Abstract

The present application relates to a point cloud map quantification method, device, computer equipment and storage medium. The method includes: obtaining geometric features corresponding to each point cloud data in the point cloud map; screening each point cloud data according to each geometric feature, and obtaining lane line point cloud data in the point cloud map and roadsides in the point cloud map Point cloud data; generate two-dimensional line segments based on lane line point cloud data and roadside point cloud data; obtain the relationship between preset surveying points and two-dimensional line segments, and quantify the point cloud map according to the relationship. The method can improve the efficiency of quantifying the point cloud map according to the distance from the surveying point corresponding to the point cloud map to the obtained two-dimensional line segment.

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 ...
