The invention discloses a multi-scale grid-based middle and
low altitude space resource matching method, which comprises the following steps of: firstly, constructing a 5D (5-dimensional) universal
grid system comprising a
geographic space dimension, a time dimension and a frequency dimension, and distributing a unique multi-dimensional code identifier for each grid unit; therefore, unified and standardized digital description of the urban low-altitude environment is realized. On this basis, a multi-scale grid is constructed through a dynamic grid
granularity adjustment mechanism, and in an open airspace, coarse-grained grid nodes are selected to quickly guide a global track; and in a dense airspace, switching to a fine-grained grid node to carry out accurate
obstacle avoidance and local track optimization. Then, based on the 5D multi-scale grid, the planned
route of the detection platform and the working platform is mapped into a
route grid changing along with time; and the feasibility and conflict risk of the resource matching link are judged by accurately calculating the intersection of the
air line grids in the space-time and frequency dimensions. And finally, constructing an optimization model which aims at maximizing the
overall efficiency of air
resource utilization, and dynamically allocating a detection platform and an operation platform by using a meta-
heuristic algorithm to realize
intelligent planning and real-time optimization of an air
route. According to the invention, digital and
intelligent management of the middle-low-altitude airspace is realized, and the
resource utilization rate and cooperation efficiency of the middle-low-altitude airspace are effectively improved.
