Title:
ANTI-DAZZLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/109745
Kind Code:
A1
Abstract:
An anti-dazzle device, which relates to the technical field of optics. The anti-dazzle device comprises a strong light detection device, a human eye position detection device, a data processing device, a driving device, and a light blocking device. The strong light detection device is used for detecting strong light and a direction thereof, and the strong light is the light whose light intensity is greater than a first light intensity threshold. The human eye position detection device is used for detecting the position of a human eye. The data processing device is in communication connection with the strong light detection device, the human eye position detection device and the driving device, and is used for calculating a target position of the light blocking device according to information detected by the strong light detection device and the human eye position detection device, and sending the target position to the driving device. The driving device is connected to the light blocking device so as to move the light blocking device to the target position. The light blocking device is used for weakening or blocking the direct incidence of the strong light to the human eye at the target position. The anti-dazzle device can effectively prevent dazzle while not reduce the observation ability of human eyes to the surrounding strong-light environment.
