Abstract

The embodiment of the present application discloses a method and a device for acquiring virtual point cloud data. A specific implementation of the method includes: obtaining point cloud data, the above point cloud data is used to describe space objects through three-dimensional coordinate points, including a sequence of point cloud data frames composed of a plurality of point cloud data frames; Three-dimensional space, the above-mentioned virtual three-dimensional space includes virtual objects corresponding to the above-mentioned spatial objects; the virtual object in the virtual three-dimensional space is measured at a preset position in the above-mentioned virtual three-dimensional space, and virtual point cloud data is obtained, and the above-mentioned virtual point cloud data is relative to The point cloud data of the preset position above. This embodiment can quickly obtain the virtual point cloud data measured at the preset position in the virtual three-dimensional space and the annotation information corresponding to the virtual point cloud data, which improves 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 obtaining 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....
