The utility model is work like this: allow person's to be measured face pass through the temperature detection actinal surface to infrared camera, the infrared radiation signal of person's to be measured infrared radiation signal that face gave off and the radiation of standard steady temperature radiation source institute is received by infrared camera together, the heat radiation of infrared camera during according to normal cell and improper cellular metabolism is poor, after the systematic analysis of machine special software is handled as calculated, on screen, demonstrate the distribution situation of the metabolic relatively intensity of human body cell with different colors, the degree that computing machine changes by a certain position of analysis to measure, differentiate the temperature at this position of human body, in order to overcome the drift that this temperature produces, improve the accuracy of measuring, computing machine receives the infrared radiation signal that standard steady temperature radiation source is given off simultaneously, because the temperature of standard steady temperature radiation source is a definite value, it for example is 34 ℃, computing machine just with it as reference point, the automatic accurate temperature that calculates each position of person's thermography to be measured.In the human body head infrared chart, can reflect just subregion wherein of medical science body temperature, as forehead, wing of nose both sides etc., the head temperature distributed intelligence of computing machine by collecting, according to statistics, extract the temperature information in forehead, wing of nose zone, again with standard steady temperature radiation source as reference temperature, it is revised, draw at last and show body temperature accurately.Though the thermographic variation of the background that variation of ambient temperature can cause because the standard steady temperature radiation source of introducing is proofreaied and correct the human body head infrared chart in real time by difference algorithm, obtains the infrared chart of true reflection body temperature.When background image changes, can the dynamic tracking change of background, do not influence the extraction of person under inspection's thermal map.When the person's of being picked up face appeared at the temperature detection mouth, background image can be eliminated fast by feature extraction by system within a second, correctly extract person under inspection's infrared chart.
Owing to adopted technique scheme, the utlity model has following advantage:
1. the thermometric time is less than 1 second, the temperature of human body fully in real time, fast five times than existing common thermal imaging system of its speed;
2. measuring accuracy is 0.1 ℃, than the high order of magnitude of common thermal imaging system;
3. when environment temperature changed within the specific limits, it all can stablize the temperature of measuring human body exactly, and repeated consistency of reading is better than each quasi-instrument;
4. the form imaging does not contact instrument, does not have any extraneous radiation source, meets requirements of green environmental protection;
5. show measured's body temperature timely, and have reliable prompt functions;
6. can in time store high hot person's facial Infrared Thermogram automatically, so that further analyze and diagnose.
