Abstract

A point cloud feature point extraction method, a point cloud sensing system and a mobile platform are disclosed, the method comprising: acquiring a three-dimensional point cloud of an environment in which the mobile platform is located (S201); projecting the three-dimensional point cloud to a horizontal plane in the height direction to obtain a two-dimensional projection point cloud (S202); performing rasterization processing and feature information statistics on the two-dimensional projection point cloud to generate a point cloud information graph (S203); and determining point cloud feature points based on the point cloud information graph (S204). According to the embodiment of the invention, feature points in the point cloud can be effectively extracted based on the point cloud information graph.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a point cloud feature point extraction method, a point cloud sensing system and a mobile platform. Background technique [0002] Positioning technology can provide location and other information for the mobile platform, which is the prerequisite for the mobile platform to carry out path planning, motion control and independent decision-making. At present, a more mature method is to locate the movable platform based on point cloud sensors. Positioning based on point cloud sensors requires online calculation of the complete point cloud collected by the point cloud sensor, and matching based on all point clouds within the effective range. Since the amount of complete point cloud data collected by the point cloud sensor is usually large, the amount of calculation is large when the complete point cloud is calculated online, resulting in the consumption of a large amo...
