Embodiment Construction

[0045] See figure 1 , a lane departure warning method, comprising:

[0046] Step 1: Obtain the front-view image of the vehicle in the current scene, and at the same time obtain the current vehicle state parameters. In this embodiment, the obtained vehicle state parameters include vehicle speed, acceleration, steering, yaw angle, and brake pedal information.

[0047] Step 2: Process the obtained front-view image, detect the lane line in the front-view image, calculate the lane pre-departure time when the vehicle is driving with the current vehicle state parameters, and display the obtained front-view image, and Mark the detected lane lines.

[0048] Specifically, de-distortion and de-drying preprocessing are performed on the front-view image of the acquired vehicle in the current scene, and then lane line recognition and lane line fitting processing are performed to obtain the lane line;

[0049] See Figure 4 , the lane pre-departure time is calculated by the following form...

Abstract

The invention provides a method, system and device for lane departure early warning and a storage medium. By means of the method, the system and the device, lane departure early warning can be provided accurately in time, and the reliability and sensitivity are good. The method comprises the steps of 1, acquiring a forward view image of a vehicle in a current scene, and simultaneously acquiring current vehicle state parameters; 2, processing the acquired forward view image to detect a lane line in the forward view image, and calculating lane pre-departure time under the condition that the vehicle runs with current vehicle state parameters; and 3, checking whether the lane pre-departure time is less than an alarm threshold value or not, if yes, sending an alarm to carry out lane departure early warning, and if no, not sending the alarm.

Description

technical field [0001] The invention relates to the technical field of automobile driving assistance, in particular to a lane departure warning method, system, device and storage medium. Background technique [0002] According to research, about 50% of the current car accidents are caused by the vehicle's departure from the normal driving lane, mainly due to the driver's distraction, inattention and fatigue driving. The so-called forward-looking lane departure warning system (LDW: Lane Departure Warning) is a system that provides early warning based on the deviation status of the vehicle in the current lane. . According to research report statistics, in the United States, LDW can reduce the total accident rate by 10%. It can be seen that the LDW function has a great effect on reducing vehicle traffic accidents. Since 2013, EU regulations have required that new commercial vehicles in the EU must have this function, which is the first to promote the development of LDW tech...
