Abstract

The present invention relates to the field of human motion recognition, and provides a human motion recognition method based on multi-sensor data fusion, which includes: using N inertial sensor nodes respectively fixed on different parts of the human body to collect human motion data; using sliding window segmentation technology for each The human body action data collected by each sensor node is divided into windows to obtain multiple action data segments of each sensor node; the feature extraction is performed on the action data segments of each sensor node to obtain the corresponding feature vector; the RLDA algorithm is used to obtain the obtained The feature vector of each sensor node is subjected to feature dimensionality reduction; the feature vector after dimensionality reduction of each sensor node is used as training data for parameter training and modeling, and the corresponding layered fusion model is obtained; using the obtained layered fusion model, the Human action recognition. The invention can effectively overcome the drawbacks of the single classifier in the recognition process, and can effectively improve the recognition accuracy of human body actions.

Description

technical field

[0001] The invention relates to the field of human motion recognition, in particular to a human motion recognition method based on multi-sensor data fusion. Background technique

[0002] Human action recognition technology is a new human-computer interaction method that has emerged in recent decades, and it has gradually become a hot issue studied by scholars at home and abroad. Human body movements mainly refer to the way the human body moves, as well as people's responses to the environment or objects. The human body describes or expresses complex human movements through complex movements of the limbs. It can be said that most of the actions of the human body need to be reflected through the movement of the body limbs. It becomes a very effective way to analyze the human body's motion by studying and exploring the human body's motion. Human action recognition based on inertial sensors is an emerging research field in the field of pattern recognition. Its ...
