Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with specific embodiments. The implementation process of the embodiment of the present invention includes three steps of face detection, pupil positioning and distance control.

[0021] 1 face detection

[0022] This embodiment adopts the method proposed by Paul Viola and Michael Jones to detect the face information captured by the imaging device in the electronic device (note: this embodiment requires that the face must face the screen of the electronic device and the face is not tilted). If multiple faces are detected at the same time, the face information closest to the middle of the image is used for subsequent distance control.

[0023] 2 Pupil positioning

[0024] The pupil positioning method proposed in this embodiment includes the following steps:

[0025] (1) Initially determine the approximate position of the human eye

[0026] As we all know, the relative position of the various organs of the human...

Abstract

The invention provides a method for controlling the distance between eyes of a user and the screen of electronic equipment in a computer vision and image processing mode. The method comprises the steps of face detection, pupil positioning, pupil distance computation and distance control. When the distance between the user and the screen of the electronic equipment is judged to be too short, prompting information is transmitted to require the user to adjust the distance between the eyes and the screen of the electronic equipment. Due to the application of the technology, the hardware cost of the electronic equipment cannot be increased, and the effect of protecting the vision of the user can also be achieved.

Description

Technical field [0001] The invention belongs to the technical field of pattern recognition, and in particular relates to a method for controlling the distance between the user's eyes and the screen of an electronic device by means of computer vision image processing. Background technique [0002] At present, the method of controlling the distance between the user and the electronic device is basically based on some special devices, such as infrared sensor, ultrasonic sensor, etc. These technologies increase the complexity of the hardware system of the electronic device to a certain extent. , Its cost will also increase. The present invention proposes a method for controlling the distance between the user’s eyes and the screen of the electronic device by image processing for those new electronic devices with imaging devices. Compared with other technologies, this method does not increase the cost of the electronic device. Hardware cost. [0003] On the other hand, in the field of ...
