摘要
为开展视点定位与跟踪研究,实现单摄无光源的基于视点跟踪技术的人机交互系统,文章利用质心法来进行瞳孔定位,并使用几何模型映射方式校准人眼状态和屏幕坐标的对应值,最后实现了较为准确的视点坐标提取与追踪及相应的应用功能。该算法简单易行,具有较高稳定性和准确性,可应用于AR、VR等设备进行辅助操控,也可应用于医疗护理等领域,辅助失能人士进行有效操控,提高其生活质量和便利性。
Objective to research on gaze positioning and tracking,and implement an human-computer interaction system based on gaze-tracking with a single camera of no light source.Method the average-force algorithm is used to locate pupils,and geometric model mapping is used to calibrate the corresponding value of human eye state and screen coordinates.Result the accurate gaze positioning and tracking with according application functions are implemented.Conclusion the proposed algorithms are easy to be realized with high stability and accuracy,with can be applied in AR,VR devices for auxiliary control,or in medical and nursing fields to facilitates the disabled to realize effective control,to improve their life quality and convenience.
