Abstract

The invention discloses a three-dimensional human body gait quantitative analysis system and method. The method comprises the following steps of: simultaneously using two inertia measurement nodes on feet, carrying out analyses fusion on the data of the two inertia measurement nodes, measuring a more accurate gait parameter, and obtaining information which can not be measured in a single-foot manner; and firstly storing the collected data in storage units of the measurement nodes in a walking process, and finally transmitting the collected data to an analytical calculation device in a wired or wireless manner after the walking process is ended. The high-speed acquisition of all gait information in the walking process can be realized and no characteristic gait information point is omitted. A foot part binding device of the designed inertia measurement node is adopted, a measuring error brought by fixed position shift of the measurement nodes in the walking process is eliminated, and the identity of fixed positions of the measurement nodes in a walking process is guaranteed through repeated measurement; and a gait analytical calculation program module adopts a moving window searching value method to definition a characteristic point of gait information, and can more exactly extract the gait diagnostic information.

Description

technical field [0001] The invention relates to the field of measurement analysis, in particular to a three-dimensional human body gait quantitative analysis system and method. Background technique [0002] Since the process of human walking is a very complicated process, and there are many important gait information in the process of walking, measuring and analyzing human gait information has many application prospects in real life, such as monitoring the rehabilitation of patients in clinical medicine degree, the control of bionic robots and other fields. At present, there are many methods for measuring and analyzing human gait: [0003] Traditional clinical measurements use stopwatches and meter sticks to obtain gait information using visual methods and footprint methods. This method mainly relies on manual records, so the errors caused by human factors are very large, and the obtained parameters have large errors, and it is difficult to accurately and quantitatively div...
