Traffic signal indicating lamp is made up of the lamp of the green three kinds of colors of reddish yellow, and the infringement of thumping majority is all at red light
Occur when lighting.Domestic existing traffic signal indicating lamp is the most all upgraded to dot matrix by the coloured glass lampshade in past
LED signal lamp.LED light source all has absolute advantage in terms of brightness, stability and energy-conserving and environment-protective.Owing to brightness is higher, travel
Vehicle in larger distance it is seen that signal lights, beneficially driver adjust in advance travel speed and change traveling lane.
But also just because of the reason that LED signal lamp brightness is higher, cause LED signal lamp very big with the luminance difference of ambient light, night
Between more so, monitoring camera capture infringement time more bother, if exposure parameter is adjusted on the basis of ambient brightness, become
In Xiang, red light overexposure is HUANGBAI(sic) coloured light, and periphery produces bigger halation；If exposure parameter is adjusted on the basis of signal lights
Time, environment blackening in imaging, it is difficult to recognize illegal vehicle, leading to controversy constantly, this technical problem affects friendship always for many years
The quality of logical infringement evidence obtaining.
Summary of the invention
