Abstract
The utility model relates to a glimmering and coloured reconnaissance monitoring device. One end in a mirror shell body is provided with a light filter, the other end of the mirror shell body is provided with a CCD video camera, a lens is arranged between the light filter in the mirror shell body and the CCD video camera, and the CCD video camera is connected with an image collecting card which is arranged in a compatible computer through a video line. The utility model can utilize moonlight and starlight to obtain the image which has the same coloured effect in the sun, and can obtain a coloured image of which the information quantity is larger than that of a black and white image. The utility model has the advantages that the utility model can sense the spectral information of a target, can have good response to spectrums, cost is low, etc., and the utility model can be widely applied to security monitoring at night, the monitoring of the departments of police, armed police, etc. to an important target, and can be widely used for frontier defense suppressing smuggle on the sea, the research of rare animal habits, etc.
Description
Technical field
The utility model belongs to the optical instrument technical field, is specifically related to the colored reconnaissance and surveillance device of low-light.
Background technology
Aloft in the equipment of reconnaissance and surveillance, thermal infrared imaging device and microwave remote sensing device are nearly two, the 30 years two class remote sensing equipments with fine application prospect that grow up, because the thermal infrared imaging device mainly is to utilize the thermal radiation information of terrain object to come imaging, therefore can day and night obtain target data, be a kind of round-the-clock sensoring.The microwave remote sensing device be by terrain object reflection from the electromagnetic wave imaging of radar emission because it adopts the active detection method to the target launching electromagnetic wave, can also be a kind of round-the-clock remote sensing equipment therefore in overcast and rainy and imaging at night.
Above-mentioned two kinds of devices are because they belong to round-the-clock remote sensing equipment, so be widely used.Their major defect is: compares with visible light equipment, can't its spectral distribution of perception, and the cost height, particularly on Military Application, initiatively launching electromagnetic wave is very easily found by the enemy.Therefore developing the colored reconnaissance and surveillance device of a kind of round-the-clock visible light remedies the not enough of visible light and develops the advantage of visible light.
Obtaining of research coloured image, its purpose is to improve the information of image.Because human eye can distinguish that the progression of colored difference will be far longer than the progression of black and white difference, in order to make full use of the application of color in scouting and surveillance equipment, often utilize colour phhotograpy or colored synthetic method that multispectral image is handled, to obtain coloured image.But the illuminance of ccd fpa height that colour TV camera requires is usually greater than 1Lux, so almost can't use under low-light.Although the starlight colour TV camera also occurred, obtained the coloured image under the noctilucence, because it is long to obtain the piece image required time, can't use in a lot of dynamic case.Also there is the people once to propose color film is used for low illumination level photography, but, limited the development of this technology owing to do not possess real-time.Existing lll night vision equipment adopts image intensifier to obtain twilight image usually, and lll night vision extensively is used in military aspect.Once utilized the coupling of image intensifier and film to obtain black white image abroad.
Summary of the invention
Technical problem underlying to be solved in the utility model and solve the technical scheme that its technical matters adopts and be: the end in the mirror housing is provided with optical filter, the other end at the mirror housing is provided with ccd video camera, be provided with lens between optical filter and the ccd video camera in the mirror housing, ccd video camera is connected with image pick-up card in being arranged on compatible computer by video line.
The utility model utilizes moonlight and starlight acquisition with the image of the same color effect under the sunlight, can obtain the coloured image that many bigger than the monochrome image information amount.It has can perception target optical spectrum information, to the response of spectrum well, and advantage such as cost is low.Can be widely used in department's counterweight syllabus targets such as night safe supervision, public security, People's Armed Police and monitor, also can generally be used for marine frontier defense anti-smuggling, rare animal behavioral study or the like.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but the utility model is not limited to these embodiment.
In Fig. 1, the colored reconnaissance and surveillance device of the low-light of present embodiment is to be connected by optical filter 1, lens 2, ccd video camera 3, video line 4, image pick-up card 5, compatible computer 6, mirror housing 7 to constitute.
Left end in mirror housing 7 is equipped with optical filter 1, optical filter 1 has Red lightscreening plate, green color filter, blue color filter, be installed in the mirror housing 7 at three kinds of 1 optical filters 1 of choosing any one kind of them that filters during use, the right side of optical filter 1 is equipped with lens 2 in mirror housing 7.Right-hand member at mirror housing 7 is connected with ccd video camera 3 with the screw threads for fastening connector, and the model of ccd video camera 3 is WAT902H, and ccd video camera 3 is connected with image pick-up card 5 by video line 4, and image pick-up card 5 is installed on the compatible computer 6.The image of subject is after optical filter 1 filters and through lens 2, be imaged on the target surface of ccd video camera 3, ccd video camera 3 converts light signal to electric signal, video output terminals by ccd video camera 3 outputs to image pick-up card 5 by video line, signal by image pick-up card 5 collections, carry out the synthetic and spectral shift of coloured image through compatible computer 6, demonstrate image by display.
Principle of work of the present utility model is as follows:
With Red lightscreening plate 1 is the principle that example illustrates low-light level imaging.When Red lightscreening plate 1 is placed on illumination be 0.0003 ccd video camera 3 before the time, after the image of subject sees through wavelength and is Red lightscreening plate about 700nm by the center, only keep the red wave band part in its whole light, the image formation by rays of this wave band is on the target surface of ccd video camera 3, ccd video camera 3 converts light signal to electric signal, video output terminals by ccd video camera 3 outputs to image pick-up card 5 by video line 4 again, by image pick-up card 5 acquired signal, by display image is shown, obtained the image of the red wave band of captured scenery, with it as the red channel image in the composograph.Be changed to optical filter green and when blue, can obtain green and blue two channel image respectively, compatible computer 6 carries out the synthetic and spectral shift of coloured image then, obtain with sunlight under the same coloured image that utilizes moonlight, starlight acquisition.
