Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of computer-aided equipment, in particular to a face recognition machine. Background Art
[0002] In the field of computer-aided devices, a face recognition machine is a device that uses face recognition technology to authenticate or identify a person by analyzing facial features. This device combines computer image processing technology with biometric principles to extract facial feature points and compare them, thereby achieving accurate and rapid identity authentication.
[0003] Face recognition machines are widely used in many fields. For example, in access control systems, face recognition machines can be used as entrance and exit control devices to ensure that only authorized personnel can enter specific areas. In attendance systems, face recognition machines can automatically record employee attendance, improving the efficiency and accuracy of attendance. In addition, face recognition machines are also used in finance, social security, communications, taxation, education, transportation, health and other fields, bringing convenience to people's lives and work.
[0004] Based on this, Chinese patent CN216211178U discloses a face recognition attendance machine, which includes a base. The base is a hollow structure. The four corners of the bottom of the base are fixedly connected to support columns. The bottom of the support column is fixedly connected to an anti-slip pad. The top of the base is clamped with a transparent protective cover. The interior of the base is provided with a fixing component for fixing the transparent protective cover. This face recognition attendance machine has the advantages of simple structure and easy use. In addition, the transparent protective cover can protect the face recognition attendance machine body, thereby preventing the face recognition attendance machine body from being damaged due to collision due to excessive personnel flow.
[0005] However, the above-disclosed facial recognition attendance machine still has technical problems of low facial recognition rate and insufficient convenience of use. Specifically, in the use of the facial recognition machine, the facial recognition machine can usually recognize changes in hairstyle, regular makeup, a certain degree of fat and thin changes, and aging. However, if a person's facial features change drastically, or there are interference factors such as lighting, exaggerated expressions, coverings, different postures, etc., the recognition accuracy may drop significantly. Therefore, in order to improve the recognition success rate of the facial recognition machine under different conditions, the user to be recognized needs to adapt to the recognition angle of the facial recognition machine by standing on tiptoe, changing the standing position, or changing the posture, in order to achieve an increase in the recognition rate.
