Making every drone flight safe and intelligent

DroneDetour is a Java-based library with an Android demo that implements an intelligent UAV detour path planning algorithm.
It enables autonomous drones to calculate the shortest safe flight route around multiple polygonal no-fly zones, ensuring reliable navigation even under GPS-degraded or restricted environments.

• 🚫 Support for multiple polygonal no-fly zones
• 🧭 Automatic shortest detour route calculation
• ⚙️ Configurable safeBuffer (e.g., 10 meters)
• 📱 Android demo for visualization and testing
• 💡 Pure Java library — easy to integrate into flight control or simulation systems

Copy the lib_detour module into your project.

  List<MyLatLng> noFlyZone = new ArrayList<MyLatLng>();
        noFlyZone.add(.);//no fly zone border point

List<List<MyLatLng>> noFlyZones = new ArrayList<List<MyLatLng>>();
        noFlyZones.add(noFlyZone);
//1. update no fly zones
        DetourPathManager.getsInstance().updateNoFlyZones(noFlyZones);
//2. calculate the shortest detour path 
MyLatLng startPoint = new MyLatLng(36.1234132, 120.333345);
MyLatLng endPoint = new MyLatLng(36.1234132, 120.333345);
//3. get the detour path
List<MyLatLng> detourPath = DetourPathManager.getsInstance().calculateDetourPath(List.of(startPoint, endPoint));
