detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Fig. 1 shows the implementation flow diagram of the method for switching the language of the vehicle navigation provided by the embodiment of the present invention, which is described in detail as follows:

In step S101, the facial image of the current driver is obtained, and the language type information matching the facial image of the current driver is searched from a database.

In the embodiment of the present invention, a camera is set at the position of the driver's seat in the vehicle, and when the vehicle navigation device is started or the vehicle is started, the face image of the current driver is acquired through the camera. After the facial image of the current driver is obtained, the language type information matching the facial image of the current driver is searched from the database. The language type may include national languages and local dialects, etc., which is not limited here. In the embodiment of the present invention, the corresponding relationship between the facial images of different drivers and the language types is recorded in the database. For example, the language corresponding to the facial image of driver A is Mandarin, and the language corresponding to the facial image of driver B is Cantonese. talk.

In step S102, if the language type information matching the facial image of the current driver is found from the database, switch the language of the car navigation to the language type corresponding to the facial image of the current driver.

In the embodiment of the present invention, if the language type information matching the facial image of the current driver is found from the database, the language of the car navigation is switched to the language type corresponding to the facial image of the current driver, thereby realizing After the car navigation is started, the language type is actively selected according to the facial image of the current driver, so that different language types can be automatically switched according to different drivers, and the driver does not need to manually select the language type of the car navigation. Repeat settings.

Fig. 2 shows the implementation flowchart of the method for switching the language of the car navigation provided by another embodiment of the present invention, referring to Fig. 2:

In step S201, obtain the facial image of the current driver, and search the language type information matching with the facial image of the current driver from the database;

In step S202, if the language type information matching the facial image of the current driver is found from the database, switch the language of the vehicle navigation to the language type corresponding to the facial image of the current driver;

In step S203, if the language type information matching the facial image of the current driver cannot be found from the database, recording is performed;

In step S204, if voice data is detected in the recorded voice data, the language type corresponding to the voice data is analyzed, and the language of the car navigation is switched to the language type corresponding to the voice data.

In the embodiment of the present invention, if no language type information matching the current driver's facial image can be found from the database, it indicates that no language type information matching the current driver is recorded in the database. In this case, the recording is started, and when voice data is detected in the recorded voice data, the language type corresponding to the voice data is analyzed, and the language of the car navigation is switched to the language type corresponding to the voice data.

As an embodiment of the present invention, if the language type information matching the facial image of the current driver cannot be found from the database, the recording is performed, and the current driver is prompted to speak in the form of voice or text, thereby quickly making the recording The voice data is included in the obtained sound data, so as to quickly switch the language of the car navigation to the same language type as the language used by the current driver.

Preferably, if the voice data is detected in the voice data obtained by recording, then analyze the language type corresponding to the voice data, and switch the language of the car navigation to the language type corresponding to the voice data as follows: if in If voice data is detected in the voice data obtained by recording, and the sound source position of the voice data is on the driving seat of the vehicle, the language type corresponding to the voice data is analyzed, and the language of the vehicle navigation is switched to the voice data corresponding language type.

As an embodiment of the present invention, if voice data is detected in the recorded voice data, it is analyzed whether the sound source of the voice data is on the driving seat of the vehicle. If the sound source position of the voice data is on the driving seat of the vehicle, then analyze the language type corresponding to the voice data, and switch the language of the car navigation to the language type corresponding to the voice data; if the sound source position of the voice data is not in the vehicle's If the driver is in the driving seat, the recording is continued until the sound data obtained by the recording includes the voice data that the sound source is located in the driving seat of the vehicle. Therefore, when there are many people in the vehicle, the language type of the car navigation is determined according to the language type used by the current driver in the driving seat, so as to avoid interference with the language selection of the car navigation by other people in the vehicle except the current driver. .

Fig. 3 shows the implementation flowchart of the method for switching the language of the car navigation provided by another embodiment of the present invention, referring to Fig. 3:

In step S301, obtain the facial image of the current driver, and search the language type information matching with the facial image of the current driver from the database;

In step S302, if the language type information matching the facial image of the current driver is found from the database, switch the language of the vehicle navigation to the language type corresponding to the facial image of the current driver;

In step S303, if the language type information matching the facial image of the current driver cannot be found from the database, recording is performed;

In step S304, if voice data is detected in the voice data obtained from the recording, analyze the language type corresponding to the voice data, and switch the language of the car navigation to the language type corresponding to the voice data;

In step S305, the corresponding relationship between the facial image of the current driver and the language type corresponding to the voice data is recorded in the database.

In the embodiment of the present invention, after analyzing the language type corresponding to the language data, the corresponding relationship between the facial image of the current driver and the language type corresponding to the voice data is recorded in the database, so that the next time the driver drives the When driving a vehicle, the language type corresponding to the driver can be quickly identified based on the driver's facial image.

Preferably, after the recording is performed and before the voice data is detected in the voice data obtained from the recording, the method further includes: switching the language of the car navigation to a specified language type.

In the embodiment of the present invention, after the recording is performed, before voice data is detected in the sound data obtained from the recording, the language of the car navigation is switched to a specified language type, which can be defaulted by the system or set by the user , is not limited here.

It should be understood that in the embodiment of the present invention, the sequence numbers of the above-mentioned processes do not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, rather than the implementation process of the embodiment of the present invention. constitute any limitation.
