Abstract

A method and system for generating a lane departure warning in a vehicle are disclosed. The method includes acquiring a plurality of frames of a digital image of a road on which the vehicle is traveling, the digital image including an image of a lane in which the vehicle is traveling and a marking line of the lane, for each of the acquired frames frame, extract the edge point of the frame, analyze the edge point to evaluate the lane departure state, the evaluation includes executing the lane departure verification procedure, which includes identifying the point representing the position of the lane marking line in the frame, if the lane is detected In the method, the lane departure verification procedure includes comparing the positions of the points with the reference positions of the lane by performing the lane departure on the set of acquired frames A lane calibration procedure comprising filtering edge points of the image frame belonging to an area of ​​the frame comprising a horizontal strip of rows of the frame.

Description

technical field [0001] Embodiments of the present disclosure relate to solutions regarding a method of generating a lane departure warning in a vehicle, the method comprising: acquiring a plurality of frames of a digital image of a road on which the vehicle is driving, the digital image of the road including the an image of the lane in which the vehicle is traveling and the marking lines of the lane; for each of these acquired images, edge points of the frame are extracted; the edge points are analyzed to assess the state of lane departure, which assessment includes performing lane a departure verification procedure that includes identifying points in the frame that represent the locations of the lane markings; if the lane departure verification procedure detects a lane departure condition, generating a lane departure warning. Background technique [0002] In automotive applications, a lane departure warning system (LDW) is one of the systems included in an intelligent drivi...
