Chinese Abstract

介紹了一種基於瞳孔檢測的非強迫式注視點跟蹤系統。該系統對被測對象觀察不同注視點時的眼睛進行成像,通過圖像處理得到瞳孔在眼睛中的相對位置數據,從而計算出所觀察的注視點的位置。採用了二維定標算法進行系統定標,提出了一種角度修正的方法以提高系統精度。實驗結果表明,在相同的實驗條件下,系統估算點與實際觀測點基本一致,視角平均誤差為2.5º,可以滿足一般對注視點測定的要求。

English Abstract

A non-compulsory gaze tracking system based on pupil detection was introduced. The system takes the image of the eye of the tested subject when he is gazing at a position, and processes the eye image to get the relative position of the pupil in the eye, then calculates out the gaze position where he is gazing at. A two-dimension calibration algorithm is employed to calibrate the system, and an angle correction method is proposed to improve the precision of the system. The experimental results under the same conditions show that the calculated gaze positions by the system mostly agree with the real gaze positions, the average error of the view angle is 2.5º, so the system can meet the requirement of common gaze tracking.
