[0026] As Figure 1 And Figure 2As shown, the utility model discloses a portable unmanned aerial vehicle ground target device, including capsule mechanism and launch mechanism, capsule mechanism includes capsule body 1, support rod 6, high pressure gas cylinder 2 and tow rope 9, the top of support rod 6 is connected with the bottom of capsule body 1, high pressure gas cylinder 2 is arranged in capsule body 1, the exhaust port of high pressure gas cylinder 2 is communicated with the internal cavity of capsule body 1, and the internal cavity of capsule body 1 is equipped with identification pigment, specifically, capsule body 1 is equipped with identification pigment containing cavity, and identification pigment is arranged in identification pigment containing cavity, and high pressure gas cylinder 2 is arranged at the bottom of capsule body 1, the bottom of capsule body 1 is equipped with containing cavity, and high pressure gas cylinder 2 is arranged in containing cavity, and the exhaust port of high pressure gas cylinder 2 is communicated with identification pigment containing cavity;

[0027] One end of tow rope 9 is connected with the exhaust switch of high pressure gas cylinder 2, and the specific structure of high pressure gas cylinder 2 is same with the cylinder structure used on automatic air inflation life jacket in prior art, and the specific structure will not be repeated here, and the exhaust switch of high pressure gas cylinder 2 can be opened by dragging tow rope 9, and high pressure gas cylinder 2 fills high-pressure gas into identification pigment containing cavity, so that capsule explodes and sprays identification pigment;

[0028] The launch mechanism can be designed according to the existing bow and arrow structure, specifically, the launch mechanism includes a crossbow arm 7, a crossbow bow 12, a bowstring 13 and a trigger mechanism 10, the crossbow bow 12 is installed on the crossbow arm 7, the two ends of the bowstring 13 are connected with the two ends of the crossbow bow 12 respectively, the crossbow arm 7 is provided with a guide groove 8 along the length direction, the guide groove 8 is used for accommodating the support rod 6, the trigger mechanism 10 is arranged on the crossbow arm 7, the trigger mechanism 10 can adopt the trigger mechanism structure of the existing bow and arrow, the trigger mechanism 10 can also adopt the form that the motor drives the lever to rotate, when the motor driving mode is adopted, the control can be realized through the remote control mode, so as to avoid that the identification pigment of the capsule body 1 is splashed on the operator when the capsule body 1 explodes, and one end of the tow rope 9 away from the high pressure gas cylinder 2 is connected with the crossbow arm 7.

[0029] In the embodiment, it should be noted that the identification pigment adopts degradable pigment, the identification pigment is mixed with foliar fertilizer, and the identification pigment is pink or magenta, the two colors of pigment have the maximum difference with the green gray scale of the vegetation canopy in the image gray scale, and the difference is also obvious when visible light is recognized. The foliar fertilizer and the pigment not only do not destroy the forest canopy, but also help the growth of leaves due to the contained nutrients;

[0030] The capsule mechanism adopts disposable product design, and does not need recycling after launching, and the capsule body 1, the support rod 6 and the tow rope 9 are all made of degradable materials;

[0031] The high pressure gas cylinder 2 is filled with inert gas, and the capsule body 1 is supported and exploded by high-pressure gas in the use process, and there is no risk of causing forest fire in the explosion process of the capsule body 1, which is more safe and reliable;

[0032] The traction rope 9 can be folded and bent multiple times and has a rough scale (such as meters) to facilitate setting the height at which the capsule body 1 is blown open before use. Generally, the length of the guide wire is controlled within 30 meters, which can cover most of the height of the dense forest.

[0033] Further, the specific use mode of the whole device is as follows. During use, the capsule mechanism can be launched to the forest canopy layer by the launching mechanism. The specific height reached by the capsule mechanism is controlled by the length of the traction rope 9. Generally, the launch height of the capsule mechanism is more than three meters above the tree crown height. After the capsule mechanism reaches the specified height, it still has a tendency to move upward, but it cannot move due to the length limitation of the traction rope 9. The traction rope 9 will drag the opening of the high-pressure cylinder 2 to make the capsule body 1 inflate and then blow open to spray the marking pigment to form a circle with a diameter of 3m to 5m. After the marking pigment settles on the tree crown, a certain area of the marking area is formed as the crown target for aerial photography and surveying of the unmanned aerial vehicle. The crown target can be used as a ground phase control point for the unmanned aerial vehicle to identify. After use, the traction rope 9 is cut off to discard the whole capsule mechanism. The capsule mechanism is disposable and does not need to be recycled. During use, only one launching mechanism and multiple capsule mechanisms need to be carried to complete the target operation at multiple positions.

[0034] The technical effect achieved by the embodiment is that the tree crown can form the crown target for aerial photography and surveying of the unmanned aerial vehicle as the ground phase control point for the unmanned aerial vehicle to identify, and a clear identification mark can be formed in the image. By measuring the coordinate information of the target, the accurate coordinate of the position identified by the target can be obtained, which provides accurate position corresponding information for image stitching and registration in the later period. The whole device has a compact structure, is suitable for carrying and use in dense forest areas, has low use cost, and is simple to operate and easy to popularize. The dependence of the phase control point for aerial survey of the unmanned aerial vehicle on open, unobstructed and shadowless sites is overcome, the problem of reasonable layout of the phase control point in the dense forest area is solved, and the working intensity of the ground phase control point layout personnel is greatly reduced.
