In this embodiment, the terminal may be an audio device, or may be a control terminal or a server of the audio device. The following description will take an example in which the embodiment terminal is an audio device. It should be noted that the audio device may be a smart speaker.
Optionally, the audio device is provided with a display screen.
Optionally, the audio device may be further provided with a camera; or the camera device is arranged in the action space of the audio equipment, and the terminal is communicated with the camera device through data communication. The camera device can be used for collecting gesture instructions made by a user. The following description will be made taking an example in which the image pickup device is provided in an audio apparatus.
Optionally, in the first preset duration, the user makes a gesture instruction in a shooting area of the image capturing device, and the terminal may collect, through the image capturing device, the gesture instruction made by the user as the first gesture instruction.

It should be noted that, the terminal may identify a preset mark point in the hand image according to the hand image corresponding to the first gesture instruction, and use the position of the preset mark point as the target coordinate, for example, may set the fingertip in the hand image as the preset mark point, use the position of the fingertip as the target coordinate, collect the coordinate displacement corresponding to the fingertip, change the coordinate of the fingertip from the first coordinate to the second coordinate in the first preset duration, set the coordinate of the audio device as the origin of coordinates, and determine the first rotation angle and the first rotation direction according to the first coordinate, the second coordinate and the origin of coordinates.
Alternatively, the terminal may store different corresponding relations between the first gesture instructions and the first rotation directions in advance, and when the terminal detects the first gesture instructions within a first preset time period, the terminal may acquire the corresponding first rotation directions according to the first gesture instructions, and acquire a preset angle as the first rotation angle (the preset angle may be the first preset angle, and the value range of the first preset angle may be 10 ° -45 °). For example, the terminal may save that the first rotation direction corresponding to the right finger command is a counterclockwise rotation direction, and the first rotation direction corresponding to the left finger command is a clockwise rotation direction, and the first preset angle is 20 °, and when the terminal detects that the first gesture command is a right hand command, the obtained first rotation direction is a counterclockwise rotation direction, and the first rotation angle is 20 °.
It should be noted that the first preset duration may be set according to actual situation requirements, and may be selected from 1 second to 10 seconds.
And step S20, controlling the display screen of the audio equipment to rotate according to the first rotating direction and the first rotating angle.
Optionally, the display screen is arranged on the audio device through a rotatable structure, and the terminal can control the rotation of the display screen by controlling the rotation of the rotatable structure; optionally, the audio device is provided with or mounted on a rotatable base, and the terminal is operable to control rotation of the display screen by controlling rotation of the rotatable base.
Optionally, after determining the first rotation direction and the first rotation angle of the display screen according to the first gesture instruction, the terminal can control the display screen to rotate by the first rotation angle in a direction corresponding to the first rotation direction through the motor.
In one embodiment, when a first gesture instruction of a user is detected, determining a first rotation direction and a first rotation angle according to the first gesture instruction; and controlling the display screen of the audio equipment to rotate according to the first rotating direction and the first rotating angle. Therefore, the user can control the display screen of the audio device to rotate only by making gesture instructions, and even if the user is in a long distance, the user can also control the display screen to rotate, so that the user can conveniently adjust the viewing angle of the display screen of the audio device.
In a second embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, the step of determining the first rotation direction and the first rotation angle according to the first gesture command when the first gesture command of the user is detected within the first preset time period includes:
step S11, when a first gesture instruction of a user is detected within a first preset time period, determining the change of a target coordinate within the first preset time period according to the gesture change corresponding to the first gesture instruction.
And step S12, determining a first rotation direction and a first rotation angle according to the change of the target coordinates and the coordinates of the audio equipment within the first preset time period.
In this embodiment, after detecting a first gesture instruction of a user within a first preset duration, the terminal obtains a hand image corresponding to the first gesture instruction, then identifies a preset mark point in the hand image, and uses a position of the preset mark point as a target coordinate (specific coordinate data may use a position of the audio device as a coordinate origin, and establish a three-dimensional coordinate system for determination). The preset mark point may be a palm center of the user or a fingertip of the user, and the preset mark point is taken as an example of the fingertip of the user.
Optionally, when the preset mark point is a fingertip of the user, the terminal may identify a fingertip image in the hand image through a fingertip identification algorithm, and then determine the target coordinate according to the position of the fingertip of the user relative to the audio device. It should be noted that, the fingertip recognition algorithm may adopt a gravity center distance method, and each peak value obtained by recognizing the distances between all points of the edge of the hand and the palm center traverse clockwise or anticlockwise corresponds to a finger fingertip (if the user stretches out only one finger, only one peak value is obtained), and the generation position of the peak value is the fingertip position. The fingertip recognition algorithm can be divided into 5 steps: (1) gaussian blur is performed on the hand image; (2) skin color segmentation; (3) finding a hand contour; (4) calculating moment, namely palm center; (5) looking for a user's fingertip.
When the user simultaneously extends a plurality of fingers, the average value of the target coordinates is calculated as the final target coordinates after obtaining a plurality of target coordinates.
And establishing a three-dimensional coordinate system by taking the position of the audio equipment as a coordinate origin, taking the position of a user fingertip as a target coordinate in a first preset time period, and changing the target coordinate from the first coordinate to the second coordinate in the first preset time period to obtain a connecting line a between the coordinate origin and the first coordinate and a connecting line b between the coordinate origin and the second coordinate, so that an angle beta between the connecting line a and the connecting line b and a direction I of the first coordinate pointing to the second coordinate can be calculated. When the display screen can rotate in any direction in the three-dimensional space, the angle beta and the direction one are the first rotation angle and the first rotation direction, and when the display screen rotates along a certain plane, the angle beta and the angle component beta 'of the direction one on the rotation plane of the display screen and the direction component direction two are used as the first rotation angle and the second rotation direction, for example, when the display screen rotates along a horizontal plane, the angle beta and the angle component beta' of the direction one on the horizontal plane and the direction two are used as the first rotation angle and the first rotation direction. The first rotation angle is less than or equal to 180 °.
Taking a rotation plane of a display screen as a horizontal plane as an example, referring to fig. 6, the intelligent device detects a first gesture instruction of a user within a first preset period of time, and obtains a change of a fingertip from a first coordinate 22 to a second coordinate 21, wherein a connection line between the first coordinate 22 and an origin O is 40, a connection line between the second coordinate 21 and the origin O is 30, and an included angle β between the connection line 30 and the connection line 40 and a direction from the first coordinate 22 to the second coordinate 21 are directions one. Because the included angle β may not be in a horizontal plane, when the rotation plane of the display screen is a horizontal plane, an included angle component β 'of the included angle β in the horizontal plane and a direction component direction two of the direction one in the horizontal plane are calculated, and the included angle component β' and the direction two are the first rotation angle and the first rotation direction.
It should be noted that, the terminal may divide the active space of the audio device into m×n grids in advance, each grid has its corresponding coordinate range, then determine the offset angle between each grid and the central line of the screen, after obtaining the target coordinates, further obtain the grid where the target coordinates are located, and then obtain the offset angle between the grid and the central line of the screen as the first rotation angle.
Alternatively, when the display screen of the audio device is rotatable by 360 °, two first rotation angles may be determined, and the two first rotation angles correspond to different first rotation directions (respectively, a counterclockwise rotation direction and a clockwise rotation direction). In order to reduce the power consumption of the audio device, therefore, the first rotation angle at which the angle is smallest of the two first rotation angles may be acquired as the finally determined first rotation angle, i.e., the determined first rotation angle is less than or equal to 180 °. When both the first rotation angles are 180 °, one of the first rotation angles may be selected as the determined first rotation angle.
Therefore, the user can control the display screen of the audio device to rotate only by making gesture instructions, and even if the user is in a long distance, the user can also control the display screen to rotate, so that the user can conveniently adjust the viewing angle of the display screen of the audio device.
In a third embodiment, as shown in fig. 4, after the step of controlling the rotation of the display screen of the audio device according to the first rotation direction and the first rotation angle, the method further includes:
and step S30, acquiring a second rotation angle and a second rotation direction when a second control instruction is detected within a second preset time period.
And S40, controlling the display screen to rotate according to the second rotation direction and the second rotation angle.
In this embodiment, after the terminal controls the display screen of the audio device to rotate according to the first rotation direction and the first rotation angle (i.e., after the display screen rotates for the first time), if the user is not satisfied with the viewing angle after the display screen rotates, a second control instruction may be sent within a second preset duration to control the display screen to rotate again, where the second control instruction may be a gesture instruction or a voice instruction.
It should be noted that, the scenario that the user continues to make the gesture instruction may be to continue to hold the gesture corresponding to the first gesture instruction, or may be to make a gesture instruction again.
Optionally, after the terminal controls the display screen to rotate according to the first rotation direction and the first rotation angle, the gesture instruction of the user detected in the second preset duration may be used as a second control instruction, and the first voice instruction of the user detected in the second preset duration may also be used as a second control instruction. The second preset time length can be set according to actual situation requirements, and can be selected to be 5 seconds to 30 seconds.
Optionally, after detecting the second control instruction, when the second control instruction is a first voice instruction of the user, the first voice instruction may include direction and/or angle information, the angle information and the direction information may be obtained by parsing according to the first voice instruction of the user, and as the second rotation angle and the second rotation direction, for example, when the user sends the first voice instruction that "clockwise rotates by 5 °", the user may determine that the second rotation angle is 5 ° at the same time, and the second rotation direction is clockwise.
Optionally, when the second control instruction is a second gesture instruction of the user, the second rotation angle may be obtained according to a preset rule, that is, when the second gesture instruction of the user is detected, the preset angle is obtained as the second rotation angle, where the preset angle is smaller than or equal to the first rotation angle, and the direction indicated by the second gesture instruction is used as the second rotation direction or the preset direction is obtained as the second rotation direction. For example, the number of fingertips in the gesture image corresponding to the gesture instruction is identified, a corresponding preset angle is obtained according to the number of fingertips, the corresponding preset angle is used as a second rotation angle, and the larger the number of fingertips obtained by identification is, the larger the second rotation angle obtained by determination is; for example, when the rotation angle corresponding to one fingertip is 5 °, and when the number of fingertips corresponding to the second gesture command is 2, the obtained second rotation angle is 10 °, and in addition, the direction pointed by the fingertips is identified as the second rotation direction, or the second rotation direction is determined according to the preset direction. The second rotation angle is finely adjusted by a user based on the position of the display screen after rotating according to the first rotation angle, so that the preset angle can be a smaller angle value, the value range of the preset angle can be 1-10 degrees, and the preset angle is set according to practical conditions. The range of the corresponding rotation angle of one fingertip can be 5 degrees to 10 degrees. For example, when the rotation angle corresponding to one fingertip is 5 °, and when the number of fingertips corresponding to the second gesture command is 2, the obtained second rotation angle is 10 °
Optionally, after determining the second rotation direction corresponding to the second control instruction and determining to obtain the second rotation angle, the audio device may control the display to rotate again according to the second rotation direction and the second rotation angle.
Therefore, after the display screen is rotated for the first time, the display screen may not be rotated to the direction expected by the user completely, and at this time, the user can make similar gesture instructions or voice instructions again to make small correction rotation on the display screen, so that the viewing requirement of the user is met.
In a fourth embodiment, as shown in fig. 5, on the basis of the embodiments in fig. 2 to 4, the audio device is provided with an image capturing device, and before the step of determining the first rotation direction and the first rotation angle according to the first gesture command when the first gesture command of the user is detected within the first preset duration, the method further includes:
and step S50, when a second voice instruction of the user is received, determining the position of the user according to the second voice instruction.
Step S51, determining a third rotation direction and a third rotation angle according to a positional relationship between the position of the user and the shooting area of the imaging device.
And step S52, controlling the image pickup device to rotate according to the third rotation direction and the third rotation angle.
In this embodiment, the audio device is provided with a microphone array, and when the terminal detects the second voice command, that is, detects the specific voice command sent by the user through the microphone array, the terminal can obtain the position of the user through the algorithm processing of sound source localization, and the camera device rotates to face the user and collects the image information of the user.
Optionally, before detecting the first gesture instruction, the terminal may determine the position of the user by first receiving the time of the voice information before and after at least two microphones on the microphone array and the sound intensity of the voice information detected by at least two microphones when receiving the second voice instruction sent by the user.
Optionally, the audio device is provided with an image pickup means.
Optionally, the camera device may be connected to the audio device through a rotatable structure, and the terminal may rotate by controlling the rotatable structure to control rotation of the camera device; the camera device can also be arranged on a display screen of the audio equipment, and the terminal can control the rotation of the display screen so as to realize the control of the rotation of the camera device.
Alternatively, the terminal may determine the photographing region of the image pickup device in advance according to the current photographing wide angle and photographing accuracy of the image pickup device. It should be appreciated that the imaging area of the imaging device may be substantially a sector.
Optionally, after the position of the user is obtained according to the second voice command, the terminal may determine a third rotation direction and a third rotation angle for controlling rotation of the image capturing device according to the position of the user and the current capturing area of the image capturing device, so as to adjust a spatial position where the capturing area is located, so that the position of the user is located in the capturing area.
Optionally, after determining the third rotation direction and the third rotation angle, the terminal controls the image capturing device to rotate according to the third rotation angle and the third rotation direction, so that the position of the user is in the capturing area of the image capturing device.
It should be understood that, after the audio device obtains the user position according to the second voice command, it may first determine whether the user position is in the shooting area, and if not, execute steps S50 to S52; if yes, the terminal directly executes step S10.
Therefore, the user can be in the shooting area without actively searching the shooting area of the camera device, and is convenient to make gesture instructions to the audio equipment.
In addition, the invention also provides an audio device, which comprises a memory, a processor and a control program of the audio device, wherein the control program of the audio device is stored on the memory and can be run on the processor, and the processor realizes the steps of the control method of the audio device when executing the control program of the audio device.
