Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
In a first embodiment of the volume real-time adjustment method, referring to fig. 1, the volume real-time adjustment method includes:
step S10, detecting whether the position interval of the target to be detected changes in real time through the intelligent camera;
in this embodiment, it should be noted that the volume real-time adjusting method is applied to an intelligent camera, and a sound system is deployed on the intelligent camera, where the sound system includes a speaker and a microphone and is used for realizing a call of the intelligent camera in different monitoring areas. For example, in a home residence, a call between a room 1 and a room 2 monitored by an intelligent camera can be realized.
The method comprises the steps of detecting whether a position interval of a target to be detected changes in real time through the intelligent camera, specifically, tracking the target to be detected through the intelligent camera, and detecting whether the position interval of the target to be detected changes in real time. It should be noted that the purpose of detecting the position change range of the target to be detected can be achieved by detecting whether the position interval of the target to be detected changes, once the position interval of the target to be detected changes, it can be determined that the target to be detected changes greatly, a proper volume interval of the target to be detected also changes, and then volume adjustment can be performed, wherein one volume interval corresponds to one volume. In the embodiment of the present application, the method of adjusting the volume by detecting whether the position of the target to be detected changes obviously, but the method does not need to adjust the volume, and the method of adjusting the volume by detecting whether the position of the target to be detected changes obviously is more reasonable, that is, when the position of the target to be detected changes, the method needs to adjust the volume, so as to avoid the situation that the volume needs to be adjusted by misjudging under the condition that the position changes but the volume does not need to be adjusted, compared with the method of adjusting the volume by detecting whether the position of the target to be detected changes, the method of adjusting the volume by detecting whether the position of the target to be detected changes in the embodiment of the present application judges whether the volume needs to be adjusted more accurately, the accuracy of volume adjustment is improved.
The method comprises the following steps of detecting whether the position interval of a target to be detected changes in real time through the intelligent camera, wherein the steps comprise:
step A10, detecting a current receiving volume interval of sound received by a sound system in the intelligent camera;
step A20, if the current receiving volume interval changes, determining that the position interval where the target to be detected is located changes;
step A30, if the current receiving volume interval does not change, determining that the position interval where the target to be detected is located does not change.
In this embodiment, it should be noted that, because the position of the intelligent camera is not changed, and the closer the distance between the target to be detected and the intelligent camera is, the greater the sound received by the sound system in the intelligent camera is; the farther the distance between the target to be detected and the intelligent camera is, the smaller the sound received by the sound system in the intelligent camera is. And then according to the change of the volume interval of the volume received by the sound system, whether the position interval of the target to be detected changes can be judged.
Detecting a current receiving volume interval of sound received by a sound system in the intelligent camera, specifically, detecting a sound volume value of sound received by the sound system in the intelligent camera to obtain a current receiving volume value, and determining the volume interval where the receiving volume value is located according to the size of the current receiving volume value to obtain the current receiving volume interval; acquiring a previous receiving volume interval of the target to be detected at a last time point, and if the current receiving volume interval is inconsistent with the previous receiving volume interval, judging that the current receiving volume interval changes, and further judging that a position interval where the target to be detected is located changes; and if the current receiving volume interval is consistent with the previous receiving volume interval, judging that the current receiving volume interval is not changed, and further judging that the position interval where the target to be detected is located is not changed.
The step of detecting whether the position interval of the target to be detected changes in real time through the intelligent camera further comprises:
step B10, controlling the intelligent camera to follow the target to be detected, and detecting whether the intelligent camera rotates within a range;
in this embodiment, it should be noted that, because the intelligent camera always follows the target to be detected, and the focusing center of the intelligent camera is the target to be detected, once the target to be detected has moved to a larger extent, that is, the position interval where the target to be detected is located has changed, the intelligent camera will rotate to an angle that can focus the target to be detected in order to continue focusing the target to be detected, and if the target to be detected has moved to a smaller extent, the intelligent camera will not rotate.
The method comprises the steps of controlling the intelligent camera to follow a target to be detected and detecting whether the intelligent camera rotates within a preset time period, specifically, controlling the intelligent camera to follow the target to be detected in real time and judging whether the intelligent camera rotates within the preset time period by detecting the change range of the rotation angle of the intelligent camera within the preset time period.
In step B10, the step of detecting whether the intelligent camera has interval rotation includes:
step B11, detecting the rotation angle of the intelligent camera in real time to obtain a real-time rotation angle;
step B12, judging whether the change amplitude of the real-time rotation angle is larger than a preset angle change amplitude threshold value;
step B13, if yes, judging that the intelligent camera has interval rotation;
and step B14, if not, judging that the intelligent camera does not generate interval rotation.
In this embodiment, specifically, an angle between the intelligent camera and the rotation reference line is detected in real time to obtain a real-time rotation angle of the intelligent camera, and it is determined whether a variation range of the real-time rotation angle within a preset time period is greater than a preset angle variation range threshold value, if the variation range of the real-time rotation angle within the preset time period is greater than the preset angle variation range threshold value, it is determined that the intelligent camera has interval rotation, and if the variation range of the real-time rotation angle within the preset time period is not greater than the preset angle variation range threshold value, it is determined that the intelligent camera has not interval rotation. The rotation reference line can be realized as a horizontal line or a vertical line, and the intelligent camera can rotate in the vertical direction in an interval mode. The intelligent camera rotates in an interval to indicate that the intelligent camera is converted from a current rotation angle interval to another rotation angle interval, and the rotation angle interval corresponds to a position interval where a target to be detected is located and a volume interval of the intelligent camera one to one.
And step B20, if the generation interval of the intelligent camera head rotates, judging that the position interval where the target to be detected is located changes.
In this embodiment, specifically, if the intelligent camera generates a section rotation, it is determined that the section of the position where the target to be detected is located is changed, and if the intelligent camera does not generate a section rotation, it is determined that the section of the position where the target to be detected is located is not changed. Therefore, the purpose of judging whether the position interval of the target to be detected changes or not according to the rotation angle of the intelligent camera is achieved.
The step of detecting whether the position interval of the target to be detected changes in real time through the intelligent camera further comprises:
step C10, controlling the intelligent camera to follow the target to be detected, and detecting whether the intelligent camera rotates within a range;
in this embodiment, the detailed implementation of step C10 can refer to the content of step B10, and will not be described herein again.

step C30, if the current receiving volume interval changes, determining that the position interval where the target to be detected is located changes;
and step C40, if the current receiving volume interval does not change, determining that the position interval where the target to be detected is located does not change.
In this embodiment, when the intelligent camera rotates, the position interval where the target to be detected is located does not change under some conditions, for example, when the target to be detected moves along a direction parallel to the intelligent camera, the position interval where the target to be detected is located does not change basically; when the target to be detected moves along the arc with the intelligent camera as the circle center and the fixed radius, the position interval where the target to be detected is located does not change.
Specifically, detecting a volume value of sound received by a sound system in the intelligent camera to obtain a current received volume value, and determining a volume interval where the received volume value is located according to the size of the current received volume value to obtain a current received volume interval; acquiring a previous receiving volume interval of the target to be detected at a last time point, and if the current receiving volume interval is inconsistent with the previous receiving volume interval, judging that the current receiving volume interval changes, and further judging that a position interval where the target to be detected is located changes; and if the current receiving volume interval is consistent with the previous receiving volume interval, judging that the current receiving volume interval is not changed, and further judging that the position interval where the target to be detected is located is not changed. The last time point is the time point before the intelligent camera rotates. According to the embodiment of the application, on the basis of judging whether the position interval of the target to be detected changes or not by judging whether the intelligent camera rotates in the interval or not, whether the position interval of the target to be detected changes or not is further determined by utilizing the received change condition of the volume interval, the condition that the position interval of the target to be detected does not change when the intelligent camera rotates is eliminated, and the accuracy of judging whether the position interval of the target to be detected changes or not is improved.
After the step of detecting whether the intelligent camera rotates within a certain interval, the real-time volume adjusting method further includes:
step D10, if the intelligent camera does not rotate within the interval, detecting the current human body posture of the target to be detected through the intelligent camera, and acquiring the previous human body posture of the target to be detected at the last time point;
in this embodiment, it should be noted that, because the intelligent camera focuses on when shooting is the whole human body, and listen to the sound for the ear of human head, so in some cases, although the camera does not rotate, it still changes to wait to detect the interval of target position, for example, when human gesture is changed for the head to keep away from the gesture of lying of intelligent camera by the gesture of lying of head orientation intelligent camera, the intelligent camera can not rotate or interval rotation this moment, the interval of target position of head of waiting to detect has but changed, and then will influence the size of waiting to detect the target volume of listening to.
If the intelligent camera does not rotate within a certain interval, detecting the current human body posture of the target to be detected through the intelligent camera, and acquiring the previous human body posture of the target to be detected at the last time point, specifically, if the intelligent camera does not rotate, shooting the target to be detected through the intelligent camera to obtain a current shot image, and performing image recognition on the current shot image to obtain the current human body posture; and acquiring a previously shot image shot by the intelligent camera at the last time point, and performing image recognition on the previously shot image to obtain a previous human body posture.
The step of obtaining the current human body posture by performing image recognition on the current shot image comprises the following steps: classifying the shot images according to a preset image classification model to obtain image classification labels; and determining the current human body posture according to the image classification label.
And D20, judging whether the position interval of the target to be detected changes according to the current human body posture and the previous human body posture.
In this embodiment, whether the position interval where the target to be detected is located is changed or not is determined according to the current human body posture and the previous human body posture, specifically, whether the current human body posture is consistent with the previous human body posture is determined, and if the current human body posture is consistent with the previous human body posture, it is determined that the position interval where the target to be detected is located is not changed; and if the current human body posture is inconsistent with the previous human body posture, judging whether the position interval of the target to be detected is changed or not by judging whether the current human body posture and the previous human body posture belong to similar human body postures.
The step of judging whether the current human body posture and the previous human body posture belong to similar human body postures or not and whether the position interval of the target to be detected changes or not comprises the following steps:
judging whether the current human body posture belongs to a similar human body posture set corresponding to the previous human body posture, if not, judging that the position interval of the target to be detected is changed, and if not, judging that the position interval of the target to be detected is not changed. It should be noted that, in the embodiment of the present application, a set of similar human body postures is maintained for each human body posture, and when a target to be detected is converted from a human body posture to any human body posture in the set of similar human body postures corresponding to the human body posture, a position interval where the target to be detected is located does not change, so that a listening volume of the target to be detected cannot be greatly affected. According to the embodiment of the application, on the basis of whether the position interval of the target to be detected, which is judged by judging whether the intelligent camera rotates or not, changes, when the intelligent camera rotates, the position interval of the target to be detected is further judged by combining the change of the posture of the human body, so that the misjudgment of the condition that some intelligent cameras do not rotate but change the position interval of the target to be detected is avoided, and the accuracy of judging whether the position interval of the target to be detected changes or not is improved.
Before step S10, the method for adjusting the volume in real time further includes:
step T10, collecting sound pressure level data of a sound system in the intelligent camera at a preset position point;
and T20, establishing a mapping relation between the volume interval and the position interval according to the sound pressure level data.
In this embodiment, it should be noted that the preset location point is a suitable listening location point of a sound with a corresponding suitable sound pressure level. The sound pressure level data comprises a suitable sound pressure level corresponding to each preset location point.
Specifically, sound pressure level data of a sound system in the intelligent camera at least one preset position point is collected, the sound pressure level data is further divided into at least one volume interval, the distance between the preset position point corresponding to each volume interval and the position point of the intelligent camera is further obtained, the position interval corresponding to each volume interval is determined according to the distance between the preset position point corresponding to each volume interval, and the mapping relation between the volume intervals and the position intervals is established by correspondingly storing each volume interval and the corresponding position interval. For example, the sound pressure level range corresponding to the first grid volume (volume interval) is 30 db to 35 db, the distances between the corresponding position points are (0.5, 1, 1.6, 2.3, 3), the position interval corresponding to the first grid volume is 0 m to 3 m, for example, the sound pressure level range corresponding to the second grid volume (volume interval) is 35 db to 40 db, the distances between the corresponding position points are (3, 3.7, 4.5, 5.4, 6.5), and the position interval corresponding to the first grid volume is 3 m to 6.5 m.
Step S20, if the position interval of the target to be detected changes, detecting the actual position interval of the target to be detected relative to the intelligent camera;
in this embodiment, specifically, if the position interval where the target to be detected is located changes, the actual distance between the target to be detected and the intelligent camera is detected, and the actual position interval where the target to be detected is located is determined according to the size of the actual distance.
The step of detecting the actual position interval of the target to be detected relative to the intelligent camera comprises the following steps:
e10, detecting the actual distance between the intelligent camera and the target to be detected, and determining the actual position interval according to the actual distance;
in this embodiment, specifically, the distance between the intelligent camera and the target to be detected is measured by the infrared device on the intelligent camera to obtain a measured distance, the measured distance is used as an actual distance, and an actual position interval where the actual distance is located is queried according to the size of the actual distance.
Wherein the step of detecting the actual distance between the intelligent camera and the target to be detected comprises:
step E11, measuring the distance between the intelligent camera and the target to be detected through the infrared device on the intelligent camera to obtain a measured distance;
in this embodiment, the distance between the intelligent camera and the target to be detected is measured by the infrared device on the intelligent camera to obtain the measured distance, specifically, infrared rays are transmitted to the target to be detected by the infrared device on the intelligent camera and reflected infrared rays of the target to be detected are received, so as to determine a time interval from the transmission of infrared rays by the infrared device to the reception of infrared rays reflected by the target to be detected, and the distance between the intelligent camera and the target to be detected is calculated according to the time interval to obtain the measured distance.
Step E12, determining a distance compensation value according to the current human body posture of the target to be detected;
in this embodiment, it should be noted that, since the ear of the human being listens to the sound, the actual distance measured by the infrared ray is the distance from the point on the object to be detected closest to the camera to the intelligent camera, and then the volume compensation is directly performed according to the distance measured by the infrared device, there will be a certain error.
Determining a distance compensation value according to the current human body posture of the target to be detected, specifically, obtaining the current human body posture of the target to be detected, directly taking the measured distance as an actual distance if the current human body posture is consistent with a standard human body posture, and inquiring the distance compensation value corresponding to the current human body posture according to a mapping relation between the human body posture and the distance compensation if the current human body posture is inconsistent with the standard human body posture, wherein the standard human body posture is a human body posture in which the head of a human body is not far away from the camera, such as a standing posture or a lying posture in which the head faces the camera, and the nonstandard human body posture is a human body posture in which the head of the human body is far away from the camera, such as a lying posture in which the head of the human body is far away from the camera.
The step of detecting the actual position interval of the target to be detected relative to the intelligent camera further comprises:
and F10, detecting the actual rotation angle of the intelligent camera relative to the target to be detected, and determining the actual position interval according to the rotation angle.
In this embodiment, it should be noted that the intelligent camera follows the target to be detected, and when a position interval where the target to be detected is located changes, the intelligent camera rotates along with the target to be detected.
In this embodiment, specifically, an angle of the intelligent camera with respect to a rotation reference is measured, an actual rotation angle of the intelligent camera with respect to the detection target is obtained, and the actual position interval is determined according to the size of the actual rotation angle. Wherein the rotation reference may be set to a horizontal line or a vertical line.
The step of detecting the actual rotation angle of the intelligent camera relative to the target to be detected comprises the following steps:
step F11, measuring the rotation angle of the intelligent camera relative to the rotation reference to obtain a measured rotation angle;
in this embodiment, it should be noted that an angle sensor is disposed on the intelligent camera, and the angle sensor can measure a rotation angle of the intelligent camera relative to a rotation reference, so as to obtain a measured rotation angle.
Step F12, determining an angle compensation value according to the current human body posture of the target to be detected;
in this embodiment, specifically, a current human body posture of the target to be detected is obtained, if the current human body posture is consistent with a standard human body posture, the measured rotation angle is directly used as an actual rotation angle, and if the current human body posture is inconsistent with the standard human body posture, an angle compensation value corresponding to the current human body posture is queried according to a mapping relationship between the human body posture and the angle compensation, where the standard human body posture is a human body posture in which a head of a human body is a center of an image shot by an intelligent camera, and the intelligent camera focuses on the head of the human body, and in the standard human body posture, a correct corresponding relationship exists between the rotation angle and an actual distance interval. For example, assume that when the center of an image captured by the smart camera is a human leg, the human posture is a lying posture, and at this time, the human leg is within the corresponding distance interval, but the human head is not necessarily within the corresponding distance interval, and then the measured rotation angle needs to be compensated to obtain the actual rotation angle when the center of the image captured by the smart camera in the lying posture is the human head.
And step C13, calculating the actual rotation angle according to the angle compensation value and the measured rotation angle.
In this embodiment, it should be noted that the distance compensation value may be a specific angle value, or may be a compensation coefficient.
Calculating the actual rotation angle according to the angle compensation value and the measured rotation angle, and specifically, summing the angle compensation value and the measured rotation angle to obtain the actual rotation angle; or the product of the angle compensation value and the measured rotation angle is obtained to obtain the actual rotation angle. The embodiment of the application considers that the person listening to the sound is the ear, and the measurement rotating angle is compensated by detecting the human body posture of the target to be detected, so that the accuracy of measuring the actual rotating angle of the intelligent camera relative to the target to be detected when the volume is adjusted is improved, the rotating angle measurement error of the human body posture for carrying out the volume adjustment is eliminated, and then the actual position interval is determined according to the actual rotating angle with higher accuracy, and the accuracy of determining the actual position interval where the target to be detected is located can be improved
And step S30, adjusting the volume of the sound system in the intelligent camera in real time according to the current playing volume interval of the sound system in the intelligent camera and the actual position interval.
In this embodiment, specifically, according to a mapping relationship between a volume interval and a position interval, the current playing volume interval is used as an index, and a suitable position interval corresponding to the current playing volume interval is queried; and if the actual position interval is inconsistent with the proper position interval, adjusting the volume of the sound system in the intelligent camera from the current playing volume interval to a target volume interval corresponding to the actual position interval.
