[0002] With the continuous development and progress of science and technology, two-dimensional graphics and image data can no longer meet the needs of people's daily production and life. After continuous development, three-dimensional visualization technology and related supporting equipment have also been gradually improved. Using three-dimensional visualization technology can more intuitively, conveniently and accurately show the real situation.

[0003] Currently, 3D laser scanning equipment is supported by tripods. However, existing tripods only serve a supporting function. If the 3D laser scanning equipment needs to be moved, the staff must carry the entire equipment, which is cumbersome and inconvenient for moving the 3D laser scanning equipment. In addition, the existing 3D laser scanning equipment has few protective structures, making it easy to be damaged during storage and transportation. There is an urgent need to design a 3D laser scanning equipment that integrates spatial positioning to solve the above problems. Utility Model Content

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown in the figure, this utility model provides a three-dimensional laser scanning device that integrates spatial positioning.

[0022] The system includes a support platform 1, with two fixed plates 2 mounted on its top. A rotating plate 3 is rotatably connected between the two fixed plates 2. A three-dimensional laser scanning device body 4 is mounted on the top of the rotating plate 3. A satellite orientation and positioning device 5 is mounted on the top of the three-dimensional laser scanning device body 4. Three telescopic rods 6 are rotatably connected to the bottom of the support platform 1. The three telescopic rods 6 are arranged in a circular array. Insert rods 7 are rotatably connected to the bottom ends of the telescopic rods 6. A fixed rod 8 is mounted on the bottom of the fixed rod 8. A movable base 9 is mounted on the bottom of the movable base 9. A movable wheel 10 is rotatably connected to the bottom of the movable base 9. Three slots 11 corresponding to the three insert rods 7 are opened on the periphery of the movable base 9. An auxiliary wheel 12 is provided at one end of each of the three insert rods 7. Protective plates 13 are slidably connected to both sides of the rotating plate 3. The protective plates 13 are snap-fitted into the support platform 1.

[0023] Among them, the satellite orientation and positioning device 5 includes a GNSS positioning module. The scanner integrates the global navigation satellite system and obtains centimeter-level absolute position coordinates through real-time dynamic differential method. The module supports RTK positioning and 4G base station positioning. A global coordinate system is established through known control points. The built-in sensor of the scanner automatically adjusts the attitude, and the automated target recognition and stitching reduces manual intervention.

[0024] Reference Figure 2 In this embodiment, the telescopic rod 6 includes a connecting block 14 installed at the bottom of the support platform 1, a rotating cylinder 15 rotatably connected to the connecting block 14, a sliding rod 16 slidably fitted inside the rotating cylinder 15, and a fixing bolt 17 disposed on one side of the rotating cylinder 15, the fixing bolt 17 abutting against the sliding rod 16. The rotating cylinder 15 allows one end of the rotating cylinder 15 to rotate within the connecting block 14, which restricts the rotation angle of the rotating cylinder 15. The sliding rod 16 is then pulled out from the rotating cylinder 15 and fixed using the fixing bolt 17, thus adjusting the equipment support height.

[0025] Reference Figure 2 In this embodiment, three mounting rods 18 are provided around the fixed rod 8. One end of each mounting rod 18 is provided with a clamp 19, and the three clamps 19 are respectively engaged with three rotating cylinders 15. Through the clamps 19, when the telescopic rod 6 is rotated and retracted, the rotating cylinder 15 will engage with the clamps 19, so that the clamps 19 fix and store the rotating cylinder 15.

[0026] Reference Figure 3 In this embodiment, the bottom end of the slide rod 16 has a groove 20, and the insertion rod 7 is rotatably fitted within the groove 20. One end of the insertion rod 7 is provided with an extension rod 21, and the auxiliary wheel 12 is rotatably fitted at the bottom of one end of the extension rod 21. Both sides of the groove 20 are provided with elastic sleeves 22, which engage with the extension rod 21. Through the elastic sleeves 22, when the insertion rod 7 is rotated out for support and fixation, the extension rod 21 engages with the two elastic sleeves 22, retracting the auxiliary wheel 12 and fixing the insertion rod 7.

[0027] Reference Figure 4 In this embodiment, sliders 23 are provided on both sides of the rotating plate 3, and grooves 24 are provided on opposite sides of the two protective plates 13. The two sliders 23 slide in contact with the two grooves 24 respectively, and both the sliders 23 and the grooves 24 are T-shaped. By using the sliders 23, when the protective plate 13 is moved, the sliders 23 move along the grooves 24, making the up-and-down movement of the protective plate 13 more stable and limiting the left-and-right rotation of the protective plate 13.

[0028] Reference Figure 4In this embodiment, pull rods 25 are installed on the two outer sides of the two protective plates 13. Elastic locking plates 26 are provided at the top and bottom of both protective plates 13. Two slots 27 corresponding to the two protective plates 13 are provided at the top of the support platform 1. The elastic locking plates 26 at the top and bottom of the protective plates 13 engage with one slot 27. By pulling the pull rods 25 through the elastic locking plates 26, the protective plates 13 are moved, causing the elastic locking plates 26 at the bottom of the protective plates 13 to engage with the slots 27 at the top of the support platform 1, thus fixing the rotating plate 3 and keeping it horizontal. After the rotating plate 3 is flipped, the elastic locking plates 26 at the top of the protective plates 13 can engage with the slots 27 at the top of the support platform 1.

[0029] Working Principle: In use, first rotate the three telescopic rods 6 to adjust their lengths. Then, use the insert rod 7 to fix the entire device, allowing the three telescopic rods 6 to support the support platform 1. Next, pull the two protective plates 13 upwards to release the locking mechanism between the protective plates 13 and the support platform 1. Then, move the rotating plate 3 to rotate the 3D laser scanning equipment body 4. After rotating half a turn, the 3D laser scanning equipment body 4 and the satellite orientation and positioning device 5 are moved out. Then, pull down the two protective plates 13 to lock them into place with the support platform 1, fixing the rotating plate 3 and the 3D laser scanning equipment body 4 in place. The satellite orientation and positioning device 5 obtains centimeter-level absolute position coordinates in real-time using the dynamic differential method. The scanner uses the control points as a reference for... Relative positioning ensures the authenticity and reliability of the collected data. When the mobile device needs to be moved, the 3D laser scanning device body 4 can be stored first. Pull the two protective plates 13 upward to release the latch, and rotate the rotating plate 3 to retract the 3D laser scanning device body 4, so that the 3D laser scanning device body 4 and the satellite orientation positioning device 5 are located between the two fixed plates 2. Then pull down the two protective plates 13 to latch with the support platform 1 to store and protect the device. After storage, the three telescopic rods 6 are retracted, and the insertion rod 7 at one end of the telescopic rod 6 is inserted into the corresponding slot 11. At this time, the auxiliary wheel 12 at one end of the insertion rod 7 is moved out, so that the three auxiliary wheels 12 support and assist one moving wheel 10, which can push the device to move stably through the moving wheel 10 and the three auxiliary wheels 12.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
