Problems solved by technology

[0003] The above human eye positioning method can only determine the position of the pupil, but cannot accurately realize the positioning of other features of the human eye, such as the position of the corner of the eye, the geometric contour of the eye, etc., so the accuracy of the human eye positioning method in the prior art is not high

Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The invention provides a human eye positioning method, such as figure 1 As shown, the human eye positioning method of this embodiment includes the following steps:

[0029] Step S110, acquiring an image to be subjected to human eye positioning;

[0030] The image can be an image collected by the receiving monitoring terminal, or an image collected by calling a camera, or an image pre-stored on the terminal, or even an image intercepted from a video image. The image in this embodiment is a RGB three-channel color image, of course, the image may also be other images, such as a single-channel grayscale image and the like. The color image can also be in RGBA, YU...

Abstract

The invention discloses a human eye positioning method. The method comprises that the circular center and radius of the iris of the human eye is positioned, and the included angle between a connecting line between two corners of the eye and the horizontal direction of an image is positioned; initial values of other parameters of a preset energy function are obtained according to the circular center and radius of the iris and the included angle; and according to the circular center and radius of the iris, the included angle and the initial values of the other parameters, the energy function is minimized to obtain the contour of the human eye. The invention also discloses a human eye positioning device. Thus, the human eye positioning precision is improved, and human eye positioning is accelerated.

Description

technical field [0001] The invention relates to the field of computers, in particular to a human eye positioning method and device. Background technique [0002] Human eye positioning is widely used in identification, security monitoring, fatigue driving identification, digital image beauty of people, etc. The existing human eye positioning method generally includes: determining the range of the human face in the image; determining the range of the human eye according to the positional relationship of the features near the human eye and the positional relationship between the human face and the human eye; finally, within the range of the human eye Determine the position of the pupil. [0003] The above-mentioned human eye positioning method can only determine the position of the pupil, but cannot accurately realize the positioning of other features of the human eye, such as the position of the corner of the eye, the geometric contour of the eye, etc. Therefore, the accuracy...
