S03, measure and record actual visibility data of each section in tunnel under the conditions of different visibility environments；
S04, measure and record each section in tunnel under the conditions of different visibility environments, the reality in each section in tunnel can be made
When border brightness meets the brightness requirement that step S02 calculating is obtained, the brightness regulation data of each section illuminator；
The actual visibility number of S05, each section in tunnel extracted with step S03 under the conditions of different visibility environments
According to, and step S04 extract each section illuminator brightness regulation data based on be fitted, set up each section in tunnel
Under the conditions of different visibility environments, visibility and lamp lighting brightness transition model；
S06, visibility and lamp lighting brightness transition model according to step S05 acquisitions, correct the lamp in each section in tunnel
Has brightness of illumination.
Compared with prior art, beneficial effects of the present invention：
(1) present invention in the case where not increasing additional hardware equipment, by directly adjust the brightness of light fixture in tunnel come
Improve the state of visibility in tunnel, to increase visual brightness and target object and the background contrasts in tunnel, and then improve
The driving safety coefficient of driver in tunnel；
(2) present invention is according to visibility difference in tunnel, and control lamp brightness change, substitution maximizes the skill of lamp brightness
Art scheme, both can guarantee that the demand of brightness in tunnel, also achieve the saving of resource.
