Abstract

The utility model relates to a monitoring camera equipped with a polarized lens, characterized in that the polarized lens is pasted or fixed on the inner side of a dustproof perspective glass of the camera equipped with a dustproof perspective window, is located between the dustproof perspective glass and an optical lens, and is parallel with the plane of the perspective glass. By utilizing the polarized lens to improve the directivities of scenery image rays, only the part of which the polarization direction is in the same direction with the light transmittance shaft direction of the polarized lens in the image rays can enter into the optical lens and a subsequent camera circuit part, so that the colors of the obtained monitoring images are more saturated, the pictures are clearer, and the imaging effect of the monitoring camera is improved obviously.

Description

The rig camera of polarized lenses is installed

Technical field

The utility model relates to a kind of polarized lenses that utilizes and improves scenery image radiation direction property, can promote the rig camera that polarized lenses is installed of keeping watch on image effect.

Background technology

Many polarized lights are harmful in photography, 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 the camera circuitry part 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 follow-up camera circuitry part in the image light; The polarization dazzle of the multiple angles of other direction then is absorbed, and has reduced the interference of multiple angles polarized light, and the supervision image color that obtains is more saturated; Picture is more clear, the rig camera 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 rig camera 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 video camera that has dustproof perspective window, polarized lenses between dustproof combining glass and optical lens and with the combining glass plane parallel.

In polarized lenses and dustproof combining glass be housed the fixing glass fastener be fixed on the camera housing 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 video camera 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 follow-up camera circuitry part in the image light, the polarization dazzle of the multiple angles of other direction then is absorbed, and has reduced the interference of multi-angle polarized light; The supervision image color that obtains is more saturated; Picture is more clear, and the video camera imaging effect is obviously promoted, and places the video camera protection chamber of the dustproof perspective of band window inner polarized lenses simultaneously; Protect polarized lenses effectively, improved the serviceable life and the validity of polarized lenses.Utilize the such TV monitoring and controlling video camera of the utility model 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 rig camera of this band polarized lenses, use also produces effect under non-visible infrared light.

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, the 2-combining glass that prevents dust, 3-O-ring seal, 4-fixing glass fastener, 5-camera housing, 6-optical lens, 7-camera mount.

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 rig camera that polarized lenses is installed; Lean on lining one side to paste or be fixed with polarized lenses 1 at the dustproof combining glass 2 of the video camera that has dustproof perspective window, polarized lenses 1 between dustproof combining glass 2 and optical lens 6 and with dustproof combining glass 2 plane parallel.

Described a kind of rig camera that polarized lenses is installed, in polarized lenses 1 and dustproof combining glass 2 be housed fixing glass fastener 4 be fixed on the camera housing 5 through set bolt, forms one and protects the chamber.Simultaneously between the outer rim of dustproof combining glass 2 and fixing glass fastener 4, O-ring seal 3 is housed, makes polarized lenses 1 be positioned at before the optical lens 6 like this, only let the light of a direction through arriving optical lens 6 and subsequent conditioning circuit part.

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 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; Polarized lenses 1 is placed the inside, protection chamber of the video camera of the dustproof perspective of band window; Protect polarized lenses 1 effectively, improved the serviceable life and the validity of polarized lenses 1.Utilize the such TV monitoring and controlling video camera of the utility model 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 rig camera of this band polarized lenses 1, use also produces effect under non-visible infrared light.

Claims

1. rig camera 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 video camera that has dustproof perspective window, polarized lenses between dustproof combining glass and optical lens and with the combining glass plane parallel.

2. the rig camera 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 housing through set bolt.
