This utility model discloses a novel combined anti-counterfeiting label, comprising a label body. A transparent truncated cone is provided on the front end face of the label body. An anti-counterfeiting groove is provided within the transparent truncated cone. From the inside out, the anti-counterfeiting groove is provided with a color-changing anti-counterfeiting layer, a magnetic bead anti-counterfeiting layer, a fragile paper layer, a holographic pattern anti-counterfeiting layer, and a transparent waterproof layer. The transparent waterproof layer is sealed to the inner wall of the waterproof groove. The label body includes a base paper layer, a stainless steel positioning layer, a coated paper layer, a wear-resistant waterproof layer, and a stainless steel blade. The wear-resistant waterproof layer is integrally formed with the transparent truncated cone. The lower end of the stainless steel positioning layer is welded and fixed to the upper end of the stainless steel blade. The lower end of the stainless steel blade is provided with a cutting edge. The above technical solution has a reasonable structural design, multiple functions, good anti-counterfeiting performance, is easy to identify, and is practical.

The application provides a box recognition method, system and device based on multi-view vision and a storage medium, and the method comprises the following steps: obtaining a first image and a second image at different angles; inputting the first image and the second image into an image recognition neural network respectively to obtain local pattern information, corner point position, parallax information and 3D matching information representing a box; inputting the local pattern information and the corner point position into a context adjustment layer of a character detection neural network to obtain stereo information corresponding to the local pattern representing the box; and obtaining a spatial box with relative positions based on the corner point position and the stereo information. The application can enhance the algorithm recognition effect, has good real-time effect, consumes less computing resources, is convenient to deploy on a resource-limited vehicle-mounted edge device, is not prone to causing misrecognition and collision, and improves driving safety.

A user equipment (“UE”) in a wireless communication network can generate a padded identifier by inserting a string of padding bits in a field of an identifier associated with the UE. The UE can further encrypt the padded identifier to generate a hidden padded identifier. The UE can further transmit the hidden padded identifier to a network node operating in the wireless communication network.

This application provides a face image acquisition device and its control method, as well as a face image acquisition system. The device includes: a camera for acquiring a face image of a target person, the target person being the person whose face image is to be acquired; a first rotation mechanism for connecting the camera, the first rotation mechanism being used to drive the camera to rotate along a first direction, the first direction being parallel to a horizontal plane; and a second rotation mechanism for connecting the camera, the second rotation mechanism being used to drive the camera to rotate along a second direction, the second direction being parallel to a vertical plane. This solves the problem in the prior art where the positional offset of the acquired face image leads to difficulty in face recognition.

The invention discloses a display panel, a preparation method thereof and a display device. The display panel comprises a substrate and a pixel defining layer located on one side of the substrate, and a first opening is formed in the pixel defining layer; a light emitting device in the first opening; the packaging layer is located on one side, deviating from the substrate, of the pixel defining layer and the light-emitting device and is used for packaging the light-emitting device; the supporting layer and the black matrix are sequentially stacked on the side, away from the substrate, of the packaging layer, a third opening and a fourth opening are formed in the black matrix, the orthographic projection of the third opening on the substrate covers the orthographic projection of the first opening on the substrate, and the orthographic projection of the fourth opening on the substrate is not overlapped with the orthographic projection of the third opening on the substrate; the supporting layer is located in the fourth opening and makes contact with the peripheral side wall of the fourth opening. According to the display panel, the actual size of the fourth opening in the black matrix cannot be increased, and therefore it is guaranteed that the fourth opening area of the black matrix is not easily recognized by human eyes.
