Problems solved by technology

[0005] However, the existing generation of virtual lane lines increases the load of the system, and the calculation reliability is low, and errors in generating virtual lane lines continue to occur
Therefore, the existing lane departure warning system often sends out false lane departure warnings, which reduces the convenience of the driver and the reliability of the product.

Abstract

A lane departure warning system and method are provided. The lane departure warning system includes a camera, a tunnel recognition module, a virtual lane module, and a determination/warning module. The camera captures a front image of a vehicle. The tunnel recognition module determines whether a current position of the vehicle is in a tunnel section, using the front image captured by the camera. The virtual lane module determines whether two or more lanes are detected from the front image when the current position is in the tunnel section and, when only one lane is detected, generates a virtual lane at a position corresponding to the one lane using a pre-calculated road width. The determination/warning module determines whether the vehicle departs from a lane, using the one lane and the virtual lane or the two or more lanes detected, and warns of lane departures accordingly.

Description

technical field [0001] The present invention relates to a lane departure warning system, in particular to a lane departure warning system and a method for generating a virtual lane line and confirming whether a vehicle has lane departure when a lane is misidentified. Background technique [0002] At present, there is an increasing trend of advanced vehicles, such as advanced safety vehicles (Advanced Safety Vehicle), which apply high-end electronic technology and control technology. [0003] As a part of the advanced safety vehicle, the lane departure warning system senses the front image of the vehicle through the camera installed on the vehicle, recognizes the lane line that the vehicle is currently driving, and sends an alarm to the driver in the event of lane departure. [0004] Existing lane departure warning systems generate virtual lane lines based only on lane width information on roads where lane lines cannot be recognized due to guardrail shadows or backlighting, e...
