Specifically, face image collection is performed by starting the camera on the smart thermometer 1 , and the face image is calibrated through the viewfinder frame on the display screen of the smart thermometer 1 . Wherein, the viewfinder frame refers to a frame for displaying a face image captured by a camera. In the embodiment of the present invention, in order to quickly and accurately align the human face at a suitable position, the face image is calibrated through a viewfinder frame with a fixed position on the display screen, that is, the size and position of the display frame will not change with the movement or The position of the intelligent thermometer 1 moves and changes. The user calibrates the face image through the viewfinder frame, so that the position of the facial contour of the face in the viewfinder frame complies with the preset acquisition standard.

Optionally, for aligning face images, the step S201 specifically includes:

A1. Perform face recognition, and determine the forehead center position of the face.

A2. According to the distance between the forehead center position of the human face and the four edges of the viewfinder frame, the position of the human face image is adjusted according to the preset acquisition standard.

Specifically, use face recognition technology to identify the contour of the face in the viewfinder frame, and calculate the center position of the forehead of the above-mentioned face. Adjust the position of the face image, when the central position of the forehead overlaps with the central position of the forehead in the preset acquisition standard, so that the temperature measuring device in the intelligent thermometer 1 is aligned with the center of the forehead of the human face. It should be noted that the user may be reminded by marking with a cursor, or reminded by voice, vibration or ringtones that the user's forehead has been aligned, which is not limited here.

Step S202, when the face image in the viewfinder meets the preset collection standard, send a temperature measurement command to detect the body temperature to obtain body temperature information.

In the embodiment of the present invention, when the face image in the viewfinder meets the preset acquisition standard, the user is reminded that the face to be detected has been aligned through vibration or ringtone or a combination of vibration and ringtone, and a temperature measurement command is sent to monitor the body temperature.
