Abstract

The invention discloses a foot landing determination method and device based on a six-axis sensor. The foot landing determination method comprises the steps that movement data of an exerciser during the movement are collected, wherein the movement data are movement characteristic data and moments corresponding to the movement characteristic data detected by the six-axis sensor in the movement process of the exerciser; the moments corresponding to the movement characteristic data are subjected to characteristic point extraction, and predetermined characteristic points are obtained; movement characteristic data of a time interval where moments corresponding to the predetermined characteristic points are located are subjected to characteristic value extraction, so that characteristic vectorsof target movement data in the movement data are generated based on extracted characteristic values; and a foot landing mode of the exerciser is determined based on the characteristic vectors. According to the foot landing determination method and device based on the six-axis sensor, the technical problem that the reliability of a mode for detecting the foot landing mode of the exerciser in the correlation technology is low is solved.

Description

technical field [0001] The present invention relates to the technical field of foot landing recognition, in particular to a method and device for determining foot landing based on a six-axis sensor. Background technique [0002] The way the feet land on the ground when walking and running is very important for athletes. The wrong way of landing not only affects the performance, but also brings harm to the athletes. At present, the methods for detecting the way the athlete's feet land on the ground when walking or running are divided into human body gesture recognition based on vision and non-visual means. Among them, the human body gesture recognition method based on vision has relatively high cost, and has strict requirements on product structure design, and is not suitable for outdoor activities. For example, what is disclosed in the patent No. CN106730770A is the human body posture recognition based on visual means, which can be used for treadmills; the human body postur...
