Road intersection road condition early warning system and method based on three-frame difference method

Abstract

The invention discloses a road intersection road condition early warning system and method based on a three-frame difference method. The system comprises a peripheral device and a mobile receiving end, the peripheral device is arranged at an intersection, and comprises: an image collector which is arranged at one side of traffic lights at the intersection and is used for collecting the motion states of vehicles, license plates of the vehicles and pedestrians at the intersection; a data analysis device which is arranged on the supporting column provided with the traffic light so as to analyze the running tracks of vehicles and pedestrians at the intersection; a wireless transmission device which is arranged on the supporting column and is used for transmitting an analysis result of the data analysis device to a mobile receiving end in a wireless signal form; an energy device which is arranged at the upper end of the supporting column and used for storing power and providing power for the other devices. The mobile receiving end comprises a vehicle-mounted receiver and a mobile phone receiving end, so as to select whether to provide an alarm signal for a driver and / or a pedestrian according to different signals. The system is energy-saving and environment-friendly, is high in alarm accuracy, is high in pertinence, and can effectively reduce the occurrence of accidents.

Description

technical field [0001] The invention relates to the technical field of road condition early warning systems, in particular to a road condition early warning system and method at road intersections based on a three-frame difference method. Background technique [0002] In recent years, the country has continuously improved traffic rules, increased urban road infrastructure construction, installed traffic lights, set up traffic isolation devices, and implemented measures such as diverting people and vehicles. The number of traffic accidents in cities has dropped significantly, and the safe travel of people and vehicles has been improved. better protection. However, the base number of vehicles and pedestrians in the city is relatively large, the contradiction between pedestrians and vehicles is increasing day by day, and traffic accidents still occur frequently. According to the data released by the National Bureau of Statistics, traffic accidents between pedestrians and vehic...

Although this patent can also give early warning to drivers and pedestrians at the same time to achieve a double warning effect, but it has a relatively large warning range through the way of lighting on the zebra crossing. During that period of time, all vehicles passing through the intersection will receive warning signals. , which will increase the driver's fatigue and tension, and the pertinence is weak
