16 Claims

1. A light shielding plate assembly, comprising: a transparent panel, an image collecting module, a detection module and a control module; wherein,

the transparent panel is configured to block a light passing through the transparent panel and arriving at a human eye, and a light transmittance of the transparent panel is adjustable, wherein the transparent panel is divided into a plurality of control areas, and each control area comprises a corresponding coordinate information range;

the image collecting module is located on a side of the transparent panel away from the human eye, and is configured to obtain image information of the transparent panel and the human eye;

the control module is configured to: determine target position information of a gaze point of the human eye positioned on the transparent panel according to the image information, and determine a target control area corresponding to the target position information among the plurality of control areas as the target control area, wherein the target location information comprises coordinate information, and the target position information is located in a coordinate information range corresponding to the target control area;

the detection module is configured to: detect optical information when the light passes through the target control area and arrives at the human eye;

the control module is further configured to: adjust the light transmittance of the transparent panel in the target control area according to the optical information, so that the optical information is within a preset range.

9. A control method of a light shielding plate assembly, the light shielding plate assembly comprising a transparent panel, an image collecting module, a detection module, and a control module, wherein, the transparent panel is configured to block a light passing through the transparent panel and arriving at a human eye, and a light transmittance of the transparent panel is adjustable, wherein the transparent panel is divided into a plurality of control areas, and each control area comprises a corresponding coordinate information range; the image collecting module is located on a side of the transparent panel away from the human eye; the control method includes:

obtaining, by the image collecting module, image information of the transparent panel and the human eye;

determining, by the control module, target position information of a gaze point of the human eye positioned on the transparent panel according to the image information, and determining a target control area corresponding to the target position information among the plurality of control areas as the target control area, wherein the target location information comprises coordinate information, and the target position information is located in a coordinate information range corresponding to the target control area;

detecting, by the detection module, optical information when the light passes through the target control area and arrives at the human eye;

adjusting, by the control module, the light transmittance of the transparent panel in the target control area according to the optical information, so that the optical information is within a preset range.

16. A control device of a light shielding plate assembly, applied to a vehicle, wherein the light shielding plate assembly comprises a transparent panel, the transparent panel is divided into a plurality of control areas, and each control area comprises a corresponding coordinate information range, and the control device comprising: a memory and a processor, the processor being configured to execute the following instructions stored in the memory:
