Description

Auxiliary method, device and vehicle for vehicle driving

Technical field

The present invention relates to the field of communications, and more particularly to an assisting method, apparatus, and vehicle for driving a vehicle.

Background technique

Color blindness, also known as congenital visual impairment, refers to the inability to correctly perceive the difference between some or all of the colors. Usually the cause of color blindness is related to heredity, but partial color blindness is related to the eye, optic nerve or brain damage, and may also be due to exposure to specific chemicals.

The red-green blind population accounts for about 8% of the global male population, and the female population is about 0.5%. They can see many colors, but they will confuse certain colors, especially red and green. In addition, about 6% of the world's population is tri-color vision (weak color) ), about 2% of the population is dichromatic vision (color blindness), and very few are monochromatic vision (full color blindness).

Red-green blindness has become Dalton disease, and people with red-green color blindness are difficult to recognize red and green tones. Red-green blindness includes red blindness (protanopia, type A color blindness, first color blindness), green blindness (deuteranopai, type B color blindness, second color blindness), red weak (protanomaly, red sensation often, type A color weak, first color weak) And green is weak (deuteranomaly, type B is weak, second color is weak). Red blindness or green blindness is due to the lack of vertebral cells that respond to greed.

China clearly stipulates that all red and green blind patients are prohibited from obtaining motor vehicle driving licenses. Therefore, red-green color blind patients are not allowed to drive various motor vehicles. The main reason is that red-green color blind patients cannot distinguish widely used red and green traffic lights. There are relatively large traffic hazards in driving vehicles. However, since driving a car is already a daily life need, it is necessary to design a vehicle color blind driving aid. Nowadays, the existing color blind assisted driving device is a driving assistance recognition system based on image recognition, which is notified to the driver through voice form, but the hardware requirements are relatively high, the capital input cost is relatively large, and thus cannot be popularized and applied.

In view of the fact that there is no color-blind driving assistance technology solution with reasonable circuit design, simple and convenient use, low input cost and good use effect in the related art, no effective solution has been proposed yet.
