穿戴式视线追踪系统研究

Wearable Eye Tracking System

为了克服头动对于视线追踪效果的影响,论文提出了一种穿戴式的视线追踪系统。穿戴式的优势在于摄像机与人眼的距离始终保持相对不变。要实现精度高、实时性好的视线追踪系统,系统首先是对头部运动进行检测,然后对眼部进行特征提取。这里使用亮瞳孔技术,瞳孔-角膜反射的原理,应用特制的红外线摄像头捕捉眼球的运动,分析眼球运动轨迹和注视时间。最后,通过头部运动参数联合视线追踪数据,得到准确的视线定位。

In order to overcome the effects of head movement to track the impact of the line of sight,this paper proposes a wearable eye tracking system.The advantage of the wearable is the distance between the camera and the human eye remaining relatively unchanged.To achieve high accuracy,good real-time eye tracking system,the system detects head movement firstly,then extracts features of eyes.Bright pupil technology,pupil— corneal reflex principle are used,a special infrared camera is applied to capture eye movements,trajectory and fixation time are analyzed.Finally,by the head movement parameter joint eye tracking data,accurate position of sight is got.
