Abstract

The invention provides a human body lower limb pose and gait detection device, and is used for detecting the pose and the gait of the lower limbs of the human body. The human body lower limb pose andgait detection device comprises a plurality of nine-axis motion sensors, a plurality of pressure sensors, a plurality of angle sensors and a main controller, wherein the nine-axis motion sensors are arranged at positions of rear waist, thighs on two sides, shanks and feet of the human body, and are used for detecting three-axis acceleration, three-axis angular velocity and three-axis geomagnetic field data; the pressure sensors are arranged on the pelma of the human body, and are used for detecting pressure data; the angle sensors are arranged at joints of the human body, and are used for detecting the joint bending angle data; and the main controller is arranged at the waist of the human body, and is connected with the nine-axis motion sensors, the pressure sensors and the angle sensors through a CAN bus. The invention further provides a gait detecting method adopting the human body lower limb pose and gait detection device. The gait detecting result is obtained through processing andanalyzing detection data of each sensor.

Description

technical field [0001] The invention belongs to the field of gait detection, and in particular relates to a device and method for detecting posture and gait of lower limbs of a human body. Background technique [0002] Human gait is a highly periodic and rhythmic movement process, and it has basic patterns that can provide a lot of information in a short period of time within a cycle. Gait analysis is to study the walking mechanism of the human body and obtain gait parameters through data analysis. Through the collection and quantitative analysis of gait information, the function of musculoskeletal and even nervous system can be evaluated. Before the advent of monitoring instruments, people mostly used visual indicators to understand what a normal gait should look like. But walking contains a wealth of information that is difficult to grasp intuitively, even for experienced observers. The gait analysis system based on measuring instruments can be used to quantitatively me...
