Problems solved by technology

However, the anti-glare means of this system is to change the high beam lighting system in real time. For the driver, the active performance is not strong, and the change of the lighting system means the loss of road lighting. Considering the particularity of the shading system , unable to effectively observe the driving vehicles on the road, which may cause new hidden dangers to driving

Embodiment

[0050] When the driver turns on the anti-glare driving assistance system of the present invention when driving at night, the data processing and control unit 3 initializes and loads preset parameters. Initialization includes the start-up process of the operating system carried by the data processing and control unit, as well as the preparation of the program before the system starts to work normally, the necessary steps to make the light source sensing unit 2 and the liquid crystal glass unit 1 enter the working state, etc. The preset parameters include: the relative position information of the driver's eyes and the liquid crystal glass unit 1, the determination conditions of strong light, the intensity range and chromaticity range, and the driver's field of view covered by the liquid crystal glass in the image collected by the light source perception unit 2 The area (effective area) pixel coordinates.

[0051] The light source sensing unit 2 starts to collect the driver's dri...

Abstract

The invention discloses an anti-dazzling driving auxiliary system based on liquid crystal glass. The anti-dazzling driving auxiliary system comprises a liquid crystal glass unit, a light source sensing unit and a data processing and controlling unit. The liquid crystal glass unit comprises dot-matrix liquid crystal glass and a driving component, and the driving component is used for changing the light transmittance of all dot matrixes of the dot-matrix liquid crystal glass according to the dot-matrix state information of the data processing and controlling unit. The invention further discloses an anti-dazzling method of the anti-dazzling driving auxiliary system based on the liquid crystal glass. Regional shading is carried out through the dot-matrix liquid crystal glass, the reaction to hard light of the eyes of a driver can be relieved, the effect of hard light irradiation on driver driving is relieved, and meanwhile the illumination to other parts of a road is relatively not affected.

Description

technical field [0001] The invention belongs to the technical field of anti-dazzling vehicles, in particular to an anti-dazzling driving assistance system based on liquid crystal glass and an anti-dazzling method thereof. Background technique [0002] During the driving process of the vehicle, the driver's eyes are often stimulated by strong sunlight and the headlights of the oncoming vehicle, causing the driver to feel dazzled, affecting the driver's sight, and easily causing traffic accidents. In response to this type of situation, some drivers currently adopt the method of attaching a solar film on the front window glass or wearing sunglasses while driving to reduce the irritation to the eyes. However, such methods attenuate the incident light intensity as a whole, as does the ambient incident light intensity. Due to the strong adaptability of the human eye, the pupil will enlarge accordingly, and the stimulation of the glare of the headlights will also rebound according...
