Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0073] Embodiment 1

[0074] The present application embodiment provides a volume compensation optimization method. In the first embodiment of the volume compensation optimization method of the present application, refer to Figure 1 , the volume compensation optimization method comprises:

[0075] Step S10, detecting the actual distance between the smart camera and the target to be detected, and acquiring the current sound pressure level of the sound system in the smart camera;

[0076] In this embodiment, it should be noted that the volume compensation optimization method is applied to a smart camera, and the smart camera is deployed with a sound system, which includes a speaker and a microphone, for realizing calls between smart cameras in different monitoring areas. For example, in a family residence, calls can be realized between rooms on the first floor and rooms on the second floor monitored by a smart camera.

[0077] The current sound pressure level is the sound pressure level of the sound emitted by the current sound system, wherein the sound pressure level is a parameter describing the volume, and the unit is decibel. The target to be detected is the target person served by the sound system in the smart camera.

[0078] Detect the actual distance between the smart camera and the target to be detected, and obtain the current sound pressure level of the sound system in the smart camera. Specifically, detect the actual distance between the smart camera and the target to be detected by an infrared device on the smart camera, and obtain the current sound pressure level of the sound system in the smart camera.

[0079] Wherein, the step of detecting the actual distance between the smart camera and the target to be detected further includes:

[0080] The target to be detected is photographed by the smart camera to obtain a photographed image, and the actual distance between the smart camera and the target to be detected is detected by the photographed image and the focal length of the smart camera.

[0081] Step S20, determining a volume compensation value according to the current sound pressure level and the actual distance;

[0082] In this embodiment, the volume compensation value is determined according to the current sound pressure level and the actual distance. Specifically, according to the mapping relationship between the sound pressure level and the distance, the target sound pressure level corresponding to the actual distance is queried, and then the volume compensation value is determined according to the difference between the current sound pressure level and the target sound pressure level.

[0083] Wherein, the step of determining the volume compensation value according to the current sound pressure level and the actual distance comprises:

[0084] Step S21, obtaining a preset suitable distance corresponding to the current sound pressure level;

[0085] In this embodiment, the preset appropriate distance corresponding to the current sound pressure level is obtained. Specifically, according to the mapping relationship between the sound pressure level and the distance, the preset appropriate distance corresponding to the current sound pressure level is queried. It should be noted that the embodiment of the present application determines the mapping relationship between the sound pressure level and the distance corresponding to the sound system in the smart camera by performing a sound test on the smart camera in advance.

[0086] Step S22, determining whether the preset appropriate distance matches the actual distance;

[0087] In this embodiment, it is determined whether the preset appropriate distance matches the actual distance. Specifically, it is determined whether the difference between the preset appropriate distance and the actual matrix is ​​within a preset error range. If the difference between the preset appropriate distance and the actual matrix is ​​within the preset error range, it is determined that the preset appropriate distance matches the actual distance; if the difference between the preset appropriate distance and the actual matrix is ​​not within the preset error range, it is determined that the preset appropriate distance does not match the actual distance.

[0088] Step S23, if the preset appropriate distance does not match the actual distance, determining a volume compensation value according to the current sound pressure level and the actual distance;

[0089] Step S24: If the preset appropriate distance matches the actual distance, no volume compensation is performed on the sound system in the smart camera.

[0090] In this embodiment, specifically, if the preset appropriate distance does not match the actual distance, according to the mapping relationship between the sound pressure level and the distance, the appropriate sound pressure level corresponding to the actual distance is queried, and then the volume compensation value is determined according to the difference between the current sound pressure level and the appropriate sound pressure level; if the preset appropriate distance matches the actual distance, the sound system in the smart camera is not compensated for the volume.

[0091] Wherein, the step of determining the volume compensation value according to the current sound pressure level and the actual distance comprises:

[0092] Step A10, determining the appropriate sound pressure level at the actual distance according to the mapping relationship between the sound pressure level and the distance;

[0093] In this embodiment, specifically, according to the mapping relationship between the sound pressure level and the distance, the preset sound pressure level corresponding to the actual distance is queried, and the preset sound pressure level is used as the appropriate sound pressure level.

[0094] Wherein, the step of determining the appropriate sound pressure level at the actual distance according to the mapping relationship between the sound pressure level and the distance comprises:

[0095] Step A11, querying a preset sound pressure level corresponding to the actual distance according to the mapping relationship between the sound pressure level and the distance;

[0096] Step A12, detecting the current human posture of the target to be detected by the smart camera, and determining the sound pressure level compensation according to the current human posture;

[0097] Step A13: determining the appropriate sound pressure level according to the sound pressure level compensation and the preset sound pressure level.

[0098] In this embodiment, it should be noted that since the sound is heard by the ear of the person, and the actual distance measured by infrared is the distance from the point on the target to be detected that is closest to the camera to the smart camera, when the target to be detected is in different human postures, it will affect the determination of the appropriate sound pressure level. The preset sound pressure level is the appropriate sound pressure level corresponding to the actual distance under the standard human posture, wherein the standard human posture can be set to a standing posture, and other human postures are non-standard human postures, such as a lying posture with the head facing the smart camera, a lying posture with the head away from the smart camera, and a squatting posture.

[0099] Specifically, according to the mapping relationship between the sound pressure level and the distance, the preset sound pressure level corresponding to the actual distance under the standard human posture is queried; the current human posture of the target to be detected is detected by the smart camera, and according to the mapping relationship between the current human posture and the volume compensation value, the sound pressure level compensation corresponding to the current human posture is queried; according to the sound pressure level compensation and the preset sound pressure level, the appropriate sound pressure level is determined. Therefore, the purpose of determining the appropriate sound pressure level of the target to be detected at the actual distance according to the current human posture of the target to be detected is achieved, the accuracy of determining the appropriate sound pressure level of the target to be detected at the actual distance is improved, and then the accuracy of volume compensation is improved.

[0100] The sound pressure level compensation may be a specific sound pressure level compensation value or a specific sound pressure level compensation coefficient, and the step of determining the appropriate sound pressure level based on the sound pressure level compensation and the preset sound pressure level includes:

[0101] When the sound pressure level compensation is a sound pressure level compensation value, the sound pressure level compensation and the preset sound pressure level are summed to obtain a suitable sound pressure level.

[0102] When the sound pressure level compensation is a sound pressure level compensation coefficient, the sound pressure level compensation and the preset sound pressure level are multiplied to obtain a suitable sound pressure level.

[0103] Step A20, calculating the difference between the current sound pressure level and the appropriate sound pressure level to obtain a sound pressure level difference;

[0104] Step A30: Calculate the volume compensation value according to the sound pressure level difference.

[0105] In this embodiment, specifically, the difference between the current sound pressure level and the appropriate sound pressure level is calculated to obtain the sound pressure level difference, and the ratio between the sound pressure level difference and a preset sound pressure level threshold is calculated to obtain a volume compensation value, wherein the preset sound pressure level threshold is a preset sound pressure level change value corresponding to a one-grid volume change.

[0106] Wherein, the step of calculating the volume compensation value according to the sound pressure level difference comprises:

[0107] Step A31, determining whether the sound pressure level difference is less than a preset sound pressure level threshold;

[0108] Step A32, if the sound pressure level difference is not less than the preset sound pressure level threshold, calculating the ratio between the sound pressure level difference and the preset sound pressure level threshold to obtain the volume compensation value;

[0109] Step A33: If the sound pressure level difference is less than the preset sound pressure level threshold, then the volume compensation is not performed on the sound system in the smart camera.

[0110] In this embodiment, specifically, it is determined whether the sound pressure level difference is less than a preset sound pressure level threshold value; if the sound pressure level difference is not less than the preset sound pressure level threshold value, it is proved that the sound pressure level difference is not less than the sound pressure level change value required for a one-grid change in volume, and then the ratio between the sound pressure level difference and the preset sound pressure level threshold value is calculated to obtain the volume compensation value; if the sound pressure level difference is less than the preset sound pressure level threshold value, it is proved that the sound pressure level difference is less than the sound pressure level change value required for a one-grid change in volume, and then there is no need to perform volume compensation on the sound system in the smart camera.

[0111] Step S30: performing volume compensation on the sound system in the smart camera according to the volume compensation value.

[0112] In this embodiment, specifically, the volume compensation value is compensated to the microphone and speaker of the sound system in the smart camera.

[0113] The embodiments of the present application provide a volume compensation optimization method, device, electronic device and readable storage medium, that is, detecting the actual distance between the smart camera and the target to be detected, and obtaining the current sound pressure level of the sound system in the smart camera, and then determining the volume compensation value according to the current sound pressure level and the actual distance, so as to achieve the determination of the volume compensation value required for the current volume according to the current volume and the actual distance, and then performing volume compensation on the sound system in the smart camera according to the volume compensation value, so as to achieve the purpose of performing volume compensation on the current sound pressure level emitted by the sound system in the smart camera according to the actual distance between the target to be detected and the smart camera, so that the sound emitted by the sound system in the smart camera matches the actual distance, so as to provide a better listening effect for the target to be detected, and overcome the technical defect that when the user is close to the camera, the sound heard is usually louder, and when the user is far away from the smart camera, the sound heard is usually smaller, so as to improve the listening effect of the sound system of the smart camera.

[0114] Embodiment 2

[0115] Further, refer to Figure 2 Based on the first embodiment of the present application, in another embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. On this basis, the step of detecting the actual distance between the smart camera and the target to be detected includes:

[0116] Step S11, measuring the distance between the smart camera and the target to be detected by an infrared device on the smart camera to obtain a measured distance;

[0117] In this embodiment, the infrared device on the smart camera transmits infrared rays to the target to be detected, and receives the infrared rays reflected by the target to be detected, thereby determining the time interval from the infrared device transmitting the infrared rays to receiving the infrared rays reflected by the target to be detected. Based on the time interval, the distance between the smart camera and the target to be detected is calculated to obtain the measured distance.

[0118] Step S12, detecting the current human posture of the target to be detected by the smart camera, and determining a distance compensation value according to the current human posture;

[0119] In this embodiment, it should be noted that since the sound is listened to by the ears of a person, and the actual distance measured by infrared is the distance from the point on the target to be detected that is closest to the camera to the smart camera, there will be a certain error when volume compensation is performed directly based on the distance measured by the infrared device.

[0120] The current human posture of the target to be detected is detected by the smart camera, and the distance compensation value is determined according to the current human posture. Specifically, the current human posture of the target to be detected is detected by the smart camera. If the current human posture is consistent with the standard human posture, the measured distance is directly used as the actual distance. If the current human posture is inconsistent with the standard human posture, the distance compensation value corresponding to the current human posture is queried according to the mapping relationship between human posture and distance compensation, wherein the standard human posture is a human posture in which the human head is not far away from the camera, for example, a standing posture or a lying posture with the head facing the camera, etc., and the non-standard human posture is a human posture in which the human head is far away from the camera, for example, a lying posture with the head far away from the camera, etc.

[0121] Wherein, the step of detecting the current human posture of the target to be detected by the smart camera includes:

[0122] Step S121, obtaining an image of the target to be detected taken by the smart camera;

[0123] In this embodiment, the target to be detected is photographed by the smart camera to obtain a photographed image.

[0124] Step S122, classifying the captured image according to a preset image classification model to obtain an image classification label;

[0125] In this embodiment, it should be noted that the preset image classification model is a machine learning model for classifying human posture images, and the preset image classification model may be a convolutional neural network model. The preset image classification model may be a multi-classification model.

[0126] Step S123, determining the current human body posture according to the image classification label.

[0127] In this embodiment, according to a preset image classification model, feature extraction is performed on the pixel matrix corresponding to the captured image to obtain captured image features, and then the captured image features are fully connected to obtain an image classification label; the human body posture corresponding to the image classification label is used as the current human body posture.

[0128] Step A13, calculating the actual distance according to the distance compensation value and the measured distance.

[0129] In this embodiment, it should be noted that the distance compensation value may be a specific distance value or a compensation coefficient.

[0130] The actual distance is calculated according to the distance compensation value and the measured distance. Specifically, the distance compensation value and the measured distance are summed to obtain the actual distance; or the distance compensation value and the measurement matrix are multiplied to obtain the actual distance.

[0131] The embodiment of the present application provides a method for measuring the actual distance between a target to be detected and a smart camera based on human body posture, wherein the distance between the smart camera and the target to be detected is measured by an infrared device on the smart camera to obtain a measured distance; the current human body posture of the target to be detected is detected by the smart camera, and a distance compensation value is determined based on the current human body posture; the actual distance is calculated based on the distance compensation value and the measured distance. Considering that the sound is heard by human ears, the distance measured by the infrared device is compensated by detecting the human body posture of the target to be detected, so the accuracy of measuring the distance between the target to be detected and the smart camera is improved, and the distance measurement error for volume compensation caused by human body posture is eliminated, so the accuracy of volume compensation is improved.
