Method for detecting lane change of vehicle based on vehicle-mounted camera

Abstract

The invention discloses a method for detecting lane change of a vehicle based on a vehicle-mounted camera. The method comprises the following steps: firstly, initializing a read-in image, and converting the read-in image to a gray space; secondly, segmenting an sky region and a ground region of the image, and acquiring the image of the ground region; thirdly, carrying out edge detection by utilizing the sobel operator; fourthly, carrying out binaryzation by utilizing an Otsu's method; fifthly, restricting a fitting range, wherein hough transformation is restricted by the minimum fitting points, and extracting a lane line equation; sixthly, determining the type of a lane line; seventhly, classifying lane line treatment results; and eighthly, determining the current lane change situation ofthe vehicle. According to the invention, the current lane change situation of the vehicle is detected by adopting the mode of images, the existing vehicle-mounted camera of a driving school is utilized, has low cost, high practicability, diversity detection data, and has accurate and objective evaluations of lane change level for students, the equipment is simple to install, and has wide applications.

Description

technical field [0001] The invention relates to the fields of image processing and traffic video detection, is a vehicle lane change detection method based on a vehicle camera, and is mainly used in vehicle lane change detection and evaluation during driving school road tests. Background technique [0002] Driving has basically become an essential skill in modern society. The number of people taking driver’s license exams is increasing year by year. The increase in driving school students increases the workload of coaches, thus reducing the time for each student to guide, which is not conducive to the improvement of students’ level. In addition, during the process of the driver's license test, occasionally some students used improper means to bribe the examiner, so that they could get the driver's license without solid learning, leaving hidden dangers for road traffic safety in the future. Therefore, some people propose to use some instruments and equipment to automatically ...

Problems solved by technology

[0003] Changing lanes while driving is a very important part of driving. At present, the evaluation of the lane changing level of driving school students mainly depends on the visual inspection of coaches and instructors. The human factor is relatively large, the standards are not uniform, and it relies on continuous judgment by people. After a long time, the effect will be significantly reduced. ,Error-prone

In addition, a small number of driving schools install gyroscopes on the car to judge the lane change of the vehicle. Low, there is not much benefit to the driving level of the students
