Embodiment Construction

[0021] The existing common body temperature tester is a contact type body temperature tester, and there is also a non-contact infrared thermometer. The accuracy of the test is often not guaranteed. After experiments, the general error is greater than 1 degree Celsius. If a temperature test of a child with a fever of 38 degrees Celsius results in a normal temperature of 37 degrees Celsius, the test result is invalid and dangerous. At present, the main factors that affect the accuracy of infrared body temperature test are:

[0022] (1) When testing at a long distance, the infrared sensor needs to add a Fresnel lens to obtain the infrared light intensity of distant objects to achieve body temperature testing, and the focus of the Fresnel lens is determined, and only the test results near the focal length are is reliable. For example, when a Fresnel lens with a focal length of 50 cm is selected, the temperature of a point on the user's to-be-measured part (such as the forehead) ...

Abstract

The invention discloses a body temperature testing method and device. The method includes the steps of starting a camera and a first infrared thermodetector when receiving a temperature testing instruction, photographing a user through the camera to obtain an image, recognizing the image, determining the to-be-tested part of the user, obtaining the distance between the first infrared thermodetector and the user, controlling the first infrared thermodetector to measure the temperature of the to-be-tested part of the user when the distance is consistent with a preset distance threshold, and determining the body temperature value of the user or the range of the body temperature value of the user according to a preset rule and the measured temperature, wherein the preset distance threshold is set according to the focal length of a Fresnel lens of the first infrared thermodetector. The device comprises a device body, a microprocessor arranged on the device body, and the camera and the first infrared thermodetector connected with the microprocessor. By means of the method and device, the far-distance precise body temperature testing is realized, and actual requirements are met.

Description

technical field [0001] The present invention relates to a body temperature testing method and device. Background technique [0002] A common body temperature tester is a contact body temperature tester, which is used to test the temperature value of a user's armpit or oral cavity. However, the use of the contact body temperature tester is limited, for example, it is inconvenient for children to use. There is a non-contact infrared thermometer in the prior art, which can test the temperature of the user's forehead or ear, but the working distance of the current non-contact infrared thermometer is only about 3 cm, which cannot meet the requirements of long-distance temperature measurement. need. SUMMARY OF THE INVENTION [0003] The invention provides a body temperature testing method and device, which can meet the requirements of long-distance temperature measurement and improve the accuracy of body temperature testing. [0004] According to one aspect of the present inve...
