Description

Technical Field

[0001] This invention belongs to the field of handheld laser 3D scanning technology, specifically relating to a large-scene support for a handheld laser 3D scanner. When combined with a handheld laser 3D scanner, it enables large-scene scanning functionality for applications such as quality inspection, reverse engineering, and 3D printing. Background Technology

[0002] Handheld laser 3D scanners, as non-contact measurement systems, are widely used in high-end intelligent manufacturing. In 2015, my country released the "Made in China 2025" strategy, vigorously developing high-end intelligent manufacturing, which has become a crucial development strategy for many countries. Against this backdrop, handheld 3D scanning and inspection systems have emerged. Popular 3D scanning systems on the market are generally categorized into color white light handheld scanning systems, industrial-grade laser handheld scanning systems, optical tracking handheld scanning systems, and intelligent real-time industrial inspection systems. The highest precision is achieved by industrial-grade laser handheld scanning systems, reaching a minimum accuracy of 0.01mm. These systems can dynamically scan workpieces without affecting scanning accuracy, are highly adaptable, easily acquire data from bright surfaces, are simple to operate, and can easily and flexibly scan large workpieces. They are widely used in vehicle doors and windows, complex engine blocks and other vehicle components, as well as other industry parts. Features include high efficiency, flexible angles, and a large laser depth of field. They also have mesh hole filling and mesh post-processing optimization functions. However, to complete the scan, consumable markers must be applied to the workpiece to enable image recognition and accurate imaging during the scanning process. If the workpiece is large, applying and removing markers becomes a tedious process. The key issue in the research and design of this large-scene bracket is how to use fixed spatial surfaces to attach consumable markers to form standard positioning marks, thereby realizing large-scene scanning function. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The technical problem to be solved by this invention is: how to provide a large-scene support for handheld laser 3D scanners.

[0005] (II) Technical Solution

The large scene support is a semi-enclosed cubic box structure, including: a left panel 1, a right panel 5, a rear panel 3, a top panel 4, an adhesive strip 2, a reinforcing rib 6, and a turntable 7.

[0007] The left panel 1, right panel 5, and rear panel 3 are vertically arranged, and an upper panel 4 is attached above the left panel 1, right panel 5, and rear panel 3, thereby forming a semi-enclosed cubic box structure.

[0008] Each of the left panel 1, right panel 5, and rear panel 3 has an adhesive strip 2 on its bottom surface.

[0009] The turntable 7 is provided on the bottom surface of the interior space of the semi-enclosed cubic box structure; and the left panel 1 and the right panel 5 are connected at the lower front end by the reinforcing rib 6.

[0010] By attaching consumable markers to the left panel 1, right panel 5, rear panel 3, top panel 4, and turntable 7, a large-scene scanning environment can be created by combining it with a handheld 3D scanner and a target.

[0011] The manufacturing process of the left panel 1 is as follows: it is formed by welding angle aluminum and then riveting it to an aluminum plate.

[0012] The manufacturing process of the right panel 5 is as follows: it is formed by welding angle aluminum and then riveting it to an aluminum plate.

[0013] The manufacturing process of the rear panel 3 is as follows: it is formed by welding angle aluminum and then riveting it to an aluminum plate.

[0014] The manufacturing process of the upper panel 4 is as follows: it is formed by welding angle aluminum and then riveting it to an aluminum plate.

[0015] The contact portions of the left panel 1, right panel 5, rear panel 3, and top panel 4 are connected by fasteners.

[0016] The various panel components of the large scene support are made of aluminum alloy. Angle aluminum is welded together to form a frame, and then riveted to aluminum plates with blind rivets to form the left panel 1, right panel 5, rear panel 3 and top panel 4.

[0017] The left panel 1, right panel 5, rear panel 3 and top panel 4 are connected and fastened to each other by stainless steel hexagonal screws. Instant adhesive is used to fix the wear-resistant protective strip 2 at the positions where the left panel 1, right panel 5 and rear panel 3 contact the bottom surface. A reinforcing rib 6 is used to fix the left panel 1 and right panel 5 by stainless steel hexagonal screws.

[0018] A turntable 7 is added inside the semi-enclosed cube box structure. The turntable 7 consists of a support column, a turntable and weighing casters, thus forming a large scene support.

[0019] The large-scale support structure has an inner cavity with a side length of 2m and a volume of 8m³. 3 Each panel has a surface area of ​​4m². 2 There are 4 pieces in total, with a surface area of ​​16m². 2 The turntable has a diameter of 1m.

[0020] (III) Beneficial Effects

[0021] Compared with existing technologies, the large-scene support of this invention is suitable for handheld laser 3D scanners. Through optimized design and installation, it features high light transmittance, flexible and convenient loading and unloading, and easy mobility. Once the upper surface of each panel and turntable is covered with adhesive consumable markers, it can be used for a long time, thus reducing the usage rate of consumable markers, significantly lowering scanning costs, and improving scanning efficiency. When paired with a handheld laser 3D scanner, it enables large-scene scanning functionality.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, the large-scene support has been optimized in design. The simple and lightweight panel is easy to assemble and disassemble, and the components are placed on the turntable, which is easy to move quickly. Whether it is indoor or outdoor field inspection, a large-scene environment for handheld laser 3D scanning can be quickly set up, which can greatly improve the scanning and inspection efficiency.

[0024] Secondly, the uniform distribution of process holes on the panel surface can effectively increase light transmittance and the reflectivity of the markings on the panel, making them easier to collect.

[0025] Third, by using magnetic markers or attaching markers at intervals of 60-100mm on the panel surface to create a spatial marker scene environment, the number of disposable markers used for scanning parts will be greatly reduced, the auxiliary time will be shortened, efficiency will be improved, and costs will be effectively reduced.
