The invention belongs to the field of unmanned aerial vehicle (UAS)
traffic management (UTM) and
computer science, and particularly relates to a method and
system for airspace modeling and path planning of a logistics unmanned aerial vehicle, and the method comprises the steps: S1, receiving multi-
source data, and constructing a hierarchical mixed
data model; s2, coding the control constraint data and the dynamic environment data into semantic attributes of nodes in a two-dimensional
quadtree layer and / or voxels in a three-dimensional
octree layer so as to generate a semantic airspace model containing computable rules; s3, based on the semantic airspace model, executing a hierarchical path planning
algorithm to determine a flight path from the starting point to the ending point; and S4, combining the refined paths, and outputting a four-dimensional flight path containing a
timestamp. The airspace rule is internalized into the model attribute, the real-time performance, safety and compliance of path planning are remarkably improved, the airspace
resource utilization efficiency is improved, and key
technical support is provided for large-scale urban unmanned aerial vehicle logistics operation.
