A Basic Planar Tracker
Match Move Workflow
Using the Planar Tracker is a process, but it’s straightforward once you’ve learned how to use it.
The following procedure tries to make this process as clear as possible.
To track a surface using the Planar Tracker:
1 Make sure the Operation Mode is set to Track, as you need to analyze an image to
track a surface before you do anything else.
2 With the background input of the Planar Tracker connected to an image, and the Planar
Tracker open in a viewer, move the playhead to a frame of video where the planar
surface you want to track is at its largest, is unoccluded, and is clearly a plane, and then
click the Set button in the Track panel of the Inspector to make this the reference frame
that will be used to guide the track.
Clicking the Set button to set the
reference frame to use for analysis.
3 Next, you’ll need to identify the specific pattern within the image that you want to
track. In most cases, this will probably be a rectangle, but any arbitrary closed polygon
can be used. The pixels enclosed by this region will serve as the pattern that will be
searched for on other frames. Please note that it is important that the pattern is drawn
on the reference frame. In this example, we want to track the wall behind the man, so
we draw a polygon around part of the wall that the man won’t pass over as he moves
during the shot.
Drawing a polygon to identify the part of the image you
want to track, which should be a flat, trackable plane.
TIP: Do not confuse the pattern you’re identifying with the region you’re
planning to corner pin (which always has four corners and is separately
specified in Corner Pin mode.
