一种基于会聚双目立体视觉的用户化身模型

在简单会聚式双目立体视觉模型的基础上,提出了具有9自由度的用户化身视觉模型用于虚拟场景的成像变换,导出了用虚拟场景点的世界坐标和用户化身视觉模型的9自由度变量表示的左、右双目虚拟摄像机的成像公式,求出了9自由度用户化身视觉模型的左、右双目成像的视差与场景点深度信息的关系及相应的计算公式。仿真实验结果表明了该模型的可行性和计算方法的可靠性,同时表明该模型比简单会聚式双目立体视觉模型更接近人的视觉习惯,因此更具有实用性。

A user avatar model based-on convergent binocular stereo vision

A vision model of user avatar with nine freedoms based-on simple convergent binocular stereo vision is proposed and used to imaging and transformation in virtual scene. The formulas of imaging in left and right virtual camera about the virtual scene points are educed with its world coordinate values and the nine freedoms variables of the user avatar vision model. The equations are deduced about the relationship between the parallax of the imaging points in left and right images about the scene point projected by virtual binocular camera and depth information of the scene point relative to the original points of the observation coordinate system. The results of the simulation experiment prove the feasibility of the model and the reliability of the algorithmic method in this paper. Simultaneously, it is proved that the vision model of user avatar with nine freedoms is more effective, more practical and more vicinal to human being's visional habit.
