Design and Implementation of Evaluation Method for Spraying Coverage Region of Plant Protection UAV

Plant protection UAVs are becoming the preferred plant method for agricultural pest control. At present, evaluation of droplet distribution in aerial spraying is collected and evaluated after completion prevention control operations, there a lack real-time methods. Based on flight parameter during UAV process, estimation key to solving this problem further improving effectiveness spraying. This study proposes merging algorithm arbitrary polygonal regions, meshing boundaries region, divide mesh segments based overlapping meshes between two connect valid connection regions according certain rules obtain intersection, union, residual operation results regions. Afterwards, software was developed applied generate coverage leakage spray repeated The experimental theoretical irregular routes show that can accurately error calculation with scale 0.05 m within 7‰, operating speed above 30 Hz, meeting requirements. smaller is, higher accuracy but slower speed. Therefore, practical applications, it necessary choose an appropriate hardware computing power level solves cumulative UAVs, providing basis objectively evaluating quality optimizing setting parameters.
