利用基于图像处理技术的视线方向识别、跟踪方法,通过近红外光线在眼睛角膜反射产生的光斑和瞳孔中心的位置关系来确定视线方向,推导出人眼在计算机屏幕上的注视点,进而实现人眼对鼠标的定位与操作,其在显示屏上定位精度可达到40×40像素.
Using the direction of line of sight recognition and tracking method based on the image processing technology, the direction of the line of sight is determined by the position relation between the light spot and the pupil center produced by the reflection of near-infrared light on the cornea of the eye and the gaze point of the human eye on the computer screen is deduced, Eye on the positioning and operation of the mouse, the positioning accuracy of the display can reach 40 × 40 pixels.
