The Human Body Temperature Is Highly Accurate Measurement And Display Technology

Over the last decade, infrared thermal imaging technology has been developed quickly and matured gradually. This technology has been widely used in both military and civilian. In order to improve the accuracy of the human body temperature measurement and display the body temperature, a new data processing algorithm-bp neural network curve fitting algorithm and the pseudo-color processing algorithm are researched in the paper. Compared with the conventional temperature measurement, this temperature measurement system is higher accurate and more intuitive. This is very significance to the rapid body temperature measurement and real-time monitoring.At the first, the temperature calibration interface for the blackbody is made, through which the data of gray-temperature correspondence in the human body temperature range is obtained after demarcating the high-precision blackbody. Next, in order to realize the mathematical model and obtain the precise relationship of gray-temperature, the bp neural network curve fitting algorithm is researched. Finally, a temperature measurement interface for the real-time pseudo-color is made.In order to display body temperature in pseudo-color, many kinds of processing codes for body measurement and selection under different circumstances and different demands are compiled by researching on the pseudo-color processing algorithm.This paper is about a research for'High-precision Measurement and Display Technology of Body Temperature'.Its main purpose is to build a system of high precision and pseudo-color display for body temperature measurement. To achieve this goal, the best fitting mathematical relationship of gray-temperature is obtained by researching on a new data processing algorithm, and the body temperature is accurately and intuitively displayed by researching on pseudo-color processing algorithm.A pseudo-color temperature measurement system is built in this paper which realizes accurate measurement and pseudo-color display of the body temperature in the end. The system works well and the measurements are satisfactory after verifying in the experiment.
