Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the matters relating to the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, subprograms, and the like.
The method, the device, the equipment and the storage medium for adjusting the microphone pickup aim to acquire the microphone pickup volume acquired by an array microphone by acquiring the rotation angle and the rotation direction of a display acquired by a triaxial acceleration sensor; when the sound pick-up volume is confirmed to be within a preset effective volume range, recording the rotation angle and the rotation direction; when the sound pickup volume is confirmed to be within a preset invalid volume range, determining the adjustment angle and the adjustment direction of the array microphone according to the rotation angle and the rotation direction, or determining the volume adjustment gain of the array microphone according to the sound pickup volume; and adjusting the sound pickup area of the array microphone according to the adjustment angle and the adjustment direction, or adjusting the sound pickup gain of the array microphone according to the volume adjustment gain. Compared with the traditional pickup adjusting technology, the pickup area is adjusted only through array microphone wave velocity forming, or the pickup volume is adjusted only through automatic gain, but when the angular deviation of the current speaker over against the microphone is large, if only gain is increased, the microphone frequency response and distortion can be changed differently, and the pickup quality of the microphone is influenced. And when carrying out pickup area adjustment, the pickup direction that sound localization confirmed is accurate inadequately, leads to the angle of pickup direction adjustment accurate inadequately, and under the noisy circumstances in use scene, the difficult circumstances of sound localization appears easily, and this leads to pickup direction adjustment also difficult relatively, can't guarantee the accuracy and the reliability of pickup direction adjustment. Based on this, embodiments of the present application provide a method, an apparatus, a device, and a storage medium for adjusting microphone pickup, so as to solve the problem in the prior art that a pickup area cannot be accurately located, implement accurate adjustment of the pickup area, and improve pickup quality.
The first embodiment is as follows:
fig. 1 is a flowchart of a microphone pickup adjustment method according to an embodiment of the present disclosure. The method for adjusting the microphone pickup provided in the embodiments may be performed by a microphone pickup adjusting apparatus, the microphone pickup adjusting apparatus may be implemented by software and/or hardware, and the microphone pickup adjusting apparatus may be formed by two or more physical entities or may be formed by one physical entity.
For example, referring to fig. 2, fig. 2 is a schematic structural diagram of a microphone pickup adjustment system according to an embodiment of the present disclosure. As shown in fig. 2, the microphone pickup adjustment system includes: the array microphone is used for collecting volume data, namely microphone pickup volume, the three-axis acceleration sensor is used for collecting rotation data, namely display rotation angle and rotation direction, and the main controller is used for determining adjustment parameters of the array microphone according to the volume data and the rotation data and adjusting the array microphone according to the adjustment parameters.
For the convenience of understanding, the main controller is used as the microphone pickup adjustment device in the embodiment for exemplary description. Specifically, referring to fig. 1, a microphone pickup adjustment method provided in the embodiment of the present application includes:
s101, obtaining a display rotation angle and a display rotation direction collected by a triaxial acceleration sensor, and obtaining microphone pickup volume collected by an array microphone.
Exemplarily, referring to fig. 3, fig. 3 is a schematic structural diagram of a screen of a kiosk according to an embodiment of the present application before rotation. As shown in fig. 3, the all-in-one machine includes: the microphone array comprises a rotating shaft, a support, a display, an array microphone and a three-axis acceleration sensor, wherein the display is installed on the support through the rotating shaft, the array microphone and the three-axis acceleration sensor are installed on the display, and a dotted line area is a current pickup area of the array microphone. The display is perpendicular to the X axis, the support is parallel to the Z axis, and the Y axis, the X axis and the Z axis are perpendicular to each other. The display can be rotated clockwise or counterclockwise about the Y-axis, it being understood that the display is not rotated perpendicular to the X-axis. When the display rotates, the display drives the three-axis acceleration sensor arranged inside to rotate, the three-axis acceleration sensor detects the acceleration of the display in the directions of the Y axis, the X axis and the Z axis, and the rotation angle and the rotation direction of the display are calculated according to the acceleration in the directions of the Y axis, the X axis and the Z axis. Because the triaxial acceleration sensor, the display and the array microphone rotate synchronously, the rotation angle and the rotation direction measured by the triaxial acceleration sensor can be used as the rotation angle and the rotation direction of the display and the array microphone, and then the position of a sound pickup area after rotation can be determined through the rotation angle and the rotation direction of the array microphone. Specifically, assume that the state of the display in fig. 3 is the initial state, i.e., the display is perpendicular to the X-axis. At this time, the sound pickup area of the array microphone is an initial sound pickup area, and the angle of the initial sound pickup area is assumed to be 0 ° and the direction is the right front of the display.
Further, referring to fig. 4, fig. 4 is a schematic structural diagram of a screen of an all-in-one machine provided in an embodiment of the present application after rotation. As shown in fig. 4, assuming that the display is rotated clockwise by an angle θ, the array microphone rotates along with the rotation of the display, and the initial sound pickup area rotates to the first sound pickup area, that is, the first sound pickup area is the sound pickup area of the current array microphone. Understandably, when the display rotates clockwise by an angle theta, the three-axis acceleration sensor acquires that the rotation angle of the display is theta degrees, and the rotation direction is the clockwise rotation direction.
And S102, recording the rotation angle and the rotation direction when the sound pickup volume is confirmed to be within a preset effective volume range.
For example, the sound volume collected by the array microphone is one of the criteria for determining whether the current sound pickup area is appropriate, if the sound volume is greater than or equal to the volume threshold, it indicates that the sound volume collected by the current array microphone meets the volume requirement of the user, and if the sound volume is less than the volume threshold, it indicates that the sound volume collected by the current array microphone does not meet the volume requirement of the user, and at this time, the sound pickup parameter of the array microphone needs to be adjusted to meet the user requirement. It is understood that the volume threshold can be set according to the volume requirement of the user, and is not limited herein.
Specifically, refer to fig. 4, assume that after the initial pickup area has rotated first pickup area, pickup volume is greater than or equal to predetermined volume threshold, then first pickup area this moment is suitable pickup area, to suitable pickup area, need not to carry out pickup area's adjustment to array microphone, but need record the turned angle and the direction of rotation of showing the front bezel, after being convenient for adjust the display next time, can more accurately calculate the position of current array microphone's pickup area, in order to adjust current pickup area to suitable pickup area. Further, based on the rotation direction and the sound pickup area direction recorded in the last adjustment, the rotation angle and the sound pickup area angle recorded in the last adjustment are calculated, and the current sound pickup area angle and direction are recorded. For example, referring to fig. 4, the sound pickup area at the last adjustment is the initial sound pickup area, and the current sound pickup area is the first sound pickup area. According to the clockwise rotation direction and the initial direction (right ahead of the display), the rotation angle theta DEG and the initial angle 0 DEG are added, the first sound pickup area direction is obliquely above the display, the first sound pickup area angle is theta DEG, and the first sound pickup area angle and direction are recorded.
S103, when the sound pickup volume is confirmed to be within a preset invalid volume range, determining the adjustment angle and the adjustment direction of the array microphone according to the rotation angle and the rotation direction, or determining the volume adjustment gain of the array microphone according to the sound pickup volume.
For example, referring to fig. 4, assuming that after the initial sound pickup area is rotated to the first sound pickup area, the sound pickup volume is smaller than the volume threshold, at this time, it needs to be determined whether the first sound pickup area is a suitable sound pickup area, if the first sound pickup area is a suitable sound pickup area, the sound pickup gain of the array microphone needs to be adjusted, and if the first sound pickup area is not a suitable sound pickup area, the sound pickup area of the array microphone needs to be adjusted.
Specifically, referring to fig. 5, fig. 5 is a flowchart of an alternative specific determination of the adjustment angle and the adjustment direction. As shown in fig. 5, the specific flow of determining the adjustment angle and the adjustment direction includes:
s1031, calculating the rotation angle and the sound pickup area angle recorded in the last adjustment based on the rotation direction and the sound pickup area direction recorded in the last adjustment to obtain the current sound pickup area angle and direction;
and S1032, determining an adjustment angle and an adjustment direction according to the current pickup area angle and the current pickup area direction when the current pickup area angle is confirmed to be within a preset invalid angle range.
For example, referring to fig. 4, the sound pickup area at the last adjustment is the initial sound pickup area, and the current sound pickup area is the first sound pickup area. According to the clockwise rotation direction and the initial direction (right in front of the display), the rotation angle theta DEG and the initial angle 0 DEG are added, and the first sound pickup area direction is obliquely upward of the display, and the first sound pickup area angle is theta deg. Assuming that the preset effective angle range is (- γ °, + γ °), if γ ° < θ °, the current sound pickup area is not a suitable sound pickup area. Furthermore, the opposite direction of the current sound pickup area direction is taken as the adjustment direction of the array microphone, and the current sound pickup area angle is taken as the adjustment angle of the array microphone. Illustratively, referring to fig. 4, the first pickup area direction is an oblique upper direction of the display, and the opposite direction, i.e. an oblique lower direction of the display, is rotated from the oblique upper direction to the oblique lower direction, the display needs to be rotated counterclockwise, and then the adjustment direction of the array microphone is the counterclockwise direction. The first pickup area angle is θ °, and the adjustment angle of the array microphone is θ °.
Specifically, referring to fig. 6, fig. 6 is a flow chart illustrating an alternative specific determination of the volume adjustment gain. As shown in fig. 6, the specific determination process of the volume adjustment gain includes:
s1033, calculating the rotation angle and the sound pickup area angle recorded in the last adjustment based on the rotation direction and the sound pickup area direction recorded in the last adjustment to obtain the current sound pickup area angle and direction;
s1034, when the current sound pickup area angle is confirmed to be within the preset effective angle range, determining the volume adjustment gain of the array microphone according to the sound pickup volume and the volume threshold value.
For example, referring to fig. 4, assuming that the preset effective angle range is (- γ °, + γ °), if γ ° ≧ θ °, the current sound pickup area is a suitable sound pickup area, and at this time, it may be determined that the sound pickup gain is small, and the sound pickup gain needs to be adjusted, without adjusting the sound pickup area position.
And S104, adjusting the sound pickup area of the array microphone according to the adjustment angle and the adjustment direction, or adjusting the sound pickup gain of the array microphone according to the volume adjustment gain.
Specifically, if the adjustment angle and the adjustment direction are determined in the previous step, the sound pickup area of the array microphone is adjusted according to the adjustment angle and the adjustment direction. It should be noted that, after the sound pickup area of the array microphone is adjusted, the direction and angle of the sound pickup area are changed, and the recorded current direction and angle of the sound pickup area need to be modified according to the adjustment direction and adjustment angle. Since the sound pickup area is adjusted to the initial sound pickup area every adjustment, the direction and angle of the initial sound pickup area can be taken as the current sound pickup area after each adjustment of the sound pickup area. Exemplarily, referring to fig. 4, it is determined that the adjustment angle of the first sound pickup area is θ ° and the adjustment direction is counterclockwise, so that the first sound pickup area is rotated counterclockwise by θ °, and is transferred to the second sound pickup area, which is the sound pickup area of the current array microphone, it can be understood that the second sound pickup area and the initial sound pickup area are in the same area, so that the current sound pickup area direction and angle are recorded, that is, the current sound pickup area direction and angle are recorded as the right front and 0 ° of the display.
Specifically, if the volume adjustment gain is determined in the previous step, the pickup gain of the array microphone is adjusted according to the volume adjustment gain. It should be noted that although the current sound pickup area is still an appropriate sound pickup area, the current sound pickup area is still changed from the sound pickup area at the time of the previous adjustment, and therefore, it is necessary to record the current sound pickup area direction and angle so that the sound pickup area direction and angle at the next time can be accurately calculated from the current sound pickup area direction and angle in the following. Illustratively, referring to fig. 4, if the current sound pickup area is also the first sound pickup area, the first sound pickup area direction and angle are recorded, the current sound pickup area direction is recorded obliquely above the display, and the sound pickup area angle at the current time is recorded as θ °.
On the other hand, fig. 7 is a flowchart of another microphone pickup adjustment method according to an embodiment of the present application. As shown in fig. 7, the microphone pickup adjustment method includes:
s201, acquiring a rotation angle and a rotation direction of a display, which are acquired by a triaxial acceleration sensor, and acquiring microphone pickup volume acquired by an array microphone;
s202, judging whether the sound collecting volume is in a preset invalid volume range, executing S203 when the sound collecting volume is confirmed to be in the preset invalid volume range, and executing S213 when the sound collecting volume is confirmed to be in the preset valid volume range;
s203, acquiring the angle and the direction of the current pickup area;
s204, judging whether the current sound pickup area angle is within a preset invalid angle range, executing S205 when the current sound pickup area angle is determined to be within the preset invalid angle range, and executing S209 when the current sound pickup area angle is determined to be within the preset valid angle range;
s205, determining an adjustment angle and an adjustment direction according to the angle and the direction of the current pickup area;
s206, adjusting the sound pickup area of the array microphone according to the adjustment angle and the adjustment direction;
s207, recording the current pickup area angle and direction as a preset initial angle and initial direction;
s208, judging whether the sound pickup volume is in an invalid volume range, executing S209 when the sound pickup volume is confirmed to be in a preset invalid volume range, and ending the operation when the sound pickup volume is confirmed to be in a preset valid volume range;
s209, determining the volume adjustment gain of the array microphone according to the pickup volume and the volume threshold;
s210, adjusting the pickup gain of the array microphone according to the volume adjustment gain;
s211, recording the angle and the direction of the current sound pickup area;
s212, judging whether the sound volume is in an invalid volume range, executing S205 when the sound volume is confirmed to be in a preset invalid volume range, and finishing the operation when the sound volume is confirmed to be in a preset valid volume range;
and S213, recording the rotation angle and the rotation direction, and finishing the operation.
Specifically, the specific implementation process of S201 may refer to S101, the specific implementation processes of S202 and S213 may refer to S102, and the specific implementation processes of S202 to S205 and S209 may refer to S103, and the specific implementation processes of S206 and S210 may refer to S104.
For example, after confirming that the current sound pickup area angle is within the invalid angle range, the adjustment angle and the adjustment direction need to be determined so as to adjust the sound pickup area to the initial sound pickup area according to the adjustment angle and the adjustment direction. However, in this case, there may be a case where, because the sound pickup gain of the microphone array is small, the sound pickup volume cannot meet the volume threshold required by the user regardless of whether the sound pickup area is in an appropriate sound pickup area, and at this time, the sound pickup gain needs to be adjusted. Specifically, after the pickup area is adjusted to the initial pickup area, whether the pickup volume is smaller than a volume threshold value or not is judged, if the pickup volume is smaller than the volume threshold value, the volume gain adjustment of the array microphone is determined according to the difference value or the ratio between the pickup volume and the volume threshold value, the pickup area is adjusted according to the volume gain adjustment, and the current angle and direction of the pickup area are recorded again.
Illustratively, after confirming that the current sound pickup area angle is within the valid angle range, it is necessary to determine a volume adjustment gain to adjust the sound pickup gain according to the volume adjustment gain. However, there may be a case where the area where the user is located is within the range of the angle threshold, but is just opposite to the current sound pickup area, and even if the current sound pickup area is in the appropriate sound pickup area, the sound pickup area needs to be adjusted to the initial sound pickup area because the area where the user is located changes. Specifically, after the pickup gain is adjusted, the current pickup area angle and direction are recorded, whether the pickup volume is smaller than a volume threshold value or not is judged, and if the pickup volume is smaller than the volume threshold value, the adjustment angle and the adjustment direction are determined according to the current pickup area angle and direction, so that the pickup area of the array microphone is adjusted according to the adjustment angle and the adjustment direction. After the sound pickup area is adjusted to the initial sound pickup area, the current sound pickup area direction and angle are recorded as the initial sound pickup area direction and angle.
In conclusion, the microphone pickup volume acquired by the array microphone is acquired by acquiring the display rotation angle and the display rotation direction acquired by the triaxial acceleration sensor; when the sound pick-up volume is confirmed to be within a preset effective volume range, recording the rotation angle and the rotation direction; when the sound pickup volume is confirmed to be within a preset invalid volume range, determining the adjustment angle and the adjustment direction of the array microphone according to the rotation angle and the rotation direction, or determining the volume adjustment gain of the array microphone according to the sound pickup volume; and adjusting the sound pickup area of the array microphone according to the adjustment angle and the adjustment direction, or adjusting the sound pickup gain of the array microphone according to the volume adjustment gain. Through the technical means, the rotation angle and the rotation direction of the pickup area of the array microphone are accurately acquired through the triaxial acceleration sensor, and the pickup area is accurately monitored through double threshold monitoring of the volume threshold and the angle threshold. Through the position adjustment to the pickup area and the cooperation adjustment of pickup gain for pickup adjustment is more accurate reliable, improves array microphone's pickup quality.
