Abstract

The invention relates to an intelligent anti-glare method and the structural improvement of the device. It includes a photosensitive device, a data processing device connected with the photosensitive device, the data processing device is connected with the filter device, and the filter device is connected with the display device; the data processing device includes a video processing chip. The intelligent anti-glare method includes the following steps: signal collection: using a photosensitive device to collect external light; data processing: processing the data collected by the photosensitive device by a data processing chip to determine the position of a strong light source; light filtering processing: according to The position of the strong light source judged by the preset light intensity threshold in the data processing device, according to the control signal, the filtering device realizes the filtering operation; display: according to the processing result of the filtering device, the signal is collected by the anti-glare camera, and displayed in the output on the display. It overcomes the glare defect of driving at night, effectively avoids accidents, and improves safety performance; it has strong data processing capabilities, high integration, and is easy to assemble and debug.

Description

technical field [0001] The invention relates to the field of safe driving, in particular to an intelligent anti-glare method and structural improvement of the device. Background technique [0002] Glare is divided into direct glare and reflected glare. The glare phenomenon seen by drivers at night is due to the fact that the ratio of the reflected light intensity of the headlights of the car to the road surface and the direct light intensity of the other headlights is too small, so that stronger light is incident on the road surface. In the human eye, the photoreceptor cells corresponding to the light source on the retina of the eye make the pupil of the eye narrow and suppress the signal imaged by the corresponding dark background of the surrounding photoreceptor cells, so that the human eye cannot see clearly or cannot see the dark surroundings of strong light background. [0003] When driving at night, especially when meeting cars, the glare produced by the headlights of...
