Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of audio processing, and in particular, to an audio adjustment method, apparatus, display device, and storage medium. Background Art

[0002] When we watch TV, the objects on the screen are usually moving and their positions are changing. For example, a flying bird may be located in the lower left corner of the screen at the moment, and may fly to the upper right corner of the screen the next moment. However, the positions of the speakers configured for the TV remain unchanged, so the position of the composite sound and image produced by each speaker remains unchanged. For example, if the speakers are installed symmetrically on the left and right sides under the TV, the sound and image are always in the middle of the TV. This results in the sound and image positions being inconsistent with the positions of the objects in the picture, which is different from the feeling in real life, and brings a relatively poor viewing experience to users.

[0003] In order to make the sound and picture consistent, some methods for achieving sound and picture tracking have been proposed in the prior art. By controlling the amplitude and phase information of each speaker, the synthetic sound and image position and the real-time position of the moving object are overlapped to achieve sound and picture tracking. However, the prior art mainly focuses on assuming that the audience is in the middle position in front of the TV. The center of the screen is also used as the origin in the algorithm, and then the sound and image position is overlapped with the real-time position of the moving object in the picture, so that the user sitting in the middle position in front of the TV can enjoy the sound effect of sound and picture tracking. However, in actual use, the user may deviate from the center position. For example, if the user sits near the speaker position on the left side of the TV, if the moving object in the current picture is on the right side of the screen, the amplitude of the right speaker will be increased in the sound and picture tracking algorithm, but this increase is based on the premise that the user is in the middle position. When the audience sits near the speaker position on the left side of the TV, this increase may not produce the sound and image on the right side. Since the user hears mainly the sound from the left speaker at this time, the user may still feel that the sound and image are on the left after the algorithm is adjusted. At this time, the problem of poor sound and picture tracking effect due to the deviation of the user position will occur. Therefore, the poor sound and picture tracking effect caused by the deviation of the user's viewing position from the center has become a problem that needs to be solved urgently.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] To facilitate understanding of the embodiments of the present invention, specific embodiments will be further explained below in conjunction with the accompanying drawings. The embodiments do not constitute a limitation on the embodiments of the present invention.

[0055] Figure 1 A flowchart of an audio adjustment method provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the method specifically includes:

[0056] S11. Obtain position parameters of a target object in a preset area in front of a screen of a display device.

[0057] The audio adjustment method provided in the embodiment of the present invention is applied to a display device, which may include but is not limited to: a smart TV, a projector, a desktop computer, etc. The display device has two audio devices (for example, speakers, loudspeakers, stereos, etc.), which are respectively arranged at the left and right ends of the display device, and are used to achieve an audio and video tracking effect when the display device plays a video. Specifically, the audio device of the display device can be adjusted according to the position parameters and offset state of the target object in front of the display device screen, so that the audio played by the display device can be accurately associated with the position of the target object in front of the display device screen.

[0058] In this embodiment, an area range suitable for viewing in front of the display device screen is pre-set as a preset area, and the target object is a user viewing the display device. When it is detected that the target user enters the preset area and remains in the same position, the position parameters of the current position of the target object relative to the display device are obtained. The position parameters can represent the offset angle, offset direction and distance of the target position of the target object relative to the center point of the display device screen.

[0059] Specifically, obtaining the position parameters of the target object in a preset area in front of the screen of the display device includes:

[0060] When the display device is turned on and it is detected that the time length of time that the target object is in the preset area is greater than the preset time length, a first distance from the target position of the target object to the center position of the display device is obtained, and a second distance from the target position vertically to the display device is obtained; a first offset angle of the target position relative to the vertical central axis plane of the display device is obtained, and a second offset angle of the target position relative to the horizontal central axis plane of the display device is obtained; the first distance, the second distance, the first offset angle and the second offset angle are used as position parameters.

[0061] In this embodiment, when the target object is in the preset area for a time longer than a preset time and the position does not change, the middle position of the line connecting the two ears of the target object is obtained as the target position. The first distance and the first offset angle are used to determine the adjustment strategy when the target object is horizontally offset relative to the center position of the display device, and the second distance and the second offset angle are used to determine the adjustment strategy when the target object is vertically offset relative to the center position of the display device. The center position can represent the best viewing position of the user in front of the display device screen, which can make the user's viewing angle and the center of the display device screen at the same horizontal height (for example, it can be the center of the screen, and the center position can also be set according to the height of the sofa or chair in front of the screen).

[0062] Specifically, the shortest distance from the target position to the vertical center axis of the display device can be obtained as the first distance through a camera or a distance sensor, wherein if the target object is not offset in the vertical direction, the first distance is the distance from the target position to the center position of the display device screen. The angle between the line connecting the target position to the vertical center axis and the plane formed by the vertical center axis perpendicular to the screen is obtained as the first offset angle.

[0063] The shortest distance from the target position to the plane where the screen is located is obtained through a camera or a distance sensor as the second distance, and the angle between the line from the target position to the horizontal central axis of the screen and the plane formed by the horizontal central axis perpendicular to the screen is obtained as the second offset angle.

[0064] S12. Determine an offset state of the target object according to the position parameter.

[0065] In this embodiment, the offset state characterizes the offset direction of the target object, which may include: horizontal offset and vertical offset, wherein the horizontal offset also includes: horizontal left offset and horizontal right offset, the left and right offsets are used to determine the specific audio device whose audio parameters need to be adjusted, and the vertical offset also includes: vertical upward offset and vertical downward offset, and the up and down offsets are used to determine the direction of rotation required to adjust the angle of the audio device.

[0066] S13: Determine an adjustment strategy for the audio device of the display device according to the position parameter and the offset state.

[0067] In this embodiment, when the offset state is a horizontal offset, a compensation value of the audio parameter is calculated based on the first distance and the first offset angle. The compensation value is used to compensate for the delay and sound intensity of the audio device. The compensation method may be to add or multiply the compensation value on the basis of the initial audio parameter. The specific adjustment strategy may include: when the target object is horizontally offset to the left, the audio parameters of the audio device on the left need to be compensated according to the compensation value; when the target object is horizontally offset to the right, the audio parameters of the audio device on the right need to be compensated according to the compensation value.

[0068] When the offset state is vertical offset, the target angle to which the audio device angle needs to be adjusted is calculated based on the second distance and the second offset angle. The target angle is used to adjust the initial audio device angle. The specific adjustment strategies may include: when the target object is offset horizontally upward, the audio device angles of the two audio devices need to be rotated upward by the target angle; when the target object is offset horizontally downward, the audio device angles of the two audio devices need to be rotated downward by the target angle.

[0069] S14: Adjust the audio parameters and / or the audio device angle of the audio device according to the adjustment strategy.

[0070] In this embodiment, when only a horizontal offset exists, the initial audio parameters of the determined target audio device can be adjusted according to the adjustment strategy, and when only a vertical offset exists, the initial angles of the two determined audio devices can be adjusted according to the adjustment strategy. When the target object has both a horizontal offset and a vertical offset, the audio parameters and the audio device angle can be adjusted at the same time.

[0071] The audio adjustment method provided by the embodiment of the present invention obtains the position parameters of the target object in the preset area in front of the display device screen; determines the offset state of the target object according to the position parameters; determines the adjustment strategy of the audio device of the display device according to the position parameters and the offset state; and adjusts the audio parameters and / or the audio device angle of the audio device according to the adjustment strategy. Thus, the audio device of the display device can be adjusted according to the position parameters and the offset state of the target object in front of the display device screen, so that the audio can be accurately associated with the position of the target object, thereby achieving a better audio and video tracking effect for any viewing position of the user, solving the problem of poor audio and video tracking effect caused by the user's viewing position deviating from the middle in the prior art.

[0072] Figure 2 A flowchart of another audio adjustment method provided by an embodiment of the present invention is shown as follows: Figure 2 As shown, the method specifically includes:

[0073] S21. Obtain position parameters of a target object in a preset area in front of a screen of a display device.

[0074] In this embodiment, similar to step S11, the specific Figure 1 For the sake of brevity, the relevant content will not be elaborated here.

[0075] S22: When the first offset angle is a non-zero value, determine that the offset state is a horizontal offset; when the second offset angle is a non-zero value, determine that the offset state is a vertical offset.

[0076] In this embodiment, it is determined whether the first offset angle and the second offset angle are zero. When the first offset angle is a non-zero value, the offset state is determined to be a horizontal offset, and steps S23 and S24 are executed. When the second offset angle is a non-zero value, the offset state is determined to be a vertical offset, and step S25 is executed. The horizontal offset and the vertical offset may exist separately or simultaneously. When they exist simultaneously, steps S23, S24 and S25 may be executed simultaneously, or steps S23 and S24 may be executed first, and then S25 may be executed.

[0077] S23, when the offset state is a horizontal offset, determining a sound intensity compensation value and a delay compensation value of the audio device according to the first offset angle, the first distance, and a third distance between two audio devices of the display device;

[0078] S24. Determine the adjustment strategy as follows: determine a target audio device according to a direction of a horizontal offset of the target object, and adjust audio parameters of the target audio device according to the sound intensity compensation value and the delay compensation value, wherein the audio parameters include: sound intensity and delay of the audio device.

[0079] In this embodiment, the third distance between the two audio devices is obtained, and the delay compensation value is calculated by the following formula:

[0080] First, the distance difference between the two audio devices and the target location is determined by the following formula:

[0081]

[0082] Wherein, E is the distance difference, x is the first distance, θ is the first offset angle, and B is the third distance;

[0083] Further

[0084]

[0085] Wherein, ΔT is the delay compensation value.

[0086] The sound intensity compensation value is calculated by the following formula:

[0087]

[0088] Wherein, ΔP is the sound intensity compensation value.

[0089] Furthermore, the current horizontal offset direction of the target object is determined. When it is offset to the left, that is, when the target object is on the left side of the vertical central axis of the screen, the audio device on the left side of the display device corresponding to the target object's position is determined as the target audio device. When it is offset to the right, that is, when the target object is on the right side of the vertical central axis of the screen, the audio device on the right side of the display device corresponding to the target object's position is determined as the target audio device, that is, the audio device closer to the target object is determined as the target audio device.

[0090] Since the display device will generate different sound intensities and delays for each audio device when the sound-emitting object is at different positions on the screen according to the existing audio and video tracking technology, in order to meet the audio and video tracking effect when the user is in the center position in front of the screen, the target audio device will have an initial delay and initial sound intensity. The delay compensation value is superimposed on the initial delay, and the sound intensity compensation value is superimposed on the initial sound intensity, and then the audio output is performed to achieve the adjustment of the audio parameters.

[0091] As an example, Figure 5The figure shows a schematic diagram of an application scenario provided by an embodiment of the present invention, including two audio devices and a target object. At this time, the target object moves horizontally to the left, B is the third distance between the two audio devices, x is the first distance, θ is the first offset angle, and the horizontal displacement of the target object is d. Optionally, the straight-line distance n of the target object close to one side of the sound source and f on the other side can also be obtained. The second distance of the target object perpendicular to the plane where the screen is located is L, and n, f, and L can be used to assist in calculating θ and x.

[0092] As another example, Figure 6 The figure shows another application scenario provided by an embodiment of the present invention. The target object is horizontally offset to the right as an example. The display device is a TV. The current aircraft is located in the lower left corner of the TV screen. The audio device includes a left speaker and a right speaker. First, the TV generates the initial sound intensity and initial delay of the speaker in the audio and video tracking algorithm without considering the user position offset, as shown in the following table:

[0093] Left channel speaker Right channel speaker Sound intensity P 0.2P Delay 0 0.5T

[0094] The sound intensity in the table is the relative value of the sound intensity of each speaker, not the absolute sound intensity value. T is a time value selected according to actual debugging. According to the initial parameters in the above table, if the user is in the middle position, the synthetic sound image position will coincide with the aircraft position, but at this time the user is to the right, and the sound intensity of the right speaker is stronger, causing the synthetic sound image position to shift to the right and no longer coincide with the aircraft position, so the sound and picture tracking effect will become very poor.

[0095] Therefore, according to the adjustment strategy of this embodiment, the target audio device is determined to be the right speaker, and the initial sound intensity and initial delay of the right speaker are compensated, and the following table after compensation is obtained:

[0096] Left channel speaker Right channel speaker Sound intensity P 0.2P+ΔP Delay 0 0.5T+ΔT

[0097] By taking into account the sound intensity and delay difference caused by the user's position offset, and superimposing this difference when distributing the audio signal input to the speaker, it can be achieved that the synthetic sound and image position at this time still remains consistent with the aircraft position, achieving better audio and video tracking effects.

[0098] S25. When the offset state is a vertical offset, determine a target angle for the vertical rotation of the two audio devices according to the second offset angle and the second distance; determine the adjustment strategy as follows: determine the vertical offset direction of the target object, and adjust the angle of the audio device according to the vertical offset direction and the target angle.

[0099] In this embodiment, the offset distance of the target position of the target object in the vertical direction can be determined according to the second distance and the second offset angle, and the target angle can be determined by the following formula:

[0100] Wherein, α is the target angle, y is the offset distance, and z is the second distance (that is, the horizontal distance from the target position to the plane where the screen is located).

[0101] When the target position is above the horizontal plane of the center position, the vertical offset direction is determined to be an upward offset. At this time, the adjustment strategy is to rotate the audio device angles of the two audio devices upward by the target angle. When the target position is below the horizontal plane of the center position, the vertical offset direction is determined to be a downward offset. At this time, the adjustment strategy is to rotate the audio device angles of the two audio devices downward by the target angle.

[0102] In a possible implementation, when the second offset angle is less than the preset angle value and the first offset angle is a non-zero value, the audio parameters of the audio device are adjusted only according to the adjustment strategy, that is, when the vertical offset angle is small, it can be ignored, and only the audio parameters corresponding to the horizontal offset are adjusted.

[0103] When the first offset angle and the second offset angle are both non-zero values, the audio parameters of the audio device are first adjusted according to the adjustment strategy, and then the audio device angle of the audio device is adjusted according to the adjustment strategy, so as to reduce the processing pressure of the display device and increase the processing efficiency.

[0104] As an example, Figure 7 FIG. 1 is a schematic diagram of another application scenario provided by an embodiment of the present invention. Figure 8 The figure shows another application scenario schematic diagram provided by an embodiment of the present invention. Due to different heights of users, different postures of users watching TV, different installation heights of TV, etc., there may be inconsistency between the height direction of the user's ear and the center of the screen. At this time, the audio in the vertical direction is adjusted. Figure 7 is the initial position of the speaker's sound-emitting surface (it can also be the horizontal plane where the center position is located). The plane wave generated by the speaker vibration propagates forward parallel to the speaker's sound-emitting surface, and the synthetic sound image position of the two speakers is also at the same height as the speakers. Figure 8 When the target position is shifted upward, the speaker is rotated upward according to the target angle, and the synthetic sound image position height of the sound wave propagation is compared Figure 7 There will be an improvement. In order to use the rotation of the speaker to correct the deviation of the user's position in the height direction relative to the center of the screen.

[0105] S26. Adjust the audio parameters and / or the audio device angle of the audio device according to the adjustment strategy.

[0106] In this embodiment, similar to step S14, the details can be referred to Figure 1 For the sake of brevity, the relevant content will not be elaborated here.

[0107] The audio adjustment method provided in the embodiment of the present invention can adjust the audio device of the display device according to the position parameters and offset status of the target object in front of the display device screen. When the user offsets horizontally, the target audio device is determined to compensate for the audio parameters. When the user offsets vertically, the rotation angle of all audio devices is adjusted. When horizontal offset and vertical offset exist at the same time, they can be adjusted simultaneously, thereby achieving a better audio and video tracking effect for any viewing position of the user, solving the problem of poor audio and video tracking effect caused by the user's viewing position deviating from the middle in the prior art, and ensuring the accuracy and personalized adjustment of audio and video tracking.
