Night safety meeting system based on machine vision and control method of night safety meeting system

Abstract

The invention provides a night safety meeting system based on machine vision and a control method of the night safety meeting system. The meeting system comprises a photoelectronic imaging system, a digital signal processing and control system and a night vision system. The photoelectronic imaging system is used for collecting digital image signals and transmitting the signals to the digital signal processing and control system, and the digital signal processing and control system controls a high beam and a low beam to be switched according to processed digital information and controls on-off of the night vision system at the same time. The night safety meeting system can reduce high beam interference caused when two vehicles meet no matter whether the opposite side is provided with a lighting control system; meanwhile, the night safety meeting system is simple, reliable, low in misjudgment rate, capable of being combined with an automobile data recorder and strong in practical value and economic value.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety, relates to a vehicle meeting system, in particular to a machine vision-based night safety meeting system and a control method for the system. Background technique [0002] When vehicles meet at night, the high beam lights of one party will cause great interference to the other party, making the driver unable to see the road ahead clearly for a short time, which can easily cause traffic accidents. There are countless similar cases. On the other hand, the high beam lights It is very important for the driver to find objects without active light sources such as pedestrians who are far away when driving at night. [0003] In order to reduce the impact of the high beams on the driver when meeting cars, the far and low beams are generally switched manually. But due to various reasons, the driver often neglects to turn off the high beam, which brings hidden dangers to driving safety. Moreover, m...

AI Technical Summary

Problems solved by technology

However, due to various reasons, drivers often neglect to turn off the high beams, which brings hidden dangers to driving safety.

Moreover, most of the current night meeting systems use photoresistors, which have great limitations. Street lights, neon lights or other roadside auxiliary light sources will have an impact on photoresistors.

Motor vehicle lighting facilities outside the interference range of the vehicle's high beam will also affect the photoresistor sensor, causing the high beam to turn off at the wrong time

At the same time, in practical applications, in order to reduce the interference caused by the high beam lights of incoming vehicles, it mainly depends on whether the incoming vehicles are equipped with similar lighting control systems, which has relatively large limitations.
