Description

Technical Field

[0001] This utility model relates to the field of pearl identification technology, specifically to a high-resolution camera based on automatic pearl identification. Background Technology

[0002] For a long time, consumers have been unable to distinguish between saltwater and freshwater pearls. Some merchants sell inexpensive freshwater pearls as expensive saltwater pearls, and the trading volume and value of saltwater pearls rank among the top in the country. Beihai's pearl industry has gradually transitioned from a traditional, single-product production model to an integrated industry encompassing cultivation and processing. Beihai pearls once enjoyed great success, but in recent years, the situation facing Beihai's South Sea pearl industry has become increasingly severe. This is mainly reflected in the frequent occurrence of freshwater pearls being passed off as saltwater pearls, severely damaging the reputation of South Sea pearls, leading to a sharp decline in South Sea pearl cultivation, and impacting the development space of South Sea pearls.

[0003] Existing identification devices on the market generally use cameras and AI recognition systems to capture and identify pearls in the shooting area. After identifying the pearls, they distinguish between saltwater and freshwater pearls by the different textures on the pearl's surface. However, in actual use, there are strict requirements for the lighting at the observation position in order to distinguish the textures on the pearl's surface. If the lighting conditions cannot be adjusted to a certain extent as needed, it may affect the recognition efficiency of the device. Therefore, we propose a high-resolution camera based on automatic pearl recognition. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-resolution camera for automatic pearl recognition. This solves the problem that, in practical use, strict requirements are placed on the lighting at the observation position in order to distinguish the textures on the surface of pearls. If the lighting conditions cannot be adjusted to a certain extent as needed, the recognition efficiency of the device may be affected.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A high-resolution camera based on automatic pearl recognition includes a fixed housing. A first fixed plate is fixedly installed on the bottom surface of the fixed housing. A fixed hole is opened on the top surface of the first fixed plate. A second fixed plate is fixedly installed inside the fixed hole. Two first light-transmitting holes are opened on the top surface of the second fixed plate. A rotating hole is opened on the top surface of the second fixed plate. A rotating tube is sleeved inside the rotating hole. Two first light-shielding plates are fixedly installed on the outer wall of the rotating tube. A rotating shaft is sleeved inside the rotating tube. Two second light-shielding plates are fixedly installed on the outer wall of the rotating shaft. A second light-transmitting hole is opened on the top surface of the second light-shielding plate.

[0007] Preferably, the outer wall of the fixed shell is provided with a sliding hole, a contact plate is provided inside the sliding hole, and a sliding plate is fixedly installed on the inner wall of the contact plate. The contact plate is engaged with the sliding hole through the sliding plate.

[0008] Preferably, a carrying tray is fixedly installed on the top surface of the tray, and a plurality of carrying slots are formed on the top surface of the carrying tray. The plurality of carrying slots are evenly distributed on the top surface of the carrying tray according to a circular trajectory, and the circular trajectory formed by the plurality of carrying slots is the same as the center of the carrying tray.

[0009] Preferably, the top surface of the tray has a first through hole, and the top surface of the cargo tray has a second through hole. The first through hole and the second through hole are aligned. A viewing block is fixedly installed inside the first through hole. The viewing block is made of glass.

[0010] Preferably, the top surface of the fixed shell is provided with a third through hole, and a connecting shaft is sleeved inside the third through hole.

[0011] Preferably, a connecting plate is fixedly installed on the outer wall of the connecting shaft. The connecting plate has an L-shaped structure, and a camera body is fixedly installed on one side of the vertical portion of the connecting plate. The camera body is a high-resolution camera, and the camera body is electrically connected to the central processing unit.

[0012] In summary, the present invention has the following main advantages:

[0013] 1. By setting the first fixed plate, it needs to be placed above the fill light during use. It is fixed to the fixed position by the fixing device. Through the design of the rotating tube and rotating shaft, the sleeve design can adjust the position and relative position of the first light shield and the second light shield. When the second light shield blocks the first light-transmitting hole and the first light shield blocks the second light-transmitting hole, the internal environment is in a weak lighting condition. When the second light shield blocks the first light-transmitting hole but the first light shield and the second light-transmitting hole are offset, the internal environment is in a normal lighting environment. When the first light-transmitting hole and the second light-transmitting hole are unobstructed, it can be in a bright environment. The user can turn the part of the rotating tube and rotating shaft located outside the fixed shell as needed to adjust the position of the second light shield and the first light shield to ensure the camera's efficient recognition.

[0014] 2. By setting up a contact plate, the design of the contact plate and the slide plate allows the staff to easily pull it out at any time to put the test piece into the device, providing convenience for the use of the device. The design of the loading slot can limit the load on the pearl to be tested, preventing it from shifting after being subjected to slight external force inside, which would affect the camera's capture and recognition, and ensure the efficient operation of the device. The design of the transparent block ensures that light can enter the device normally without damaging the internal sealed environment, ensuring that the light adjustment component can function properly.
