Embodiment Construction

[0033] The scope of applicability of the present invention will become apparent from the detailed description given below. It should be understood, however, that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given for purposes of illustration only.

[0034] figure 1 An embodiment of the method of the present invention is shown, the method is used for detecting and locating the eyeball and tracking the movement track of the same eyeball. Eyeball detection is to locate the position of the eyeball in the image from the captured imaging image of a continuous image sequence that may contain the eyeball. The eyes, distinct from the skin, have very distinct shape and color features. In order to ensure the real-time performance of the algorithm, the method of this embodiment uses image preprocessing and image segmentation algorithms combined with prior information to realize eye positioning. Eye tracking is to analyz...

Abstract

The invention discloses an eye movement detection tracking method and device, and an application of the eye movement detection tracking method. The eye movement detection tracking method comprises that a continuous image sequence which can include an eyeball is captured; a target rectangle of a candidate eyeball is detected and positioned in imaging pictures of the image sequence; non eyeball positioning is removed, and the tracked eyeball target rectangle is obtained; a hash code calculating step is carried out, during one frame of the image sequence, the whole image is scanned, and the hash code of each scanning window is calculated; a comparison step is carried out, the Hamming distances of each calculated hash code and the hash code of the tracked eyeball target rectangle are compared, and the eyeball target is on the scanning window having the minimum Hamming distance in the current frame; the eyeball target rectangle to be tracked in the next frame is updated through the eyeball target rectangle in the current frame, the hash code calculating step and the comparison step are repeated until an eyeball target rectangle coordinate sequence of N frames is obtained; and the eyeball moving angle is calculated according to the coordinate sequence. According to the invention, eyeball movement can be detected and tracked accurately.

Description

technical field [0001] The present application relates to the field of electrical digital data processing, and in particular to an eye movement detection and tracking method and / or device for detecting and locating the position of the eyeball in an imaging image and analyzing and detecting the movement trajectory of the eyeball within a certain period of time. The present application also relates to the use of the aforementioned eye movement detection and tracking method for controlling the operation of an application such as a player application. Background technique [0002] In today's information society, the influence and effect of the development and application of information technology and information industry represented by multimedia on human society are becoming more and more obvious and important. The development and application of multimedia has greatly promoted the mutual penetration and rapid development of many industries, and gradually changed the work struct...
