How is the reconstruction of motion tracking calculated?
Reconstruction is calculated by how different objects move within the frame according to their distance to the camera, objects that are close to the camera will move faster than those far away. Motion tracking works best when the difference in the tracked object’s movement is clear.
Why is my 3D camera tracking my movement?
The 3D Camera Tracker will pick up my movement and think it’s tracking the movement of a static element in your scene, a feature. To avoid this happening, you have to first mask out any large moving foreground elements to remove them from your footage.
How to build a motion detection and tracking system?
This is the first post in a two part series on building a motion detection and tracking system for home surveillance. The remainder of this article will detail how to build a basic motion detection and tracking system for home surveillance using computer vision techniques.
Why is my camera tracker not working properly?
However, if the camera does not move around the scene very much, e.g. it is mainly a panning movement, the tracker cannot derive any depth information because there are no parallaxing objects in your shot.

How many tracked points should be included in a keyframe?
To do that the keyframe range should include at least 8 successfully tracked points and they should all be visible in every frame of the selected range. If you are unsure of what the best keyframe range is, let blender choose the right ones automatically, by enabling “keyframes”.
