[0002] Eyelash visual positioning is an application combining computer vision and image processing technologies. It is mainly used to accurately detect, track, or analyze the position, shape, and dynamics of eyelashes. It acquires eye images through high-definition cameras, microscopes, or professional eye imaging equipment. It needs to consider lighting conditions, angle, and resolution, remove noise such as skin texture interference, and enhance contrast to highlight the boundary between eyelashes and skin. Commonly used algorithms include Gaussian filtering and histogram equalization. Eyelash visual positioning devices can play an important role in many fields due to their high precision, automation, and user-friendliness.

[0003] In existing eyelash visual positioning devices, the positioning effect is generally not very good.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model embodiment provides an eyelash visual positioning device, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes a housing 1, an adjustment assembly 2 on the outer wall of the housing 1, and a positioning assembly 3 inside the housing 1. The positioning assembly 3 includes a motor 301, the output shaft of which is fixedly connected to a first bevel gear 302 via a coupling. A second bevel gear 303 is meshed with the outer wall of the first bevel gear 302. The motor 301 forms a rotating structure through the first bevel gear 302 and the second bevel gear 303. The outer diameter of the first bevel gear 302 matches the outer diameter of the second bevel gear 303, and the first bevel gear 302 and the second bevel gear 303 are arranged perpendicularly to each other, thus strengthening the first bevel gear 302. The connection between the first bevel gear 302 and the second bevel gear 303 allows the motor 301 to drive the first bevel gear 302, which in turn drives the second bevel gear 303 to rotate. A button 304 is rotatably connected to one end of the second bevel gear 303. A belt mechanism 306 is installed inside the second bevel gear 303, and a spring 305 is installed on one side of the belt mechanism 306. Two screws 307 are installed inside the belt mechanism 306, and the two screws 307 are symmetrically arranged about the horizontal centerline of the outer casing 1, which facilitates the placement of the screws 307 and allows them to be used for… For adjusting the position of the camera 309, a threaded sleeve 308 is threadedly connected to the outer wall of the screw 307. The camera 309 is fixedly connected to the top of the threaded sleeve 308. The camera 309 and the screw 307 form a threaded structure through the threaded sleeve 308, and the inner diameter of the threaded sleeve 308 matches the outer diameter of the screw 307. The inner wall of the threaded sleeve 308 fits snugly against the outer wall of the screw 307, enhancing the connection between the threaded sleeve 308 and the screw 307. This allows the screw 307 to rotate within the threaded sleeve 308, enabling the threaded sleeve 308 to drive the camera. Position adjustment is performed on 309. By starting motor 301, motor 301 drives the first bevel gear 302 to rotate. At this time, the first bevel gear 302 is disengaged from the second bevel gear 303. Screw 307 does not rotate. Button 304 needs to be pressed down to make the second bevel gear 303 mesh with the first bevel gear 302, which will drive the two screws 307 to rotate. This allows the screws 307 to rotate within the threaded sleeve 308, which in turn allows the threaded sleeve 308 to drive the camera 309 to adjust its position. This facilitates adjusting the position of the camera 309 without repeatedly starting and stopping motor 301.

[0022] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the adjustment component 2 includes a wearing ring 201. One end of the wearing ring 201 is fixedly connected to an elastic band 202, and the other end of the elastic band 202 is fixedly connected to a rubber pad 203. The wearing ring 201 and the rubber pad 203 form an integrated structure through the elastic band 202 and the rubber pad 203. The elastic band 202 is positioned between the wearing ring 201 and the rubber pad 203, which enhances the connection between the wearing ring 201 and the elastic band 202. This allows the wearing ring 201 to secure the rubber pad 203 with the support of the elastic band 202. An adjustment rod 204 is fixedly connected to one side of the outer casing 1. One end of the adjustment rod 204 is provided with a ball valve 205. A display screen 206 is provided on the outer wall of the ball valve 205. The adjustment rod 204 is connected to the ball valve. Adjustment rod 204 and display screen 206 form a movable structure, and ball valve 205 is located between adjustment rod 204 and display screen 206, enhancing the connection between adjustment rod 204 and ball valve 205. This allows display screen 206 to be angled via ball valve 205. Pulling rubber pad 203 allows it to be secured to the head by elastic band 202, facilitating use for people with different head shapes. Furthermore, after wearing, the length of display screen 206 can be adjusted via adjustment rod 204, and the display screen 206 can be tilted at different angles with the support of ball valve 205, meeting people's daily usage needs.

[0023] Working principle: During use, the rubber pad 203 can be pulled, allowing it to be securely fastened to the head under the action of the elastic band 202. This makes it easy for people with different head shapes to wear. Furthermore, after wearing, the display screen 206 can be adjusted in length by pulling the adjustment rod 204. Simultaneously, the display screen 206 can be adjusted to different tilt angles with the support of the ball valve 205, meeting people's daily usage needs. Additionally, starting the motor 301 allows the motor 3... 01 drives the first bevel gear 302 to rotate. At this time, the first bevel gear 302 is disengaged from the second bevel gear 303. The screw 307 does not rotate. The button 304 needs to be pressed down to make the second bevel gear 303 mesh with the first bevel gear 302, which will drive the two screws 307 to rotate. This allows the screws 307 to rotate within the threaded sleeve 308, which in turn allows the threaded sleeve 308 to adjust the position of the camera 309. This makes it easy to adjust the position of the camera 309 without repeatedly starting and stopping the motor 301.
