Title:
POINT CLOUD DATA AUGMENTATION METHOD AND APPARATUS, AND COMPUTER DEVICE, SYSTEM AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/124780
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of data processing. Provided are a point cloud data augmentation method and apparatus, and a computer device, a system and a storage medium. The point cloud data augmentation method comprises: acquiring point cloud data of a laser radar and a millimeter wave signal of a millimeter wave radar; acquiring three-dimensional cubic data according to the millimeter wave signal, wherein the three-dimensional cubic data includes information in dimensions of distance, speed and angle; acquiring a heatmap distribution map according to the three-dimensional cubic data; performing target extraction on the heatmap distribution map, and determining a target from the heatmap distribution map; on the basis of the target, determining a corresponding target point cloud set from point cloud data that is spatially synchronized with the heatmap distribution map; and performing data augmentation on the target point cloud set. By means of the present application, the problem of the detection accuracy of a target being affected by the fact that point cloud data of a laser radar is relatively sparse can be solved.
