All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the common technology, the device cannot be comprehensively and accurately controlled due to the limitation of self-induction. Based on the above technical problems, the present embodiment provides an apparatus control method, which determines a sound source position by acquiring each sound data acquired by a plurality of sound acquisition devices, an aspect ratio of an electronic apparatus body, and a preset mode, so as to control a target apparatus to rotate according to the sound source position and rotation data obtained by the position of the target apparatus, and can accurately identify the sound source position to rotate the target apparatus, and specifically please refer to fig. 1, where fig. 1 is a flowchart of an apparatus control method provided in an embodiment of the present application, and specifically includes:
s101, acquiring each sound data acquired by a plurality of sound acquisition devices arranged at different positions on the electronic equipment body.
The electronic device body is not limited in this embodiment, and may be any one of a large-screen display, a common display, and a projection screen, or any other electronic device body, where a user may perform custom setting according to actual needs, and the electronic device is generally rectangular, and it may be understood that the electronic device may include an electronic device body, a CPU, and a target device. The aspect ratio of the electronic device body is not limited in this embodiment, and the aspect ratio of the general electronic device body is 4:3 and 16:9, but may be a similar ratio of 16:9, such as 15:9 or 16:10. A sound collection device such as a microphone or decibel meter may collect sound data in the current environment. The number of the sound collection devices is not limited in this embodiment, and may be 3 or 4 or 5 or other numbers. It is noted that the plurality of sound collection devices are disposed at different positions of the electronic device body, wherein the different positions are distributed to obtain the overall sound data. The present invention can be applied to any electronic device, and the electronic device can be manufactured by a method of manufacturing an electronic device. Preferably, the number of the sound collecting devices is four, and the sound collecting devices are arranged at four corners of the surface of the electronic equipment body. When the distance between the sound source and the Z axis direction of the electronic equipment body is 35cm to 100cm, including the endpoint value, the angle error detected by the XY axis is within +/-7 degrees; when the distance between the sound source and the Z-axis direction of the electronic equipment body exceeds 100cm, the angle error detected by the XY axis is within +/-3 degrees. Because the distance judgment that the software generates errors by using the loudspeaker in the conference is considered, further, the method can further comprise the step of determining a preset mode, wherein the preset mode can be a short-distance mode or a long-distance mode or a custom mode. The main purpose of this step is to initially determine the sound source position. The size of the Z-axis coordinate value is determined according to a preset mode, and a specific user can customize setting. When the mode is a close-range mode, the corresponding Z-axis coordinate value is 45cm; in the case of the remote mode, the corresponding Z-axis coordinate value is 200cm, and of course, the user may set the Z-axis coordinate value in a user-defined manner, so long as the purpose of the present embodiment can be achieved.
S102, determining a sound source position according to the position of the sound collecting device, all sound data and a preset mode, wherein the sound source position comprises an X-axis coordinate value, a Y-axis coordinate value and a Z-axis coordinate value, and the Z-axis coordinate value is determined by the preset mode.
The sound data may be the intensity of sound, which may be expressed in decibels. Because of the propagation characteristics of sound, sound wave energy attenuates with increasing distance when propagating in air, mainly the sound level attenuates due to air absorption, and therefore the size of sound data indicates the size of the distance of the sound source position, the larger the sound data is, the smaller the distance of the sound collecting device is. Further, determining the sound source position according to the position of the sound collecting device, all sound data and a preset mode includes: determining X-axis coordinate values and Y-axis coordinate values of the sound source positions according to the positions of the sound data and the sound collecting devices; and determining the sound source position according to the Z-axis coordinate value, the X-axis coordinate value and the Y-axis coordinate value.
The X-axis coordinate value and the Y-axis coordinate value of the sound source position may be determined from the sound data. Specifically, when the number of sound collection devices is 4 and the sound collection devices are respectively disposed at four corners of the electronic device body (the aspect ratio is 16:9), the 4 sound collection devices are A, B, C, D, and referring to fig. 2 specifically, corresponding sound data are 150, 76, 128, 66, and corresponding coordinates are (0, 9), (16, 9), (0, 0), and 16,0). Design (x) 1 ,y 2 ) Is the coordinates of the sound source position, y 1 Is the longitudinal distance, x, of A and B to the sound source location 2 Is the lateral distance of B and D to the sound source position, a is the distance of a to the sound source position, B is the distance of B to the sound source position, C is the distance of C to the sound source position, and D is the distance of D to the sound source position.
x 1 +x 2 ＝16，y 1 +y 2 ＝9，x 1 2 +y 1 2 ＝a 2 ，x 2 2 +y 1 2 ＝b 2 ，x 1 2 +y 2 2 ＝c 2 ，x 2 2 +y 2 2 ＝d 2 A/b=150/76, b/d=76/66, a/c=150/128, and x is obtained by the above formula 1 、x 2 、y 1 、y 2 And obtaining the X-axis coordinate value, the Y-axis coordinate value and the Z-axis coordinate value determined by a preset mode of the sound source position.
Based on the above principle, 3 sound collection devices or other number of sound collection devices may be further provided, and reference is made to the four sound collection devices for a specific calculation method, which is not described in detail in this embodiment.
S103, determining rotation data of the target device according to the sound source position and the position of the target device.
After knowing the position of the sound source on the XY axis, selecting a distance value of the Z axis according to a preset mode selected by a user, wherein the Z axis is 45cm when the Z axis is set in the short-distance mode; in the remote mode, the Z-axis is 200cm. And then calculating a Y-axis angle value alpha of the top edge of the electronic equipment body from the sound source and an X-axis angle value beta of the target equipment and the sound source parallel position from the sound source according to the trigonometric function. Referring to fig. 3 specifically, fig. 3 is an angle schematic diagram of a target device from a sound source position according to an embodiment of the present application. P is the target device location and Q is the sound source location. At this time, rotation data is acquired, and the Y-axis angle value alpha of the top edge from the sound source and the X-axis angle value beta of the middle of the target device body from the sound source parallel to the sound source are obtained so as to enable the target device to face the sound source. The present embodiment is not limited to the target device, and may be any one of an imaging device, a display, an ultrasonic sensor, and an energy detector.
In general, the target device is disposed on a central axis of the electronic device body, the specific target device may be a camera, the electronic device body may be a display screen, and in a conference, a real-time image of a speaker needs to be displayed on the screen generally.
S104, controlling the target equipment to rotate according to the rotation data.
The CPU controls the target device to rotate according to the rotation data.
Based on the above technical scheme, in this embodiment, by acquiring each sound data acquired by a plurality of sound acquisition devices, the aspect ratio of the electronic device body, and the preset mode, the sound source position is determined, so that the target device is controlled to rotate according to the sound source position and the rotation data obtained by the position of the target device, and the sound source position can be accurately identified to rotate the target device.
Further, determining the sound source position from all sound data includes: judging whether the sound data is legal sound data or not; if the sound data is legal sound data, the sound source position is determined according to all the sound data.
Specifically, a database of legal sound data may be preset, where corresponding voiceprint data may be stored, and after the sound data is collected, the sound data includes sound intensity and also includes voiceprint data. And matching the voiceprint data in the sound data with the database, and if the matching is successful, determining the sound source position according to all the sound data. Therefore, whether the sound data are legal sound data or not is judged through setting, the control of the target equipment is realized more pertinently, and interference caused by other illegal sound data is avoided.
Further, acquiring each of the sound data acquired by the plurality of sound acquisition devices provided at different positions includes: judging whether the change value of the sound data is larger than a preset threshold value or whether the sound data is 0; if the change value of the sound data is greater than the preset threshold value or the sound data is 0, the preset mode is redetermined, and the step of acquiring each sound data acquired by the plurality of sound acquisition devices arranged at different positions is executed.
In order to prevent abrupt change of the sound source position or use a loudspeaker when the change value of the sound data is greater than a preset threshold or the sound data is 0, the user may determine a new preset mode to reduce errors, for example, change the current close range mode to the far range mode or user-defined setting when the change value of the sound data is greater than the preset threshold; and when the rising change value of the sound data is larger than a preset threshold value, changing the current long-distance mode into a short-distance mode or setting by user definition. Therefore, the preset mode is adjusted by judging the change of the sound data, so that the accuracy of data acquisition is realized, and the accuracy of target equipment control is further improved.
Further, after controlling the rotation of the target device according to the rotation data, the method further includes: when the electronic equipment is turned off and the target equipment does not recover the original position, the target equipment is controlled to automatically calibrate the angle after the electronic equipment body is restarted, and the original position is recovered.
Specifically, after the user uses the electronic device, after the electronic device is turned on or turned off, the target device cannot return to the original position due to power failure, and the target device automatically calibrates the angle after the next power-on and returns to the original position, so that no deviation is caused when the angle rotation is executed next time.
