简介

In Tracking Mode there are three different views available. You can toggle between view modes using the View selector, which is located in the header. When you selected a view in the whole area of the Movie Clip editor will change. Hence, to display a curve or dope sheet view, the editor must be split into two, with one switched to the curve or dope sheet view.

所有摄像机录制的视频都会失真。由于光学透镜的工作方式，我们对此无能为力。为了使摄像机运动准确，需要修正焦距的精确值和畸变的“强度”。

在Blender中，您可以使用注释工具(蜡笔)来实现这一点——只需绘制直线在胶片上，然后调整扭曲值，使注释线条与胶片上的线匹配。

要更准确地校准相机，请使用OpenCV中的网格校准工具。opencv使用的是相同的变形模型，所以它不应该是一个问题。

解算完成后，需要让真实场景与3D场景相适应，以便可以更方便地进行合成操作。系统提供了用来指定地表平面、场景原点、以及X/Y轴的工具，以便能够执行场景匹配。

Sometimes, the video footage includes spurious jumps and tilting movements, like e.g. when using a hand-held camera. Based on some tracked image elements, the 2D稳像 is able to detect and compensate such movements to improve the quality of the final result.
