The coordinates of the end points of the rotating shaft of the sun visor in the coordinate system are (a, b and c), and the set of all space points of the human eye area in the coordinate system V1 is { (x) 0 ,y 0 ,z 0 )|x 0 ＝x 0 ，y 1 ≤y 0 ≤y 2 ，z 1 ≤z 0 ≤z 2 }。
And 204, obtaining the relation of the coordinate system of the human eye camera to the incident human eye solar rays through the sun position data and all space coordinates of the human eye area of the coordinate system of the human eye camera.
Because the distance between the earth and the sun is far greater than the size of the earth, the sun coordinate does not change along with the change of the position of the coordinate system in any inertial coordinate system on the ground, and the sun coordinate is set as S (x) s ,y s ,z s ) Then, the equation of the ray of the sunlight irradiating any point of the human eye area is:

V 1 The coordinates are subjected to two times of coordinate transformation to obtain V 2 The coordinates are as follows:
x′＝zsinθ-xcosθ，y′＝y-b，z′＝z cosθ+xsinθ (3)
in the above formula, x ', y ', and z ' are respectively coordinate information received by the sun visor controller, and the sun visor controller executes sun shading control according to the coordinate information.
In another embodiment, all spatial coordinates of the human eye region in the human eye camera coordinate system obtained in step 203 do not need to be reset, and all spatial coordinates of the human eye region in the human eye camera coordinate system are already determined when the human eye camera is initially installed, so that all spatial coordinates of the human eye region in the human eye camera coordinate system obtained in the step of obtaining the sunshade region data of the sunshade panel are known data, and step 203 can be omitted.

Fig. 3 is a flowchart illustrating a smart sun-shading method for a sun visor of a vehicle, which is used in a terminal, according to an exemplary embodiment, the method including the steps of:
The detailed processes of step 301 and step 302 are the same as those of the embodiment, and the detailed description is further provided in this embodiment.
And 303, acquiring a coordinate system of the solar incident angle catcher, and acquiring all spatial coordinates of the human eye area of the coordinate system of the solar incident angle catcher through the human eye area space and the coordinate system of the solar incident angle catcher.
Firstly, respectively obtaining a coordinate system of a solar incident angle catcher and a coordinate system of a human eye camera to obtain a relation between the coordinate system of the solar incident angle catcher and the coordinate system of the human eye camera;

the coordinates of the human eye region in V1 space can be found as: { (x " 0 ,y” 0 ,z” 0 )|x” 0 ＝x 0 -d，y 1 -m ≤y” 0 ≤y 2 -m，z 1 -n≤z” 0 ≤z 2 -n}。
And 304, obtaining the relation of the solar ray incident to the human eye in the coordinate system of the solar incident angle catcher according to the solar position data and all space coordinates of the human eye area in the coordinate system of the solar incident angle catcher.
Because the distance between the earth and the sun is far greater than the size of the earth, the sun coordinate does not change along with the change of the position of the coordinate system in any inertial coordinate system on the ground, and the sun coordinate is set as S (x) s ,y s ,z s )，The equation of the ray when the sunlight irradiates any point of the human eye area is as follows:
and 305, obtaining the flat sun shading plate surface relation of the sun incident angle catcher coordinate system through the angle data of the sun shading plate rotation and the sun incident angle catcher coordinate system.
In the solar trap system V1, since the visor plane is always perpendicular to the xOz plane, the equation can be derived as:

and acquiring a sun shield coordinate system, and acquiring sun shield shading area data through coordinates of the sun shield shading area under the sun incident angle catcher coordinate system and the sun shield coordinate system.
