Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The purpose of the paired lane line detection method described in the embodiment of the present invention is to overcome the paired lane line detection method in the prior art. The detection calculation process takes a certain amount of time. If the car is driving at high speed, it will cause the detection results to lag and the real-time detection of defects is low. However, if a simple lane line judgment method is adopted, errors in the detection results are prone to occur, which affects the user's judgment. Below in conjunction with accompanying drawing, the present invention will be fur...

Abstract

A detection method for paired lane lines, the method comprising: obtaining two straight lines to be detected, respectively selecting sample points on the two straight lines according to a preset distance, and obtaining the difference between the sample points and the predetermined The distance vector between the common points; the distance vector is substituted into the preset artificial neural network to calculate the excitation value, wherein the weight vector of the artificial neural network is obtained according to the training of the paired lane line sample data collected in advance; according to The excitation value output by the artificial neural network is used to judge whether the two straight lines are paired lane lines. The method can effectively ensure the real-time performance of judging the paired lane lines, and can also improve the accuracy of judging.

Description

technical field [0001] The invention belongs to the field of automatic driving, and in particular relates to a detection method and device for paired lane lines. Background technique [0002] The lane departure warning system is an auxiliary system that assists the driver to reduce traffic accidents caused by lane departure by means of an alarm. When the vehicle deviates from the driving lane, the lane departure warning system can issue an early warning reminder, and the early warning reminder can include alarm sound, steering wheel vibration or automatic steering change, etc. [0003] In the lane departure warning system, in order to ensure the accuracy of the warning, it is necessary to correctly extract and identify the lane lines. The current paired lane line detection method generally needs to consume more system resources. When higher accuracy is required, it needs to spend a certain amount of computing time, which cannot guarantee real-time detection; or, in order to...
