Abstract

The invention discloses a target gait posture evaluation method and device, equipment and a medium. The method comprises the steps of obtaining foot pressure data of a target object; feature points are selected, and specific behavior calibration is conducted on the foot pressure data; calculating a stride frequency according to the data at the feature points within a period of time, and determining the motion state of the target object through a preset stride frequency interval; performing static evaluation and dynamic evaluation on the target object; the static evaluation result and the dynamic evaluation result are coded respectively, and a static code and a dynamic code are obtained; inputting and encoding the posture data of the target object to obtain a posture code; according to the static codes, the dynamic codes and the posture codes, the correlation between the foot postures and the gaits and the postures is evaluated. According to the invention, the stress distribution of the planta pedis in daily activities is quickly and accurately captured in real time through a sensor technology, and the form and the force are identified and evaluated through a computer technology.

Description

technical field [0001] The invention belongs to the technical field of target posture assessment, and in particular relates to a target gait posture assessment method, device, equipment and medium. Background technique [0002] The feet and legs have an important status and influence on people's daily life. A healthy normal person will carry out a large number of activities involving the feet and legs every day, such as standing, walking, running and so on. Some wrong postures will not result in the need for medical attention in a short period of time (it will obviously affect life). However, keeping some wrong postures for a long time will affect the health of human bones and muscles in severe cases as the age increases, and in light cases will affect the posture, shape and appearance of the human body. Therefore, in order to ensure the correct exertion of force, it is necessary to identify the state of motion and discover the relationship between posture and posture. ...
