Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a link, or a specific 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 connection within two groups. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, this utility model proposes a handheld 3D scanning device, which includes a handle 100, a lidar device 200, a bracket 300, an imager 400, and a fill light 500. The lidar device 200 is detachably mounted on the handle 100. The first end of the bracket 300 is mounted on the lidar device 200, and the second end of the bracket 300 extends above the lidar device 200. The second end of the bracket 300 is provided with a bracket 301 and a slot 302. The imager 400 is mounted in the bracket 301, and the fill light 500 is snapped into the slot 302.

[0029] Specifically, the handle 100 is designed to conform to the structure of the human hand. In this embodiment, the handle 100 can serve as a power supply device, containing a built-in battery. The handle 100 also has a charging port, a power supply port, and a corresponding power switch. (See attached...) Figure 3As shown, the handle 100 has a detachable structure, which includes, but is not limited to, a locking structure, a fastener structure, a pin structure, and a screw engagement structure. A power supply module is located next to the detachable structure. The LiDAR device 200 has a corresponding structure that engages with the detachable structure and the power supply module. The power supply module is electrically connected to the battery to supply power to the LiDAR device 200. The LiDAR device 200 is used to quickly and accurately measure the three-dimensional structure of the scene and generate a high-precision three-dimensional point cloud. The handheld three-dimensional scanning device also has a built-in inertial measurement unit and an integrated computing platform. The inertial measurement unit is used for real-time attitude tracking and navigation to ensure the stability and accuracy of the device during the scanning process. The integrated computing platform is used to process sensor data in real time, execute three-dimensional modeling and photo registration algorithms, generate high-quality three-dimensional point clouds and panoramic photos, and automatically register the positions on the terminal to realize the real-world three-dimensional presentation.

[0030] Furthermore, multiple slots 302 are provided and are evenly arranged along the length of the bracket 300. The fill light 500 is provided with multiple hooks 501, which are used to engage with the slots 302. By engaging the multiple hooks 501 with the slots 302 respectively, the fill light 500 is installed on the bracket 300.

[0031] As attached Figure 2 As shown, the hook 501 is an L-shaped component facing downwards, while the slot 302 is not just a slot, but an L-shaped slot that adapts to the hook 501. When the fill light 500 is close to the bracket 300, the hook 501 on it is correspondingly embedded in the slot 302 and installed downwards, so that the L-shaped structure of the hook 501 is adapted to the L-shaped slot of the slot 302, thereby realizing the installation of the fill light 500 on the bracket 300. Of course, in another embodiment, the connection structure for the fill light 500 to be installed on the bracket 300 includes, but is not limited to, the assembly relationship between the hook 501 and the slot 302. It can also adopt a magnetic structure, a buckle structure, a Velcro connection structure, or even a rope structure such as a cable tie for direct winding connection.

[0032] Furthermore, the camera 400 includes a panoramic camera, and the fill light 500 has multiple fill lights 502 on both opposite sides.

[0033] Specifically, since there are some dark corners in the shooting scene, the details in these dark areas are not clear. Therefore, multiple fill lights 502 are used for supplementary lighting. Since the panoramic camera used in this embodiment of the camera 400 has two lenses, which are placed on two opposite sides of the camera body, the multiple fill lights 502 are correspondingly set on the two opposite sides of the fill light unit 500. The two opposite sides of the fill light unit 500 face the two opposite sides of the camera body, so that the panoramic camera can obtain a better lighting environment, improve shooting quality and provide high-definition visual information.

[0034] Furthermore, the handheld 3D scanning device also includes a fixing member 600. The tray 301 is provided with a first hole 3011, and the imager 400 is provided with a second hole 401 corresponding to the first hole 3011. When the imager 400 is installed in the tray 301, the first hole 3011 and the second hole 401 are coaxial, and the fixing member 600 passes through the first hole 3011 and the second hole 401 in sequence to fix the imager 400 in the tray 301.

[0035] The second hole 401 includes an internally threaded hole, and the fastener 600 includes a screw that mates with the internally threaded hole.

[0036] Side wing plates 3012 are provided on both sides of the bracket 301.

[0037] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
