[0002] Photogrammetry is a technique that extracts geometric information such as shape, size, and position from images of objects and performs 3D modeling or measurement. It combines photographic techniques, geometry, computer vision, and mathematical algorithms, and is widely used in surveying, geology, cultural heritage protection, engineering and architecture, industry and manufacturing, virtual reality, and other fields.

[0003] Photogrammetry techniques include aerial photogrammetry, close-range photogrammetry, digital photogrammetry, and motion-based structure reconstruction. In non-aerial photogrammetry, photogrammetric assemblies need to be fixed to the ground for mapping, especially when mapping building topography. During mapping, the photogrammetric equipment needs to be frequently moved, and traditional photogrammetric equipment requires manual labor to move it to the mapping location, often over long distances. Moving photogrammetric equipment is very labor-intensive and has poor portability. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See Figure 1 , Figure 2 This embodiment provides a photogrammetry combination device, including: device body 1, lifting mechanism 2 and pulling mechanism 3.

[0033] The main body 1 of the device can be designed as a cuboid or a cylinder. The main body 1 of the device has a receiving through hole 101, which can also be designed as a cuboid or a cylinder. The receiving through hole 101 is used to accommodate photogrammetric equipment.

[0034] The lifting mechanism 2 includes a lifting block 21, a lifting rod 22, and a linkage plate 23. The lifting block 21 is located within the accommodating through hole 101 of the main body 1 to support the photogrammetric equipment, and the cross-section of the lifting block 21 matches the cross-section of the accommodating through hole 101 of the main body 1. One end of the lifting rod 22 is connected to the lifting block 21, and the lifting rod 22 and the lifting block 21 can be detachably designed with threaded connection, snap-fit ​​connection, etc. (See also...) Figure 6 The other end of the lifting rod 22 is provided with a first thread 2201. The linkage plate 23 is connected to the main body 1 of the device and is supported by the main body 1. The linkage plate 23 is provided with a second thread 2301 inside. The first thread 2201 and the second thread 2301 cooperate to enable the lifting rod 22 to rise and fall relative to the linkage plate 23. The first thread 2201 and the second thread 2301 can be designed as external threads or internal threads, as long as the first thread 2201 can cooperate with the second thread 2301. When the lifting rod 22 is lowered a certain distance, the accommodating through hole 101 is in a state that can accommodate the photogrammetric equipment, which is convenient for storing the photogrammetric equipment.

[0035] The lifting mechanism 3 is connected to the main body 1 of the device and allows the user to lift to save effort.

[0036] The working principle of the photogrammetric combination device of this utility model is as follows:

[0037] When preparing to install the photogrammetric equipment, twist the lifting rod 22 to lower the lifting block 21 so that the receiving through hole 101 is in a state that can accommodate the photogrammetric equipment. The depth to which the lifting block 21 descends in the receiving through hole 101 is determined according to the required installation depth of the photogrammetric equipment. After the first round of photography is completed, if it is necessary to move the photogrammetric equipment a long distance to photograph the next photography point, there is no need to remove the photogrammetric equipment from the receiving through hole 101. Instead, simply lift the lifting mechanism 3 to suspend the main body 1 of the device. This saves effort and improves portability during long-distance movement of the photogrammetric equipment. After arriving at the next photography point, lower the lifting mechanism 3, and the photogrammetric equipment can be used directly for photography without readjusting the height of the lifting block 21, i.e., without reinstalling the photogrammetric equipment into the receiving through hole 101.

[0038] Obviously, since the lifting block 21 rises and falls with the lifting rod 22, the height of the lifting block 21 within the receiving through hole 101 can be adjusted according to the shooting height of the photogrammetric equipment or the size of different photogrammetric equipment, making the photogrammetric assembly device adaptable to more models of photogrammetric equipment. The lifting mechanism 3 facilitates the user's movement of the photogrammetric assembly device, improving the convenience of moving the photogrammetric equipment. That is, after changing the shooting point midway, there is no need to take the photogrammetric equipment out of the receiving through hole 101 and put it back, improving shooting efficiency. When the lifting block 21 reaches the top of the device body 1, the photogrammetric assembly device can be used as a simple shooting stand for the photogrammetric equipment to take pictures. Thus, the photogrammetric assembly device of this utility model can facilitate the movement of photogrammetric equipment and can also be used as a simple shooting stand for taking pictures, realizing the dual function of movement and shooting, improving the practicality and convenience of the photogrammetric assembly device.

[0039] Multiple support rods 4 are hinged to the outside of the main body 1 of the device. A linkage rod 5 is hinged between the support rods 4 and the linkage plate 23, supporting the linkage plate 23. When the support rods 4 swing relative to the main body 1, the linkage rod 5 swings relative to the linkage plate 23. Based on the above connection, there are at least two support rods 4. When the support rods 4 are extended outwards, they can be mounted on the bottom surface. In conjunction with the lifting mechanism 2, the photogrammetric equipment can be raised and its position adjusted. At this time, the photogrammetric assembly can function as a simple camera stand. Before the support rods 4 retract inwards, the rod body of the support rods 4 is retracted, allowing the support rods 4 to be in a retracted state relative to the entire photogrammetric assembly, thus reducing the space required to carry the photogrammetric assembly.

[0040] The lifting mechanism 2 also includes a first knob 24, which is connected to the bottom of the lifting rod 22. The first knob 24 and the lifting rod 22 are integrally formed together. The first knob 24 and the lifting rod 22 can also be detachable. However, based on the threaded connection between the lifting rod 22 and the linkage plate 23, the connection between the first knob 24 and the lifting rod 22 is not suitable for threaded connection. In addition, the first knob 24 can also be a more labor-saving crank-type design.

[0041] See Figure 3 The inner wall of the accommodating through hole 101 of the main body 1 of the device is provided with a limiting part 13. The limiting part 13 protrudes from the outside to the inside along the radial direction of the accommodating through hole 101. The limiting part 13 is used to prevent the lifting block 21 from disengaging from the accommodating through hole 101, that is, the lifting block 21 is restricted to move within the accommodating through hole 101. When the lifting rod 22 is twisted, the twisting distance is the moving distance of the lifting block 21, which prevents unnecessary twisting of the lifting rod 22 and saves twisting force.

[0042] A cover 6 is hinged to the outside of the main body 1, and the cover 6 is used to seal the top of the receiving through hole 101. A cover buckle 7 is provided on the outside of the main body 1, and the cover 6 is engaged with the cover buckle 7 to reduce the damage to the photogrammetric equipment caused by rainwater or sand entering the receiving through hole 101 of the main body 1 in rainy or dusty weather. The cover 6 can also be connected to the main body 1 by plugging or threading to seal the receiving through hole 101.

[0043] The support rod 4 is a telescopic structure. A second knob 8 is provided at the hinge point between the support rod 4 and the linkage rod 5. The second knob 8 is used to adjust the swing angle of the support rod 4 relative to the main body 1 of the device. When it is necessary to move the photogrammetric equipment, retract the support rod 4 and then tighten the second knob 8 to prevent the support rod 4 from shaking. When it is necessary to take pictures, first loosen the second knob 8, then extend the support rod 4, adjust the support rod 4 to a suitable state, and then tighten the second knob 8 to prevent the support rod 4 from shaking and affecting the picture quality.

[0044] See Figure 4 The support rod 4 also includes a foot 9, which is used to fix the ground to stabilize the photogrammetry assembly. The foot 9 is threaded to the bottom of the support rod 4 for easy disassembly and replacement. The foot 9 can be a tapered foot 9 or a claw-shaped foot 9, etc.

[0045] See Figure 5The main body 1 of the device is connected to a support structure, and the support structure is threadedly connected to a pulley seat 10. The pulley seat 10 is connected to a pulley 11, and the pulley seat 10 is adapted to be threadedly connected to the bottom of the support rod 4. The number of pulley seats 10 and pulleys 11 corresponds to the number of legs 9. When it is necessary to move the photogrammetric equipment, the legs 9 installed on the support rod 4 can be removed and replaced with pulley seats 10 connected to pulleys 11. The removed legs 9 can be installed on the support structure of the main body 1 for easy management. After adjusting the support rod 4, the photogrammetric equipment can be moved by means of the lifting mechanism 3 and the pulleys 11, which is more labor-saving than simply carrying it by hand.

[0046] The lifting mechanism 3 includes two pull rods 31 and a crossbar 32. The pull rods 31 are hinged to the main body 1 of the device, and each end of the crossbar 32 is connected to one of the pull rods 31. When it is necessary to move the photogrammetric equipment, the crossbar 32 can be held and pulled upwards; when it is necessary to take pictures, the pull rods 31 can be swung to prevent them from interfering with the photogrammetric equipment. The pull rods 31 can also be designed as a chain formed by steel rings instead of the hinge.

[0047] One end of the lifting block 21 is connected to a turntable 12, which is used to support the photogrammetric equipment to enable the photogrammetric equipment to rotate and take pictures. The turntable 12 can also be detachably connected to the photogrammetric equipment to improve the picture quality, and the turntable 12 can also be detachably designed from the lifting block 21.
