Abstract

The invention discloses a road element vector generation method and system. The method comprises the following steps: acquiring point cloud data and an original image collected in the same area; projecting the point cloud data to a two-dimensional plane to obtain a target image corresponding to the point cloud data; performing semantic segmentation on the road elements in the original image and the target image to obtain semantic segmentation results; and vectorizing the road elements based on the point cloud data and the semantic segmentation result to obtain a road element vector. The technical problem that the generation error of the road element vector is large in the prior art is solved.

Description

technical field [0001] The invention relates to the field of intelligent navigation, in particular, to a method and system for generating a road element vector. Background technique [0002] In order to digitize various road elements in the real world (such as lane lines, stop lines, zebra crossings, etc.), high-precision maps can be produced by using the data collected by unmanned vehicles and high-precision map collection vehicles. However, due to the limitation of data collection accuracy and collection angle, the generation error of the existing road element vector is large, which does not meet the accuracy requirements of high-precision maps. [0003] For the above problems, no effective solution has been proposed yet. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a method and system for generating a road element vector, so as to at least solve the technical problem in the related art that the generation error of the road element vect...
