三脚架

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.

Note

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.

关键帧

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.

改善

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.

焦距

Refine the camera's Focal Length.

光心

Refine the camera's Optical Center.

径向畸变

Refine the camera's Radial Distortion Parameters.

切向畸变

Refine the camera's Tangential Distortion Parameters.

清理

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.

Tracks or tracked segments shorter than this number of frames will be removed.

错误|误差

Tracks which has reprojection error higher than this value will be removed.

类型

Several actions can be performed for bad tracks:

选择

They can simply be selected.

删除轨道

The whole track can be deleted.

删除片段

Bad segments of tracked sequence can be removed.
