[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0022] like Figure 1-5 As shown, the present invention proposes a mapping drone positioning and tracking device, including a camera 1 and a support assembly 2. The support assembly 2 includes a tripod 3 and a fixed base 4. The fixed base 4 is provided with a height adjustment component 5. An L-shaped bracket 6 is movably connected to the top of the height adjustment component 5. A rotating shaft 7 is rotatably provided on the side wall of the L-shaped bracket 6. A connecting sleeve 8 is provided on the side wall of the camera 1. The connecting sleeve 8 is fixed to the rotating shaft 7 by bolts. The height of the camera 1 can be adjusted by adjusting the height adjustment component 5. The tracking position of the camera 1 can be adjusted by rotating the L-shaped bracket 6. The pitch angle of the camera 1 can be adjusted by rotating the rotating shaft 7.
[0023] like Figure 2 As shown, the height adjustment component 5 includes a support cylinder 9 and a sliding rod 10. The support cylinder 9 is disposed through the fixed base 4. The bottom of the sliding rod 10 is slidably disposed inside the support cylinder 9. The support cylinder 9 is threadedly connected to a fastening bolt 11. The sliding rod 10 is provided with several screw holes 12. The fastening bolt 11 is threadedly connected to the screw holes 12. By loosening the fastening bolt 11, the sliding rod 10 can be slid to adjust the height of the camera 1.
[0024] like Figure 3-4 As shown, the top of the slide rod 10 is provided with a connecting plate 13, and a connecting shaft 14 is rotatably provided on the connecting plate 13. The bottom wall of the L-shaped bracket 6 is fixed on the connecting shaft 14, and a worm gear 15 is fixed on the connecting shaft 14. A support plate 16 is provided on the connecting plate 13, and a worm 17 is rotatably provided on the support plate 16. The worm 17 is connected to the worm gear 15. A handle 18 is rotatably provided on the support plate 16. The end of the handle 18 rotatably passes through the support plate 16 and is connected to the worm 17. Rotating the handle 18 drives the worm 17 to rotate, which in turn drives the worm gear 15 to rotate. The worm gear 15 drives the connecting shaft 14 to rotate, thereby adjusting the position of the camera 1.
[0025] like Figure 5 As shown, the tripod 3 includes three circumferentially distributed support cylinders 19 and support legs 27. The top of the support cylinder 19 is hinged to the fixed base 4. The support legs 27 are slidably mounted on the support cylinder 19. The bottom of the support legs 27 is provided with anti-slip pads 26. The support cylinder 19 is threaded with a second fastening bolt 20. The support legs 27 are provided with several second screw holes 21. The support cylinder 9 is slidably fitted with a sliding sleeve 22. A connecting arm 23 is hinged between the sliding sleeve 22 and the support cylinder 19. The sliding sleeve 22 is threaded with a third fastening bolt 24 that tightens the support cylinder 9. The second fastening bolt 20 is threadedly connected to the second screw hole 21. By rotating the second fastening bolt 20, the extension of the support legs 27 can be adjusted to assist in height adjustment or leveling.
[0026] like Figure 5 As shown, the L-shaped bracket 6 is threaded with a fastening bolt 25. The bottom end of the fastening bolt 24 presses against the rotating shaft 7. Loosening the fastening bolt 25 allows the rotating shaft 7 to rotate, thereby adjusting the pitch angle of the camera 1.
[0027] In practical use, place the device at the survey location and observe whether the device is level. If it is not level, rotate the second fastening bolt 20 and adjust the extension length of the support leg 27 to make the device level. At the same time, the foundation height can be adjusted by adjusting the extension length of the support leg 27 according to the approximate survey height requirements. After the adjustment is completed, tighten the second fastening bolt 20 to fix the position of the support leg 27.
[0028] Loosen the fastening bolt 11 on the support cylinder 9, and slide the slide bar 10 up or down according to the actual height of the target being surveyed, thereby adjusting the height of the camera 1. After adjusting to the appropriate height, thread the fastening bolt 11 into the corresponding screw hole 12 on the slide bar 10, and tighten the fastening bolt 11 to fix the height of the camera 1.
[0029] Rotate handle 18, which drives worm gear 17 to rotate. Worm gear 17 cooperates with worm wheel 15, which drives worm wheel 15 to drive connecting shaft 14 to rotate, thereby causing L-shaped bracket to rotate and realize the adjustment of camera 1 tracking position. After adjusting camera 1 to a suitable position according to the direction of the survey target, stop rotating handle 18.
[0030] Loosen the fastening bolts 425 on the L-shaped bracket, rotate the shaft 7, and drive the connecting sleeve 8 and camera 1 to adjust the pitch angle. When the pitch angle of camera 1 meets the surveying requirements, tighten the fastening bolts 425 to fix the shaft 7, thereby fixing the pitch angle of camera 1.
[0031] Once the drone enters the field of view, smooth azimuth tracking can be performed using handle 18. If large-scale movement tracking is required, Z-axis compensation can be performed simultaneously using the altitude adjustment mechanism.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
