Abstract

The invention relates to a point cloud map quantification method and device, computer equipment and a storage medium. The method comprises the steps: acquiring geometrical characteristics corresponding to point cloud data in a point cloud map; screening the point cloud data according to the geometrical characteristics to obtain lane line point cloud data in the point cloud map and road edge pointcloud data in the point cloud map; generating a two-dimensional line segment according to the lane line point cloud data and the road edge point cloud data; and obtaining a relationship from a presetsurveying and mapping point to the two-dimensional line segment, and quantifying the point cloud map according to the relationship. By adopting the method, the efficiency of quantizing the point cloudmap according to the distance from the surveying and mapping point corresponding to the point cloud map to the obtained two-dimensional line segment can be improved.

Description

technical field [0001] The present application relates to the technical field of machine vision, in particular to a point cloud map quantification method, device, computer equipment and storage medium. Background technique [0002] With the development of automatic driving technology, high-precision point cloud maps play an important role in automatic driving technology. Therefore, the accuracy evaluation of high-precision point cloud maps is particularly important. [0003] In the traditional technology, the error of the feature object in the high-precision point cloud map relative to the surveying point is obtained mainly through manual inspection, and the accuracy of the high-precision point cloud map to evaluate. [0004] However, traditional evaluation methods for high-precision point cloud maps have the problem of low evaluation efficiency. Contents of the invention [0005] Based on this, it is necessary to address the above technical problems and provide a point ...
