Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

Fig. 1 is a flowchart of a speaker angle adjustment method of a vehicle according to one embodiment of the present invention.

Wherein the vehicle comprises a plurality of loudspeakers arranged in the vehicle, for example: four loudspeakers arranged at the left front, the left rear, the right front and the right rear in the vehicle.

As shown in fig. 1, a speaker angle adjusting method of a vehicle according to an embodiment of the present invention includes the steps of:

s101: the method comprises the steps of collecting images of people in the vehicle and/or collecting audio signals of the people in the vehicle.

Specifically, images of persons in the vehicle can be acquired through a 360-degree rotary camera arranged in the vehicle. The audio signal may be collected by a plurality of microphones, for example, 4, provided in the vehicle at the front left, rear left, front right, and rear right in the vehicle.

S102: and identifying the position of the human ear according to the image of the person in the vehicle and/or judging the position of the human ear according to the audio signal of the person in the vehicle.

Specifically, the method for identifying the position of the human ear according to the image of the person in the vehicle comprises the following steps: according to the images of the persons in the vehicle, the distribution of the persons in the vehicle and the spatial position of the ear of each person in the vehicle are identified. For example: the human face position is identified according to the image of personnel in the vehicle, the human ear position is determined according to the human face position, and after the human face position is determined, the human ear position can be roughly determined according to the human face position.

The position of the human ear is judged according to the audio signal of the personnel in the vehicle, and the method comprises the following steps: according to the delay time of the audio signal collected by the microphone, the position of the mouth of the passenger is judged, and then the position of the ear of the passenger is determined, wherein the position of the ear of the passenger is generally positioned about 5 centimeters above the mouth. For example: and determining the mouth position of the person in the vehicle according to the delay time of the audio signals collected by the plurality of microphones and the positions of the plurality of microphones, and determining the ear position according to the mouth position.

As shown in fig. 4 and with reference to fig. 5, four microphones are placed at the ceiling positions of four seats in the vehicle, when a person in the vehicle speaks to make a sound, the microphones installed at various positions in the vehicle can collect the audio signals made by the person in the vehicle, because the placing positions of the microphones are fixed and different, the distance from the person in the vehicle to each microphone is different, the time for collecting the audio signals by each microphone is also different, and because the propagation speed of the sound in the air is known as a constant V, according to the formula:

D＝V*(S1-S2)，

the difference of the distances from the vehicle interior personnel to different microphones can be calculated, wherein S1 and S2 are the time taken by the different microphones to acquire the audio signals of the vehicle interior personnel, the specific position of the mouth of the vehicle interior personnel in the vehicle can be obtained according to the difference, and the position of the ear of the vehicle interior personnel in the vehicle can be deduced because the ear of the vehicle interior personnel is generally positioned at the position of 5cm above the mouth.

S103: and obtaining the angles of the sound production directions of the plurality of loudspeakers pointing to the positions of the human ears according to the positions of the human ears and the positions of the plurality of loudspeakers.

Specifically, assuming that the left-right direction of the vehicle is the X-axis of the three-dimensional coordinate system, the front-back direction of the vehicle is the Y-axis of the three-dimensional coordinate system, and the up-down direction of the vehicle is the Z-axis of the three-dimensional coordinate system, the coordinates of the position of the human ear are determined with each of the plurality of speakers as the origin, respectively, and the angle at which the sound emission direction of each of the plurality of speakers points at the position of the human ear is obtained from the coordinates of the position of the human ear, respectively.

As a specific example, a horizontal plane on which a tweeter (i.e., a speaker according to an embodiment of the present invention) is located is set as a reference plane, the vehicle left-right direction is an X-axis, the vehicle front-rear direction is a Y-axis, and the vehicle up-down direction is a Z-axis.

After the specific distribution position of the vehicle interior person is identified from the image of the vehicle interior person, any tweeter position to be directed to a specific position is taken as the origin of coordinates.

As shown in fig. 2, after the specific positions of the ears of the passengers are identified, the coordinates of the ear of each passenger are fixed, and the coordinates of the ear of the person on which the tweeter is to be rotationally directed are set to (X1, Y1, Z1) as being known.

As shown in fig. 3, assuming that the angle at which the tweeter faces the vehicle interior is 0 °, the angle of the human ear relative to the tweeter in the XY plane is obtained as B ═ arctan (Y1/X1).

The angle of the tweeter in the XY plane before adjustment is set to be A DEG, and the angle of the tweeter required to rotate in the XY plane is set to be (B-A) °.

From the pythagorean theorem, it is known that the horizontal distance from the ear to the treble on the XY plane is √ (X2+ Y2), and as shown in fig. 3, the angle of the ear in the vertical direction with respect to the horizontal plane is D ═ arctan [ Y1/√ (X2+ Y2) ].

If the angle of the tweeter in the Z direction before adjustment is D °, the tweeter needs to be rotated by (C-D) degrees in the Z direction.

S104: and adjusting the directions of the plurality of loudspeakers according to the angle so that the sound production directions of the plurality of loudspeakers are directed to the positions of human ears. For example: controlling the loudspeaker to rotate by (B-A) degree in the XY plane and by (C-D) degree in the Z direction

In a specific example, the speaker may be driven to rotate by a motor.

As shown in fig. 6, the method for adjusting the angle of a speaker of a vehicle further includes: the position of the human ear determined from the image of the person in the vehicle is corrected with the position of the human ear determined from the audio signal of the person in the vehicle. Namely: the microphone at each position in the car collects the audio signal sent by the person in the car in real time, the ear position of the person in the car can be detected in real time, the ear position of the person identified by the image is compared, the specific ear position of the person in the car is calibrated in real time, and the determined ear position is more accurate.
