. The display interface refers to the interaction style displayed by the screen of the multimedia interaction device, such as colors, icons or character images. The multimedia content may include animations, movies, television shows, songs, news, web hotspots, short videos, novels, and the like. For example, for the child mode, the display interface may be designed to be a multi-color cartoon style, and the recommended multimedia content on the interface may include cartoons, children's songs, and children's stories. For example, for a lady model, the display interface design may be more beautiful and warm in color, and the recommended multimedia content on the interface may include beauty information, emotional episodes and entertainment news. For example, for the male model, the display interface is designed to be of a commercial style and cool in color, and the recommended multimedia content on the interface can include financial information, action films and sports news. For another example, for an elderly passenger, the display interface is designed to be a Chinese style, and the multimedia content recommended on the interface is art, revolutionary movies, and classical songs. By recommending multimedia information containing different display interfaces and/or multimedia contents, the preference of most passengers can be met, and the passenger riding experience is improved.

In this embodiment, after a passenger sits down, the passenger's facial image is acquired, the attribute type of the passenger is determined according to the facial image, the multimedia information mode for recommending multimedia information to the passenger is determined according to the attribute type corresponding to the passenger and the corresponding relationship between the attribute types and the multimedia information modes, and then the recommended multimedia information is displayed on the multimedia interaction device.

Fig. 2 illustrates a flow diagram of a method of recommending multimedia information, according to some embodiments of the present disclosure. As shown in fig. 2, a method 200 for recommending multimedia information according to some embodiments of the present disclosure further includes the following steps S201 to S204 based on the above embodiments.

In step S201, in response to the facial image feature library not including the recognized facial features, the recognized facial features are stored in the facial image feature library, and an identification corresponding to the recognized facial features is created for the passenger.

It will be appreciated that the facial features of each person are different and therefore the facial features can also be used for identification. The facial image feature library may include facial features of all passengers riding the vehicle.

For a passenger sitting in a seat of the vehicle for the first time, a facial image of the passenger may be obtained, facial features of the passenger may be identified, and the facial features of the passenger may be stored in a facial image feature library, while an identification corresponding to the facial features of the passenger, such as passenger 1, passenger 2, or passenger 3, etc., may be created for the passenger.

Therefore, whether the passenger is seated for the first time can be determined by the facial image of the passenger, regardless of whether the passenger is seated in any seat of the vehicle.

In step S202, the operation record of the passenger on the multimedia information for a predetermined period of time is stored in the storage device.

The preset time period may be a time when the passenger sits on the seat.

It can be understood that the multimedia information recommended to the passenger through the multimedia interaction device can be the multimedia information statistically obtained by the big data and favored by the passenger in the attribute category. For example, it is generally considered that a child likes an animation, but a small number of children like a sports program, and after the animation is recommended, the child may manually switch to other multimedia information such as the sports program that meets the preference of the child, and at this time, the operation record of the multimedia information in the predetermined time period may be stored in the storage device.

The stored operation record may include a viewing duration, a number of clicks, etc. for a certain type of multimedia information.

In step S203, the preference of the passenger is determined from the stored operation record.

The preference of the passenger for a certain type of multimedia information can be judged according to the stored operation records, for example, animation films are recommended to the passenger, but the number of clicks is small, and the watching time is short, so that the passenger can be indicated not to like the animation films. Conversely, if the passenger clicks on the sports program more and watches a longer time, it may indicate that the passenger prefers the sports program.

In some embodiments, the step S203 further comprises: and determining the operation frequency of the passenger on the multimedia information from the collected operation records. And determining the preference of the passenger according to the operation frequency of the passenger on the multimedia information. The operation frequency may include the number of clicks, etc., which may accurately reflect the preference of the passenger.

In step S204, a correspondence between the identity of the passenger and the preferences of the passenger is established. I.e. binding the preferences of the passenger to the identity of the passenger, e.g. passenger 1-favorite sports program.

By establishing the identity of the passenger and the preference of the passenger, the preference of the passenger can be quickly obtained, so that multimedia information conforming to the preference of the passenger can be recommended to the passenger, and the riding experience is further improved.

FIG. 3 illustrates a flow diagram of a method of recommending multimedia information, according to some embodiments of the present disclosure. As shown in fig. 3, the method 300 for recommending multimedia information according to some embodiments of the present disclosure further includes the following steps S301 to S304 on the basis that the correspondence between the identity of the passenger and the preference of the passenger is established.

In step S301, in response to the facial image feature library including the recognized facial features, an identification corresponding to the recognized facial features is determined.

In step S302, the preferences of the passenger are determined according to the correspondence between the identity of the passenger and the preferences of the passenger.

In step S303, multimedia information corresponding to the preference of the passenger is acquired.

In step S304, multimedia information corresponding to the preference of the passenger is presented on the multimedia interacting device.

It will be appreciated that if the passenger does not first ride the vehicle, i.e., the facial image feature library already has stored facial features of the passenger, the identity of the passenger, such as passenger 1, may be determined. The preferences of the passenger, i.e. the categories of the multimedia information preferred by the passenger, are looked up based on the passenger identity, e.g. the passenger 1-favorite sports program is determined based on the correspondence between the passenger identity and the passenger preferences. Then, multimedia information of the sports program category can be obtained, the sports program is displayed on the multimedia interaction equipment facing the passenger, so that when the passenger takes the vehicle again and uses the multimedia interaction equipment, the multimedia interaction equipment recommends the multimedia information corresponding to the preference of the passenger according to the established corresponding relation between the identity of the passenger and the preference of the passenger, the accuracy of the recommended multimedia information conforming to the preference of the passenger is further improved, and the user experience is improved.

In some embodiments, the facial image feature library may be located on a cloud server or on a multimedia interaction device. When the vehicle is arranged on the multimedia interaction device, the facial features of the passenger can be stored and the identity identification can be established for the vehicle under the poor network condition. And when the system is located in the cloud server, a large amount of passenger data can be stored.

In addition, the facial image feature library can be stored in the multimedia interaction device and the cloud server at the same time, the multimedia interaction device can store the latest 50 passenger data, all passenger data taking the vehicle can be stored in the cloud server, if the facial image feature library in the multimedia interaction device does not include the facial features of a certain passenger, whether the facial features of the passenger are included can be searched from the facial image feature library of the cloud server, the cloud server is combined with the multimedia interaction device, a large amount of passenger data can be stored, and the multimedia interaction device can be used for recommending multimedia information under the condition of poor network.

Similarly, the storage device may also be located in the cloud server or in the multimedia interaction device. When the multimedia information storage device is arranged on the multimedia interaction device, the vehicle can also store the operation records of the passengers on the multimedia information under the condition of poor network. And when the system is located in the cloud server, a large amount of operation records of passengers can be stored.

In addition, the storage device can also be stored in the multimedia interaction device and the cloud server at the same time, the multimedia interaction device can store 100 recent operation records of passengers, and more operation records of all passengers who take the vehicle can be stored in the cloud server, so that the cloud server and the multimedia interaction device are combined, a large number of operation records of the passengers can be stored, and the multimedia interaction device can be used for recommending multimedia information under the condition of poor network.

In some embodiments, for private vehicles such as private cars, the facial image feature library and the storage device can be stored in the multimedia interaction device and can be backed up through the cloud server, so that multimedia information conforming to preferences of passengers can be recommended to the passengers under the condition of poor network.

And for public transport means such as aircraft, high-speed railway, facial image feature library and storage device can mainly rely on the high in the clouds server to save, and the passenger data in this transport means's a journey can be saved to the multi-media interaction device. The passenger may also be recommended multimedia information that meets his preferences when he takes another public transportation.

In some embodiments, step S101 further comprises: the facial images of the passenger are acquired in real time or at set time intervals. The set time interval may be 5 seconds, 10 seconds, etc., and may be set according to actual conditions. It can be understood that, since the seat in the vehicle is not a fixed seat, for example, in long-distance driving, the passenger in the main driving seat and the passenger in the assistant driving seat can drive alternately, when the positions of the two are exchanged, by acquiring the facial images of the passengers in real time or at set time intervals, whether the passenger sitting in the seat changes or not can be found in time, so that the multimedia information according with the preference of the passenger can be provided more intelligently for the passenger.
