- Chân Máy Ảnh (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.
Ghi chú
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 (Khung Khóa)
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.
- Khung Khóa A/B (Keyframe A/B)
Start (A) and End (B) frame of the range used for reconstruction.
- Tinh Chỉnh (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.
- Tiêu Cự
Refine the camera's Tiêu Cự (Focal Length).
- Quang Tâm (Optical Center)
Refine the camera's Quang Tâm (Optical Center).
- Biến Dạng Tỏa Tròn (Radial Distortion)
Refine the camera's Tham Số Biến Dạng Xuyên Tâm (Radial Distortion Parameters).
- Biến Dạng Tiếp Tuyến (Tangential Distortion)
Refine the camera's Tham Số Biến Dạng Tiếp Tuyến (Tangential Distortion Parameters).

Dọn Dẹp (Cleanup)#
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.
- Số/Khung Hình (Frames)
Tracks or tracked segments shorter than this number of frames will be removed.
- Lỗi/Sai Số (Error)
Tracks which has reprojection error higher than this value will be removed.
- Thể Loại (Type)
Several actions can be performed for bad tracks:
- Lựa Chọn (Select)
They can simply be selected.
- Xóa Giám Sát (Delete Track)
The whole track can be deleted.
- Xóa các Phân Đoạn (Delete Segments)
Bad segments of tracked sequence can be removed.
