Embodiment Construction
[0021] In view of the problems in the prior art, the embodiment of the present invention proposes a method for identifying the motion state of the human body. The method extracts important parameters representing the motion state of the human body from the raw data output by the acceleration sensor and the magnetometer. Through these The characteristic parameters analyze the movement range and frequency of the human body in different motion states and detect changes in the magnetic field environment around the human body, thereby realizing fast, real-time and accurate analysis of the motion state of the human body.
[0022] In order to further illustrate the technical idea of the present invention, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the em...

The invention discloses a method for identifying the movement state of a human body, which is applied to an intelligent mobile device comprising an acceleration sensor and a magnetometer. The method specifically includes: determining a jerk and a mean zero-crossing point rate of a human body carrying the intelligent mobile device according to an acceleration value output by the acceleration sensor; and determining the geomagnetic inclination of the current area in which the human body is according to a magnetic field strength value output by the magnetometer. When the movement state of the human body is recognized by the intelligent mobile device, the method integrates the acceleration sensor and the magnetometer to statistically analyze the amplitude and the frequency of the movement of the human body under different motion conditions and detect the data of the changes of the magnetic environment in which the human body is so as to realize quick, accurate and real-time recognition ofthe movement state of the human body.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for identifying the motion state of a human body, and also relates to an intelligent mobile device. Background technique [0002] With the development of science and technology, people pay more and more attention to their own health status, and record their exercise status at all times to provide help for people's exercise quantification and health awareness, but the human body movement is complex and has many states. There are many parameters and the model is complex, which requires a large amount of data, large memory and high power consumption. Therefore, such methods are often run and analyzed offline in the computer. However, the memory and power consumption of smart mobile devices are relatively limited, and the online real-time analysis of the motion state puts forward higher requirements for the efficiency of the algorithm. [0003] And the current smart ...
