Embodiment Construction

[0055] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar parameters or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0056] The object of the present invention is to propose a lane departure warning method and system for preventing repeated warnings of unilateral deviation, which defines warning lines, internal recount lines, external recount lines, and warning end lines. Combined with the positional relationship and transformation relationship between the actual position of the vehicle and the lines involved in the judgment, a set of lane departure alarm logic that can effectively prevent repeated alarms for unilateral departures is designed.

Abstract

The invention discloses a lane departure warning method and system for preventing repeated warning of one-side lane departure. The method comprises the following steps of acquiring a road image in front of a vehicle; identifying a lane line of a lane in which the vehicle is located from the road image; and because a warning line, a warning end line and an external recount line are arranged at a one-side lane line, when the outer side surface of a tire on one side of the vehicle is beyond the warning line but a driver is unconscious, performing lane departure warning. The lane departure warning method and system for preventing repeated warning of one-side lane departure disclosed by the invention can judge whether the tire on one side of the vehicle is beyond the external recount line, and if not, another lane departure warning is prohibited to execute, so that the problem that the left wheel and the right wheel respectively trigger the lane departure warning is effectively solved; and if yes, a situation whether the tire on one side of the vehicle is beyond the warning end line is judged, and if yes, another lane departure warning is allowed to execute, so that the situation that the warning is missed out cannot occur.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a lane departure warning method and system for preventing repeated warnings of unilateral deviation. Background technique [0002] The lane departure warning system has been widely used at present, and the system carries out road video collection through a camera installed in front of the vehicle. The Lane Departure Warning System provides intelligent lane departure warning, which sends an alarm after the vehicle deviates from the lane, providing the driver with more time to react. The lane departure warning system can recognize when the vehicle deviates from the lane, and when it detects that the vehicle has deviated from the lane unintentionally, for example, when the driver is in poor spirits, careless, fatigue driving, changes in road conditions, and vision has not been restored when entering and exiting a tunnel, When changing lanes without turning on the turn s...
