Embodiment Construction

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the invention.

[0050] The object of the present invention is to provide a method for lane line recognition, the method comprising the following steps:

[0051] In step 1, binarization preprocessing is performed on the acquired video image;

[0052] In step 2, the possible pixel points of the lane line are searched, and the possible pixel points of the lane line are simulated at the same time;

[0053] In step 3, a lane line search area is generated, lane points are found in the search zone, and lane lines are drawn by fitting.

[0054] In the embodiment of the present invention, the pixel size of the video obtai...

Abstract

The invention belongs to the technical field of image processing, and provides a method for recognizing a lane line. The method includes the steps of conducting binarization preprocessing on an obtained video image, then researching possible pixels of the lane line and simulating the possible pixels which produce the lane line at the same time, finally, producing a lane line search area, looking for lane points in a search band, and fitting and drawing the lane line. According to the method for recognizing the lane line, a counting process is simple, the recognition accuracy rate is high, actual using needs are effectively met, the lane line can be dynamically tracked so that the running status of a vehicle can be recognized, a reliable guarantee is provided for safe and reliable driving of a driver, practicability is strong, strong popularization value and application value are achieved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for lane line recognition. Background technique [0002] In the 1980s, the first automobile began to be produced and developed for more than 100 years. In the past 100 years, the machinery manufacturing industry has developed rapidly. Until today, the automobile has become an indispensable means of transportation for human beings. one. The utilization rate of automobiles is constantly expanding, and the safety of automobile driving has become increasingly prominent and important. Relevant data from the transportation departments of the United States and China show that the accidents caused by vehicles deviating from the lane during automobile driving are traffic accidents. an important part. Another report also pointed out that nearly 51% of traffic accidents have a lot to do with cars leaving their lanes unintentionally. The researchers found tha...
