Abstract: The present disclosure provides a vehicle positioning method, including: a first controller synchronously controlling each first beacon node to send a detection initial signal; a second controller determining a target beacon node among second beacon nodes and controlling the target beacon node to send a detection feedback signal; the first controller synchronously controlling each first beacon node to send a corresponding detection signal to be responded and recording a first moment of sending the detection signal to be responded; the second controller controlling the target beacon node to send a detection response signal; the first controller recording a second moment of receiving the detection response signal and determining a distance between each first beacon node and the target beacon node according to the first moment and the second moment, so as to determine a position of the target beacon node relative to the first vehicle.

Abstract: An anti-glare apparatus includes a lens assembly having an incident side, the lens assembly including a layer of liquid crystal molecules, a first driving electrode and a second driving electrode respectively on both sides of the layer of the liquid crystal molecules, the first driving electrode or the second driving electrode including a plurality of sub-electrodes; a reflective layer on a side of the lens assembly opposite from the incident side; a camera, configured to acquire a human eye's position and acquire an intensity signal of incident light irradiating the incident side of the lens assembly; and a controller electrically connected to the first driving electrode, the second driving electrode, and the camera; where the controller is configured to adjust driving voltages of the sub-electrode based on the intensity signal of the incident light acquire by the camera to change the optical axis direction of the lens assembly.
