Abstract

The invention discloses a method for identifying and tracking target barriers in surrounding environment. The method comprises the following steps: acquiring video road condition information surrounding a vehicle by utilization of a camera of the vehicle; defining the range of a dangerous region according to the position of the vehicle, the speed of the vehicle, lane changing information and a lane width; filtering out the target barriers in the dangerous region by utilization of the video road condition information, and detecting the relative position, the relative speed and the danger coefficient between each target barrier and the vehicle; tracking the movement track of the target barrier of which the danger coefficient exceeds the preset threshold so as to predict the relative movement of the target barrier relative to the vehicle; and determining a possible or upcoming collision accident according to the predicted relative movement of the target barrier relative to the vehicle.

Description

technical field [0001] The invention relates to a method and equipment for identifying and tracking obstacle targets in the surrounding environment of a vehicle, which can monitor multiple targets around the vehicle by using a vehicle-mounted camera to provide driving assistance. Background technique [0002] With the advent of the automobile era, the number of motor vehicles has increased greatly, road congestion and overload, frequent vehicle jams, and frequent traffic accidents have caused a large number of casualties and heavy property, which has become a serious social problem all over the world. more and more attention. Among them, the obstacle recognition and tracking algorithm based on vehicle sensors plays a vital role in the field of vehicle safety. The essence of the on-board camera recognition system is to recognize a variety of targets in video road conditions, including fast-moving targets (such as moving vehicles, including vehicles in adjacent lanes), slow-m...
