Application method of polarization lens in monitoring video camera

Abstract

The invention relates to an application method of a polarization lens in a monitoring video camera, which comprises the following steps: a vacuumizing way is adopted to paste the polarization lens at one side in dustproof perspective glass of the video camera provided with a dustproof perspective window, or the polarization lens is fixed at one side in the dustproof perspective glass of the video camera provided with the dustproof perspective window; the polarization lens is positioned between the dustproof perspective glass and an optical lens; the plane of the polarization is parallel to that of the dustproof perspective glass; the outer side of the dustproof perspective glass is used for preventing water and dust; the polarization lens arranged in a cavity of the video camera performing location processing on entered image rays; only the image rays with polarization directions being the same with a light transmitting shaft of the polarization lens can enter the optical lens and the follow-up circuit part of the video camera; and polarization lights with multiple angles in other directions are absorbed so as to reduce the interference of multi-angle polarization lights. Monitoring images obtained through the application method are more saturated in color and more clear in pictures, so that the imaging effect of the video camera is obviously improved.

Description

technical field [0001] The invention relates to an application method of a polarizing lens in a monitoring camera by using a polarizing lens to improve the light directionality of a scene image and to improve the effect of a monitoring image. Background technique [0002] Many reflected lights are harmful in photography, such as the reflected light on the surface of the glass, so that we cannot photograph the things inside the glass window, the reflected light on the water surface prevents us from photographing the fish in the water, and the reflected light on the surface of the leaves makes the leaves become white and so on. This is because when the light is partially polarized due to the reflection from the surface of the object, it will produce glare from various angles, which will blur the outline of the object and make the eyes tired and uncomfortable.

Problems solved by technology

[0003] In traditional TV surveillance cameras, the natural image directly enters the camera circuit part through the optical lens. Due to the influence of glare, the effect of the surveillance picture is often unclear.
