Problems solved by technology

[0002] The application of drones in plant protection is becoming more and more extensive. Since the plant protection drones are equipped with a positioning system, when the plant protection drones return and land, they use the take-off point as the landing point. If there are obstacles at the landing point, and If the obstacle is not dealt with in time, the plant protection drone will collide with the obstacle when it lands, which will cause certain property losses. If someone is at the landing point and the plant protection drone does not avoid the obstacle in time, then people's Personal safety will be threatened and irreparable losses will be caused, which is also a huge challenge for operators

Embodiment 1

[0023] see figure 1 , the present invention provides a technical solution: a method for plant protection drones to return and land for obstacle avoidance, the plant protection drone includes a drone body and a ranging device and a camera installed under the drone body, The ranging device is a radar, an ultrasonic sensor or a laser sensor, and a horn is arranged above the drone body, and the method includes the following steps:

[0024] S1: The distance measuring device measures the height h between the plant protection UAV and the landing point;

[0025] S2: The camera collects images of the landing area of ​​the plant protection drone;

[0026] S3: The image processing module on the plant protection drone performs data analysis on the collected images;

[0027] S4: Determine the actual area of ​​the safe landing of the plant protection drone in the landing area;

[0028] S5: Remind the operator to remove obstacles in the landing area through the horn;

[0029] S6: The pla...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that the S5 is that the plant protection drone independently sets a new landing point or artificially sets a new landing point;

[0037] The plant protection drone independently sets a new landing point, including: according to S4, the difference between the actual area S of the plant protection drone's safe landing and the plane area of ​​the plant protection drone can be calculated, and then calculated by an algorithm according to the difference Find a new landing point, and the plant protection drone flies to the new landing point for a safe landing;

[0038] The artificial setting of a new landing point includes the operator controlling the plant protection drone through the ground terminal, so that the plant protection drone can land safely.

Abstract

The invention discloses a method for avoiding obstacles by returning and landing a plant protection drone. The plant protection drone includes a drone body and a ranging device and a camera installed under the drone body. The drone A horn is provided above the body, and the method includes the following steps: S1: the distance measuring device measures the height h between the plant protection drone and the landing point; S2: the camera collects images of the plant protection drone's landing area; S3: the plant protection drone The image processing module on the man-machine performs data analysis on the collected images; S4: Determine the actual area where the plant protection drone can safely land in the landing area; S5: Remind the operator (owner) to remove obstacles in the landing area through the horn ; S6: The plant protection drone landed safely. The invention accurately judges the safety of the plant protection drone when it lands in the landing area through the combined use of the ranging device and the camera, thereby reducing the accident rate of the plant protection drone and ensuring people's personal safety and property safety.

Description

technical field [0001] The invention relates to the technical field of UAV obstacle avoidance, in particular to a method for plant protection UAV return and landing obstacle avoidance. Background technique [0002] The application of drones in plant protection is becoming more and more extensive. Since the plant protection drones are equipped with a positioning system, when the plant protection drones return and land, they use the take-off point as the landing point. If there are obstacles at the landing point, and If the obstacle is not dealt with in time, the plant protection drone will collide with the obstacle when it lands, which will cause certain property losses. If someone is at the landing point and the plant protection drone does not avoid the obstacle in time, then people's Personal safety will be threatened and irreparable losses will be caused, which is also a huge challenge for operators.
