[0011] Aiming at the problems of the existing products and patents on the glare caused by the high beam lights on the opposite side of driving at night, the temporary blindness of vision, and the improper handling of the situation causing danger to the driver or the surrounding people, the present invention discloses an intelligent anti-dazzling method for eye-tracking cars and System, the present invention predicts and differentially controls the light entering the driver's eyes from different directions, so that the strong light that appears when the vehicle driving on the opposite side suddenly turns on the high beam headlight does not affect the driver's vision, and the high beam light of the vehicle driving on the opposite side is turned on by The strong light that appears when it is far and near does not affect the driver's vision, and at the same time minimally interferes with the light that enters the driver's eyes from the outside world

Embodiment 1
[0059] The working process of Embodiment 1 of the present invention is as follows:
[0060] 1.101 Collect the image outside the car, turn on the dual camera on the car A-pillar, take the required picture, take the picture, identify the picture, identify the light source information that appears in the car, battery car, tricycle, etc., and get the intensity of the light source;
[0061] 2. 102 recognizes the vehicle type, and the unrecognized light source shall be counted as the vehicle lamp;
[0062] 3.103 Calculate the target distance according to the target information;
[0063] 4.104 Obtain the current light source position, and obtain the current possible strong light source position according to the vehicle type information, distance and position information; the unrecognized light source calculates the possible light positions on the other sides according to the lights on one side of the car;
[0064] 5.105 Predict the position of the light source in the future 1. According to the...
Embodiment 2
[0084] The working process of Embodiment 2 of the present invention is as follows:
[0085] 1.101 Collect the image outside the vehicle, turn on the lidar and camera, shoot the image, get the distance information of the image and each point, identify the image and distance information, identify the light source that appears in the car, battery car, tricycle, etc., and get the intensity of the light source;
[0086] 2.102 Identify the vehicle type, and the unrecognized light source shall be counted as the vehicle lamp;
[0087] 3.103 Calculate the target distance based on the target information;
[0088] 4.104 Obtain the current light source position, and obtain the current possible strong light source position according to the vehicle type information and distance and position information; the unrecognized light source calculates the possible light positions on the other sides according to the lights on one side of the car;
[0089] 5.105 Predict the position of the light source in the ...

Abstract
The invention discloses an intelligent anti-dazzling method and system of a sight tracking automobile. According to the system, a sight focus of a driver and an object emitting strong light within a sight angle range are tracked, vision of the driver is not affected by sudden strong light in an opposite direction through difference control of the strong light entering the eyes of the driver in different directions, and meanwhile human intervention on the strong light is reduced as much as possible; according to the system, an existing strong light source is obtained, and light transmittance ofa corresponding part of a windshield is adjusted so that the existing strong light source does not influence the sight of the driver; and meanwhile, according to the system, an existing detected object is used for predicting a light source which may emit the strong light, the position of the possible light source at the next moment is predicted, preventive adjustment is performed, and the sight of the driver cannot be affected by the sudden strong light possibly appearing on the opposite side.
Description
Technical field [0001] The invention relates to an intelligent anti-glare method and system for gaze tracking automobiles, in particular to a smart automobile windshield that recognizes a device capable of emitting a single point of strong light from the outside through a detection device and performs predictive adjustment according to the characteristics and state of the driver's eyes Glass attachments. Background technique [0002] In a very dark environment (when the brightness is lower than 10-²cd / m²), such as at night without light, the cone cells of the human eye lose their photosensitive function, the visual function is replaced by the rod-shaped cells, and the human eye loses the ability to perceive color , It can only distinguish between white and gray. If there is a short-term strong light at this time, the cone cells will directly play a role. The rod cells will not play a leading role because the internal rhodopsin is rapidly decomposed under the strong light. When t...
