Description

Technical Field

[0001] The utility model relates to the technical field of high-precision surveying and mapping, in particular to a portable installation device for a spherical target that can be telescoped and rotated. Background Art

[0002] In modern surveying and mapping and 3D scanning technologies, spherical targets, as important reference tools, are mainly used in the process of collecting and processing point cloud data. Through spherical targets, surveyors can align data at different scanning positions, calibrate the accuracy of scanners, and ensure the consistency of point cloud data. This is crucial for application scenarios such as high-precision 3D modeling, topographic surveying, and building measurement.

[0003] In practical applications, after a series of scans and shootings of spherical targets, a large amount of point cloud data is generated. Before these point cloud data are integrated, it is necessary to ensure that the position and attitude of each spherical target are accurate. Therefore, the spherical surface of the spherical target not only needs to have high reflectivity and high precision, but also needs to ensure the stability of the target when placed. This requires that the connection support structure between the spherical target and the measured point must have a certain stiffness and stability to ensure the visibility and stability of the spherical target in various complex environments.

[0004] In the prior art, the installation devices of spherical targets mainly have the following technical problems: 1. At present, the installation devices of spherical targets often adopt the form of tripods, which are difficult to be stably placed on some complex terrains, have a large footprint, and are easily blocked by surrounding obstacles, affecting the visibility of spherical targets. 2. Common spherical target installation devices are usually fixed brackets, which cannot freely adjust the angle and position of the spherical target, and the carrying and installation processes are complex, greatly affecting the work efficiency and being difficult to meet the application requirements of various work scenarios. 3. Spherical targets are often used as known reference points, and their installation devices need to ensure the repeatability of the spherical target positions, so as to provide consistent reference data in multiple measurements. Therefore, the installation devices of spherical targets need to have a certain stiffness to ensure that the spherical targets do not move during the measurement process.

[0036] As Figures 1-5 shown, the present utility model provides a portable installation device for a retractable and rotatable spherical target. Some specific embodiments are described below. One of the portable installation devices for a retractable and rotatable spherical target includes a base for fixing on the surface of a structure, a first telescopic device 1 connected to the base, a second telescopic device 2 connected to the first telescopic device 1, and a spherical target 5 connected to the other end of the second telescopic device 2.

[0037] More specifically, the first telescopic device 1 is a multi-stage rotatable telescopic device. In this embodiment, the first telescopic device 1 is a three-stage rotatable telescopic device. The first telescopic device 1 includes a first large sleeve 12, a first middle sleeve 13, and a first small sleeve 14 that are sleeved in sequence. The first middle sleeve 13 can move and rotate within the first large sleeve 12, and the first small sleeve 14 can move and rotate within the first middle sleeve 13. The sequential sleeving of the first large sleeve 12, the first middle sleeve 13, and the first small sleeve 14 to achieve rotation and telescoping is prior art and will not be elaborated here. An external threaded connector 15 is formed at the end of the first large sleeve 12 for connection to the base to make the connection more stable. A first connecting block 11 is welded to the free end of the first connecting block 11, and a hinge hole is formed in the first connecting block 11 for hinging with the second telescopic device 2.

[0038] The second telescopic device 2 is a multi-stage rotatable telescopic device. In this embodiment, the second telescopic device 2 is a three-stage rotatable telescopic device. The second telescopic device 2 includes a second large sleeve 22, a second middle sleeve 23, and a second small sleeve 24 that are sleeved in sequence. The second middle sleeve 23 can move and rotate within the second large sleeve 22, and the second small sleeve 24 can move and rotate within the second middle sleeve 23. The sequential sleeving of the second large sleeve 22, the second middle sleeve 23, and the second small sleeve 24 to achieve rotation and telescoping is prior art and will not be elaborated here. A second connecting block 21 is welded to the side of the end of the first small sleeve 14, and a hinge hole is also formed in the second connecting block 21. By passing a bolt through the hinge hole of the second connecting block 21 and cooperating with a nut for connection, the hinging of the second connecting block 21 and the first connecting block 11 is achieved, enabling the first telescopic device 1 and the second telescopic device 2 to adjust the angle and be fixed. Loosen the bolt connection for adjustment and then tighten the bolt connection for fixation, facilitating the precise adjustment of the position of the spherical target 5. A groove 25 is formed at the end of the second large sleeve 22, and the groove 25 has magnetism. A disc 7 is fixed to the spherical target 5 through a connecting rod 6. The material of the disc 7 is made of iron, and the disc 7 can be inserted into the groove 25 and adsorbed to achieve the fixation of the spherical target 5.

[0039] Both the first telescopic device 1 and the second telescopic device 2 utilize a three-section free telescopic design made of high-strength stainless steel, with high stiffness, not easily deformed, and can freely adjust the lengths of the first telescopic device 1 and the second telescopic device 2 according to usage requirements.

[0040] Such as Figure 1In the specific embodiment shown, the first telescopic device 1 is horizontally arranged, and the second telescopic device 2 is vertically arranged. In order to fix the base more firmly at different positions and be able to flexibly replace the base according to the usage scenario and select different installation methods, the base adopts a magnetic adsorption base 3 or an anchoring base 4. When the fixed position is on the surface of a ferromagnetic material, the magnetic adsorption base 3 is used. The magnetic adsorption base 3 includes a first internal thread interface 31 and a magnetic adsorption main body 32 that are connected to each other. The electromagnetic coil module, power supply module, and retaining plate module are all integrated inside the disc-shaped magnetic adsorption main body 32. How to generate magnetism specifically is the prior art and will not be elaborated here. The first internal thread interface 31 is fixedly connected to the outside of the magnetic adsorption main body 32 and is connected to the external thread connector 15 of the first telescopic device 1 by means of threads. When the magnetic adsorption main body 32 is powered on, the bottom of the magnetic adsorption main body 32 can be made magnetic, so as to firmly adsorb the entire retractable and rotatable spherical target portable installation device on the surface of the ferromagnetic material. When the fixed position is a non-ferromagnetic material (such as a concrete material), the anchoring base 4 is used. The anchoring base 4 includes a second internal thread interface 41 and an anchoring main body 42 that are connected to each other. Four connection holes 43 are provided on the anchoring main body 42 and are evenly distributed along the circumferential direction. The second internal thread interface 41 is connected to the external thread connector 15 of the first telescopic device 1 by means of threads. By passing bolts through the connection holes 43 and embedding them inside the non-ferromagnetic material (such as a concrete material), the retractable and rotatable spherical target portable installation device is firmly installed on the surface of the structure.
