Intersection pedestrian recognition safety control system and method based on short-range communication

Abstract

The invention relates to an intersection pedestrian recognition safety control system and method based on short-range communication. The system comprises an information acquiring unit, an image processing unit, a control unit, a pedestrian detection early-warning unit and a communication unit, wherein the control unit is connected with the information acquiring unit, pedestrian and vehicle images acquired by the information acquiring unit are transmitted to an image recognition unit, and acquired traffic signal information is transmitted to the control unit; the image processing unit is used for acquiring and processing an image of the recognition device and comparing the image with a characteristic image of the device so as to obtain a recognition result, and vehicle speed and pedestrian speed obtained through processing are transmitted to the control unit; the control unit is used for performing logic operation on the information basis of the acquired vehicle speed, the pedestrian speed and the traffic signal lamp time. A vehicle and roadside unit communication control module is used for acquiring the traffic state signal in real time, the state of a signal lamp is judged through the control system, and therefore the pedestrian detection early-warning module can be controlled to give an alarm.

Description

technical field [0001] The present invention relates to the technical field of automobile intelligent transportation and active safety, in particular to a safety control system for pedestrian recognition at intersections based on short-range communication, and more specifically, uses the short-range communication technology of the Internet of Vehicles combined with pedestrian image processing technology to deal with emergency collision accidents during operation evade. Background technique [0002] At present, there are more and more vehicles in the city. Due to various factors such as the angle of view and pedestrians, the driver cannot make timely judgments or make wrong judgments on the sudden appearance of pedestrians at the intersection, which leads to abnormal situations. The reaction time is too little, causing various traffic safety accident hidden dangers.

Problems solved by technology

[0002] At present, there are more and more vehicles in the city. Due to various factors such as the angle of view and pedestrians, the driver cannot make timely judgments or make wrong judgments on the sudden appearance of pedestrians at the intersection, which leads to abnormal situations. The reaction time is too short, resulting in various traffic safety accidents

It not only brings harm to people's lives and property, but also affects the congestion of traffic sections and reduces the efficiency of driving.

[0003] In the prior art, some technical means are adopted to avoid these situations as much as possible, such as setting warning signs at crossroads, and warning vehicles and pedestrians to slow down. This method can play a certain role, but the practicability is not high ; Another example is to arrange personnel to be on duty at the intersection, and to command vehicles and pedestrians. This method can effectively reduce the situation of pedestrians passing through the intersection and vehicles at a faster speed, but it needs to invest a lot of manpower and material resources.
