TIP Press ctrl and draw a rectangle over multiple points to select them. If any points are already selected,
they become unselected.
2 Enable Fixed Camera if you want to generate a fixed camera and a moving 3D point cloud.
Typically, 3D tracking results in a moving camera and fixed points, but you also can set the camera to
be fixed and the points to move.
3 Do one of the following:
■ Click Create Point Locators.
Selected point are converted to a point locators object with a parent axis. Double-click the newly
created point locators object to access its menu, where you can change display settings and enable
snapping. See
Using the Point Locators Object (page 667).
■ Click Create Axis.
Selected points are converted to axes with a parent axis. The axes synchronize to the results of your
3D camera tracking, and any further changes you make to the 3D track are reflected in these axes.
NOTE If you want to apply settings manually to a synchronized axis, change its name so that it does not
update automatically when Analyzer settings are changed. If you reset the Analyzer settings, the
synchronized axes become regular Action axes.
4 Use the created point locators or axes to view the reconstructed scene geometry or camera motion.
You can attach objects such as surfaces, 3D text, and 3D models to the new point locators or axes to
help position them in 3D space.
Output Settings
Fixed Camera button Enable to generate a fixed camera and a moving 3D point cloud.
Create Axis button Click to convert selected points to axes.
Create Point Locators button Click to convert selected points to a point locators object. Double-click the
new point locators node in the schematic to open the Point Locators menu.
Object Tracking
If the image sequence you are tracking has multiple moving objects, you can perform object tracking to
track these objects relative to the same camera. Since you perform camera tracking first, you can use the
camera data generated from the camera tracking analysis. For example, you can perform a camera tracking
analysis on the complete scene, then use masks or mattes to perform multiple object tracking passes focusing
on various moving objects in the scene. Each result can be converted to separate point clouds or axes, but
all results conform to the 3D camera synced to the original camera tracking.
NOTE To improve the results of the track, consider adding 2D manual trackers (page 648) either pre- or post-process.
To create an 3D track analysis based on object properties:
1 Create a camera track analysis, as explained in Camera Tracking (page 651).
2 Click Object Tracking to switch to the Object Tracking menu.
