In this embodiment, the sound effect control method 100 may include the following steps S110 to S130
Step S110: ear position information of a human ear is acquired.
In this embodiment, the camera may be controlled to acquire an image of a user seated in the vehicle, and then the position of the human ear in the image is identified from the facial image through image processing methods such as edge detection and feature extraction; or inputting the image as data of an ear recognition model, wherein the output of the ear recognition model is the position of the ear in the face image, and the ear recognition model is a deep neural network obtained by training a large number of face images marked with the ear.
Further, since the position of the user in the vehicle is relatively fixed, when the placement position of the camera in the vehicle is known, the relative position of the camera and the human ear can be calculated according to the position of the human ear in the image, that is, the position of the human ear in the vehicle can be determined.
Since the position of the speakers in the car is also known, the relative distance and angle between the human ear and the speakers can be further determined.
In some embodiments, the image may also include a speaker image, and by identifying the human ear and the speaker in the image, the relative distance and angle between the human ear and the speaker can be accurately calculated.
Step S120: and if the position information of the human ear is changed, acquiring the human ear movement information of the human ear.
When the body or the head of the user moves, the position of the human ear correspondingly changes. In this embodiment, the camera may be controlled to acquire the image of the user in the vehicle in real time, and when the position information of the human ear changes, the movement information of the human ear before and after the movement of the human ear is acquired. Specifically, when the ear position information of the human ear is changed, the moving distance between the human ear and the speaker and the deflection angle between the human ear and the speaker can be calculated.
Step S130: and adjusting the audio parameters according to the human ear movement information so that the current audio effect of the current audio received by the human ear is the same as the preset audio effect.
When the audio parameters of the audio frequency are kept unchanged, if the positions of the human ears are different, the sound effect heard by the user is different. In this embodiment, when the position of the human ear changes, the audio parameter of the current audio frequency may be adjusted according to the moving distance between the human ear and the speaker and the deflection angle between the human ear and the speaker, and the adjustment degree of the audio parameter is based on that the current audio frequency of the current audio frequency received by the human ear of the user at the current position is the same as the preset audio frequency.
Specifically, when a user of standard height is in a fixed position in a standard sitting position, the ear of the user can receive a preset sound effect of the current audio, wherein the preset sound effect can be a sound effect which is adjusted in advance to achieve the best hearing enjoyment. It can also be understood that, when the distance and the angle between the ear of the user and the speaker are the preset distance and the preset angle, the current audio effect of the current audio played from the speaker by the preset audio parameter received by the ear is the preset audio effect. In this embodiment, when the people's ear removed, distance and angle between people's ear and the speaker all changed, can be according to the migration distance and the deflection angle between people's ear and the speaker this moment, calculate the required audio parameter when the current audio of the current audio that plays from the speaker reaches the preset audio, adjust the audio parameter of current audio in real time according to the calculated result again, and then can be at the in-process that the people's ear removed, make the current audio that the people's ear received the current audio of playing from the speaker keep being preset audio, thereby make the head of user remove anyhow and all can make the user continuously enjoy sound field and audio that the timing is good.
According to the sound effect control method provided by the embodiment of the application, the human ear position information of the human ear is acquired, if the human ear position information changes, the human ear movement information of the human ear is acquired, and the audio parameter is adjusted according to the human ear movement information, so that the current sound effect of the current audio received by the human ear is the same as the preset sound effect, the audio parameter is adjusted when the head of a user moves, and the user can enjoy the sound field and sound effect which are well adjusted no matter how the head of the user moves.

In this embodiment, the sound effect control method 200 may include the following steps S210 to S290.
Step S210: and acquiring the identity information of the user.
When the users in the vehicle are multiple, the identity information of each user can be obtained. In this embodiment, the camera may be controlled to obtain facial images of each user in the vehicle, and the facial images of each user may be subjected to face recognition, so as to obtain the identity of each user.
In some embodiments, the camera may be controlled to obtain an image of the inside of the vehicle, and identify the location of each user in the vehicle, thereby obtaining the identity of each user in the vehicle. It should be noted that, in this embodiment, the identity information of the user refers to the identity of the user in the vehicle, for example, if it is recognized that the user a is located in the driver seat, the identity of the user a in the vehicle is the driver; and if the user B is identified to be positioned in the rear seat, the identity of the user B in the vehicle is a passenger.
Step S220: and judging whether the identity information accords with the target identity information.
In this embodiment, the target identity information may be a specific person. For example, the target identity information may be the identity information of the vehicle owner, and when the identity information of the user and the identity information of the vehicle owner are obtained through face recognition, the following step S230 may be continuously performed to determine that the user is the target user and obtain the user location information of the target user in the vehicle. When the obtained identity information of the user does not conform to the identity information of the vehicle owner through the face recognition, the step S210 may be executed again to obtain the identity information of the user.
In some embodiments, the target identity information may be a person located at a particular seat. For example, the target identity information may be a driver, and when the identity information of the user is the driver, the following step S230 may be continuously performed to determine that the user is the target user and acquire the user location information of the target user in the vehicle. When the identity information of the user is not the driver, the process may return to step S210 to obtain the identity information of the user again. It should be noted that the destination identification information may be not limited to the driver, but may be a passenger in the passenger seat, or a passenger in the rear seat.
Step S230: and judging that the user is the target user, and acquiring the user position information of the target user in the vehicle.
In this embodiment, when the identity information of the user conforms to the target identity information, it is determined that the user is a target user, and the user location information of the target user in the vehicle is acquired. For example, when the user is the owner of the vehicle, the position information of the owner of the vehicle in the vehicle may be acquired. Specifically, the camera can be controlled to acquire images in the vehicle and identify the position of the vehicle owner in the vehicle. The position of the vehicle owner in the vehicle can be located in a driver seat, a passenger seat, a rear seat and the like.
Step S240: and calling a preset audio parameter corresponding to the current position of the user according to the user position information, and playing the current audio according to the preset audio parameter.
The vehicle-mounted audio can be played by a loudspeaker system in a vehicle, in the embodiment of the application, the loudspeaker system can comprise at least two paths of loudspeakers, the at least two paths of loudspeakers can be arranged around a vehicle seat to form at least two sound channels, and the at least two sound channels can comprise six directions of front, back, left, right, upper, lower and the like which take the vehicle seat as the center; as an alternative embodiment, the speakers may be arranged at the following positions, respectively: the door, the front center console, the ceiling, the rear storage plate, the floor and the seat of the automobile; in particular, the speakers on the seat may be arranged at the seat headrest. By arranging the speakers capable of rotating in various directions centering on the seat, after a user sits on the seat, a three-dimensional sound field can be generated by the plurality of speakers arranged around the user, particularly, the speakers arranged on the ceiling and the floor, and a sound field effect that a sound source is positioned at the top and under the feet of the user can be created. The loudspeaker position layout disclosed in this embodiment can create a stereo sound field for a user, and in the stereo sound field, the user can feel a sound effect of 360-degree surround compared with a two-dimensional planar sound field, which is more real and natural.
In the embodiment of the present application, the audio parameter may include at least one of the following parameters: the amplitude of the audio, the frequency response range of the audio, the phase between the channels, and the time difference between the channels.
Furthermore, each seat in the vehicle can be set with a preset audio parameter, and when the audio is played by the preset audio parameter, a user on the fixed seat corresponding to the preset audio parameter can receive the audio by a preset sound effect, namely the user can enjoy the adjusted optimal sound field and sound effect. For example, a preset audio parameter a may be set for the primary driver seat, and a preset audio parameter B may be set for the secondary driver seat, and when playing audio with the preset audio parameter a, the user in the primary driver seat may receive the audio with a preset sound effect, and when playing audio with the preset audio parameter B, the user in the secondary driver seat may also receive the audio with a preset sound effect.
In this embodiment, the preset audio parameter corresponding to the current position of the target user may be called according to the user position information of the target user, and the current audio is played according to the preset audio parameter. For example, when the audio starts to be played, if the owner is located at the main driver seat, a preset audio parameter corresponding to the main driver seat may be called, and the current audio is played according to the preset audio parameter; when the audio starts to be played, if the vehicle owner is located in the passenger seat, a preset audio parameter corresponding to the passenger seat can be called, and the current audio is played according to the preset audio parameter; when the audio starts to be played, if the car owner is located at the back seat, the preset audio parameter corresponding to the back seat can be called, and the audio is played according to the preset audio parameter.
Step S250: and acquiring image information of the target user.
In this embodiment, in the audio playing process, the camera may be controlled to obtain the image information of the target user in real time.
Step S260: and determining distance information and angle information according to the image information.
In this embodiment, the ear position information of the target user may be obtained according to the image information of the target user. In this embodiment, the ear position information of the target user includes distance information between the ears of the target user and the speakers and angle information between the ears of the target user and the speakers.
Further, the position of the human ear in the image can be identified from the face image in the image information of the target user through image processing methods such as edge detection, feature extraction and the like; or inputting the image as data of an ear recognition model, wherein the output of the ear recognition model is the position of the ear in the face image, and the ear recognition model is a deep neural network obtained by training a large number of face images marked with the ear. Because the position of the user in the vehicle is relatively fixed, under the condition that the placement position of the camera in the vehicle is known, the relative position of the camera and the human ear can be calculated according to the position of the human ear in the image, and the position of the human ear in the vehicle can be determined. And since the positions of the speakers in the vehicle are also known, it is possible to further determine distance information and angle information between the human ear of the target user and the respective speakers.
In some embodiments, the image information of the target user may also include an image of a speaker, and by identifying the human ear and the speaker in the image, distance information and angle information between the human ear and each speaker may be accurately calculated.
Step S270: and judging whether the position information of the human ear changes.
Because the target user hardly keeps the standard sitting posture in the driving process of the vehicle, when the body or the head of the target user moves, the positions of the ears of the user can be correspondingly changed, namely, the distances and the angles between the ears of the target user and the speakers can be changed, so that the current sound effect of the current audio received by the target user is changed, the current audio cannot be received by the preset sound effect, and the current audio cannot be enjoyed by the adjusted sound field and sound effect.
In this embodiment, when the image information of the target user is obtained, it may be determined whether the position information of the ears of the target user changes, that is, whether the distances and angles between the ears of the target user and the speakers change. If the change occurs, it indicates that the sitting posture of the target user has changed, and in this case, the following step S280 may be performed to determine the movement distance information and the deflection angle information according to the image information. If the sitting posture of the target user is not changed, the process returns to step S250 to obtain the image information of the target user again.
Step S280: and determining the moving distance information and the deflection angle information according to the image information.
In this embodiment, if the position information of the ears of the target user changes, the ear movement information of the ears of the target user may be obtained according to the image information of the target user. In this embodiment, the ear movement information of the target user's ear may include movement distance information between the target user's ear and each speaker and deflection angle information between the target user's ear and the speaker.
Specifically, if the distance and angle between the ear of the target user and each speaker are changed, the moving distance and the deflection angle between the ear of the target user and each speaker are calculated according to the image information of the target user.
Step S290: and adjusting the audio parameters according to the human ear movement information so that the current audio effect of the current audio received by the human ear is the same as the preset audio effect.
In the audio playing process, when the audio parameters of the current audio are kept unchanged, if the positions of the ears of the target user are different, the sound effects of the current audio received by the target user are also different. In this embodiment, if the position of the ear of the target user is changed, the audio parameter of the current audio frequency may be adjusted according to the ear movement information of the target user, and the adjustment degree of the audio parameter is based on the fact that the current audio frequency received by the ear of the target user at the current position is the same as the preset audio frequency.
Specifically, when the target user is located at a fixed position in a standard sitting position, the human ear of the target user can receive a preset sound effect of the current audio, wherein the preset sound effect can be a sound effect which is adjusted in advance to achieve the best hearing enjoyment. It can also be understood that, when the distance and the angle between the ear of the target user and each speaker are the preset distance and the preset angle, the current audio effect of the current audio played from the speaker by the preset audio parameter received by the ear of the target user is the preset audio effect. In this embodiment, when the position of the human ear of the target user changes, the distance and the angle between the human ear of the target user and each speaker all change, at this moment, the audio parameters required when the current audio of the current audio played from the speakers reaches the preset audio can be calculated according to the moving distance and the deflection angle between the human ear of the target user and each speaker, and then the audio parameters of the current audio are adjusted in real time according to the calculation result, so that in the process of moving the human ear of the target user, the current audio of the current audio played from the speakers is kept as the preset audio by the human ear of the target user, and therefore the target user can continuously enjoy the adjusted sound field and audio no matter how the body and the head of the target user move.
It should be noted that the preset sound effect is the current sound effect of the current audio received by the ear of the user with the standard height at the fixed position in the standard sitting position, that is, the preset sound effect is the current sound effect of the current audio received by the ear of the user at the preset position. Therefore, when the audio starts to be played, the distance difference and the angle difference between the current position and the preset position of the ear of the target user can be calculated by acquiring the position of the ear of the target user, and then the audio parameters of the current audio are correspondingly adjusted according to the distance difference and the angle, so that the current audio effect of the current audio received by the ear of the target user is the same as the preset audio effect, and therefore, when the audio starts to be played, the preset audio effect of the current audio can be received without a standard sitting posture even if the target user is not of a standard height, and the adjusted sound field and audio effect can be enjoyed.
The sound effect control method provided by the embodiment of the application comprises the steps of obtaining identity information of a user, judging whether the identity information accords with target identity information, if the identity information accords with the target identity information, judging that the user is a target user, obtaining user position information of the target user in a vehicle, calling a preset audio parameter corresponding to the current position of the user according to the user position information, playing current audio according to the preset audio parameter, obtaining image information of the target user, determining distance information and angle information according to the image information, judging whether the position information of a human ear changes, if the position information of the human ear changes, determining moving distance information and deflection angle information according to the image information, and finally adjusting the audio parameter according to the moving information of the human ear to enable the current sound effect of the current sound to be the same as the preset sound effect, so that the target user can continuously enjoy adjusted sound effect no matter how the body and the head of the target user move Sound field and sound effects.
