Abstract

The invention discloses a lane departure pre-warning method, instrument and system. The lane departure pre-warning method consists of the following steps: obtaining a facial image of a driver collected by a rearview collection unit of a vehicle, a lane departure image collected by a forward-looking collection unit and a turn signal lamp state collected by a turn signal lamp signal collection unit; when it is detected that the vehicle is off track and a turn signal lamp of the vehicle is not on, giving a warning of lane change based on the facial image and the direction in which the vehicle deviates from the lane. The lane departure pre-warning method has the advantages of increasing the accuracy of vehicle lane change pre-warning and reducing the probability of traffic accidents.

Description

technical field [0001] The invention relates to the technical field of vehicle driving safety, in particular to a method, device and system for lane departure warning. Background technique [0002] The lane departure warning system is a system that assists the driver to reduce traffic accidents caused by lane departure by means of an alarm. The current lane departure warning system consists of an image processing chip, a controller, and sensors. When the lane departure system is turned on, the camera installed on the side or front of the vehicle will always collect images of the driving lane, and perform image processing on the collected images to obtain the position parameters of the vehicle in the current lane. When the vehicle is detected to deviate from the lane , the sensor senses data such as the vehicle's driving speed and the status of the turn signal. When the vehicle speed is high and the turn signal is not turned on, the controller sends an alarm signal. The whol...
