Embodiment Construction

[0036] As mentioned above, in the existing gait analysis technology, the collection equipment often needs to be installed and debugged in a preset area (usually indoor), which results in the collection of gait data can only be completed in this specific area. It is difficult to analyze the gait in people's daily life. In order to overcome the above shortcomings, the inventor introduced a combination of a wearable inertial sensor and an acoustic sensor (such as a microphone or an ultrasonic sensor) into the gait analysis technology, so as to realize the analysis of the gait in people's daily life. The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0037] According to an embodiment of the present invention, a method for constructing a gait data set based on a wearable acoustic sensor and an inertial sensor is provided. The data set constructed by this method integrates multi-modal data, and the obtained data set has a...

Abstract

The invention provides a method for establishing a gait data set. The method comprises steps as follows: 1) a test person walks along a straight line in a test area, and wearable sensors fixed on the left foot and the right foot of the test person acquire sensing data of a current walking process sample to serve as gait data of the sample; the wearable sensors comprise an inertial sensor and a sound sensor; 2) gait parameters of the current walking process sample are obtained by the aid of a camera preinstalled in the test area and/or footprints left in the test area; 3) gait data of the corresponding sample are marked by means of the gait parameters obtained in the step 2), and the marked gait data set is obtained. The invention further provides a corresponding gait analysis method based on the labeled data set. The accuracy of precise gait analysis is easily improved on the basis of the wearable sensors; multi-modal data are integrated, and the obtained data set is large in data volume, clear in classification and convenient to analyze and research.

Description

Technical field [0001] The present invention relates to the technical field of gait research and analysis. Specifically, the present invention relates to the technical field of gait data acquisition and measurement. Background technique [0002] The analysis and research of gait is a comprehensive study of human motor function, including the measurement, description and quantitative evaluation of human motion characteristics. Through the analysis and research of gait, the gait period can be identified, and the gait kinematics and dynamic parameters can be calculated. In recent years, gait research has played a very important role and application in sports training, disease diagnosis, rehabilitation and medical treatment, and identification. For example, in some sports training, gait analysis can be used to analyze some problems that athletes have during the training process, and then help them to get a commission; in disease diagnosis, gait analysis can be used to determine some...
