Problems solved by technology

Therefore, in the process of implementing the above method, the requirements for hardware memory and performance are relatively high, which increases the overall cost of the product.
In addition, the long-term heavy-duty calculation and storage processing operations also cause a relatively large loss of hardware, which increases the failure rate of the product and greatly reduces the service life

Abstract

The invention relates to an eye blink recognition method and device. The method comprises the steps of sampling a signal meeting a preset sampling condition in a voltage signal output by a body motion detection chip to obtain a sampling data sequence; choosing any sampling point from not traversed sampling points as a target sampling point; when the target sampling points meet a preset blink sampling point effective condition, creating a cluster aiming at the target sampling points; adding the target sampling points and sampling points, meeting a clustering condition, among the target sampling points into the cluster; repeatedly executing the step of choosing any sampling point from the not the traversed sampling points as the target sampling point till all sampling points in the sampling data sequence are traversed; according to the established cluster, recognizing a blink parameter. Through the technical scheme, the calculation amount of data can be reduced, the complexity of an algorithm is lowered, an error which possibly occurs in the calculating process is effectively avoided, and the accuracy is drastically improved.

Description

technical field [0001] The present disclosure relates to the field of eye blink detection, and in particular, to a method and device for eye blink recognition. Background technique [0002] The body motion detection chip integrates a whole set of circuits with electromagnetic wave transmitting and receiving functions into one chip, which is used to detect human body movements. Its advantages are small size, low power consumption, and easy to use. Its basic principle is to emit electromagnetic waves to the outside world and detect the reflected electromagnetic waves, and output the detection results in the form of voltage. When the body motion detection chip is working, transmitting and receiving electromagnetic waves is a continuous process, and its output voltage is also a process of continuous change. When no human motion is detected, the output voltage is stable within an extremely small range of values; when human motion is detected, the output voltage fluctuates, and t...
