Embodiment Construction

[0041] method embodiment

[0042] refer to figure 1 , the present invention provides a vehicle-pedestrian collision prevention method, comprising the following steps:

[0043] According to the first real-time motion data of the pedestrian, the pedestrian prediction model is used to dynamically predict the first predicted position of the pedestrian after the set time interval Δt;

[0044] According to the second real-time motion data of the vehicle, a vehicle prediction model is used to dynamically predict the second predicted position of the vehicle after a set time interval Δt;

[0045] According to the first real-time movement speed of the pedestrian, combined with the first predicted position, the first predicted movement area of ​​the pedestrian after the set time interval Δt is drawn;

[0046] According to the coincidence of the first predicted motion area of ​​the pedestrian and the second predicted position of the vehicle, a possible collision between the vehicle and ...

Abstract

The invention discloses a vehicle and pedestrian collision preventing method and system. After a first predicted position of a pedestrian after a set time interval and a second predicted position of avehicle after the set time interval are predicated, a first predicated motion area of the pedestrian after the set time interval is correspondingly drawn according to a real-time motion speed of thepedestrian; and then a possible collision between the vehicle and the pedestrian can be predicated according to a coincidence situation between the first predicated motion area of the pedestrian and the second predicted position of the vehicle; and collision early warning is performed. According to the vehicle and pedestrian collision preventing method and system, by dynamically predicating specific positions of the pedestrian and the vehicle after a section of time in the future, the positions of the pedestrian and the vehicle can be accurately predicated; the predication accuracy is higher;the possibility of the collision between the vehicle and the pedestrian can be effectively predicated so that the collision between the pedestrian and the vehicle is effectively prevented; and therefore, a purpose of reducing traffic accidents is achieved; and the vehicle and pedestrian collision preventing method and system can be widely applied to automobile intelligent technologies.

Description

technical field [0001] The invention relates to the field of driving assistance, in particular to a vehicle-pedestrian collision prevention method and system. Background technique [0002] Along with the massive increase of automobile quantity, automobile safe driving technology is also more and more important. Among them, vehicle-pedestrian collision prevention technology is the main function in car safety driving. This technology can remind drivers to pay attention to pedestrians and reduce the occurrence of collision accidents. Therefore, the accuracy of this technology plays a vital role in car safety driving. [0003] In the current technology, it is generally by predicting the specific position of pedestrians after a period of time, and then by judging whether there is an intersection between the position and the predetermined driving trajectory of the vehicle, to predict whether a collision will occur, so as to issue an alarm. Due to the uncertainty of the movement o...
