Problems solved by technology

[0006] 2. This technology cannot give an estimate of the distance from the center of the lane line offset by the vehicle itself
[0007] 3. This technology cannot distinguish between active lane change and non-active lane deviation based on the state of the vehicle's turn signal, and cannot give an early warning
[0008] To sum up, the existing driving assistance technology cannot well meet people's needs for vehicle driving assistance and early warning during driving. At present, no description or report of a similar technology to the present invention has been found, and no similar technology has been collected at home and abroad. data of

Embodiment Construction

[0067] The following is a detailed description of the embodiments of the present invention: this embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed implementation methods and specific operation processes. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.

[0068] An embodiment of the present invention provides a non-active lane departure warning method based on monocular vision. The method acquires the image data of the front view in real time, calculates the lane departure, avoids the occurrence of illegal driving behaviors such as crossing the line, and reduces the Accident probability due to vehicle offset.

[0069] The non-active lane departure warning method based on monocular vision provided in this embodiment, such as Figure 7 sh...

Abstract

The invention provides a monocular vision-based non-active lane departure early warning method and system. The method comprises the steps of obtaining an image of a road in a vehicle advancing direction in real time based on monocular vision; on the basis of the obtained image, obtaining the positions and types of left and right lane lines in the driving direction through a lane line extraction algorithm; judging the non-active vehicle deviation condition according to the obtained lane line position, lane line type and vehicle left and right turn signal lamp state; and carrying out auxiliary early warning on non-active lane departure occurring in the vehicle driving process according to the non-active vehicle departure condition. The non-active lane departure behavior of the vehicle in thedriving process is effectively reduced, the non-active lane departure behavior is one of main factors of vehicle illegal driving and driving accidents, the driver can be effectively reminded, the occurrence of vehicle illegal driving behaviors such as line pressing is avoided, and the accident occurrence probability caused by vehicle deviation is reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a monocular vision-based non-active lane departure warning method and system. Background technique [0002] Self-driving travel has become a common mode of transportation for people's daily travel, and driving safety during driving has an important impact on people's normal life, and has been paid more and more attention by people. Based on this, the driving assistance system came into being . [0003] After searching found: [0004] The Chinese invention patent application "Lane Line Detection Method for Assisted Driving" with application number 201910008697.X and date of application on January 4, 2019 discloses a lane line detection method for assisted driving. Task convolutional neural network trains image samples, uses the correlation between vehicles and lane lines to assist lane line recognition, improves the detection safety of complex and changeable aut...
