Abstract

The embodiment of the invention relates to a semantic map generation method, device and system, a storage medium and electronic equipment. The method relates to the technical field of vehicle navigation, and comprises the steps of carrying out image correction on a plurality of left and right images included in an original image to obtain a plurality of stereo image pairs, and carrying out semantic segmentation on each stereo image pair to obtain a semantic category corresponding to each stereo image pair; performing stereo matching on each stereo image pair and the semantic category corresponding to each stereo image pair to obtain a disparity map of each stereo image pair, and generating single-frame semantic dense point clouds of each left image and each right image according to the disparity map of each stereo image pair; and generating a global semantic dense point cloud of the original image according to each single-frame semantic dense point cloud, and generating the semantic map according to the global semantic dense point cloud. According to the embodiment of the invention, the semantic map generation efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle navigation, and in particular, relate to a method for generating a semantic map, a device for generating a semantic map, a system for generating a semantic map, a computer-readable storage medium, and electronic equipment. Background technique [0002] High-precision maps, as an important part of automatic driving or unmanned driving systems, play a vital role in the perception of the vehicle's surrounding environment, high-precision positioning, and lane-level path planning and decision-making. [0003] At present, the main technical process of high-precision map production includes five basic links: data collection, data preprocessing, automatic identification, manual verification and correction, compilation and release. Specifically, at the current stage, the production of high-precision maps mostly needs to combine the 3D laser point cloud data obtained by laser radar and...
