Abstract: A new generation of network resource management architecture for coverage is provided, which constructs a structure of “signal coverage+capacity coverage” by incorporating satellite, space-based, and ground access points to achieve large-scale regional signal coverage and local area capacity coverage. In the core network, a global resource orchestrator is added, and in the access network, local resource orchestrator and virtual network management and maintenance unit are added for multiple functional units of resource management and control. In terms of coverage structure, it is divided into three-dimensional dense capacity coverage and three-dimensional global signal coverage. The former consists of ground dense network and aerial ad-hoc network, respectively realizing high traffic density coverage and large connection three-dimensional coverage.

Abstract: An airborne LiDAR point cloud filtering method based on super-voxel ground saliency is provided. The method begins by denoising the input LiDAR point cloud, employing a boundary-preserving TBBP super-voxel algorithm for super-voxel segmentation. The super-voxels are categorized into scanning bands in N directions based on their centroid coordinates. Subsequently, each direction's scanning bands are sorted, segmented, and their saliency values are computed. Utilizing saliency values as coordinating factors, an energy function for the optimal filtering plane is constructed and minimized, leading to the determination of the optimal segmentation plane. Ground and non-ground points are classified based on the segmentation plane, thereby establishing the point cloud filtering results. The use of super-voxel-based saliency calculation in this invention enables preliminary vertical filtering of target point clouds, addressing the challenge of misclassifying point clouds with concave structures as ground points.
