The method can be applied to a terminal or a server, and the embodiment is applied to terminal illustration. The body temperature measurement method of the intelligent watch specifically comprises the following steps:
s110: triggering a shooting start instruction by acquiring a first action of the watch body pointing to a human face;
the watch body is not provided with a first action for pointing to the face, but is provided with a first action for triggering a shooting start instruction, so that whether a user has an intention to measure the temperature is identified, and if the user has the intention to measure the temperature, a specific action for preparing to measure the temperature is necessarily performed.
The step of obtaining the first action of pointing the watch body to the face may include: acquiring a first motion trail of the equipment through an acceleration sensor and a gyroscope; detecting whether the first motion track accords with a first preset motion, wherein the first preset motion is wrist lifting motion of continuously ascending the watch body and/or wrist turning motion of the watch body with a turning angle exceeding 45 degrees; the calculated initial position of the turning angle of the wrist turning action is that the display screen of the watch body is positioned on the horizontal plane, and the range of the turning angle is usually 45-90 degrees. And if the first motion trail accords with the first preset motion, taking the first motion trail which accords with the first preset motion as a first motion of pointing the watch body to the face.
The first action of pointing the watch body to the face may be specifically embodied, which indicates that the user points or faces the intelligent wearable device to the face, and the detection action or the detection result of the user pointing or faces the intelligent wearable device to the face may be detected through the sensor, for example, the first action of pointing the watch body to the face is obtained as: and an operation in which the carbon dioxide concentration value obtained by the carbon dioxide concentration detector exceeds the CO2 concentration threshold value.
The first action of pointing to the face through the watch body can identify that the user has the intention of measuring the body temperature, when the user has the intention of measuring the body temperature, the temperature measuring instruction cannot be directly triggered and the temperature measuring action is started, because the temperature measuring condition is not fully considered when the temperature measuring action is started, misalignment of the forehead, such as alignment of the forehead side edge, eyebrow area, even the area of the face, the cheek, the nose and the like, is easy, the condition that the automatic starting time of the body temperature is too early or too late is easy to occur, and the problem that the result of the body temperature measurement is inaccurate is caused under the conditions.

s220: the camera shooting starting instruction controls a camera shooting device on the watch body to continuously acquire face image information, and whether the face image information comprises forehead information or not is analyzed;
the step of analyzing whether the face image information includes forehead information includes:

In the second embodiment, a more accurate temperature measurement position is screened through the identification of the unoccluded forehead of the face image information, a more accurate temperature measurement time is obtained, and a more accurate temperature measurement result is realized, however, a more strict temperature measurement condition and a more accurate temperature measurement result also bring a certain negative effect, namely when the temperature measurement condition is more complex, the temperature measurement condition is difficult to trigger, so that a user starts the temperature measurement action for many times without triggering the temperature measurement instruction, and the problem that the triggering of the temperature measurement instruction is difficult to cause the action waste of the user and the reduction of the user experience is caused.
As shown in fig. 3, in order to solve the above technical problem and realize more accurate and intelligent body temperature measurement triggering, the embodiment provides a body temperature measurement method of a smart watch, which includes the following steps:

S330: if the human face image information comprises forehead information, the body temperature identification area falls into the unoccluded forehead through the infrared temperature measurement angle modulation device, and a temperature measurement instruction of the infrared body temperature detection device is triggered through a second action of acquiring the wrist watch body pointing to the forehead.
The step of obtaining the second action of pointing the watch body to the forehead comprises the following steps: analyzing forehead information in the face image information; judging whether a body temperature identification area of the infrared body temperature detection device falls into a forehead area; if the body temperature identification area falls into the forehead area, acquiring a body temperature identification distance between the infrared body temperature detection device and the forehead; and if the body temperature identification distance is within the preset distance identification threshold range, judging that a second action of pointing the watch body to the forehead exists.
