Abstract
The invention discloses a traffic intersection accident prevention system implementation method adopting combination of a V2I and a camera. The traffic intersection accident prevention system implementation method comprises the steps that: a central controller is arranged at the center of a traffic intersection, wherein the central controller can receive information of all vehicles and information of pedestrians in the intersection within a range of 100 meters of the traffic intersection in real time; each vehicle is equipped with an information acquisition node, which acquires information including model, license plate number, speed and the like of the vehicle and can transmit the data to the central controller of the traffic intersection in real time; and the central controller receives and processes the information of the vehicles and the pedestrians, and feeds back dangerous condition to the vehicles. Through rapid and intelligent recognition and judgment, the traffic intersection accident prevention system implementation method can be used for monitoring real-time condition of the vehicles and the pedestrians, such as license plate numbers, models, driving speed, positions and directions of the vehicles as well as trajectories of the pedestrians, can be used for forecasting the moving trajectories of the vehicles and the pedestrians in a period in future, and can be used for calculating to determine whether collision will occur, so as to avoid the occurrence of accidents.
Description
Technical field
The present invention relates to computer built-in field, the traffic intersection traffic accident prevention system that specifically a kind of V2I of employing is combined with photographic head realizes method.
Background technology
Bus or train route cooperative system (VehicleInfrastructureIntegration, V2I) technology such as radio communication, sensor measuring that is based on carries out bus or train route acquisition of information, mutual by car car, bus or train route information and share and realize vehicle and the systems technology of the intelligent coordinated cooperation of infrastructure.
And apply the process that the video that photographic head shoots by moving object detection track algorithm, Track Pick-up and length computation algorithm carries out and can calculate the path of pedestrian.
Presently, but without effective traffic intersection traffic accident prevention system, V2V, V2I technology is in the research experiment stage, a lot of automobile production companies are all in research correlation technique at present, but real for implementing also for some time, and be also conceptual proposition for the how real transport solution crossing traffic accident of this technology, not for this technology detailed system method to this application.
Summary of the invention
The technical assignment of the present invention is to provide a kind of V2I of employing traffic intersection traffic accident prevention system being combined with photographic head and realizes method.
The technical assignment of the present invention realizes in the following manner, and the method is as follows:
1) one central controller, the information of all automobiles within the scope of energy real-time reception distance traffic intersection 50-150m and the information of crossing pedestrian are set in traffic intersection central authorities；Each automobile is equipped with an information collection node, and the data of information collection node collection can send to the central controller of traffic intersection in real time；Controller processes after receiving the information of vehicle and pedestrian, and unsafe condition is fed back to automobile；
2) central controller at crossing utilizes the video that photographic head is shot by certain algorithm to process, and calculates running orbit and the predicted path of pedestrian, thus carrying out monitor in real time；
3) central controller at crossing is divided into general modfel and special pattern, is in general modfel during normal condition；Whether be in special pattern when emergency situations being detected, after entering special pattern, automobile will be carried out path prediction by controller, by colliding in certain algorithm detection following certain period, then feed back to the automobile that will collide rapidly.
The information of described information collection node collection includes the model of automobile, car plate, speed, vehicle color.
Described certain algorithm is moving object detection track algorithm, Track Pick-up and length computation algorithm.
Compared to the prior art the V2I traffic intersection traffic accident prevention system being combined with photographic head that adopts of the present invention realizes method, judged by quick, intelligent identification, the real-time status of automobile and pedestrian can be monitored, the car plate of such as automobile, model, travel speed, position, direction, the driving trace of pedestrian；And the running orbit of automobile and pedestrian's a period of time in the future can be predicted, calculate and whether can collide thus avoiding the generation of traffic accident.
Accompanying drawing explanation
Accompanying drawing 1 is the configuration diagram adopting the V2I traffic intersection traffic accident prevention system being combined with photographic head to realize method.
