The invention discloses a high-definition map
processing method and device based on mobile
laser radar data, and the method comprises the steps: obtaining sensor data collected by a plurality of sensors of an autonomous vehicle, carrying out the probability
data processing, obtaining a structured 3D
point cloud, carrying out the recognition of the 3D
point cloud, distributing a semantic tag, and creating a
geometric mapping function; the method comprises the following steps: constructing a 3D
point cloud image, converting local Euclidean coordinates by adopting a
geometric mapping function to obtain a semantic segmentation result, classifying and correcting the semantic segmentation result by adopting a
confusion network to obtain object attributes, constructing a semantic graph of the 3D point cloud
image based on the object attributes and the
geometric mapping function, and outputting a high-definition map corresponding to the semantic graph. According to the method, the high-definition map is evaluated and optimized to obtain a path navigation result of the autonomous vehicle, multi-target optimization is applied to
processing the mobile
laser radar point cloud to create the high-definition map, a
confusion matrix is used to merge uncertainty
simulation and probability
semantic mapping, and the reliability and accuracy of map generation are improved.
