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.

    本发明涉及防眩光技术领域,公开了一种智能防眩光系统,该系统包括控制器、用于实时拍摄车辆前方的场景图像的第一摄像头、用于拍摄驾驶员的人眼图像的第二摄像头和防眩膜;防眩膜包括基板和设于所述基板上的多个点阵排布的电控的遮光单元,所述遮光单元的透光率及偏振率均可调;控制器用于接收所述第一摄像头拍摄的场景图像及所述第二摄像头拍摄的人眼图像,识别所述场景图像中的强光区域位置,并根据人眼位置计算强光射入人眼时穿过所述防眩膜上的遮光单元的坐标值,根据所述坐标值调节对应位置的所述遮光单元的透光率及偏振率。本发明能够针对性地改变需要防眩光区域的透光率及偏振率,而不影响其他不需要防眩光的区域的透光率及偏振率。
