The invention relates to a human body temperature measurement method. The method comprises the steps: acquiring a frame of image from a video shot by a video camera to serve as a to-be-detected image;detecting whether the to-be-detected image contains a human face or not by utilizing a human face detection algorithm, if the to-be-detected image contains the human face, acquiring position information of the human face in the current to-be-detected image, and mapping the position information of the human face into an infrared temperature measurement module, otherwise, directly acquiring a nextframe of image; acquiring full-array temperature data in the face contour from the infrared temperature measurement module; according to the full-array temperature data in the human face contour, calculating a human body forehead temperature value through a human face temperature measurement algorithm, wherein the human face temperature measurement algorithm is used for eliminating interference ofabnormal temperature, external environment temperature and equipment heating temperature; and calculating the human body forehead temperature value through a conversion formula to obtain a human bodytemperature value. In combination with the video camera, a face detection algorithm in a video is utilized, a face is detected firstly, and then infrared temperature measurement is carried out, so wrong data can be effectively avoided, and the effectiveness of a temperature value and the accuracy of body temperature detection are ensured.
Description
technical field [0001] The invention relates to the technical field of infrared temperature measurement, in particular to a human body temperature measurement method. Background technique [0002] Temperature measurement products are widely used in people's lives. Many public places have installed human body temperature measurement equipment for real-time monitoring of human body temperature and timely screening for people with high body temperature. However, traditional infrared temperature measurement equipment has poor temperature measurement accuracy and anti-interference performance, which leads to mismeasurement, inaccurate measurement, and interference from heat sources and sunlight. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a human body temperature measurement method with higher measurement accuracy. [0004] For realizing the purpose of the present invention, the present invention adopts following technic...
