Application method of polarized lens in monitoring camera protection cover

Abstract

The invention relates to an application method of a polarized lens in a monitoring camera protection cover. The polarized lens is adhered to one side near the inner side of transparent glass on the monitoring camera protection cover in a vacuumizing way, or the polarized lens is fixed on one side near the inner side of the transparent glass of the monitoring camera protection cover; the polarized lens is positioned between the transparent glass and an optical lens of a monitoring camera; the plane of the polarized lens is parallel to the plane of the transparent glass; the outer side of the transparent glass of the monitoring camera protection cover is used for preventing dust; the polarized lens arranged in a cavity of the monitoring camera protection cover is used for carrying out directional processing on the entering image lights; and only a part of image lights, the polarization direction of which is same as the direction of a light transmitting axis of the polarized lens, can enter the parts of the optical lens and a camera, and other directions of polarized lights with various angles can be adsorbed. By utilizing the application method disclosed by the invention, the image of the monitoring camera of the protection cover applying the method has more saturated color and more distinct picture so that the imaging effect of the camera can be remarkably promoted.

Description

technical field [0001] The invention relates to an application method of a polarizing lens in a protective cover of a monitoring camera. The method utilizes the polarizing lens to improve the light direction of scene images, so that the imaging effect of the monitoring camera installed in the protective cover is significantly improved. Background technique [0002] Many reflected lights are harmful in photography. For example, the reflected light on the glass surface prevents us from photographing 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. [0003] Traditionally, ...

Problems solved by technology

[0003] Traditionally, the images collected by the surveillance cameras installed in the protective cover of surveillance cameras are natural images that directly enter the surveillance cameras through the optical lens. Due to the influence of multi-angle polarization glare, the effect of surveillance images is often unclear
