虚拟视角自适应的视线矫正方法

Eye Gaze Correction Method Based on Virtual View Adaptation

  • 摘要: 针对远程视频会议中眼神缺失引起的沉浸感不足问题,提出一种普适化的基于虚拟视角的视线矫正方法.首先设计了一个能自适应用户不同位置的虚拟坐标系及基于此虚拟坐标系的几何模型,通过将实际坐标系下的三维点云数据转换到虚拟坐标系下并重投影到二维虚拟成像平面,能够达到矫正头部和视线的效果;在此几何模型下可自标定摄像机在虚拟坐标系中的位置,避免了用户参与虚拟摄像机模型中外参数的标定过程.实验结果表明,该方法可自适应设备的位置,矫正之后的图像能取得眼神直视的效果.

     

    Abstract: In order to solve the lack of eye-contact in remote video interaction, a new eye gaze correction method based on the virtual view under the pervasive environment has been developed.The method introduces a virtual coordination which is adaptive to different people's positions and a geometrical model involving the virtual coordination.It can adjust the eye gaze and the head posture through re-projecting three-dimensional cloud points onto a two-dimensional imaging plane.Meanwhile, under this geometrical model, it can do self-calibration for devices avoiding manual calibration of the virtual camera model's external parameters.Experimental results show the method enables self-calibration for devices, and the image after processing achieves the effect of eye contact.
