Description

Technical Field

[0001] The utility model belongs to the technical field of visitor management equipment, and specifically relates to an intelligent visitor management device based on face recognition. Background Art

[0002] The research on face recognition system began in the 1960s. After the 1980s, it was improved with the development of computer technology and optical imaging technology. It really entered the primary application stage in the late 1990s, and was mainly realized by technology from the United States, Germany and Japan. The key to the success of face recognition system lies in whether it has cutting-edge core algorithms and whether the recognition results have practical recognition rate and speed. "Face recognition system" integrates artificial intelligence, machine recognition, machine learning, model theory, expert system, video image processing and other professional technologies, and needs to be combined with the theory and implementation of intermediate value processing. It is the latest application of biometric recognition. The realization of its core technology shows the transformation from weak artificial intelligence to strong artificial intelligence.

[0003] At present, the existing face recognition visitor management device is generally equipped with a face recognizer for face recognition. Since the face recognizer lacks protection measures and is exposed to the external environment for a long time, the face recognizer is very easy to be damaged, which reduces the service life.
