【摘要】：針對人體在大空間范圍內自由運動時視線方向難以追蹤的問題,構建了一套基于光學跟蹤設備的頭戴式視線追蹤系統(tǒng)。系統(tǒng)通過被動式光學追蹤設備和頭戴式眼部攝像機獲取使用者的頭部運動狀態(tài)與眼部圖像,然后依據初始標定結果來估計使用者自由運動狀態(tài)下的視線方向;最后對系統(tǒng)進行簡化,得到了適用于同類環(huán)境、與具體硬件設備無關的視線跟蹤三點三面三變換幾何模型。對系統(tǒng)進行應用實驗和誤差分析表明,使用者在3.0 m×3.2 m×2.0 m的大工作空間內自由運動時視線追蹤誤差為1.69°,頻率為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 擄and the frequency is 20 Hz.
