Intelligent anti-dazzle system

Abstract

The invention relates to the technical field of anti-dazzle, and discloses an intelligent anti-dazzle system which comprises a controller, a first camera used for shooting a scene image in front of a vehicle in real time, a second camera used for shooting a human eye image of a driver and an anti-dazzle film. The anti-dazzle film comprises a substrate and a plurality of electrically-controlled shading units arranged on the substrate in a dot matrix mode, and the light transmittance and the polarization rate of the shading units are adjustable. The controller is used for receiving a scene image shot by the first camera and a human eye image shot by the second camera, identifying a strong light area position in the scene image, and calculating coordinate values of the strong light penetrating through the shading units on the anti-dazzle film when the strong light enters the human eye according to the human eye position, and adjusting the light transmittance and the polarization rate of the shading units at the corresponding positions according to the coordinate values. According to the system, the light transmittance and the polarization rate of the area needing anti-glare can be changed in a targeted mode, and the light transmittance and the polarization rate of other areas not needing anti-glare are not affected.

Description

technical field [0001] The invention relates to the field of anti-glare technology, in particular to an intelligent anti-glare system. Background technique [0002] In terms of anti-glare, the main use scenarios are car driving, various luminous welding, various occasions where strong light may be seen directly (such as the sun, high-temperature smelting furnace, fishing, gas cutting, etc.); anti-glare for car driving A method similar to that of sunglasses or a method of changing the light transmittance of the entire front glass is mostly used, but the light transmittance of the above method is fixed or the light transmittance of the entire field of view is uniform, which makes the anti-glare not flexible enough. When anti-glare is used, other parts that do not need anti-glare are often temporarily unclear. Therefore, this anti-glare technology is not effective and has certain safety hazards.

[0002]In terms of anti-glare, the main application scenarios include car driving, various luminous welding, various strong light that may be directly seen (such as the sun, high-temperature smelting furnace, fishing , gas cutting, etc.) occasions, etc.; the anti-glare method for driving a car is mostly used in a method similar to that of sunglasses or a method of changing the light transmittance of the entire front windshield, but the light transmittance of the above method is fixed or the light transmittance of the entire field of view Uniformity, which makes the anti-glare not flexible enough. When anti-glare is performed on a certain part, other parts that do not need anti-glare are often temporarily unclear. Therefore, this anti-glare technology is not effective and has certain safety.
