The invention relates to an intelligent vehicle-mounted shading device and method in the field of automobiles, the intelligent vehicle-mounted shading device comprises a controller, a shading plate and an image unit connected with the shading plate into a whole, and the controller is connected with the image unit and the shading plate; the image unit is provided with two image sensors which are oppositely arranged, namely a front image sensor and a rear image sensor, and the front image sensor is used for collecting scene image information in front of the eyes of a driver; the rear image sensor is used for collecting face information of the driver to determine positions of human eyes on the face of the driver; the light shielding plate is a light valve array composed of a plurality of rectangular area units, each rectangular area unit can change the working state of the light valve array under the control of different instructions of the controller, and therefore the light transmittance is changed, and the light shielding device has the advantages that local light shielding is effectively achieved, dazzling of strong light is eliminated, meanwhile, most visible areas are not affected, and the light shielding effect is good. And real-time dynamic work can be realized.

    本发明涉及的汽车领域的智能车载遮光装置及方法,包括控制器、遮光板以及与遮光板连接为一体的图像单元,控制器分别图像单元与和遮光板连接;图像单元具有两个相背设置的图像传感器,分别为前图像传感器和后图像传感器,前图像传感器用于采集驾驶员人眼前方的场景图像信息;后图像传感器用于采集驾驶员脸部信息,以确定驾驶员脸部人眼的位置;遮光板是由多个矩形区域单元构成的光阀阵列,每个矩形区域单元在控制器不同指令控制下可以改变光阀阵列的工作状态,从而改变透光度,本发明的效果是有效实现了局部遮光,在消除强光刺眼的同时,保留大部分可视区域不受影响,并可以实时动态工作。
