【摘要】：针对人体在大空间范围内自由运动时视线方向难以追踪的问题,构建了一套基于光学跟踪设备的头戴式视线追踪系统。系统通过被动式光学追踪设备和头戴式眼部摄像机获取使用者的头部运动状态与眼部图像,然后依据初始标定结果来估计使用者自由运动状态下的视线方向;最后对系统进行简化,得到了适用于同类环境、与具体硬件设备无关的视线跟踪三点三面三变换几何模型。对系统进行应用实验和误差分析表明,使用者在3.0 m×3.2 m×2.0 m的大工作空间内自由运动时视线追踪误差为1.69°,频率为20 Hz。
[Abstract]:Aiming at the difficulty of tracking the direction of line of sight when the human body moves freely in large space, a head-mounted line of sight tracking system based on optical tracking equipment is constructed.The system acquires the head motion state and the eye image of the user through passive optical tracking device and head-mounted eye camera, and then estimates the direction of the user's line of sight in the free motion state according to the initial calibration results.Finally, the system is simplified, and a geometric model of line of sight tracking with 3.3 plane is obtained, which is independent of the hardware device and suitable for the same environment.The application experiment and error analysis of the system show that when the user moves freely in a large workspace of 3.0 m 脳 3.2 m 脳 2.0 m, the tracking error is 1.69 掳and the frequency is 20 Hz.
