Document Type and Number:
WIPO Patent Application WO/2022/126427
Kind Code:
A1
Abstract:
A point cloud processing method, a point cloud processing apparatus, a mobile platform, and a computer storage medium. The point cloud processing method comprises: obtaining point cloud data acquired by a ranging device and point cloud density distribution data of the ranging device (S501), the point cloud density distribution data being related to the scanning mode of the ranging device, the point cloud density distribution data comprising a plurality of significance coefficients, and the plurality of significance coefficients being used for characterizing distribution characteristics of mapping points of the point cloud data on a reference surface; determining a predetermined processing mode of the point cloud data according to the significance coefficients corresponding to the mapping points of the point cloud data on the reference surface (S502), the predetermined processing mode comprising at least one of a first processing mode and a second processing mode, the first processing mode being used for increasing the point cloud density in at least part of the area of the point cloud data, and the second processing mode being used for reducing the point cloud density in at least part of the area of the point cloud data; and processing the point cloud data according to the predetermined processing mode (S503).
