And 102, acquiring the position of a target object in the preset area, wherein the position of the target object in the preset area is determined based on sound source positioning.
The electronic device may be a terminal, the terminal may include an infrared camera, the infrared temperature measurement data may be obtained by the infrared camera, and the terminal may further include a sound sensor, such as a microphone matrix, for sound source localization; or, the electronic device may be a server, and the server may receive the infrared temperature measurement data sent by the terminal and the position of the target object in the preset area sent by the terminal; alternatively, the electronic device may be a server, the server may include an infrared camera, the infrared thermometry data may be obtained by the infrared camera, and the server may further include a sound sensor, such as a microphone matrix, for sound source localization; and the like, the electronic device is not limited by the present embodiment.
In addition, the preset region may be determined based on a camera shooting range of the infrared camera, and the preset region may be a region within the camera shooting range of the infrared camera. For example, as shown in fig. 2, the imaging range of the infrared camera is: c1 to (180-c 1), the preset area may be the area between c1 to (180-c 1) with respect to the infrared camera.
It should be noted that the target object may be a human being, or may be a partial body region of a human being, such as a human face. The position of the target object within the preset area may be determined through sound source localization, for example, the position of the target object within the preset area may be determined through a controllable beam forming technique based on maximum output power, a high-resolution spectrogram estimation technique, or a sound source localization technique based on time-difference of arrival (TDE), which is not limited in this embodiment.
And 103, determining the temperature of the target object based on the infrared temperature measurement data and the position of the target object in the preset area.
The infrared temperature measurement data can comprise a plurality of pixel points corresponding to the preset area, and the target object can be determined according to the position of the target object in the preset area, so that the temperature of the target object can be determined based on the target pixel points; or, the infrared temperature measurement data may include temperatures of respective positions corresponding to the preset region, the temperatures of the respective positions may be calculated and obtained by the terminal according to a camera result of the infrared camera, and the temperature of the target object may be determined according to the position of the target object in the preset region.

The terminal can judge whether the target object is in the camera shooting range of the infrared camera through the angle of the sound source, and if the target object is in the camera shooting range of the infrared camera, the terminal can upload current infrared temperature measurement data to the server. And the server can calculate the temperature after receiving the infrared temperature measurement data uploaded by the terminal.

The server can also receive the sound source angle uploaded by the terminal and the volume corresponding to the collected human voice signal, so that the server can judge the interval where the human face is located in the infrared thermal imaging interface shot by the infrared camera according to the sound source angle and the volume. The server can calculate the infrared temperature measurement data in the interval to obtain the temperature value and the coordinates of the corresponding area. The server can send the calculated temperature and the coordinates of the corresponding area to the terminal, and the terminal can display the temperature of the corresponding area on a display interface, so that the tested person can obtain the body temperature of the tested person.

The voice endpoint detection of the collected voice signals may be that each frame of collected voice signals is sequentially input into a convolutional neural network model for voice endpoint detection to determine whether each frame of voice signals is a human voice signal; or, inputting each frame of collected sound signals into other neural network models for voice endpoint detection in sequence to determine whether each frame of sound signals is a human sound signal; alternatively, it may also be determined whether each frame of sound signal is a human sound signal according to the short-time energy and the short-time zero crossing rate of each frame of sound signal, and the like, which is not limited in this embodiment.
In the embodiment, the voice signals are detected through voice endpoint detection, the detected voice signals are subjected to sound source localization, and the non-voice signals can be prevented from being subjected to sound source localization, so that the workload of the electronic equipment can be reduced.

The attenuation coefficient a can be calculated as follows, and the attenuation coefficient can represent the attenuation of the sound wave in the current environment.
Where x denotes a distance from the sound source to the sound sensor, a0 denotes a sound pressure at the sound source, and a denotes a sound pressure collected by the sound sensor.
The attenuation coefficient a may be acquired by performing tests at a plurality of positions, and the average value of the sound level of the utterance when the user wakes up is acquired as a 0. After a and a0 are obtained, the distance between the sound sensor and the sound source can be calculated according to the sound pressure collected by the sound sensor. In a case where a sound source is a target object, a position of the target object within the preset area may be acquired based on a first angle of the target object with respect to the sound sensor and a distance between the target object and the sound sensor.

In this embodiment, the position of the target object in the preset area is obtained based on the first angle of the target object relative to the sound sensor and the distance between the target object and the sound sensor, so that the position of the target object in the preset area can be obtained without using a face recognition technology, and thus, a common camera is not required to obtain a video stream for face recognition, and the price of a microphone array for sound source localization is lower than that of a camera, so that the cost of an electronic device can be reduced.
