[0044] like Figure 3 As shown, the photosensitive plate 3 includes: a light-transmitting layer 31, a photosensitive layer 32 and a base layer 33. The photosensitive layer 32 is arranged between the light-transmitting layer 31 and the base layer 33.

[0047] Step 101, obtaining geometric data of the light shielding plate and the photosensitive plate, and establishing geometric center coordinate systems on the light shielding plate and the photosensitive plate respectively according to the geometric data of the light shielding plate and the photosensitive plate;

[0048] According to the geometric data of the sunshade 1 and the photosensitive plate 3, a geometric center coordinate system is established with the geometric center point as the coordinate origin. The X and Y axis directions of the geometric center coordinate system point to the driver and parking space directions respectively, so as to obtain the coordinates of each vertex and edge of the geometric figures in the sunshade 1 and the photosensitive plate 3.

[0049] Step 102, obtaining processed photosensitive data, and determining the coordinates of the vertices of the shadow area of ​​the photosensitive plate according to the processed photosensitive data and the geometric center coordinate system;

It should be introduced that when the sun is incident, two areas will be formed on the structure of the photosensitive plate 3, one area is the direct incident area of ​​the sun, and the other area is the shadow area formed by the sunshade 1. The resistance of the direct sunlight area is reduced, resulting in an increase in the current in each microcircuit loop; and because the shadow area formed by the sunshade 1 does not receive direct sunlight, the resistance value is very large, and there is almost no current in each microcircuit loop. According to the parameters of the pre-selected photoelectric sensing resistor, the current threshold can be set. By comparing the current of each microcircuit with the threshold, it can be known which points of the photoelectric sensing resistor on the photosensitive plate 3 are exposed to sunlight and which points are in the shadow position. According to the geometric center coordinate system, the vertex coordinates of the shadow area of ​​the photosensitive plate can be obtained.
