Description

Technical field [0001] The invention relates to the application field of sensors, in particular to a device based on a two-axis or three-axis acceleration sensor and a flexible sensor for identifying the movement posture of the lower limbs of the human body. Background technique [0002] The human body's lower limb motion posture capture is mainly based on two types of methods: a capture system based on video images and a capture system based on wearable sensors. [0003] The video image-based capturing system captures the human body motion picture through one or several video cameras, and determines the human body motion and the human body motion posture through a specially designed image processing algorithm. However, a video-based capture system usually can only perform video capture and recognition at the location where a specific camera is installed because the camera is installed in a fixed location. The human body is a moving object. When the subject leaves the detectable r...
