Concave Polygon Decomposition
The algorithm tackles complex forest areas by decomposing irregular concave polygons into manageable convex sub-regions. This is crucial for optimizing UAV flight paths, minimizing turns, and reducing energy consumption. The method employs a selective concave point removal strategy based on area ratio and external angle thresholds, reducing computational complexity and preventing invalid coverage areas.
Multi-UAV Region Allocation
To ensure balanced task distribution and spatially contiguous coverage, a novel region allocation method is proposed. This method sorts triangular sub-regions by spatial position (centroid coordinates) and uses an area accumulation strategy with explicit adjacency constraints. This ensures fairness and balance in task allocation across multiple UAVs, crucial for large-scale operations.
Real Terrain Validation & Altitude Optimization
The solution incorporates real terrain data (DEM) and a slope shading model to dynamically adjust flight altitude. This optimizes the UAV's field of view, minimizes occlusion, and balances detection accuracy with coverage efficiency, particularly vital for undulating forest landscapes. Experiments confirmed that an optimal flight height (e.g., 150m) significantly boosts coverage rate and reduces shading.
Comparative Efficiency Analysis
Compared to single UAV operations and other existing methods, the proposed multi-UAV cooperative strategy demonstrates superior performance. It significantly reduces total coverage time and path length, minimizes redundant paths, and maintains a balanced task allocation. This translates directly to lower operational costs and faster data acquisition for forest monitoring.

Case Study: Xishuangbanna Rainforest Monitoring
The proposed multi-UAV system was validated using real terrain data from the Xishuangbanna rainforest in Yunnan Province. Facing a maximum slope angle of 25° and average elevation difference of 150m, the system dynamically optimized flight altitude. At an altitude of 150m, the lowest occlusion coefficient of 0.09 was achieved, alongside a high coverage rate of 97.8% and a reduced path length of 265.2 km. This demonstrates the algorithm's robustness and efficiency in complex, real-world forest environments for applications like fire monitoring and pest identification.
