Abstract

The embodiment of the invention provides a method for determining an eye state. A template for the eye state can be accurately and rapidly determined in real time, and therefore the eye state is accurately and rapidly determined. The method comprises the steps of: obtaining an eye image of a target object; selecting a first eye image from the eye image, wherein the proportion of a sclera region in the first eye image showing sclera is more than or equal to a preset value; and determining the eye state of the target object in the second eye image according to the first eye image. According to the method and the device for determining the eye state, provided by the embodiment of the invention, the eye opening template is determined according to the proportion of the sclera region in the eye image showing the sclera, and can be accurately and rapidly determined in real time, thus the eye state can be accurately and rapidly determined according to the eye opening template.

Description

Technical field [0001] The present invention relates to the field of image processing, and more specifically, to a method and device for determining eye state. Background technique [0002] At present, digital camera equipment has been widely used. When shooting, due to environmental factors such as improper grasp of the photographer, changes in the subject’s mood, or light, the captured image may contain the subject’s eyes closed or squinted. Those who bring troubles. Therefore, in order to avoid this situation, many digital camera equipment have introduced blink recognition technology, that is, when shooting, the human eyes in the scene are detected to determine whether there is blinking, and if it occurs, it will automatically delay the photo. Or remind the photographer to take another photo. As a method of blink recognition technology, a template matching method can be used, that is, based on an online or offline generated eye template, it is determined whether the subject ...
