Embodiment Construction

[0086] In order to further explain the above technical solutions and actual effects, the following will be described in detail below.

[0087] Get grid to a two-dimensional aerial matrix A for a certain airspace. Such a two-dimensional airspace matrix may come from a three-dimensional map, extract a height of a high layer of a height in a three-dimensional map, and it is obtained after the corresponding evaluation is assigned. Or from the processed satellite image. Considering the size of the drone and the speed of the drone, the rasterization resolution should not exceed 1M × 1m. Because too high resolution not only does not bring more detail processing, it will reduce the algorithm speed because the airspace matrix is ​​too large. The map is binaryized to 0-1 matrix. like Figure 8A It is a two-standard airspace, a resolution of 10m × 10m.

[0088] like Figure 8B In the airspace map, a certain target point is randomly, with a black cross identity.

[0089] like Figure 8C Artifici...

Abstract

The invention discloses an unmanned aerial vehicle route network automatic generation method considering a specific network structure. The method comprises the steps of converting an evaluation value of a specific low-altitude airspace environment into a binary airspace digital map representing the airspace condition; according to the airspace digital map condition and target point setting, selecting a dense area of a no-fly zone through manual framing, carrying out certain processing, and respectively generating two parts of a suitable air route network inside and outside the framing zone; connecting the two parts of the air route network, and reducing the scale of the air route network; carrying out conflict detection between the specific structure of the air route network and the airspace, and labeling so as to facilitate manual adjustment; and when the unmanned aerial vehicle traffic network is generated, extracting a map representing the network topology structure. According to the invention, automatic unmanned aerial vehicle route network generation can be realized, efficient and orderly traffic of a large amount of unmanned traffic is ensured, and the network cost is saved at the same time. The topological structure of the air route network is extracted synchronously, so that wider application is facilitated.

Description

Technical field [0001] The present invention belongs to the field of drone technology, and specifically, an automated unparalleled automatic road network generation method, in particular a method of automatic generation method for unmanifestinal road network considering specific network structures and complex space domain. Background technique [0002] The aircraft gets more broad applications in many areas, such as patrol, mapping, field information monitoring, drug spray, express delivery and pipeline inspection. However, with the gradual expansion of the drone application, the number of applications is gradually rising, and the unordered low-altitude flight of the drone will bring greater risk and inefficiency. And there is currently no ready-to-use traffic approach to drones to migrate applications, and need to design a transport route network for drones to be designed. Therefore, it is focused on the way to generate a route network generating method suitable for drone traffi...
