Terminal and remote control method thereof

Abstract

The invention discloses a terminal and a remote control method thereof. The method comprises the steps as follows: at least two frames of images of a user in a set area are acquired, and face positioning of the images is performed; according to double-eye reference positions which are established in advance, pupil positioning of the face images is performed, and the movement conditions of pupils are determined according to positions of the pupils; remote control instructions corresponding to the movement conditions of the pupils are looked up and executed from operation strategies, so that corresponding operation functions are realized; and a process for establishing the double-eye reference positions is as follows: a double-eye opening image and a double-eye closing image of the user in the set area are acquired, and the double-eye reference positions are established according to the difference of vertical gray-level projection histograms of the double-eye opening image and the double-eye closing image. Compared with a conventional pupil tracking technology, the terminal and the method improve the pupil positioning accuracy; the problem that in a process that the terminal is controlled remotely through the pupil movement, the pupils are not positioned accurately, so that the terminal identifies the pupil movement mistakenly is solved; and misoperation, caused by identification errors, of the terminal is reduced; and an experience effect of the user is improved.

Description

technical field [0001] The invention relates to the field of human-computer interaction technology, in particular to a terminal based on pupil tracking technology and a remote control method thereof. Background technique [0002] At present, the remote control of TV can be divided into two categories, one is based on equipment, such as remote control / mobile phone / point reading pen, etc.; the other is based on the user's body and behavior itself, that is, no external equipment is needed, such as gesture / voice / idea etc. Device-based remote control involves direct involvement with the device. Without the device, no remote control can be performed. It has a mandatory prerequisite. This mode is less and less suitable for modern smart furniture life; remote control based on the user itself is now However, each method has its own advantages and disadvantages. For gesture-based remote control, users are prone to fatigue when they keep raising their hands. Voice operations are easi...

Problems solved by technology

[0006] The existing method of positioning the human eye twice, when determining the approximate position of the human eye, is only determined according to the difference between the eye and the surrounding skin color, which is not very accurate, that is, the existing technology can only determine the place where the skin color is different It is not the user's face, but it is not sure that the place must be the eye, because it is likely to be inaccurate due to interference factors such as eyebrows, long hair, or makeup effects
