Abstract

The invention relates to a multi-source mobile measurement point cloud data air-ground integrated fusion method, a storage medium and a terminal. The multi-source mobile measurement point cloud data air-ground integrated fusion method comprises the steps: extracting building contour point cloud data A from point cloud data collected by different platforms in a clustering judgment mode, and extracting rod-shaped object point cloud data B from point cloud data collected by different platforms through two-dimensional analysis of three-dimensional gridding; matching the features of the building contour point cloud data A or the rod-shaped object point cloud data B extracted from different platforms, and judging whether the features are the same building contour or the same rod-shaped object ornot; and registering the point cloud data acquired by different platforms through adjustment calculation according to the feature matching result to obtain a registration fusion result. The multi-source mobile measurement point cloud data air-ground integrated fusion method has the advantages that point cloud registration of different platforms is carried out by adopting object-level features, and the applicability is higher, and the precision is higher, and point cloud data acquired by multiple platforms is subjected to fusion management, and integration of multi-time-space and multi-platform data is realized.

Description

technical field [0001] The invention relates to the technical field of inspection and surveying, in particular to a method for air-ground integration of multi-source mobile measurement point cloud data, a storage medium and a terminal. Background technique [0002] LiDAR is a technology for quickly obtaining 3D point cloud data on the surface of objects. It has become a major technical means for 3D earth observation with high spatio-temporal resolution. increasingly important role. In terms of data acquisition platforms, it includes satellite platforms, airborne platforms, vehicle-mounted platforms, ground / knapsack platforms, and so on. [0003] At present, most of the technologies for obtaining 3D point cloud data through lidar use a single platform for point cloud data acquisition. Due to the limited observation range of a single viewing angle and single platform and inconsistent spatial references, in order to obtain all-round spatial information of the target area, not ...
