The specific embodiment
The invention provides a kind of method and system of human body infrared characteristic imaging, clearer, clear and definite for making purpose of the present invention, technical scheme and advantage, below develop simultaneously with reference to accompanying drawing that the present invention is described in more detail for embodiment.
In order to solve the existing problem that can not obtain effective heat radiation characteristic information in the human body infrared characteristic imaging process, the invention provides a kind of method and system of human body infrared characteristic imaging, the core concept of this method comprises: in 0.8 μ m～2.5 mu m wavebands human body is carried out imaging by computer system control infrared image imaging device, and the human body infrared picture data that obtains handled, show that by computer the full wave infrared image of output for doctor's observation analysis, has solved the problem of in 0.8 μ m～2.5 mu m wavebands human body not being carried out imaging in the prior art.
Fig. 1 is a system block diagram of the present invention, this system comprises infrared camera, computer system, wherein, infrared camera includes detector and control circuit, computer system links to each other with detector by the control circuit of infrared camera, human body is carried out continuous monitoring, and human body infrared picture data in 0.8 μ m～2.5 mu m wavebands is gathered in control, link to each other with image pick-up card in the computer system infrared picture data that infrared camera is obtained of the control circuit of infrared camera is sent to computer system by image pick-up card and is stored in the hard disk, analysis software by computer is handled the described infrared picture data that obtains, and shows the infrared image of the human body all band (i.e. 0.8 μ m～2.5 mu m waveband scopes) that output is required by the display that links to each other with computer; The function of computer system software of the present invention is the acquisition controlling that is used to finish image, the Flame Image Process of pictorial display and human body, because computer system is a technology well known to those skilled in the art to acquisition controlling and the pictorial display processing of finishing image, so do not do concrete narration.With regard to how the described infrared picture data that obtains handled below and be described.
Said system also comprises black matrix, and the effect of black matrix just provides the calibration of system, and its black matrix temperature when work is set at the observed temperature of skin surface; At first, measurement environment by Fig. 2, utilize computer control infrared image imaging device (as infrared camera or area array infrared detector) that human body is measured, the measurement data 1 that obtains is saved to hard disc of computer, utilize computer control infrared image imaging device (as infrared camera or area array infrared detector) that black matrix is measured then, the measurement data 2 that obtains also is saved to hard disc of computer, deduct described measurement data 2 (the black body radiation value of body surface temperature) with measurement data 1 and obtain new view data, the new data that to handle then show with the form of image, can be according to the radiant intensity difference, manifest with the color form of puppet, be convenient to doctor's observation analysis, wherein pseudo-color form manifests and is interpreted as: the normal demonstration is gray-scale map, be exactly according to its intensity display brightness according to the data of surveying, be for 100 (showing the brightest) to the maximum such as the A point value, B point minimum was 0 (showing the darkest); But the naked eyes resolution capability is poor, and 20 and 21 shown just being not easy are distinguished, so show that going up us can distinguish different values with colour, represent 20 such as redness, blue expression 21, and effect is more obvious than gray scale like this.
The purpose that the present invention deducts black body radiation is in order to obtain better display effect, because the infrared signal of human body equals (characteristic signal and equality of temperature black body radiation signal) addition, and because equality of temperature black body radiation signal is more intense, so characteristic signal can be buried in wherein; Infrared radiation measurement value such as human acupoint is 52, other skins are 51, difference is just not obvious like this, if but all deduct synthermal black body radiation value 50, be exactly the relation of twice between the infra-red radiation value of human acupoint and other skin infra-red radiation values so, so can obtain distinct image more.
Also comprise a measuring table according to Fig. 2 the present invention, its effect be in measurement with the thermal source in the environment or as the hot moxibustion thermal source that the Folium Artemisiae Argyi burning produces when stimulating the interference of human body is isolated; This measuring table can be a thermostatic chamber, and the people can stand wherein.This thermostatic chamber is except all adopting enclosed construction in the face of the one side of detection system.Concrete work process of the present invention comprises following step:
When step 1, measurement, human body is in the metastable environment, isolates extraneous interference by test platform;
Step 2, computer send working signal, and the infreared imaging device that links to each other with computer (as infrared camera or area array infrared detector) carries out infrared imaging to human body;
Step 3, in 0.8 μ m～2.5 mu m wavebands, human body is carried out imaging by computer system control infrared image imaging device;
View data is sent to computer system by image pick-up card and is stored in the hard disk in step 4,0.8 μ m～2.5 mu m wavebands that the infrared image imaging device is obtained;
Step 5, computer system software are handled being kept in 0.8 μ m～2.5 mu m wavebands in the computer view data, promptly deduct the black body radiation value, to generate new human body infrared image;
Step 6, show all band image in 0.8 μ m～2.5 mu m wavebands by display.
The present invention is owing to realized at 0.8 μ m～2.5 mu m wavebands human body being carried out infrared imaging by computer control infrared image imaging device, and infrared image handled, the human body infrared image of clear display has solved the problem that can not obtain effective heat radiation characteristic information in the prior art.
