Embodiment 1

[0052] Such as figure 1 As shown, the present invention provides a kind of gesture recognition method based on acceleration sensor, comprises the steps:

[0053] (1) Collect the acceleration data and angular velocity data of the user's hand movement through the sensor;

[0054] (2) Carry out Kalman filter to the data collected in step (1), remove the jitter interference and sensor clutter in the gesture process;

[0055] (3) Carry out the boundary detection of the action, use the correlation between the gesture action and the acceleration change, automatically judge the start and end points of the action, and intercept this section of action data as the judgment gesture this time;

[0056](4) Carry out high-pass filtering and low-pass filtering to the action data intercepted in step (3), filter out non-gesture action data, and further remove interference;

[0057] (5) Attitude calculation, calculate the angle between the sensor and the ground plane during motion according to...

Abstract

The invention discloses a gesture recognition method based on an acceleration transducer and belongs to the technical field of gesture recognition. The gesture recognition method disclosed by the invention can automatically judge a starting point and a finishing point of an action in a calculation process, without the intervention of external control. The gesture recognition method can eliminate gestures step by step, which do not accord with standards, in three steps (an included angle, a characteristic and a state), so that the total calculation amount is reduced; meanwhile, the probability of incorrect operation is also reduced. An action library characteristic is obtained through acquiring a plurality of gesture specimens, is input by a system, and cannot be automatically adjusted by an individual user. Although a requirement on characteristic differences of the gestures is high, the calculation amount is small, the recognition rate is high, the timeliness of an algorithm is improved, and rapid recognition can be realized at a low cost.

Description

technical field [0001] The invention belongs to the technical field of gesture recognition, in particular to a gesture recognition method based on an acceleration sensor. Background technique [0002] Smart wearable devices are one of the cutting-edge directions in the current manufacturing field. Motion recognition, including gesture recognition, is widely used in smart wearable devices. Acceleration sensors are applied to the field of gesture recognition technology to analyze the acceleration signals generated by human gestures. To detect and identify the user's motion state and realize the operation of the smart device. However, the current acceleration sensors used in the field of gesture recognition have shortcomings such as inability to accurately determine the start and end points of actions (or need to be manually set), unable to judge and screen out gestures that do not meet the standards, and cause misuse. Contents of the invention [0003] The object of the pre...
