The invention belongs to the technical field of vehicle-mounted intelligence, and relates to a vehicle-mounted intelligent sun shield system based on eyeball capture and a sun shading method. The system comprises a sun shield, an eyeball tracking sensing unit, a control unit, a light intensity sensing unit and a refractive index adjusting unit; the light intensity sensing unit acquires light source information and transmits the light source information to the control unit; the eyeball tracking sensing unit identifies the scaling of the current eyeball pupil of the user, analyzes the eye light receiving coefficient of the user, analyzes whether the current environment light source is appropriate or not, and transmits analysis information to the control unit in real time; the control unit analyzes and compares the light source information transmitted by the light intensity sensing unit with the information transmitted by the eyeball tracking sensing unit, and transmits control information to the refractive index adjusting unit; the refractive index adjusting unit changes the transmission coefficient of the sun shield in real time according to the control information; according to the sun shield system, the refractive index of the sun shield is automatically adjusted; the sight range of the driver is reserved; the device is highly integrated, light in weight and thin in thickness.
