Abstract

A method and apparatus for acquiring virtual point cloud data are disclosed in an embodiment of that present application. One embodiment of the method comprises: acquiring point cloud data for describing a space object through three-dimensional coordinate points, including a sequence of point cloud data frames formed by a plurality of point cloud data frames; Constructing a virtual three-dimensional space by the point cloud data, wherein the virtual three-dimensional space comprises a virtual object corresponding to the space object; Measuring a virtual object in the virtual three-dimensionalspace at a preset position in the virtual three-dimensional space to obtain virtual point cloud data, wherein the virtual point cloud data is point cloud data relative to the preset position. The embodiment can quickly obtain the annotation information of the virtual point cloud data measured at the preset position of the virtual three-dimensional space and the corresponding virtual point cloud data, thereby improving the efficiency of obtaining the annotation information.

Description

technical field [0001] The present application relates to the technical field of data processing, specifically to the technical field of point cloud data, and in particular to a method and device for acquiring virtual point cloud data. Background technique [0002] Unmanned vehicles need to perceive spatial information, make judgments about the driving environment of unmanned vehicles according to the spatial information, and then issue corresponding control instructions to realize unmanned driving. In order to realize unmanned driving, a large amount of driving state data needs to be collected, and control instructions for various road conditions can be obtained through training on the driving state data. [0003] However, there are still some deficiencies in the existing training process for driving state data. For example, driving state data is usually obtained by collecting actual road condition information from vehicles equipped with on-board data collection equipment....
