Abstract

The embodiment of the invention relates to the technical field of gait identification and discloses a freezing gait identification method and device and a gait detector. The method includes the stepsof receiving gait information; according to the gait information, determining kinetic parameters of lower limbs; judging whether or not the kinetic parameters of the lower limbs satisfy any one of a first preset condition, a second preset condition and a third preset condition, wherein the first preset condition is used for distinguishing freezing gaits in a static state, the second preset condition is used for distinguishing freezing gaits in a high-frequency state, and the third preset condition is used for distinguishing freezing gaits in other states except the static state and the high-frequency state; when the kinetic parameters of the lower limbs satisfy any one of the first preset condition, the second preset condition and the third preset condition, determining that the gaits arefreezing gaits. By means of the freezing gait identification method, erroneous judgement can be effectively reduced, and the accuracy of the judgment on the freezing gaits is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of gait recognition, in particular to a frozen gait recognition method and device and a gait detector. Background technique [0002] Walking, that is, walking on foot, is a complex movement of human body displacement mainly through the lower limbs. Walking is one of the basic activities of human beings. Human gait refers to all movements, postures and behavioral characteristics in the process of human walking. Human gait recognition is of great significance to various fields, such as sports, biometrics, rehabilitation, and health diagnosis. For example, in terms of health diagnosis, gait recognition can determine whether there is a disease and distinguish the symptoms of patients. Among them, for many diseases, such as Parkinson's disease (Parkinson's disease, hereinafter referred to as PD), etc., it will cause abnormal gait of patients. Freezing, difficulty starting, etc. Abnormal ...
