Human body identity recognition system

Abstract

The invention discloses a human body identity recognition system which comprises a pressure measurement device, a signal conditioning circuit, an analog / digital (A / D) converter, a microprocessor, a wireless transmission module, a wireless receiving module and an upper computer which are electrically connected in sequence. The system is characterized in that the pressure measurement device is a sock-type foot pressure measurement device which mainly comprises a sensor array mainly composed of 19 miniature pressure sensors; the miniature pressure sensor array is placed at the bottom of the sock-type foot pressure measurement device, and is distributed according to corresponding positions as follows: the first toe to the fifth toe are respectively provided with one miniature pressure sensor;the far ends of first, second, third, fourth and fifth metatarsal bones are respectively provided with miniature pressure sensor; the near ends of first, second, third, fourth and fifth metatarsal bones are respectively provided with one miniature pressure sensor; cuneiform bone, the middle part of navicular bone and the tail end of the navicular bone are respectively provided with one miniature pressure sensor; and four miniature pressure sensors are distributed at calcaneus.

Description

technical field [0001] The invention relates to safety technology, in particular to a human body identification system, which is based on human foot pressure. Background technique [0002] Accurately identifying people's identities is an important task in the field of security technology. With the development of society, many departments have the task of human identification. Since identification not only involves individuals and enterprises, but also relates to national information security, there is an urgent need for a fast, accurate and convenient human identification method. Traditional human identification methods include certificates and passwords. But certificates are easy to be counterfeited and lost; passwords are easy to be cracked and forgotten. The current identification method is gradually being replaced by biometric technology. Biometric technology is a new technology for automatic identification based on the physiological or behavioral characteristics of ...

Problems solved by technology

Most of the existing gait identification technologies are aimed at the realization of the recognition algorithm. Technically, the image sequence is generally obtained through the camera, and then the image is processed, and then the method of extracting features for identification cannot break through the limitations that restrict its practical application. bottleneck
