Abstract
The invention discloses a helmet with infrared photographing and displaying functions. A protective cap, an infrared camera, a video processing circuit, a display screen and an optical image enlarging system are arranged on the helmet; the infrared camera is connected with the video signal input end of the video processing circuit, the display screen is connected with the video signal output end of the video processing circuit, and the optical image enlarging system is arranged between the display screen and the protective cap. The images from the display screen are enlarged by the optical system and projected to the protective cap, and then reflected to human eyes. The inventive helmet is used for searching persons and observing environment by fire fighters and public security personnel under smoky and dark environments.
Description
Technical field
The present invention relates to a kind of helmet, especially have the helmet of infrared photography and Presentation Function.
Background technology
In fire-fighting work, how safe escape is a most important research topic to personnel.The subject matter that wherein relates to is that in fire, because factors such as smog, survivor or fire fighter can't see the scene of interior of building clearly at all.The fireman can in time find life entity under smog, dark surrounds, be rescue fire disaster escaping person's most critical factor.Therefore inventing a kind of can the equipment of clear observation surrounding environment be very important under dark surrounds.
Summary of the invention
The purpose of this invention is to provide a kind of helmet with infrared photography and Presentation Function, to be implemented under smog or the dark surrounds, human eye can clearly be observed surroundings.
For reaching above-mentioned purpose, the technical solution that the present invention takes is: the optical system of installing protective cover, thermal camera, video processing circuits, display screen and enlarged image on the helmet, thermal camera links to each other with the video signal input terminal of video processing circuits, display screen links to each other with the VT of video processing circuits, display image is amplified project the optical system of protective cover between display screen and protective cover.
Above-mentioned thermal camera can install in the top, dead ahead of the helmet or the side of the helmet.For preventing the damage of high temperature and bump, can the video camera protective cover be installed in the thermal camera outside to video camera.
During use, the scene that thermal camera is taken is presented at display screen through video processing circuits, and display image projects protective cover by the optical system amplification, reflexes to human eye through protective cover again.
Beneficial effect of the present invention is:
The present invention adopts thermal camera, display screen and optical system and fireman's faceplate to combine, constituted the helmet with infrared photography and Presentation Function, because smog etc. are transparent to infrared light, therefore can make fireman or other staff under smog, dark surrounds, the scene around clearly observing.Because image that shows and extraneous scene overlap, therefore the definite particular location of perception external object, in addition by to the processing of infrared image, surface temperature that can recognition object is for the fireman correctly judges life entity, prevents to contact high temp objects help is provided.This helmet can be used for the fire fighter, occasion such as the personnel search and rescue of public security officer under smog, dark surrounds, environment perception.
Description of drawings
Fig. 1 is a structural principle schematic diagram of the present invention;
Fig. 2 is the theory diagram of video processing circuits among the present invention;
Fig. 3 takes direction for video camera among the present invention and the display image position concerns schematic diagram.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1; the helmet with infrared photography and Presentation Function of the present invention comprises the helmet 1, thermal camera 2, protective cover 3, video processing circuits 4, display screen 5 and optical system 6; in the illustrated example; thermal camera 2 is placed in the top, dead ahead of the helmet 1; the outside is equipped with video camera protective cover 8; cover whole thermal camera, the video camera protective cover adopts the material of infrared transparent to make.Thermal camera 2 links to each other with the video signal input terminal of video processing circuits 4, display screen 5 links to each other with the VT of video processing circuits 4, optical system 6 is between display screen and protective cover, display image projects protective cover 3 by optical system 6 amplifications, reflexes to human eye 7 through protective cover 3 again.
Above-mentioned video processing circuits 4 comprises central processing unit (CPU) 42 and A/D conversion chip 41 that is connected with central processing unit 42 and D/A conversion chip 43 as shown in Figure 2.
The detecting band of thermal camera can be any one or their combination in 0.8-3um, 3-5um, three infrared wavelength sections of 8-12um.Thermal camera is taken the infrared image that obtains and is delivered in the video processing circuits 4, by A/D conversion chip 41 Infrared Video Signal of importing from thermal camera is carried out analog-to-digital conversion, becomes 8 data signal, sends central processing unit 42 to.42 pairs of vision signals of central processing unit are discerned and are handled.Mark such as carrying out temperature, and the data signal of mark is superimposed upon on the original video signal the different gray scales in the vision signal.Through the later data signal process D/A conversion chip 43 of video superimpose, be reduced to video analog signal.Video analog signal is input to display screen 5 and shows.
To the temperature of infrared image mark is that principle according to black body radiation realizes.According to Planck's law of radiation, the black matrix of unit are in unit interval, unit solid angle and the energy that gives off in the unit wavelength interval be
Wherein λ is a radiation wavelength, and T is a black matrix absolute temperature, and h is a Planck's constant, and K is a Boltzmann constant, and c is the light velocity, and v is a frequency of light wave.And B (λ T) is exactly the captured gradation of image of thermal camera 2.Because the detection wavelength of video camera is known, thus can calculate certain gray scale in the image the approximation of temperature of corresponding object.
Image on the display screen 5 amplifies by optical system 6.Display screen and optical system can be installed in the protective cover inboard, to prevent damage.Optical system 6 can adopt glass lens or plastic lens.Eyeglass can one or morely be formed.Optical system 6 zooms into a virtual image to the image on the display screen 5, and by protective cover 3 reflections, reverberation enters human eye.
During use, under smog, dark surrounds, the scene around human eye is difficult for seeing clearly.The scene of taking by thermal camera is presented at display screen through video processing circuits, display image projects protective cover by the optical system amplification, reflex to human eye through protective cover again, reflection image is the virtual image 9, and the position of the virtual image is in the protective cover outside (as shown in Figure 3).Make the lens ratio of thermal camera photographic images identical, can make the virtual image identical like this with the actual object size with the optical system multiplying power that shows usefulness.The angle of thermal camera 2 and optical system 6 can be regulated with the mechanical fixation mechanism of the helmet by them, makes that to take the virtual image direction that direction and human eye see after by the protective cover reflection identical, and makes the virtual image and the coincidence of outside actual object.
The helmet 1 can adopt metal or fire-resistant organic material to make, and its effect is that the protection head is not clashed into by exterior object.Protective cover 3 shapes are curved surfaces, encase people's face, make the extraneous directly contact of people's face discord.Protective cover can adopt high temperature resistant and crash-proof glass or transparent organic material making, and like this, under non-smog, non-dark surrounds, human eye can be seen outside scene by protective cover 3.
