Drone Intelligent UAV path planning simulation system is a software with fine operation control, strong platform integration, omnidirectional model building and application automation. It takes the UAV war between A and B in Zone C as the background. The core function of the system is to plan the UAV route through the simulation platform and verify the output. The data can be imported into the real UAV to make it accurately arrive at any position in the battlefield according to the specified route and support the joint action of multi-person and multi-device formation.
System supported by open source SITL uav simulation platform, through FlightGear rendering real battlefield environment, integrated modeling, 2 d vertical, three-dimensional dynamic model simulation, script control, ground station monitoring, data processing, and other functions, in addition, the simulation system supports a variety of global map load, simulate the key region of the three dimensional environment, can be used throughout the global remote sensing monitoring in the scene.

Indoor obstacle avoidance
Because the indoor structure has the characteristics of narrow space and many distractions, the path planning degree at this time focuses more on the effect of three-dimensional obstacle avoidance, and the map is meaningless. Based on Huiming Zhou's open source algorithm library, the indoor environment was created using the idea of modeling, and the 3D algorithms of Search_based_Planning and Sampling_based_Planning were used to plan the flight path for obstacle avoidance. The flight demo is as follows:

Search_3D_Indoor obstacle avoidance renderings
To optimize the flight paths of multiple UAV clusters, we add random, greedy, path optimal algorithm clustering, regional path random generation, regional path shortest distance first generation algorithm.
The algorithm generates the flight status of each UAV, the navigation point and the flight distance information

Solve The Problem
Intelligent UAV path planning simulation system solves the problem that ordinary UAV can not accurately plan the path, and ordinary UAV is not enough support, inconvenient to control, difficult to use in the actual war. This software can be designed for flight mission routes in advance, using a flight simulator unmanned aerial vehicle (uav) in the real-time state of mission, through strengthening unmanned aerial vehicle (uav) in the system against ground station module control, simulation of the unmanned aerial vehicle (uav) group of joint action tactical fighting, sailing and output data for the use of real unmanned aerial vehicle (uav), the uav size short, quick release, huge resource advantage as far as possible.
Application Scenarios And Benefits
Up to now, more than 40 countries are engaged in the research and production of UAVs, and more than 60 countries are using UAVs. The use of drones on the battlefield is the future of warfare.
The advantage of using this software is that it absorbs the results obtained abroad, recompiles and transplants the operating environment from Linux system to Windows and other operating systems, and uses Python language to write the program except the simulation 3D environment module. The program is easy to maintain and modify. The software interface prepared by PyQT5 integrates each module of the software, adds background prompt function, designs intelligent control scripts to simplify the use process of the system, and integrates FlightGear simulator and MissionPlanner ground station program for visualization, so as to improve the accuracy of real UAV flight path and specify flight plan as the fundamental purpose.

Mission Planner + Google Earth log generates 3D trajectory maps
Google China satellite map is used instead. It mainly imports the planned path generated by the Mission Planner or the console of the ground station to the map, with.waypoint or KMZ file as the main file.
