System and process for geometry replacement |
摘要 |
A system and process for replacing unwanted geometry (for example, tracking markers) in a recorded scene with new geometry. A 3-D matchmove process creates a 3-D map. The 3-D map is used to determine the 3-D coordinates of objects within the recorded scene. The 3-D coordinates of the tracking markers (and/or other objects) and the replacement portions are converted by a conversion means to 2D screen space coordinates of pixels that make up both the tracking markers (and/or other objects) and the replacement portions. A list comprising the 2D screen space pixel coordinates is then exported from the conversion means into a compositing application which reads the list of 2D pixel coordinates and makes the desired replacement automatically from frame-to-frame. Tracking markers (and/or other unwanted objects) are replaced with replacement portions with suitable characteristics.
