Description

Technical Field

[0001] This utility model relates to the field of palm vein recognition technology, and specifically to a palm vein recognition device. Background Technology

[0002] Palm vein recognition is a biometric technology based on the distribution pattern of veins in the human palm, belonging to the category of in vivo feature recognition. It captures a unique image of the subcutaneous vein network by illuminating the palm with near-infrared light (approximately 760nm wavelength) and utilizing the absorption characteristics of infrared light by hemoglobin in the blood. The algorithm then extracts features for identity verification.

[0003] Chinese patent application number 202420248637.1 discloses a meeting registration device based on palm vein recognition, including a device base. A top cover is fixedly connected to the top of the device base. A near-infrared CCD camera is installed at the middle position of one side of the front end of the top cover. An operation guidance mechanism is provided at the front end of the top cover. This meeting registration device based on palm vein recognition, by incorporating a speaker, an LCD screen, and an infrared distance sensor, allows the near-infrared CCD camera to capture the user's palm vein characteristics during use. The infrared distance sensor senses the distance between the user's palm and the near-infrared CCD camera and displays an image of the palm on the LCD screen. Based on the distance of the palm, an audio prompt is played through the speaker to remind the user to bring their palm closer or further away, increasing the convenience of operation and realizing the operation guidance function, thus solving the problem of devices lacking operation guidance functionality.

[0004] Paragraph 0032 states: "During the recognition process, the infrared ranging sensor 5 senses the distance between the user's palm and the near-infrared CCD camera 6, and displays an image of the palm on the LCD screen 4. Depending on the distance of the palm, the speaker 3 plays an audio reminder to bring the palm closer or further away, increasing the convenience of operation." The entire recognition process is particularly troublesome. First, ordinary people are not accurate in controlling distance. Even if the speaker plays an audio reminder to bring the palm closer or further away, the user cannot control it well. Moreover, after multiple unsuccessful recognitions, the user is prone to frustration.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content
