Description

Technical Field

[0001] This application relates to the field of three-dimensional data acquisition technology, and in particular to a mobile three-dimensional data acquisition device for large-space scanning. Background Technology

[0002] Mobile large-space scanning 3D data acquisition devices are primarily based on real-time localization and mapping (SLAM) technology. This technology does not rely on Global Navigation Satellite Systems (GNSS) for positioning, but instead enables self-positioning and incremental 3D mapping in unknown environments such as indoor and outdoor spaces. Using hardware devices such as laser scanners, structured light scanners, photogrammetry systems, or radar rangefinders, the device can acquire distance information, 3D shape information, or 3D models of object surfaces, thereby generating high-precision 3D point cloud data. In mobile large-space scanning 3D data acquisition devices, the data acquisition unit is one of the core components. It is responsible for receiving and processing raw data from the hardware devices and converting it into 3D point cloud data that can be used for subsequent analysis and applications.

[0003] A search revealed Chinese Patent Publication No. CN218032530U, which discloses a mobile device for real-scene 3D data acquisition. The device includes a base, a support leg on the top of the base, a binocular camera placement plate on the upper end of the support leg, a clamping mechanism on the binocular camera placement plate, casters fixed at the four corners of the lower end of the base, a plastic soft guide rail below the base, a support rod fixed at the end of the base, and a guide rail block fixed at the end of the support rod.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: since data acquisition devices are mostly installed using tripods, and because tripods are often too long vertically, operators often need to hold the tripod in one hand and carry the data acquisition device in the other, which is inconvenient. Therefore, to address the above problems, the applicant provides a mobile large-space scanning three-dimensional data acquisition device. Utility Model Content

[0005] To address the problems mentioned in the background section, this application provides a mobile large-space scanning 3D data acquisition device.

[0006] This application provides a mobile, large-space scanning 3D data acquisition device, which adopts the following technical solution:

[0007] A mobile large-space scanning three-dimensional data acquisition device includes a turntable and a storage mechanism. The storage mechanism consists of a storage bucket, a first insertion rod, a second insertion rod, a third insertion rod, a fourth insertion post, and a pin. The bottom surface of the storage bucket is fixedly connected to the first insertion rod. The first insertion rod is connected to the second insertion rod via a pin. The second insertion rod is connected to the third insertion rod via a pin. The third insertion rod is connected to the fourth insertion post.

[0008] The turntable is equipped with a lighting mechanism, which consists of a charging module and a lighting lamp. The charging module is electrically connected to the lighting lamp.

[0009] Optionally, the top of the storage bucket is provided with multiple pin placement slots, the bottom of the storage bucket has three through slots, and a sleeve is rotatably connected to the outer circumference of the storage bucket, with a "U"-shaped rod fitted in the sleeve.

[0010] Optionally, there are three of each of the first, second, third and fourth insertion rods, and each of the three first insertion rods is equipped with a caster wheel at the bottom.

[0011] Optionally, each of the three insertion rods has a through-hole, and the top and bottom of the insertion rods 2 and 3 each have a through-hole. The insertion post 4 has multiple through-holes 2 at equal intervals, and the insertion post 4 is engraved with scale values.

[0012] Optionally, the pin is inserted into the insertion hole one of the insertion rod one and the insertion hole one at the bottom of the insertion rod two, the insertion rod two passes through the through groove, the pin is inserted into the insertion hole one at the top of the insertion rod two and the insertion hole one at the bottom of the insertion rod three, and the pin is inserted into the insertion hole one at the top of the insertion rod three and one of the insertion holes one of the insertion post four.

[0013] Optionally, the tops of the three insertion posts are fixedly connected to a base, and a turntable is rotatably connected to the center of the base.

[0014] Optionally, the turntable has a charging module mounting slot, in which a charging module is installed. A serpentine tube is installed on the top of the turntable, and a lighting lamp is installed at one end of the serpentine tube.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. The storage mechanism of this utility model, by retracting the tripod into the first insertion rod, the second insertion rod, the third insertion rod, and the fourth insertion post in sequence, and simultaneously retracting the data acquisition device and the lighting mechanism into the storage bucket, avoids the inconvenience of the tripod being too long vertically, which requires the operator to hold the tripod in one hand and carry the data acquisition device in the other hand during the carrying process.

[0017] 2. By incorporating a lighting mechanism, this utility model allows the operator to simply turn on the lighting switch in low-light environments. The charging module then powers the lighting, providing a brighter environment for the data acquisition device. This avoids the need for the operator to spend more time and effort adjusting the equipment or searching for a light source. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a mobile large-space scanning three-dimensional data acquisition device.

[0027] like Figure 1-6 As shown, a mobile large-space scanning 3D data acquisition device includes a turntable 9 and a storage mechanism. The storage mechanism consists of a storage bucket 1, a first insertion rod 3, a second insertion rod 4, a third insertion rod 5, a fourth insertion post 6, and a pin 7. The bottom surface of the storage bucket 1 is fixedly connected to the first insertion rod 3. The first insertion rod 3 is inserted into the second insertion rod 4 through the pin 7. The second insertion rod 4 is inserted into the third insertion rod 5 through the insertion rod 3. The third insertion rod 5 is inserted into the fourth insertion post 6 through the insertion post 6. The turntable 9 is equipped with a lighting mechanism, which consists of a charging module 13 and a lighting lamp 12. The charging module 13 is electrically connected to the lighting lamp 12.

[0028] Please see Figure 1The top of the storage bucket 1 has multiple pin placement slots 100, and the bottom of the storage bucket 1 has three through slots 103. A sleeve 101 is rotatably connected to the outer circumference of the storage bucket 1, and a "U"-shaped rod 102 is fitted into the sleeve 101. The pin placement slots 100 are mainly used by the operator to place individual pins 7 into the pin placement slots 100. The sleeve 101 and the "U"-shaped rod 102 are consistent with the pull rod structure of suitcases on the market today, mainly to facilitate the operator to store the device as shown in the attached diagram of the instruction manual. Figure 2 When the device is in the indicated state, it is easy for the operator to pull out the device as set.

[0029] Please see Figure 5 There are three rods: rod 1 (3), rod 2 (4), rod 3 (5), and post 4 (6). All three rods 1 (3) are equipped with casters 2 at their bottoms. The three rods in the above structure are mainly triangular to provide stability, and are also based on the tripod design in existing technology.

[0030] Please see Figure 5 Each of the three insertion rods 3 has a through-hole 14. Insertion rods 4 and 5 each have a through-hole 14 at the top and bottom. Insert post 6 has multiple through-holes 60 at equal intervals. The insertion post 6 is marked with scale values. The multiple through-holes 60 are mainly designed to accommodate operators of different heights to raise the height of the data acquisition device 10. At the same time, the scale values ​​set on the insertion post 6 allow the operator to position the other two insertion posts 6 according to the scale values ​​displayed on the previous through-hole 60 after one through-hole 60 is locked by the pin 7. This is mainly to facilitate the operator to raise the height of the insertion post 6 in the pin 7.

[0031] Please see Figure 1 , Figures 3-6 The pin 7 is inserted into the insertion hole 14 of the insertion rod 3 and the insertion hole 14 at the bottom of the insertion rod 4. The insertion rod 4 passes through the through groove 103. The pin 7 is inserted into the insertion hole 14 at the top of the insertion rod 4 and the insertion hole 14 at the bottom of the insertion rod 3. The pin 7 is also inserted into the insertion hole 14 at the top of the insertion rod 3 and one of the insertion holes 14 of the insertion post 4. The method of using the pin 7 is as follows. Taking the insertion rod 3 and the insertion rod 4 as an example, first slide the insertion rod 2 4 up from the insertion rod 3 so that the insertion hole 14 of the insertion rod 3 and the insertion hole 14 at the bottom of the insertion rod 2 4 coincide. Then insert the pin 7 horizontally into the insertion hole 14 and the insertion hole 14 at the bottom of the insertion rod 2 4. Finally, lower the pin 7 so that the pin 7 hugs the insertion rod 3 and the insertion rod 2 4.

[0032] Please see Figure 1 The tops of the three inserts 6 are fixedly connected to the base 8, and the center of the base 8 is rotatably connected to the turntable 9; the turntable 9 can rotate on the base 8, so that the turntable 9 can rotate 360 ​​degrees horizontally, and at the same time drive the lighting mechanism to rotate synchronously.

[0033] Please see Figure 6 The turntable 9 has a charging module mounting slot 90, in which a charging module 13 is installed. A serpentine tube 11 is installed on the top of the turntable 9, and a light 12 is installed at one end of the serpentine tube 11. The wires of the charging module 13 and the light 12 are connected through the cavity inside the serpentine tube 11. The serpentine tube 11 can be bent and moved at will to adjust the position of the light 12 to fit the collection area of ​​the data acquisition device 10.

[0034] The implementation principle of the mobile large-space scanning three-dimensional data acquisition device in this application embodiment is as follows:

[0035] As shown in the attached diagram of the instruction manual. Figure 1 The contents are stored as shown in the attached diagram in the instruction manual. Figure 2 In the indicated state, the operation process is as follows:

[0036] Remove the pin 7 from the third pin 5, the second pin 4, and the first pin 3 in sequence, and place the turntable 9 into the pin placement slot 100 in sequence. At the same time, as the pin 7 is removed, the fourth pin 6 will retract into the third pin 5, the third pin 5 will retract into the second pin 4, and the second pin 4 will retract into the first pin 3. At this time, the base 8, the turntable 9, and the lighting mechanism will fall into the cavity of the storage bucket 1. At this time, the operator rotates the sleeve 101 to pull out the "U"-shaped rod 102 from the sleeve 101. The device can then be moved by pulling the "U"-shaped rod 102 in the retracted state via the universal wheels 2. By setting the tripod to retract the first pin 3, the second pin 4, the third pin 5, and the fourth pin 6 in sequence, the vertical length is avoided from being too long, which would be inconvenient for the operator to hold the tripod in one hand and carry the data acquisition device 10 in the other hand during the carrying process.

[0037] In low-light environments, the operator only needs to turn on the switch of the lighting lamp 12, and the charging module 13 will supply power to the lighting lamp 12. The lighting lamp 12 will then provide a brighter environment for the data acquisition device 10 to collect data, thus avoiding the inconvenience of the operator having to hold the lighting structure separately.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
