Problems solved by technology

However, since there is usually only a slight height change at the road boundary, there is no effective marking similar to the lane line, and the existence of roadside shrubs, etc., the extraction of the road boundary line is very difficult, and the vehicle may not be able to recognize the road boundary line during automatic driving. thus increasing the safety hazard

Abstract

The invention provides a method, device, equipment and storage medium for determining road boundary lines. The method includes: extracting feature points satisfying linear feature conditions from the point cloud data of the road; filtering and optimizing the initial road boundary formed by the feature points, and extracting optimized boundary points; fitting the boundary points , to get the fitted road boundary line. The continuity and smoothness of the road boundary line extracted by the embodiment of the present invention are better.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a method, device, device and storage medium for determining a road boundary. Background technique [0002] With the advancement of science and technology, especially the development of automobile manufacturing and information technology, autonomous driving technology has become a research hotspot in recent years, and the safety of vehicles in autonomous driving is very important. [0003] The road boundary line gives strong constraints on the boundaries on both sides of the road, which is crucial for the safe driving of vehicles in autonomous driving. However, since there is usually only a slight height change at the road boundary, there is no effective marking similar to the lane line, and the existence of roadside shrubs, etc., the extraction of the road boundary line is very difficult, and the vehicle may not be able to recognize the road boundary line during...
