A method for calibrating that visual field of a sunshade

A method for calibrate that field of view of sunshade is disclosed. Firstly, the parameters of two-dimensional dummy are designed, and the data of eye point, dummy eye ellipse, H point and V1 point are outputted, wherein H point represents the intersection of human torso and thigh, and then the sunshade on the main driving position is completely folded up to detect the included angle between the straight line between the lower edge of the sunshade and eye ellipse and the horizontal line; Then the sun visor is flipped perpendicularly to the ground, The included angle between the straight line between the lower edge of the sunshade and the output eye point and the horizontal line and the distance between the horizontal line of the V1 point and the sunshade are respectively detected to judgewhether the sunshade meets the requirement or not, and if not, the installation position or size of the sunshade is adjusted until the setting of the sunshade meets the requirement. The method verifies the field of vision of
