AI Technical Summary

Problems solved by technology

If the sensor is shaken or the sensor is worn in different positions on the human body and the original signal changes, the values ​​of these time-domain features will generally change greatly, which will affect the recognition system's classification of actions.
For the frequency domain characteristics of the signal, although it has a certain anti-interference ability, because its calculation involves FFT transformation, the amount of calculation is large, which is not conducive to the realization of real-time action recognition system

Embodiment Construction

[0063] The present invention will be further described below in conjunction with the accompanying drawings.

[0064] The hardware device implementing the present invention includes a wearable device equipped with a bluetooth transmission function and a three-axis acceleration sensor, and a PDC or computer with a bluetooth receiving function. The identification method of the present invention runs on the PDC or computer in the form of application software by means of software programming. During the implementation process, using the sensor device worn on the human body, the acceleration signals of various actions can be transmitted to the computing device in real time through Bluetooth, and then the signal data is processed correspondingly through the recognition software to realize action recognition.

[0065] The system structural block diagram of the present invention is as attached figure 1 As shown, the specific steps are as follows:

[0066] (1) After receiving the sign...

Abstract

The invention provides a weight loss feather extraction method based on an acceleration transducer, comprising the following steps: (1) receiving the measuring data of an acceleration transducer; (2) according to the measuring data, vertically correcting accelerated speed to obtain net accelerated speed after removing gravity in the vertical direction; and (3) according to the net accelerated speed obtained in step (2), detecting the state of weight loss, and extracting weight loss feather data.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition, in particular to a weightless feature extraction method in motion recognition based on an acceleration sensor. Background technique [0002] Action recognition is one of the central tasks of the intelligent system. Its technical goal is to realize the perception and identification of the type of action, action intention or other motion attributes of the actor through monitoring and sensing a series of actions of the actor under certain environmental conditions. . [0003] The action recognition technology based on sensors (especially acceleration sensors) has relatively low requirements on the use environment and system hardware, so it has been widely used in the field of human action recognition. In order to improve the classification efficiency of the system, the general action recognition method will include the step of feature extraction. Among them, the time-domain features tha...
