Трек-плоскость (plane track)¶
Solve¶
- Tripod
Tripod Motion can be used for footage where the camera does not move and only rotates. Such footage can’t be tracked with a generic solver approach, and it is impossible to determine the actual feature points in space due to a lack of information. So this solver will solve only the relative camera rotation and then reproject the feature points into a sphere, with the same distance between feature and camera for all feature points.
Примечание
This is special type of camera solver and it behaves different from regular solver. It means using more tracks doesn’t imply more accurate solution. Having 5-10 tracks on frame is likely what shall be commonly used for this kind of solver.
- Keyframe (Ключевой кадр)
Automatically select keyframes for initial reconstruction. This option enables complex algorithms which tries to find a keyframe pair with minimal reconstruction error and best scene scale guess.
- Keyframe A/B
Start (A) and End (B) frame of the range used for reconstruction.
- Refine
Specifies which parameters should be refined during solve. Such refining is useful when you are not sure about some camera intrinsics, and solver should try to find the best parameter for those intrinsics. But you still have to know approximate initial values – it will fail to find correct values if they were set completely incorrectly initially.
- Фокусное расстояние (focal length)
Refine the camera’s Focal Length.
- Optical Center
Refine the camera’s Optical Center.
- Radial Distortion
Refine the camera’s Radial Distortion Parameters.
- Tangential Distortion
Refine the camera’s Tangential Distortion Parameters.
- Solve Camera/Object Motion
See Solve Solution.
Привести в порядок (clean up)¶
This panel contains operators and their settings which are needed to clean up bad tracks: tracks which are not tracked long enough or which failed to reconstruct accurately.
- Кадры (frames)
Tracks or tracked segments shorter than this number of frames will be removed.
- Ошибка (error)
Tracks which has reprojection error higher than this value will be removed.
- Тип (type)
Several actions can be performed for bad tracks:
- Выделить (select)
They can simply be selected.
- Delete Track
The whole track can be deleted.
- Delete Segments
Bad segments of tracked sequence can be removed.
- Clean Tracks
See Clean Tracks.
- Filter Tracks
See Filter Tracks.
