Problems solved by technology

[0003] In bad road conditions, lane markings usually appear discontinuous and unclear. It is difficult for existing vehicle detection algorithms to detect continuous straight or curved lane lines, and usually only intermittent lane lines or discrete lane lines can be obtained. edge point
In this case, it is impossible to accurately obtain the angle between the car body and the lane line with high precision and the lateral offset of the car body in the lane, and it is difficult to achieve accurate positioning of the lane line

Abstract

The invention provides a lane line positioning method and device, electronic equipment and a readable medium. The method comprises the steps of obtaining multiple pieces of two-dimensional point information of a lane line through an image; determining a plurality of coordinate conversion equations according to the three-dimensional projection relationship and camera parameters; performing parameter estimation on the coordinate transformation equation based on the plurality of pieces of two-dimensional point information to obtain a two-dimensional offset parameter of the vehicle; and positioning the lane line according to the two-dimensional offset parameter. According to the lane line positioning method and device, the electronic equipment and the readable medium, when lane line detectionis inaccurate, the high-precision included angle of the vehicle body relative to the lane line and transverse deviation of the vehicle body in the lane can still be obtained, so that the lane line isaccurately positioned.

Description

technical field [0001] The present application relates to the field of intelligent driving, and in particular to a lane line positioning method, device, electronic equipment and computer readable medium. Background technique [0002] During the driving process of the vehicle, the lane line detection and positioning method can be adopted to identify the lane line to realize intelligent driving. At present, there are many methods based on visual lane line detection, and they are relatively mature. However, in order to obtain a high-precision angle between the vehicle body and the lane line and the lateral offset of the vehicle body in the lane, the lane line positioning algorithm has relatively high requirements for the lane detection algorithm, which requires the ability to detect continuous straight or curved lane lines. [0003] In bad road conditions, lane markings usually appear discontinuous and unclear. It is difficult for existing vehicle detection algorithms to detec...
