Method and device for detecting blink motion, readable storage medium and electronic device

Abstract

The invention relates to a method and a device for detecting blink motions, a readable storage medium and an electronic device. The method comprises: sampling signals output by a plurality of body movement detection chips used for detecting blink actions; when a voltage value of a sampling point of any body movement detection chip is larger than a first threshold, according to sampling point dataof each body movement detection chip in a preset duration from the moment corresponding to the sampling point, respectively determining actual values of various blink characteristic parameters corresponding to each body movement detection chip; aimed at each body movement detection chip, matching the actual values of a target blink characteristic parameter group corresponding to the body movementdetection chip with ideal values of the group of target blink characteristic parameters corresponding to each body movement detection chip; when proportion of the number of successfully matched body movement detection chips and the total number of the body movement detection chips is larger than or equal to a second threshold, determining that a subject has a blink motion. Therefore, real-time property and accuracy of a detection process can be guaranteed, and applicability is wider.

Description

technical field [0001] The present disclosure relates to the field of eye blink detection, and in particular, to a blink detection method, device, readable storage medium, and electronic equipment. 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...

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
