Embodiment Construction

[0019] In order to solve the following problems in the prior art: the applicable range and the detection range of the existing gait recognition method are small, the recognition effect is easily affected by the external environment, and the operation and maintenance cost of the equipment is relatively high. The first embodiment of the present invention provides a method for gait recognition, the flow chart of the method is as follows figure 1 As shown, including steps S101 to S106:

[0020] S101. Send a first acoustic signal according to a predetermined period by using an acoustic emission sensor.

[0021] In this embodiment, an acoustic signal is firstly sent to the pedestrian, which is referred to as the first acoustic signal in this embodiment. The signal should be a periodic signal, which may be a sinusoidal signal or other periodic signals.

[0022] S102. Receive a second acoustic signal by using an acoustic receiving sensor.

[0023] Specifically, in the embodiment of ...

Abstract

The present invention provides a gait recognition method and device. The gait recognition method comprises: transmitting a first acoustic signal according to a predetermined period by using an acoustic emission sensor; receiving a second acoustic signal by using an acoustic receiving sensor, wherein the second acoustic signal is an echo signal of the first acoustic signal; performing predeterminedprocessing on the second acoustic signal; acquiring a predetermined parameter of the second acoustic signal subjected to the predetermined processing; generating a feature vector from the predetermined parameter; and performing gait recognition on the feature vector by using a Bayesian classifier. In the method, the acoustic signals are processed, and influence of an external environment is less;since the acoustic signals is acquired by the acoustic sensor, the detection range of the method can be flexibly adjust, the cost is low, and the precision is high; and the method can solve the following problems in the prior art: the conventional gait recognition methods are small in application range and detection range, the recognition effect is affected by the external environment, and the operation and maintenance cost of the device is high.

Description

technical field [0001] The invention relates to the technical field of gait recognition, in particular to a method and device for gait recognition. Background technique [0002] In the face of constantly emerging security issues, commonly used biometric identification methods, such as fingerprint or face recognition, are no longer effective enough, which requires the introduction of new identification methods. Gait recognition is a newly emerging technology. The identification of people's identities is realized through the posture of walking people, which can effectively supplement the errors of fingerprint recognition, face recognition and other methods, and provide more reliable guarantee for social security. The current gait recognition methods mainly include methods based on computer vision, methods based on wearable devices, methods based on ground sensors, and methods based on radar, but the above-mentioned gait recognition methods have some shortcomings. For example,...
