Embodiment 1
[0028] Choose 100 pagoda tree seeds, in an area of 2500m 2 On the land with a plant spacing of 5 meters, sowing is carried out according to the following method:
[0029] 1) The setting of the flight route, setting the flight route of the UAV over the area to be sown before the UAV takes off;
[0030] 2) The setting of the seed launch frequency, according to the plant spacing of the plant seeds to be put in, set the seed launch frequency to be 2 per second;
[0031] 3) The setting of the flight speed of the UAV, according to the plant spacing and the launch frequency of the plant seeds to be dropped, the flight speed of the drone is set as: flight speed = launch frequency * plant spacing, that is, the flight speed is set to 10m / s;
[0032] 4) The UAV takes off and sows, the UAV flies according to the preset route, and the seed capsule sows according to the preset launch frequency.
[0033] After sowing, the plant spacing between 10 groups of plant seeds was randomly sele...
Embodiment 2
[0037] Choose 200 poplar seeds, in an area of 8000m 2 Sowing on the land with a plant spacing of 6 meters is carried out as follows:
[0038] 1) The setting of the flight route, setting the flight route of the UAV over the area to be sown before the UAV takes off;
[0039] 2) The setting of the seed launch frequency, according to the plant spacing of the plant seeds to be put in, set the seed launch frequency to be 2 per second;
[0040] 3) The setting of the flight speed of the UAV, according to the plant spacing and the launch frequency of the plant seeds to be dropped, the flight speed of the drone is set as: flight speed = launch frequency * plant spacing, that is, the flight speed is set to 12m / s;
[0041] 4) The UAV takes off and sows, the UAV flies according to the preset route, and the seed capsule sows according to the preset launch frequency.
[0042] After sowing, the plant spacing between 20 groups of plant seeds was randomly selected for measurement, and the...

Abstract
The invention provides an unmanned aerial vehicle automatic planting method and relates to the field of unmanned aerial vehicle automatic seeding in forestry and agriculture. The unmanned aerial vehicle automatic planting method comprises the following steps: 1) setting a flight path, namely setting a flight path of an unmanned aerial vehicle over a seeding required area before the unmanned aerialvehicle takes off; 2) setting a seed launching frequency, namely setting the seed launching frequency according to inter-plant distances of plant seeds to be launched; 3) setting the flight speed ofthe unmanned aerial vehicle, namely setting the flight speed of the unmanned aerial vehicle to be equal to a product of the launching frequency and the inter-plant distance according to the inter-plant distances of the plant seeds to be launched and the launching frequency; and 4) enabling the unmanned aerial vehicle to take off and seed, namely enabling the unmanned aerial vehicle to fly along apreset path, and seeding in a seed cabin according to the preset launching frequency. According to the method disclosed by the invention, by setting a matching relationship between the flight speed ofthe unmanned aerial vehicle and the launching frequency of the seeds, the distance controllability between the seeds can be ensured, so that resources are saved, and the plantation effect is improved.
Description
technical field [0001] The invention relates to the field of automatic seeding by drones in forestry and agriculture, in particular to an automatic forestation method by drones. Background technique [0002] The traditional agricultural and forestry UAV aerial seeding afforestation method uses the UAV to carry a large number of seeds to fly over the operation area, open the seed hatch door, and directly drop the seeds at one time. [0003] At present, the existing UAV-spreading aerial sowing technology is suitable for UAVs to mount pods with exposed seeds, open the outlet of the seed pods after lifting off, and the seeds will fall to the ground under the action of gravity. [0004] There are still some deficiencies in the above-mentioned technical solution: 1. Directly placed in disorder, many coordinate points may fall into multiple seeds, resulting in waste of resources; 2. The distance between some tree species is too large, and the effect of afforestation and wind and sa...
