| 摘要: |
| 描述了一种新的基于射影空间的视频增强方法,通过图像间对极几何约束以及基础矩阵关系,实现三维图形对象和视频叠加。该方法采用了Pinhole像机模型和射影几何约束条件方便地实现虚拟物体的重投影,而且不需要像机的标定参数和环境对象的3D位置,克服了仿射空间近似所带来的视觉误差和使用限制。 |

| Perspective-based Video Augmentation Approach |
|
| () |
| Abstract: |
| A new video-augmentation approach based on perspective space is described which makes use of epipolar constraints and fundamental matrix to realize superimposure of 3D image and video.It uses pinhole camera model and perspective geometry constraints to conveniently implement the reprojection of virtual objects.The approach does not use the calibration parameters of the camera and the 3D locations of the enviroment's object,and overcomes the vision errors and limitation of implementation because of the affine approximation to perspective. |
| Key words: virtual reality,video augmentation,video superimposure,epipolar line constraints,perspective space |
