Apparatus and method for measuring body temperature of a human body
View Patent ↗The invention relates to an apparatus for measuring the human body temperature. It comprises of an infrared temperature sensor for performing temperature sampling on a plurality M×N of sampling points, M≥3, N≥3. The temperatures of the sampling points with temperatures within the effective temperature range of the human body are averaged to obtain the body temperature of the human body. By collecting the temperatures of a plurality of sampling points of the measured object, the invention effectively avoids the errors that measurement of single point may produce (as may be caused by factors such as the environment); by screening for temperatures within the effective temperature range of the human body, the invention effectively avoids errors or interference produced by factors such as clothing or the environment. The improved accuracy and real-time measurement of body temperature bring convenience to people's lives.
1. An apparatus for measuring human body temperature, comprising:
a camera and an infrared temperature sensor arranged within a single unit;
wherein the infrared temperature sensor has an effective temperature collection distance of 1.5 meters or more and collects temperature information at each of 64 sampling points distributed as a rectangular matrix within the imaging area of the camera;
the apparatus being configured to calculate a measured human body temperature from the temperature information of sampling points which have temperature information that falls within an effective human body temperature range, and
the apparatus being configured to transmit a camera image and the measured human body temperature to a remote device in real-time.
2. The apparatus for measuring human body temperature of claim 1 , wherein the apparatus is configured to use a temperature range of 35° C. to 42° C. as the effective human body temperature range.
3. A method for measuring the body temperature of a human being, comprising:
providing a camera and an infrared temperature sensor within a single unit, the infrared temperature sensor having 64 sampling points distributed as a rectangular matrix in the camera imaging area and an effective temperature collection distance of 1.5 meters or more;
collecting, using the infrared temperature sensor, temperature information at each of 64 sampling points distributed as a rectangular matrix;
determining whether the temperature information of each sampling point falls into an effective human body temperature range,
determining a measured human body temperature using only the temperature information from sampling points which fall within the effective human body temperature range, and
transmitting a camera image and the measured human body temperature to a remote device in real-time.
4. The method of measuring the body temperature of claim 3 , wherein a temperature range of 35° C. to 42° C. is used as the effective human body temperature range.
