[0039] Specifically, the parts of the first grabbing plate 325, the second grabbing plate 323, the first grabbing arc panel 335, the second grabbing arc panel 333, the upper push rod 345 and the lower push rod 343 that are in contact with the goods are provided with a protective layer, which can protect the goods and prevent damage caused by excessive force applied by the corresponding rotating motor and electric push rod.

[0040] Specifically, VR devices can adopt the following products: Oculus Quest 2, HTC Vive Cosmos, Pico 4, PS VR2, XREAL Air 2. Different products require different coordination. Some VR devices need to be connected to a smartphone or computer for experience, while others do not. For example, VR box: This device usually puts a smartphone in a special box and provides VR experience through the optical system inside the box. The price is cheap, but the experience is relatively limited. PCVR (head-mounted display): It needs to be connected to a computer via a data cable and uses the computer's high-performance graphics card for calculations to provide the most realistic virtual reality experience. VR all-in-one: It integrates all core modules such as processor, storage, and display, and can be used without connecting external devices.

[0041] Specifically: the image acquisition module 2 can use an existing optical 3D camera, which is an imaging device that can capture the three-dimensional information of an object and obtain the depth and shape of the object by optical means. This camera is usually composed of multiple cameras and depth sensors, which can realize the collection of three-dimensional information and convert these data into point clouds. In this embodiment, at least two optical 3D cameras are set, and the two optical 3D cameras are respectively located on both sides of the display cabinet 1. If better image acquisition is desired, optical 3D cameras can also be set at the top, bottom, etc. of the display cabinet 1, so that the image of the product can be more comprehensively collected.

[0042] Specifically, the image conversion module can use ReCap TM Software, 3DF Zephyr Aerial, Bitmap To Mesh v1.0.1, Retrovision and other software can be used to convert photos or pictures into 3D models.

[0043] Specifically, the display cabinet 1 can adopt an existing exhibition cabinet, which is mainly for placing the goods in the display cabinet 1 for image acquisition, and then converting the acquired image into a three-dimensional model, and finally converting it into a VR panoramic video, which is convenient for customers who browse offline with VR devices, and also convenient for online customers to browse through VR panoramic videos.

[0044] The method of converting images into VR panoramic videos is as follows:

[0045] Panoramic video technology: The production of VR panoramic videos requires projection transformation and splicing of images. Common projection methods include plane projection, cylindrical projection, spherical projection, and fisheye projection. These technologies can convert static images into dynamic panoramic videos, thereby providing an immersive experience in a virtual reality environment.

[0046] Dual fisheye panoramic video real-time stitching: This technology is mainly used to create a 360-degree full-view visual experience, which is common in virtual reality (VR) applications, panoramic photography and immersive media. By combining images taken with dual fisheye lenses, panoramic videos can be generated to further enhance the visual effects in virtual reality.

[0047] Application principle: the user first determines whether to use any one of the plane grabbing mechanism 32, the curved surface grabbing mechanism 33 and the irregular surface grabbing mechanism to clamp the product according to the product; for example, if the surface of the product is flat, first start the driving motor to drive the first screw 313 to rotate, and the first screw 313 rotates to make the first connecting seat 321 move along the axial direction of the first screw 313 until it moves to the middle of the display cabinet 1, and then the user supports the product on the second grabbing plate 323, starts the first electric push rod 324 to drive the first grabbing plate 325 to move downward, until the first grabbing plate 325 and the second grabbing plate 323 are aligned. The product is clamped stably, and then the image acquisition module 2 starts to capture images of the product's appearance. The first rotating motor 322 is started to drive the product to rotate, so that the image acquisition module 2 can more comprehensively capture the product's appearance image. The image acquisition module 2 then transmits the captured image to the image conversion module, and the image conversion module converts the image into a three-dimensional model. The three-dimensional model of the product can then be converted into a panoramic video for customers to watch, or it can be viewed by offline customers through VR equipment. This has a high protective significance for some high-value products, avoids damage to customers, and also facilitates customers to fully understand the products.

[0048] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
