Problems solved by technology

In this method, the use of auxiliary light sources will limit the use of the scene. On the other hand, because the segmentation and positioning of the eyelids is difficult, it is usually necessary to count the up and down motion areas in the sequence frame images to finally determine the eyelids, resulting in increased computational complexity.

Abstract

The invention provides an eye opening or closing state detection apparatus and method. The eye opening or closing state detection apparatus comprises an eye region detection unit which detects an eye region containing eyes in a target image, an eye division unit which divides the detected eye region to extract an eye image, and a state determination unit which determines whether the eyes are opened or closed based on the gray change in the eye image.

Description

technical field [0001] The present application relates to a device and method for detecting the state of opening and closing of eyes. More specifically, it relates to a detection device and method for detecting blinking by determining the state of detecting eye opening and closing. Background technique [0002] Eyes are the main window for human beings to obtain information from the outside world, and the information it receives accounts for 80% to 90% of all information received by the brain. The research of human eye gaze tracking technology has far-reaching significance in the fields of cognitive science, psychology, human-computer interaction and so on. [0003] Blink detection technology refers to the image detection of some characteristics in the process of human eye movement, estimating whether the eyes are currently closed or open, and the degree of eye opening. With the popularization and development of video processing and video surveillance technology, eye blink...
