Specific embodiment
It elaborates with reference to the accompanying drawing to specific embodiment provided by the invention.
Appended drawing reference involved in attached drawing and component part are as follows:
0. input unit
1. 2. system program of detection device
3. 4. mechanical arm of infrared camera
5. output device
Before illustrating the present invention, first illustrate the cardinal principle and thought of the present invention herein:
Image is the image that objective scenery is formed in human brain, is the most important information source of the mankind, it is by various sights
Examining system is obtained from objective world, has intuitive and Comprehensible.With computer technology, multimedia technology, artificial intelligence
Can technology rapid development, image procossing changes people's lives mode and the means of production just significantly, for example people can be with
By means of the License Plate Automatic Recognition System in the scenery of the image processing techniques appreciation moon, traffic administration, the meter in robot field
Calculation machine vision etc. all be unable to do without video procession technology in such applications.Image procossing refers to computer to image
It is handled, highlights exchanging of carrying out between image and image, main target is processed to image to improve image
Visual effect and lay foundation for the image recognition in later period.Image recognition be image is handled using computer, analyze and
Understand, to identify the target of various different modes and to the technology of picture.
In nature, the object that all temperature are higher than absolute zero is all ceaselessly issuing infra-red radiation to surrounding space
Energy.The size of the infrared energy of object and its there is very close pass with its surface temperature by the distribution of wavelength
System.Infrared thermal imaging technique is the infra-red radiation issued by infrared sensor reception positioned at the measurand of certain distance, then
The thermal image of target is transformed by signal processing system.The heat distribution of object is presented in it in a manner of visual image, and
It is shown in the form of gray scale or pseudo-colours, to obtain the Temperature Distribution field of measurand.Infrared thermal imaging is due to not light
According to the influence of, environmental factors such as smog, high temperature, high pressure, extensive concern has been obtained.Infrared thermal imaging technique is easy to operate, nothing
Human factor influences, as a result objective, quantitative, intuitive, reproducible, hurtless measure contactless to patient, radiationless.
Near infrared spectrum is mainly since the anharmonicity of molecular vibration makes molecular vibration from ground state to when high energy order transition
It generates, what near infrared spectrum recorded is the frequency multiplication and sum of fundamental frequencies information of the fundamental vibration of single chemical bond in molecule, in near-infrared
In spectral region, the frequency multiplication and sum of fundamental frequencies of mainly hydric group X-H (X=C, N, O) vibration of measurement absorb.

Sore position is shown as sheet near-infrared absorption enhancement region under near infrared light；Pressure sore position continues to be pressurized, blood circulation
It cannot improve, venous return is obstructed, local venous congestion, and damage and necrosis occur for epidermis, the skin corium of skin, forms water
Blister and ulcer, will form granulation tissue between pressure sore position and health tissues, granulation tissue by the capillary of newborn thin-walled with
And the fibroblast of hyperplasia is constituted, granulation tissue is shown as near-infrared absorption enhancement region, pressure sore under near infrared light
Position is shown as cyclic annular near-infrared absorption enhancement region under near infrared light.And the superficial vein of normal skin is near infrared light
Strip near-infrared absorption enhancement region is shown as under irradiation.
