Computed 2D points
 
 
 

The tracker automatically creates and places computed 2D points, using information from the key points, in the sequence, that are used in the camera solving process. The type of computed point generated depends on the type of tracking process that you run to create them.

There are three types of computed 2D points shown by the following symbols that appear in the Track window.

Shape Type of Point
 

Forward computed point

 

Backward computed point

 

Bi-directional computed point

Clearing computed points

  1. Select a track(s) and then a frame(s) range.
  2. Do one of the following:
    • Select 2D Tracking > Clear Tracked Points.
    • Right-click 2D View, the Point Tracks folder in the Project window or the Track window to show the pop-up menu and select Clear Tracked Points.
    • Press the Backspace key.

If you have not created a time range, MatchMover deletes the point at the current time. If you have created a time range, MatchMover deletes all points within the range.

Locking tracks

Locking a track protects a track against modification or deletion. For example, a locked point will not be removed from the project when you cleanup the tracks.

To lock a track:

  1. Select a track(s).
  2. Enable Locked. In the Project window and Track window, you will also notice that the track point is now represented with a lock.

A Locked icon appears beside the corresponding point track in the Project window and the Track window indicating that the point track is locked. Alternatively, simply right-click a track point in the 2D View or in the Point Tracks folder in the Project window or the Track window and in the pop-up menu, select Locked.

Track color display

Each track is displayed with a specific configurable color, either in 2D or 3D Mode. If the track color is the default one (black), it's displayed as such.

If a custom color is set, then this color will be used for the 2D label, the 2D track and the corresponding 3D helper (3D reconstruction).
