[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0046] In a first aspect, an embodiment of the present application provides a vehicle sound effect adjustment method.

[0047] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the vehicle sound effect adjustment method of the present application. Figure 1 As shown, the vehicle sound effect adjustment method includes:

[0048] Step S10, determining a user to perform eye tracking according to the sound field of the audio output by the vehicle audio system.

[0049] In this embodiment, the sound field refers to the spatial range covered by sound energy, that is, the field range where sound waves exist. According to the sound field of the audio output by the vehicle audio system, the user who performs line of sight tracking is determined from the passengers in the vehicle. For example, if the sound field of the audio output by the vehicle audio system is near the driver, the driver is determined as the user who performs line of sight tracking, and a sound effect adjustment service based on line of sight tracking is provided to the driver. In vehicle application scenarios, there are often multiple drivers and passengers in the vehicle. If each driver and passenger is blindly treated as a user for line of sight tracking and the sound effects of the audio system are adjusted, conflicts may occur, resulting in a poor user experience. However, by determining the user who performs line of sight tracking from the passengers in the vehicle according to the sound field of the audio output by the vehicle audio system, a sound effect adjustment service based on line of sight tracking can be provided to the passengers in a targeted manner, which is more personalized.

[0050] Step S20: Tracking the determined sight direction of the user.

[0051] In this embodiment, the corneal reflection method can be used to track the user's line of sight to obtain the tracked line of sight direction of the user. Specifically, an infrared light source can be used to illuminate the user's eyes to form a reflected light spot (i.e., Purkinje spot) on the user's cornea, and the image of the Purkinje spot and the pupil is captured by a camera. The center positions of the Purkinje spot and the pupil are extracted through image processing technology, and then the line of sight direction and gaze point of the user are calculated based on the relative position change between them and the geometric model of the eyeball.

[0052] Step S30, determining target sound effect parameters according to the user's sight direction and the interior layout of the vehicle.

[0053] In this embodiment, the in-vehicle layout, that is, the positions of various objects in the vehicle, such as the front central control screen, the rear entertainment screen and the windows, etc., can be determined based on the user's line of sight combined with the in-vehicle layout, and the object the user is looking at can be determined. The target sound effect parameters can be determined based on the different objects the user is looking at. For example, if the object the user is looking at is the front central control screen, the target sound effect parameters corresponding to the front central control screen can be determined, and the volume of applications in the front central control screen, such as navigation, can be increased by adjusting based on the target sound effect parameters.

[0054] Step S40, adjusting the sound effect parameters of the vehicle audio to target sound effect parameters.

[0055] In this embodiment, the sound effect is the effect achieved by the sound, and the sound effect parameters can be divided into volume parameters, sound field parameters and equalizer parameters corresponding to each channel, etc. The purpose of adjusting the volume, timbre and sound field position of the sound is achieved by adjusting the sound effect parameters, so as to achieve various sound effects, such as original sound, human voice, jazz, rock and classic sound effects, such as various environmental sound effects such as halls, opera houses, cinemas and caves, and the current sound effect parameters of the vehicle audio are adjusted according to the target sound effect parameters determined in step S30. For example, in the above step S30, the target sound effect parameters corresponding to the front row central control screen are determined, and the current sound effect parameters of the vehicle audio are adjusted to the target sound effect parameters corresponding to the front row central control screen. It should be noted that the user's line of sight can be continuously tracked, and the sound effect parameters can be adjusted in real time according to the changes in the tracked user's line of sight direction. In addition, the user can be given instant feedback by outputting voice prompts of the changes in the sound effect or performing visual prompts (such as indicators on the screen), so that the user can understand the current state of the sound effect in time, so that the user can better adjust the sound effect of the vehicle.

[0056] In this embodiment, based on the sound field of the audio output by the vehicle audio system, the user who is tracking the line of sight is determined from the passengers in the vehicle, and a sound effect adjustment service based on line of sight tracking can be provided to the passengers in a targeted manner, which is more personalized. The corneal reflection method is used to track the user's line of sight, and the object the user is looking at is determined based on the user's line of sight combined with the layout of the vehicle. The target sound effect parameters are determined based on the different objects the user is looking at, and then the sound effect of the vehicle audio is automatically adjusted. Compared with the existing basic sound effect adjustment method, a new convenient, intelligent and personalized sound effect adjustment method can be provided for the passengers in the vehicle. In addition, the sound effect adjustment method based on line of sight does not require the user's active intervention, can avoid the driver adjusting the sound effect through manual buttons and voice interaction, etc., and can improve the safety of the vehicle during driving.

[0057] Further, in one embodiment, referring to Figure 2 , Figure 2 For this application Figure 1 The detailed flow chart of step S10 is as follows: Figure 2 As shown, step S10 includes:

[0058] Step S101, if the sound field of the audio output by the vehicle audio system is within a preset range of the entire vehicle, all passengers in the vehicle are determined as users for line of sight tracking;

[0059] Step S102, if the sound field of the audio output by the vehicle audio system is within a first preset range of the driver's position, the driver is determined as a user to be tracked;

[0060] Step S103: If the sound field of the audio output by the vehicle audio system is within a second preset range of the rear entertainment screen position, the rear passenger is determined as a user for line of sight tracking.

[0061] In this embodiment, the sound field refers to the spatial range covered by sound energy, that is, the field range where sound waves exist. The intelligent audio system in the vehicle usually has multiple speakers, and each seat has several speakers to adjust the sound field, which can be adjusted independently according to the needs of each seat occupant. Therefore, according to the sound field of the audio output by the vehicle audio, the user who performs eye tracking is determined from the passengers in the vehicle, and the sound effect adjustment service based on eye tracking is provided to the passengers in a targeted manner. If the sound field of the audio output by the vehicle audio system is within a preset range of the entire vehicle, that is, it belongs to the music for the entire vehicle, then all drivers and passengers in the vehicle will be determined as users performing line of sight tracking, and sound effect adjustment services based on line of sight tracking will be provided to all drivers and passengers. If the sound field of the audio output by the vehicle audio system is within a certain range near the driver's position, for example, the audio output by the vehicle audio system is the audio output by the car navigation, and its sound field is within a certain range near the driver's position, then the driver will be determined as a user performing line of sight tracking, and a sound effect adjustment service based on line of sight tracking will be provided to the driver, such as increasing the volume of the car navigation through sound effect adjustment. If the sound field of the audio output by the vehicle audio system is within a certain range near the rear passenger positions, for example, the audio output by the vehicle audio system is the audio output by the rear entertainment screen, and its sound field is within a certain range near the rear passenger positions, then the rear passengers will be determined as users performing line of sight tracking, and sound effect adjustment services based on line of sight tracking will be provided to the rear passengers, such as increasing the volume of the rear entertainment screen through sound effect adjustment.

[0062] Further, in one embodiment, referring to Figure 3 , Figure 3 For this application Figure 1 The detailed flow chart of step S30 is as follows: Figure 3 As shown, step S30 includes:

[0063] Step S301, determining the object the user is looking at based on the user's line of sight and the layout inside the vehicle;

[0064] Step S302: searching a preset mapping table according to the object the user is gazing at to determine target sound effect parameters, wherein the preset mapping table includes a correspondence between the object the user is gazing at and the target sound effect parameters.

[0065] In this embodiment, the in-vehicle layout, that is, the positions of various objects in the vehicle, such as the front central control screen, the rear entertainment screen and the windows, etc., in the vehicle, can be determined according to the user's line of sight combined with the in-vehicle layout, and the object the user is looking at can be determined. The preset mapping table is searched according to the object the user is looking at to obtain the target sound effect parameters. For example, the object the user is looking at is the front central control screen. By searching the mapping table, the target sound effect parameters corresponding to the object the user is looking at is the front central control screen. The preset mapping table can be customized in advance. For example, the driver and passengers can use the terminal to set the corresponding target sound effect parameters when their line of sight is looking at an object according to their needs, thereby making the sound effect adjustment based on line of sight tracking highly personalized.

[0066] Furthermore, in one embodiment, the vehicle sound effect adjustment method further includes:

[0067] When it is detected that the multiple users are looking at each other and a conversation voice is recognized through the microphone, it is determined that the multiple users looking at each other are having a conversation, and the volume of the speakers within the third preset range of the multiple users looking at each other is reduced;

[0068] When it is detected that the user is using a mobile phone and the microphone recognizes that the mobile phone is playing sound, it is determined that the user is using the mobile phone audio, and the volume of the speaker within the fourth preset range of the user's position is reduced;

[0069] When it is detected that the user has closed his eyes and the duration of closing his eyes exceeds a preset duration, it is determined that the user is in a resting state, and the volume of the speaker within a fifth preset range of the user's position is reduced.

[0070] In this embodiment, by tracking the gaze directions of multiple users or based on video image analysis, it is detected that the gazes of multiple users are facing each other, and the conversation voice is detected by the vehicle-mounted microphone, so it can be determined that the multiple users who are facing each other are having a conversation. At this time, the volume of the speakers within a certain range near the positions of the multiple users who are facing each other can be reduced, so that the conversation between the driver and passengers can be smoother. By tracking the user's gaze or based on video image analysis, it is detected that the user is using a mobile phone, and the vehicle-mounted microphone recognizes that the mobile phone is playing sound, so it can be determined that the user is using mobile phone audio. At this time, the volume of the speakers within a certain range of the user's position can be reduced to improve the user's experience when using mobile phone audio. By tracking the user's gaze or based on video image analysis, it is detected that the user has closed his eyes and the duration of the eyes closing exceeds a preset duration. For example, if it is detected that the user's gaze is continuously lost for more than a certain period of time, it can be determined that the user is in a resting state. At this time, the volume of the speakers within a certain range of the user's position can be reduced to provide the user with a good rest environment.

[0071] Furthermore, in one embodiment, the vehicle sound effect adjustment method further includes:

[0072] When it is detected that the in-car game is turned on and the user's line of sight is directed towards the in-car game, the volume corresponding to the character or object in the game that the user's line of sight is focused on is increased.

[0073] In this embodiment, when it is detected that the in-car game is turned on and the user's line of sight is directed towards the in-car game, it is determined that the user is in the game scene, and the volume corresponding to the character or object in the game that the user's line of sight is focused on can be increased, providing the user with a more immersive sound experience through a sound adjustment algorithm based on line of sight tracking.

[0074] Furthermore, in one embodiment, the vehicle sound effect adjustment method further includes:

[0075] Based on the tracked user gaze direction data, the user's behavior is predicted through a machine model;

[0076] Adjust the sound parameters of the vehicle audio system based on predicted user behavior.

[0077] In this embodiment, the continuously tracked user line of sight direction data is input into a pre-trained machine model to predict the user's next behavior, wherein the specific machine model type and structure are not limited here. According to the predicted user's next behavior, the sound effect parameters of the vehicle audio are adjusted, so that the line of sight-based sound effect adjustment is forward-looking and can provide the user with line of sight-based sound effect adjustment services in advance. For example, based on the continuously tracked user line of sight direction data input, the machine model recognizes that the user will take a nap every once in a while, and predicts that the user will fall asleep soon afterwards, so that the machine model can intervene in advance and turn off the sound field within a certain range of the user's position as soon as possible, so that the user can enter a resting state as soon as possible.
