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

The invention provides a lane departure warning system and its method. The lane departure warning system according to the present invention includes: a camera for photographing the front of the vehicle; a tunnel recognition module that uses at least one piece of information in the front image captured by the camera to identify whether the current position of the vehicle is a tunnel section; The lane line module, when the current position is the tunnel section, confirms whether more than two lane lines are recognized from the front image, and uses the pre-calculated Lane width, generating a virtual lane line at a position corresponding to the identified one lane line; and a judgment and alarm module, using the one lane line and the virtual lane line, or the identified two or more lane lines , to confirm whether the vehicle has lane departure, and when it is confirmed that lane departure occurs, an alarm is issued.

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...
