追踪
追踪面板 。
名称
轨道名称可以通过此字段进行更改。轨道名称用于将跟踪数据链接到其他区域,如Follow Track约束。
隐藏 ( 眼睛图标)
This toggle controls if the marker is enabled. If a marker is disabled, its position is not used either by solver nor by constraints.
锁定(锁上图标)
切换控制轨道是否被锁定。锁定的轨道根本无法编辑。这有助于防止对“已完成”的轨道发生意外更改(沿着整个素材镜头追踪准确)。
该面板中的小部件称为“轨道预览”,它显示样式区域的内容。这有助于检查功能被跟踪的准确程度(控制没有滑离原始位置),还有助于将轨道移回到正确的位置。通过拖动鼠标可以直接使用此小部件移动轨道。
有预览插件可用于放大预览构件的垂直尺寸(面积的显示使用两条水平线)以下的小面积。
更多选项
R(红), G(绿), B(蓝)通道
跟踪发生在灰度空间中,因此该特征与其背景之间的高对比度会产生更精确的跟踪。在这种情况下禁用某些颜色通道可能会有所帮助。
灰度预览 (B/W)
即使启用了所有通道,也会将预览图像显示为灰度。
遮罩预览(黑白图标)
应用由预览窗口中的标注工具定义的遮罩。
权重
改变问题跟踪标记的权重可以纠正或大大减少随着特征消失或变得难以跟踪的不合需要的跳跃。
Another use of Track Weights is when you want to reconstruct a scene from your camera solution. In that case you can first carefully track and solve your scene, and once you are done, lock all your markers with Ctrl-L, set the tracker weight in the Extra Settings of the tracker settings to zero and use the feature detection to quickly add lots of markers. Now track them and solve the scene again. Since their weight is zero they will not influence your solution at all, but you will have lots of good reference points in your scene.
稳重
权重 参数用于三维重建,稳定权重 用于控制二维稳定。
Custom Color Presets
自定义颜色 的预设。
自定义颜色
This setting overrides the default marker color used in the Clip editor and 3D Viewport, and it helps to distinguish different type of features (for example, features in the background vs. foreground and so on). Color also can be used for “grouping” tracks so a whole group of tracks can be selected by color using the Select Grouped operator.
要选择好点进行跟踪,请使用素材时间线中间的点并从那里向后和向前跟踪。这将提供更大的机会留在相机镜头中。
