MULTI-VIEW 3D VIDEO METHOD AND SYSTEM |
| 摘要 |
A multi-view 3D video method and system are disclosed. 3D points of an initial 3D model are projected back into back-projected points in image space. The back-projected points are compared with pixel points in next frames from multiple viewpoints. The pixel points in the next frames are updated according to comparing result between the back-projected points and the pixel points. Depth of the back-projected point is point-wise compared with depth of the corresponding pixel point. A farther point of the back-projected point and the corresponding pixel point, which are not similar in depth, are preserved, and the preserved farther point is used to update the pixel point in the next frame. |

1. A multi-view 3D video method, comprising:
providing an initial 3D model; projecting back 3D points of the initial 3D model into back-projected points in image space; comparing the back-projected points with pixel points in next frames from multiple viewpoints; and updating the pixel points in the next frames according to comparing result between the back-projected points and the pixel points; wherein the step for comparing the back-projected points with the pixel points comprises:
comparing depth of the back-projected point point-wise with depth of the corresponding pixel point; andpreserving a farther point of the back-projected point and the corresponding pixel point, which are not similar in depth, the preserved farther point being used to update the pixel point in the next frame. |
