The method comprises the following steps: acquiring a water surface image on the water surface by using an unmanned aerial vehicle, identifying and positioning blue-green algae at the initial stage based on the water surface image, and determining a blue-green algae distribution area in the water surface image; according to the shape and size of a blue-green algae distribution area in the water surface image, determining an algae killing bomb putting position; the unmanned aerial vehicle loaded with the algae killing bombs is used for throwing the algae killing bombs in a hovering mode at the algae killing bomb throwing position, and the algae killing bombs are used for inhibiting growth of blue-green algae. According to the invention, the unmanned aerial vehicle technology is utilized to monitor and early warn the sporadic cyanobacteria on the water surface and put the algae killing bombs, the growth process of the cyanobacteria can be intervened in time in the early stage of the outbreak of the cyanobacteria, mass propagation and outbreak of the cyanobacteria are restrained, the labor force can be reduced, the treatment efficiency is improved, and the treatment cost is reduced.

    本发明公开了一种蓝藻爆发初期的无人机投弹灭藻方法,利用无人机在水面上采集水面图像,基于水面图像进行初期蓝藻识别定位,确定水面图像中的蓝藻分布区域;根据水面图像中蓝藻分布区域的形状大小,确定灭藻弹投放位置;利用装载有灭藻弹的无人机,在灭藻弹投放位置处悬停投放灭藻弹,利用灭藻弹抑制蓝藻生长。本发明利用无人机技术对水面上早期呈零星分布的蓝藻进行监测预警和投放灭藻弹,能够在蓝藻爆发初期及时干预其生长过程,遏制蓝藻大量繁殖爆发,能够减少工作劳动力、提高治理效率、降低处理成本。
