As shown in fig. 1a, the in-vehicle privacy protection method, system, medium, and apparatus of the present invention are applied in an application scenario of audio and video acquisition apparatuses and vehicle construction. The audio and video acquisition device is used for acquiring audio information and/or video information in the automobile, judging whether privacy behaviors exist or not, and when the privacy behaviors exist, carrying out audio and video acquisition closing, adjusting the transmittance of window glass and the like, so that the privacy of a user is automatically protected.

As shown in fig. 1b, in an embodiment, the method for protecting privacy in a vehicle according to the present invention includes the following steps:

and S11, acquiring audio information and/or video information in the vehicle, and judging whether privacy behaviors exist or not.

Specifically, audio information and/or video information is acquired based on a camera device; or based on the microphone device acquiring the audio information.

Specifically, as shown in fig. 1c, the obtaining audio information and/or video information of a user in a vehicle, and determining whether the user has a privacy behavior includes:

and step S111a, acquiring the in-vehicle video information based on the camera device. Specifically, the image pickup apparatus includes: vehicle-mounted camera. The in-vehicle video information is video information of user behaviors in the vehicle.

And step S112a, acquiring the person information in the video information based on image recognition. The character information is video information including the action behavior of the user in the vehicle. The image recognition comprises: sift algorithm (Scale-invariant feature transform, sift)), surf algorithm (accelerated up robust features transform algorithm).

And S113a, judging whether the privacy behaviors are preset or not based on the character information. Specifically, whether the action behavior corresponds to the privacy action or not is determined according to a multi-mode recognition model trained in advance and the image information. The multi-mode recognition model is obtained by training through standard privacy image information and used for judging whether the action behavior corresponding to the image information containing the action behavior of the in-vehicle user corresponds to the privacy action.

If yes, step S114a judges that there is a privacy action. Specifically, when the preset privacy behavior is determined based on the personal information, it is determined that the user has the privacy behavior.

Specifically, as shown in fig. 1d, the obtaining audio information and/or video information of a user in a vehicle, and determining whether the user has a privacy behavior includes:

and step S111b, acquiring audio information in the vehicle based on the audio acquisition device. Specifically, the audio acquisition device is an acquisition device for acquiring audio information in the vehicle. The audio acquisition device is preferably a microphone.

And step S112b, converting the audio information into character information. Specifically, the audio information is converted into text information based on a preset voice-to-text algorithm. Or converting the audio information into character information based on the speech recognition APP. For example, the speech recognition APP is a boomerang speech APP.

And S113b, identifying whether the text information contains preset privacy keywords. Specifically, the privacy keyword is set in advance. The privacy keywords include: changing clothes, nursing, etc. And judging whether the text information contains preset privacy keywords or not, and specifically, determining whether the text information contains corresponding privacy keywords or not according to a pre-trained text recognition model and the text information. The pre-trained character recognition model is a model which is obtained by training through standard privacy keyword information and is used for judging whether the preset privacy keywords exist in the character information or not.

And step S114b, if yes, judging that the privacy behavior exists. Specifically, when a preset privacy keyword is identified in the text information, a privacy behavior is judged.

And S12, if yes, sending an audio and video acquisition closing instruction.

Specifically, an audio/video acquisition closing instruction is sent to the audio acquisition device, so that the audio acquisition device stops audio/video acquisition.

And S13, if yes, stopping transmitting the audio and video data to the cloud server.

Specifically, under normal conditions, audio and video data can be uploaded to the cloud server. However, when the user has a privacy behavior, the user is not suitable for uploading the privacy behavior to the cloud server, and the privacy of the user may be violated.

And S14, if yes, sending a color change instruction to adjust the transmittance of the vehicle window glass to a preset transmittance.

Specifically, the sending a color change instruction to adjust the transmittance of the window glass to a preset transmittance includes: and providing a preset voltage or current to the window glass based on the color change instruction, so that the window glass adjusts the transmittance of the window glass to a preset transmittance corresponding to the preset voltage or current.

Specifically, the vehicle window glass is a color-changeable glass which can change the light transmission degree through voltage or current. And sending preset voltage or current to the window glass based on the color change instruction so as to enable the transmittance of the window glass to reach the preset transmittance.

Specifically, the method further comprises the step of judging the occurrence position of the privacy behavior based on the audio information or the audio and video data; acquiring a vehicle window glass corresponding to the occurrence position based on the occurrence position; and the color change instruction specifies to adjust the transmittance of the corresponding vehicle window glass to a preset transmittance. For example, the occurrence position of the privacy behavior on a rear seat of the vehicle is judged through audio and video data, the window glass corresponding to the occurrence position is acquired as the rear window glass and the rear windshield glass based on the occurrence position, and the color change occurrence instruction specifies and adjusts the transmittance of the corresponding rear window glass and the rear windshield glass to the preset transmittance.

Specifically, the method further comprises the step of sending out notification information to enable a user to know when the privacy behaviors exist. The notification information includes: the method comprises the following steps of audio and video acquisition closing notification, audio and video data transmission stopping notification, current window glass transmittance value notification and privacy behavior name notification. The name of the privacy action is a name of an action corresponding to the specific privacy action, for example: nursing breast, changing clothes, etc. Therefore, the user can master the specific privacy state, know that the privacy of the user is protected, feel more safe and know and control the condition of the vehicle more comprehensively.

Specifically, the method further comprises sending an inquiry instruction, wherein the inquiry instruction comprises: the user is asked whether the original glass transmittance needs to be restored or whether the current transmittance will affect the field of view of the vehicle driving. Therefore, the feedback of the user can be acquired in time, and inconvenience is prevented from being brought to the user.

Specifically, the method further comprises the steps of obtaining a preset restarting instruction, and restarting audio and video acquisition based on the preset restarting instruction. The preset restart instruction may be issued based on a voice instruction of the user, or may be automatically issued after a preset time interval. For example, after the transmittance of the window glass is adjusted to the preset transmittance for a preset time interval, a preset restart instruction is automatically issued. Or when a voice restarting command of the user is received, the voice restarting command is a preset voice restarting command. Therefore, the transmittance of the window glass is adjusted to the original transmittance in time, normal audio and video acquisition is recovered, audio and video data are transmitted to the cloud server, and normal use of the vehicle is recovered in time.
