Abstract
The utility model relates to a monitoring camera protective cover provided with a polarized lens. An inner side of a dustproof perspective glass of the camera protective cover which is provided with a dustproof perspective window is pasted or fixed with the polarized lens. The polarized lens is arranged between the dustproof perspective glass of the protective cover and an optical lens of a monitoring camera, and is in parallel with the plane of the perspective glass. The polarized lens is used to improve the light directivity of a scenery image, only a part of the image light which has the same polarization direction and the optical axis direction of the polarized lens can enter into the optical lens and the monitoring camera, so the obtained color of a monitoring image is more saturated, and the picture is more clear, and consequently the imaging effect of the monitoring camera is improved obviously.
Description
Technical field
The utility model relates to a kind of polarized lenses that utilizes and improves scenery image radiation direction property, can promote the surveillance camera protective cover that polarized lenses is installed of keeping watch on image effect.
Background technology
Many polarized lights are harmful in shooting, like the reflected light of glass surface, make us take the thing less than the showcase the inside, and the reflected light of the water surface is taken less than the fish in the water us, and the reflected light on leaf surface makes leaf become white or the like.This be because, light is because the dazzle that the body surface reflex time has part to be produced multiple angles by polarization, it is unclear that contour of object is thickened, and also makes eye fatigue, discomfort.The traditional tv rig camera is that the nature image directly enters into video camera through optical lens, because the influence of dazzle is arranged, the monitoring image effect does not often see Chu.
The utility model content
For overcoming above-mentioned technical disadvantages; The utility model provides a kind of polarized lenses that utilizes to improve scenery image radiation direction property; Have only that polarization direction and polarized lenses light transmission shaft direction part in the same way can get into optical lens and rig camera in the image light, the polarization dazzle of the multiple angles of other direction then is absorbed, and the supervision image color that obtains is more saturated; Picture is more clear, the surveillance camera protective cover that polarized lenses is installed that the video camera imaging effect is obviously promoted.
The utility model solves the technical method that its technical matters adopted: a kind of surveillance camera protective cover that polarized lenses is installed; Wherein: lean on lining one side to paste or be fixed with polarized lenses at the dustproof combining glass of the camera protective cover that has dustproof perspective window, polarized lenses between dustproof combining glass and optical lens and with the combining glass plane parallel.
The further improvement of the utility model: the fixing glass fastener that polarized lenses and dustproof combining glass are housed in described is fixed on the camera protective cover shell through set bolt.
The beneficial effect of the utility model is: utilize polarized lenses to improve scenery image radiation direction property; Place the polarized lenses of the camera protective cover inner chamber of the dustproof perspective of band window that the image light that gets into is carried out directional process; Have only that polarization direction and polarized lenses light transmission shaft direction part in the same way can get into optical lens and rig camera in the image light; The polarization dazzle of the multiple angles of other direction then is absorbed, and the supervision image color that obtains is more saturated, and picture is more clear; The video camera imaging effect is obviously promoted; Place the camera protective cover of the dustproof perspective of band window inner polarized lenses simultaneously, protected polarized lenses effectively, improved the serviceable life and the validity of polarized lenses.Be placed on the video camera of using in the such TV monitoring and controlling camera protective cover of the utility model and can see the article in the show window clearly, the ripples that can see through surface reflection are seen the fish in the water, also can see through the people that vehicle glass is seen the car the inside clearly.The surveillance camera protective cover inside that has a polarized lenses 1 can pack into the optical lens 6 of different model and the rig camera 7 of different model, convenient and improved the range of application of polarized lenses 1.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the said polarized lenses of the utility model is installed in the structural drawing in the fixing glass fastener.
Among the figure: 1-polarized lenses, 2-combining glass, 3-O-ring seal, 4-fixing glass fastener, 5-surveillance camera protective cover shell, 6-optical lens, 7-rig camera
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Referring to Fig. 1 and Fig. 2; A kind of surveillance camera protective cover that polarized lenses is installed; Employing vacuumizes mode the dustproof combining glass 2 that polarized lenses 1 sticks on the camera protective cover is leaned on lining one side; Perhaps directly lean on lining one side to be superimposed the dustproof combining glass on polarized lenses 1 and the camera protective cover 2, dustproof combining glass 2 outsides are used for water proof and dust proof, place the image light of 1 pair of entering of polarized lenses of camera protective cover inner chamber to carry out directional process; Filter out the polarization dazzle of the multiple angles of other direction; Get into then in the light camera lens 6 of rig camera, the fixing glass fastener 4 that polarized lenses 1 and dustproof combining glass 2 are housed is fixed on the camera protective cover shell 5 through set bolt, between the outer rim of dustproof combining glass 2 and fixing glass fastener 4, O-ring seal 3 is housed simultaneously; Make polarized lenses 1 be positioned at before the optical lens 6 like this, only let the light of a direction pass through to arrive optical lens 6 and rig camera 7.
Before optical lens 6, utilize polarized lenses 1 reflective the and dazzle of multi-angle to be sponged; Have only the optical image of same direction can enter into the optical lens 6 of TV monitoring and controlling video camera; The color of the image that rig camera 7 obtains is more saturated; Picture is more clear, and the video camera imaging effect is obviously promoted.Being combined by combining glass 2, O-ring seal 3, fixing glass fastener 4 becoming dustproof perspective window; Place the camera protective cover of the dustproof perspective of band window inner polarized lenses 1; Protect polarized lenses 1 effectively, improved the serviceable life and the validity of polarized lenses 1.And can pack into the rig camera 7 of different model of the surveillance camera protective cover inside that polariscope is housed has improved the utilization rate of protective cover, has reduced cost.Be placed on the rig camera 7 that utilizes in the such TV monitoring and controlling camera protective cover of the utility model and can see the article in the show window clearly, the ripples that can see through surface reflection are seen the fish in the water, also can see through the people that vehicle glass is seen the car the inside clearly.
Claims (2)
1. surveillance camera protective cover that polarized lenses is installed; It is characterized in that: lean on lining one side to paste or be fixed with polarized lenses at the dustproof combining glass of the camera protective cover that has dustproof perspective window, polarized lenses between dustproof combining glass and optical lens and with the combining glass plane parallel.
2. the surveillance camera protective cover of polarized lenses is installed according to claim 1, it is characterized in that: in polarized lenses and dustproof combining glass be housed the fixing glass fastener be fixed on the camera protective cover shell through set bolt.
