Embodiment Construction

[0028] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0029] The 3D point cloud map is mostly used in the positioning, perception and decision-making process of unmanned vehicles. The unmanned vehicle can locate the current position through the 3D point cloud map and know the lane conditions in advance. The above process is realized based on the 3D point cloud map, so the processing of the 3D point cloud map is very important for unmanned vehicles. Important, especially when the 3D point cloud map is compressed and then transmitted to the unmanned vehicle, the amount of transmitted data becomes smaller and the transmission speed is a...

Abstract

An embodiment of the invention provides a road point cloud data processing system and belongs to the technical field of point cloud data processing. The road point cloud data processing system comprises: an acquisition unit for acquiring road point cloud data and vehicle position data of a vehicle at a same moment corresponding to the road point cloud data; a first calculating unit for acquiring vehicle attitude through an SLAM (simultaneous localization and mapping) algorithm according to the road point cloud data and the vehicle position data; a second calculating unit for calculating three-dimensional point cloud map data according to the vehicle attitude; a third calculating unit for extracting, in the three-dimensional point cloud map data, repeated structural data corresponding eachof multiple preset shape parameters so as to obtain extracted three-dimensional point cloud map data; a processing unit for determining three-dimensional point cloud map data compressed. The road point cloud data processing system helps solve the problem of the prior art that three-dimensional point cloud map data high in quantity are difficult to transit and store; the compressed three-dimensional point cloud map data are transmitted to unmanned ground vehicles at high speed.

Description

technical field [0001] The present invention relates to the technical field of point cloud data processing, in particular to a road point cloud data processing system. Background technique [0002] In unmanned driving technology, high-precision positioning is an extremely important component, but in the current technology, the positioning method with the highest accuracy is still based on a three-dimensional point cloud map positioning method. In the process of implementing the present invention, the inventors of the present application found that the prior art has the following defects: the data volume of the 3D point cloud map is large, which brings great difficulties to the transmission and storage of the map. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a road point cloud data processing system, which solves the problem of large amount of 3D point cloud map data in the prior art and is difficult to transmit, a...
