摘要
提出一种适用于单相机的非穿戴式实时视线追踪新方法,并实现了一套样机系统.为提高视线追踪对使用者头动的适应性,提出一个头动自适应视线方向实时计算方法(ARGCMH).方法包含三个计算模型,它们在一套决策算法的控制下相互协调配合,实现视线追踪在一定范围内对头动的自适应,同时保持了适当的追踪精度和速度.实际测评给出了系统主要性能指标,并用一应用实例展现了系统的应用潜力.
A new approach of non-contact real-time gaze-tracking which is applied to single camera is proposed,and an example system is implemented. An Adaptive Real-lime Craze-direction Calculating Method for Head-movements（ARGCMH）is utilized to promote the adaptability of gaze-tracking. The calculating method is composed of three computing models and a decision al- gorithm. And the decision algorithm harmonizes the three models to make the gaze-tracking be adaptable to head-movements in a certain area and to maintain the tracking accuracy and frequency in an appropriate range. Main performances of the system are measured. An application embodies the applicable potential of the gaze-tracking system.
