Description

An automatic video recording and evidence collection and law enforcement system for illegal use of vehicle high beams

technical field

The utility model relates to the field of intelligent traffic management, in particular to an automatic video recording evidence collection and law enforcement system for illegal use of vehicle high beam lights.

Background technique

In safe driving, the proper and reasonable use of high beams not only ensures the safety of drivers, but also does not affect the normal driving of drivers of other vehicles. According to the "Road Traffic Safety Law of the People's Republic of China" and the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China", on roads without central isolation facilities or center lines, vehicles meeting at night should switch to low beams 150 meters away from oncoming vehicles Lights; when a motor vehicle has no street lights at night, poor lighting, or encounters fog, rain, snow, sand, dust, hail and other low-visibility conditions, the vehicle behind and the vehicle in front driving in the same direction are not allowed to use high beams; When driving on street lights or other well-lit roads, high beams should not be turned on. However, there are currently many drivers who do not understand traffic regulations, do not take into account the safety of others, and use high beams incorrectly, which makes driving at night a greater safety hazard.

For the phenomenon of unreasonable use of high beams, there are many deficiencies in current supervision and law enforcement. For drivers, when they find that the high beams are illegally used for oncoming vehicles or vehicles behind, which affects their own safe driving, they can alternately use the high beams and low beams to remind the oncoming vehicles or vehicles to pay attention, and ask them to turn off the high beams lights, switch to dipped beams. However, this approach has no mandatory binding force on the oncoming and following vehicles, and sometimes it cannot achieve the behavior of regulating the use of high beams by other vehicles. For traffic law enforcement personnel, there is not enough police force to patrol and enforce the law on the road. At present, it is mostly fixed-point surprise law enforcement. Light detectors and DV recordings are used on passing vehicles to find illegal use of high beams and corresponding penalties are given on the spot. The coverage of law enforcement is small, and it is impossible to effectively curb the illegal use of high beams.

On the other hand, with the development of intelligent transportation systems and the advancement of on-board electronic equipment technology, the video monitoring of driving vehicles based on digital image processing can already obtain the road condition videos of the vehicle's front view and rear view when driving. Using digital image processing technology, we can not only monitor the front-view and rear-view road condition video images of vehicles while driving in real time, but also automatically obtain information such as current road conditions and license plate numbers of other vehicles from the video images. With the continuous development of digital image processing technology and the maturity of network transmission, remote control and other technologies, the use of these technologies for automatic supervision and evidence collection of vehicles using high beams in violation of regulations, remote law enforcement, etc., can greatly promote vehicle high beam detection And the automation of law enforcement, saving law enforcement resources, while improving the safety of vehicles.

The vehicle-mounted forensics subsystem obtains real-time video images of the front and rear of the vehicle through the video acquisition subunit, and transmits them to the processing subunit; measures the light intensity of the light source through the vehicle light intensity perception subunit, and measures the distance between the vehicle and the vehicle through the vehicle distance measurement subunit. The distance of the vehicle is transmitted to the processing subunit for analysis and processing; the processing subunit displays the incoming data in the display subunit, and stores the video data in the storage subunit in real time.

The processing sub-unit is equipped with a video image acquisition card, and the video image acquisition program is used to collect the road surface returned by the video acquisition sub-unit. On the one hand, the video image is stored in the storage sub-unit. At the same time, the real-time position of the light of the vehicle in front of or behind the road in the image is extracted, so as to obtain the horizontal orientation of the light source vehicle in real time.

Regarding whether the light source vehicle uses high beams in violation of regulations, the processing sub-unit judges vehicle violations based on the collected light source vehicle azimuth, light source light intensity, and light source vehicle distance. The vehicle violations include two situations; the first situation is the illegal use of high beams for oncoming vehicles: the direction of the light source vehicle has a relatively large angle with the central axis of the vehicle, that is, the two vehicles are not in the same lane, and they are about 150 meters away. Under the vehicle distance of the light source, the light source has been detected in the video image frame and the light intensity of the light source increases with the decrease of the vehicle distance. At the same time, the light intensity of the light source exceeds the determined light intensity threshold at a certain distance, then The judgment of the oncoming vehicle using the high beam in violation of regulations is established; the second case is that the following vehicle in the same direction uses the high beam in violation of the regulations: the angle between the direction of the light source vehicle and the central axis of the own vehicle is small, that is, the two vehicles are on the same lane, and the light source vehicle and the own vehicle are in the same lane. The vehicle distance is tens of meters to several meters. According to the light attenuation formula, the light intensity of the measured light source at different distances exceeds a certain threshold sequence, and the determination of illegal use of high beams by the following vehicle is established.
