Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only considered for the purpose of illustration rather than limitation of the invention.
[0033] Embodiments of the present invention provide a graph network construction method oriented to visibility analysis and application modeling, the purpose of which is to divide the optimization modeling problem of terrain visibility analysis application into two steps to complete. Convert the field model data of the digital elevation model into graph data expressed by a graph model, and then optimize modeling and model solution based on the graph model. The advantage of this is that it can simplify the complexity of modeling and the efficiency of model solving.
[0034] For example, in the path planning problem based on visibility analysis, the digital elevation model is first converted into a graph network model, an...
