Step S110, controlling a camera to collect an object image of a target object, and performing temperature measurement position estimation processing based on the object image to obtain an estimated temperature measurement position of the target object;

The camera can capture an object image of the target object in real time, i.e., an image of the target object in a specific environment. The camera can be controlled to follow the object image of the shooting target object by carrying out object detection on the object image acquired in real time so as to ensure that the face part of the target object is included in the object image.
The temperature measurement position estimation processing is carried out based on the real-time collected object images (usually comprising at least 2 images), so that the estimated temperature measurement position of the target object can be obtained, and the estimated temperature measurement position is the estimated position for carrying out temperature measurement.
After the temperature pre-estimated position is obtained, the temperature measuring area of the target temperature measuring sensor is controlled to pre-rotate to the pre-estimated temperature measuring position, and the efficiency and the positioning accuracy of subsequently further controlling the positioning and temperature measuring position can be improved. And meanwhile, the real-time forehead position of the target object can be determined by carrying out real-time forehead detection according to the object image, and the real-time forehead position is the real-time forehead position.
Furthermore, the target temperature measuring sensor is controlled to rotate according to the newly determined real-time forehead position and the estimated temperature measuring position, so that the temperature measuring area of the target temperature measuring sensor can be accurately, efficiently and remotely controlled to be positioned to the forehead position of the target object in real time, and the temperature data of the forehead position of the target object is measured. The temperature data, i.e. the sensor temperature signal data, is converted to determine the final measured temperature.

In an example, the preset position estimation model may be a model based on a specific empirical formula, and the acquired time point and head position data may be calculated based on the specific empirical formula, that is, the estimated temperature measurement position may be obtained by performing estimation processing on the temperature measurement position.

In an example, the field angle FOV of the infrared temperature measurement sensor is less than 5 degrees, and compared with the case that the field angle FOV is greater than 5 degrees, the measurement distance can be increased, and the measurement distance and the measurement precision can be further increased as a whole by combining the temperature measurement scheme of the present application.

And setting a corresponding target temperature measuring area for each preset position range, and determining the corresponding target temperature measuring area based on the position range of the estimated temperature measuring position. Therefore, the target temperature region can be determined efficiently and accurately.

In step S140, the subject temperature of the target subject is determined according to the temperature data of the forehead region.
The temperature data, i.e. the sensor temperature signal data, is converted to determine the final measured temperature.
In one embodiment, the method further comprises: and transmitting the measured temperature to the camera so that the camera displays a visible light image of the target object and target temperature information on target equipment according to the measured temperature.
