Problems solved by technology

Different from the lane lines drawn on the road, the geometry of the road boundary line is more diverse, especially at urban intersections and high-speed gates, there will be some complex guardrails and road edges, which is the road boundary required for automatic extraction of high-precision maps. The vectorized data of lines brings difficulties, and the way of manual drawing will greatly reduce the production efficiency of high-precision maps

Abstract

The invention provides a vectorization data generation method of a road boundary line and electronic equipment. The vectorization data generation method of the road boundary line comprises the following steps: obtaining a segmentation point cloud obtained after perception segmentation of a road; points of which the labels are boundary line elements are extracted from the segmentation point cloud to form point sets, so that one or more boundary line element point sets are obtained, and each boundary line element point set comprises points of which the labels are the same boundary line element; instantiating each boundary line element point set to obtain one or more boundary line element instances; refining and sorting points in each boundary line element instance based on the main direction of the local region to obtain one or more ordered boundary point sets; and performing curve fitting and sampling on each ordered boundary point set to obtain vectorization data of the road boundary line. And the production automation rate and the production efficiency of the high-precision map based on the vectorized data of the road boundary line are improved.

Description

technical field [0001] The invention relates to the technical field of high-precision maps, in particular to a method and electronic device for generating vectorized data of road boundary lines. Background technique [0002] High-precision maps are essential for autonomous driving. In the production of high-precision maps, the road boundary line (mainly including guardrails, road edges, etc.) is an important geometric element, and its accuracy and completeness have important reference significance for modules such as positioning and path planning in automatic driving. Different from the lane lines drawn on the road, the geometry of the road boundary line is more diverse, especially at urban intersections and highway gates, there will be some complex guardrails and road edges, which are the road boundaries required for automatic extraction of high-precision maps. The vectorized data of lines brings difficulties, and the manual drawing method will greatly reduce the productio...
