Description

technical field

[0001] The present invention relates to the computing field, in particular to a feature extraction method and system for human motion, and a recognition method and system. Background technique

[0002] Human motion recognition is a combination of sensor data collection and data mining technologies to realize the recognition and recording of human behavior. Human motion recognition has a wide range of applications, such as the recognition of routine life behaviors such as eating, watching TV, and rest, or gait recognition such as walking, running, and climbing stairs. Human motion recognition can bring many potential benefits and advantages to people's lives, for example, recording and monitoring exercise fitness, people's own health management or assisting in predicting behavioral intentions, etc., has been a research hotspot for scholars for many years.

[0003] Generally speaking, there are many ways to classify human body movements that can be used as rec...
