沉浸式虚拟环境(IVE)系统中三维(3D)凝视和深度感知的研究是一个重要的研究领域。已经提出了几种方法,但从未报道过在 IVE 中使用凝视屏幕信息进行深度感知测量。我们提出了一种使用几何模型来测量 IVE 中深度感知的新方法。我们从双目凝视屏幕映射中扩展信息,并通过线交叉方法获得深度信息。我们还通过眼部摄像头对准和前/后屏幕条件来研究深度感知的误差。我们的仿真结果表明,该方法的 2D 视线跟踪估计误差低于 1°,并且在屏幕前/后屏幕深度 ±0.6 至 ±1 米的情况下,深度测量精度超过 84%。作者
Study of three-dimensional (3D) gaze and depth perception in immersive virtual environment (IVE) systems is an important research area. Several approaches have been proposed, but the usage of gaze-screen information for depth perception measurement in IVE has never been reported. We suggest a new approach using geometric model to measure depth perception in IVE. We extend information from binocular gaze-screen mapping and obtain the depth information by line-crossing method. We also investigate error of depth perception by eye camera alignment and front/behind screen condition. Our simulation results show that the 2D gaze tracking estimation error of the proposed method is lower than 1° and yields depth measurement accuracy more than 84% on ±0.6 to ±1 meter depth of front/behind screen condition.
