[0044] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

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

[0046] In the first aspect, the embodiments of the present application provide a vehicle sound effect adjusting method.

[0047] In an embodiment, with reference to Figure 1 , Figure 1 The flowchart of the embodiment of the vehicle sound effect adjusting method of the present application is shown in the figure. As shown in the figure, the vehicle sound effect adjusting method comprises: Figure 1

[0048] Step S10, determining the user for line-of-sight tracking according to the sound field of the audio output by the vehicle sound.

[0049] ​In this embodiment, the sound field refers to the spatial range covered by sound energy, that is, the range of the field in which sound waves exist. According to the sound field of the audio output by the vehicle sound system, a user for line-of-sight tracking is determined from the passengers on the vehicle. For example, if the sound field of the audio output by the vehicle sound system is located near the driver, the driver is determined as the user for line-of-sight tracking, and a sound effect adjustment service based on line-of-sight tracking is provided for the driver. In the vehicle application scenario, there are usually multiple passengers on the vehicle. If each passenger is blindly tracked as a user for line-of-sight tracking, and then the sound effect of the sound system is adjusted, conflicts may occur, resulting in poor user experience. According to the sound field of the audio output by the vehicle sound system, a user for line-of-sight tracking is determined from the passengers on the vehicle, so that the sound effect adjustment service based on line-of-sight tracking can be provided for the passengers in a targeted manner, and the service is more personalized.

[0050] Step S20: The line-of-sight direction of the determined user is tracked.

[0051] In this embodiment, the line-of-sight of the user can be tracked by using the corneal reflection method to obtain the line-of-sight direction of the tracked user. Specifically, an infrared light source can be used to irradiate the eyes of the user to form a reflection spot (i.e., Purkinje spot) on the cornea of the user, and a camera can be used to capture the image of the Purkinje spot and the pupil. The center positions of the Purkinje spot and the pupil are extracted through image processing technology, and then the line-of-sight direction and the gaze point of the user are calculated according to the relative position change between the two positions and in combination with the geometric model of the eyeball.

[0052] Step S30: The target sound effect parameter is determined according to the line-of-sight direction of the user and the layout in the vehicle.

[0053] In this embodiment, the layout in the vehicle refers to the positions of various objects in the vehicle, such as the front center screen, the rear entertainment screen, and the windows. According to the line-of-sight direction of the user and in combination with the layout in the vehicle, the object gazed at by the user can be determined, and the target sound effect parameter is determined according to the different objects gazed at by the user. For example, if the object gazed at by the user is the front center screen, the target sound effect parameter corresponding to the front center screen can be determined, and the application in the front center screen, such as the increase of the navigation volume, is realized through adjustment based on the target sound effect parameter.

[0054] Step S40: The sound effect parameter of the vehicle sound system is adjusted to the target sound effect parameter.

[0055] In this embodiment, the sound effect is the effect of sound reaching, 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, tone, and sound field position of the sound is achieved by adjusting the sound effect parameters, so as to realize various sound effects, such as original sound, human voice, jazz, rock, and classic sound effects, such as various environmental sound effects of a hall, an opera house, a cinema, and a cave. The current sound effect parameters of the vehicle audio are adjusted according to the target sound effect parameters determined in step S30. For example, if the target sound effect parameters corresponding to the front center control screen are determined in step S30, the current sound effect parameters of the vehicle audio are adjusted to the target sound effect parameters corresponding to the front center control screen. It should be noted that the user's line of sight can be continuously tracked, and the sound effect parameters are adjusted in real time according to the change of the tracked user's line of sight direction. In addition, the user can be given immediate feedback by outputting voice prompt sound effect changes or visual prompts (such as indicators on the screen), so that the user can timely understand the current state of the sound effect, so as to better adjust the sound effect of the vehicle.

[0056] In this embodiment, the user for line-of-sight tracking is determined from the passengers in the vehicle according to the sound field of the audio output by the vehicle audio. The line-of-sight tracking-based sound effect adjustment service can be provided for the passengers in a targeted manner, and is more personalized. The line-of-sight of the user is tracked by the corneal reflection method, the object gazed at by the user is determined according to the line-of-sight direction of the user and the layout in the vehicle, the target sound effect parameters are determined according to different objects gazed at by the user, and the sound effect of the vehicle audio is automatically adjusted. Compared with the existing sound effect adjustment mode, a new convenient, intelligent, and personalized sound effect adjustment mode can be provided for the passengers in the vehicle. In addition, the line-of-sight-based sound effect adjustment mode does not require active intervention of the user, and can avoid the driver adjusting the sound effect by manually pressing the keys and voice interaction, so as to improve the safety during driving of the vehicle.

[0057] Further, in an embodiment, referring to Figure 2 , Figure 2 the detailed flowchart of step S10 in this application Figure 1 , as shown in Figure 2 , step S10 includes:

[0058] Step S101, if the sound field of the audio output by the vehicle audio is located in a preset full-vehicle range, 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 is located in a first preset range of the driver position, the driver is determined as a user for line-of-sight tracking;

[0060] Step S103, if the sound field of the audio output by the vehicle audio is located in the second preset range of the rear entertainment screen position, the rear passengers are determined as the user for gaze tracking.

[0061] In this embodiment, the sound field refers to the spatial range covered by sound energy, that is, the range of the field in which sound waves exist. The intelligent audio system in the vehicle is usually a multi-speaker, and each seat has several speakers cooperating to adjust the sound field, which can be independently adjusted according to the needs of each seat person. Therefore, according to the sound field of the audio output by the vehicle audio, the user for gaze tracking is determined from the vehicle occupants, and the gaze tracking-based sound effect adjustment service is provided for the vehicle occupants. If the sound field of the audio output by the vehicle audio is located in the preset full-vehicle range, that is, it belongs to full-vehicle music, all the vehicle occupants are determined as the user for gaze tracking, and the gaze tracking-based sound effect adjustment service is provided for all the vehicle occupants. If the sound field of the audio output by the vehicle audio is located in a certain range near the driver position, for example, the audio output by the vehicle audio is the audio output by the vehicle navigation, and the sound field is located in a certain range near the driver position, the driver is determined as the user for gaze tracking, and the gaze tracking-based sound effect adjustment service is provided for the driver, for example, the volume of the vehicle navigation is increased through sound effect adjustment. If the sound field of the audio output by the vehicle audio is located in a certain range near the rear passenger position, for example, the audio output by the vehicle audio is the audio output by the rear entertainment screen, and the sound field is located in a certain range near the rear passenger position, the rear passengers are determined as the user for gaze tracking, and the gaze tracking-based sound effect adjustment service is provided for the rear passengers, for example, the volume of the rear entertainment screen is increased through sound effect adjustment.

[0062] Further, in an embodiment, referring to Figure 3 , Figure 3 the detailed flowchart of step S30 in this application Figure 1 , as shown in the figure, step S30 includes: Figure 3

[0063] Step S301, according to the gaze direction of the user and the layout in the vehicle, the object gazed by the user is determined.

[0064] Step S302, according to the object gazed by the user, a preset mapping table is searched to determine the target sound effect parameter, the preset mapping table includes the corresponding relationship between the object gazed by the user and the target sound effect parameter.

[0065] ​In this embodiment, the in-vehicle layout, i.e., the positions of various objects in the vehicle such as the front central control screen, the rear entertainment screen, the windows, and the like in the vehicle, can be determined according to the line-of-sight direction of the user in combination with the in-vehicle layout, so as to determine the object gazed at by the user. The target sound effect parameter can be obtained by searching a preset mapping table according to the object gazed at by the user. For example, the object gazed at by the user is the front central control screen, and the target sound effect parameter corresponding to the object gazed at by the user is obtained by searching the mapping table. The preset mapping table can be customized in advance. For example, the driver or passenger can set the target sound effect parameter corresponding to the object gazed at by the user according to the demand of the user through a terminal, so that the sound effect adjustment based on the line-of-sight tracking has high personalization.

[0066] Further, in an embodiment, the vehicle sound effect adjustment method further includes:

[0067] When it is detected that the line-of-sight of the multiple users is mutual and the conversation voice is recognized through the microphone, it is determined that the multiple users in mutual gaze are in conversation, and the volume of the loudspeaker in a third preset range of the position of the multiple users in mutual gaze is reduced.

[0068] When it is detected that the user is using the mobile phone and the mobile phone is playing sound is recognized through the microphone, it is determined that the user is using the mobile phone audio, and the volume of the loudspeaker in a fourth preset range of the position of the user is reduced.

[0069] When it is detected that the user is closing eyes and the duration of closing eyes exceeds a preset duration, it is determined that the user is in a rest state, and the volume of the loudspeaker in a fifth preset range of the position of the user is reduced.

[0070] In this embodiment, the line-of-sight direction of the multiple users is tracked or analyzed based on video images, it is detected that the line-of-sight of the multiple users is mutual, and the conversation voice is recognized through the vehicle microphone, so it is determined that the multiple users in mutual gaze are in conversation. At this time, the volume of the loudspeaker in a certain range near the position of the multiple users in mutual gaze can be reduced, so that the conversation of the driver or passenger is more smooth. The line-of-sight of the user is tracked or analyzed based on video images, it is detected that the user is using the mobile phone, and the mobile phone is playing sound is recognized through the vehicle microphone, so it is determined that the user is using the mobile phone audio. At this time, the volume of the loudspeaker in a certain range of the position of the user can be reduced to improve the experience of the user when using the mobile phone audio. The line-of-sight of the user is tracked or analyzed based on video images, it is detected that the user is closing eyes and the duration of closing eyes exceeds a preset duration, for example, it is detected that the line-of-sight of the user is lost for more than a certain duration, so it is determined that the user is in a rest state. At this time, the volume of the loudspeaker in a certain range of the position of the user can be reduced to provide a good rest environment for the user.

[0071] Further, in an embodiment, the vehicle sound effect adjustment method further includes:

[0072] When it is detected that the in-vehicle game is started and the user's line-of-sight direction is the in-vehicle game, the volume corresponding to the character or object in the game to which the user's line-of-sight focuses is increased.

[0073] In the embodiment, when it is detected that the in-vehicle game is started and the user's line-of-sight direction is the in-vehicle game, it is judged that the user is in the game scene, and the volume corresponding to the character or object in the game to which the user's line-of-sight focuses is increased, so as to provide the user with a more immersive sound effect experience through the sound effect adjustment algorithm based on line-of-sight tracking.

[0074] Further, in an embodiment, the vehicle sound effect adjustment method further includes:

[0075] According to the tracked user line-of-sight direction data, the user's behavior is predicted through a machine model;

[0076] According to the predicted user behavior, the sound effect parameters of the vehicle audio are adjusted.

[0077] In the 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, and the type and structure of the specific machine model are not limited herein. According to the predicted user's next behavior, the sound effect parameters of the vehicle audio are adjusted, so that the sound effect adjustment based on line-of-sight has a forward-looking nature and can provide the user with sound effect adjustment service based on line-of-sight in advance. For example, the machine model identifies that the user will take a nap every certain period of time based on the input continuously tracked user line-of-sight direction data, and predicts that the user will fall asleep soon. Then, the machine model can intervene in advance to turn off the sound field within a certain range of the user's position as early as possible, so as to make the user enter the rest state as early as possible.
