[0021] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0022] In the present invention, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0023] See also Figure 1-2 The vision-based drone management system shown includes a terminal server, a global drone and multiple terminal drones. The global drone is connected to the terminal server via a wireless signal and is used to collect global floating object 10 position information through a first visual camera and feed back the floating object 10 position information to the terminal server. The terminal drone is connected to the terminal server via a wireless signal and is used to fly to a specified position and height according to the collected floating object 10 position information to grab the floating object 10 ashore.

[0024] The drone management system can perform global control based on vision, efficiently clean up the floating objects 10 on the lake surface, and increase the cleaning efficiency of the floating objects 10 on the lake surface. When performing the cleaning operation of floating objects 10 on the lake surface: first start the global drone to scan above the lake surface, roughly locate the position of the floating objects 10 to obtain the position coordinate range, and then send the collected global floating object 10 position information to the terminal server, and the terminal server distributes the position information of the floating objects 10 to multiple terminal drones for grabbing and executing, and the terminal drone flies to the assigned position coordinates to grab the corresponding floating objects 10, grabs the grabbed floating objects 10 to the designated recovery position on the shore, and finally flies back to the landing position.

[0025] In this embodiment, the global drone is provided with multiple devices, and all of them are located in a set area for cruising, and each of the global drones is matched with multiple terminal drones. Through such a setting, multiple global drones are provided, which can be used in areas with larger lake areas.

[0026] In this embodiment, in order to further provide a terminal drone, the terminal drone includes: a drone body 1; four second visual cameras 6 arranged in a rectangular shape around the bottom of the drone body 1; a grab module installed in the middle of the bottom of the drone body 1; and a cruise camera 2 installed at the front end of the drone body 1. The cruise camera 2 is used to assist in circular flight. When the terminal drone flies to the approximate position of the floating object 10, the four second visual cameras 6 are used to accurately locate the floating object 10, thereby overcoming the short-distance displacement problem of the floating object 10 caused by environmental reasons.

[0027] In this embodiment, in order to further provide a grabbing module, the grabbing module includes: two groups of grabbing units symmetrically arranged front and back or left and right; the front end of the grabbing unit is provided with a swingable grabbing plate 7; the sides of the two grabbing plates 7 facing each other are provided with a pressing part. By setting the two symmetrically arranged grabbing units, the balance of the UAV flight can be better controlled. When grabbing, the grabbing plates 7 are rotated to make the grabbing plates 7 approach or move away from each other, so as to realize the release of the grabbing of the floating object 10.

[0028] In this embodiment, the pressing part is a needle 9 or a friction plate. When the first visual camera recognizes the floating object 10, it collects the image information of the floating object 10 to the terminal server, and the terminal server obtains the shape characteristics corresponding to the floating object 10 through analysis, and selects the corresponding pressing part according to the material of the floating object 10. For example, when the floating object 10 is a soft and thin cloth-like object or a woven fabric, the needle 9 can be used as the pressing part.

[0029] In this embodiment, in order to further provide a grasping unit, the grasping unit includes a U-shaped frame 11 with an opening facing downward; the upper end of the U-shaped frame 11 is hinged with a cylinder 5, and the lower end is hinged with the grasping plate 7; the back of the pressing part is provided with a vertical seat 8; the lower end of the cylinder 5 is hinged with the vertical seat 8. The extension of the cylinder 5 pushes the lower ends of the two grasping plates 7 to approach each other, thereby achieving grasping.

[0030] In this embodiment, a telescopic rod 3 is provided between the U-shaped frame 11 and the drone body 1. By providing the telescopic rod 3, the flying height problem of the drone body 1 can be compensated, so that the drone body 1 can stay at a higher position from the water surface for grabbing.

[0031] In this embodiment, a ranging radar 4 is disposed at the bottom center of the drone body 1. The ranging radar 4 can more accurately control the distance between the drone body 1 and the target floating object 10, thereby achieving more accurate capture.

[0032] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0033] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0034] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
