Detecting region tracks

Before you begin

See About region track detection for an overview before detecting region tracks.

You will need to create the 3D regions you will track. You can create these from multibeam data by detecting schools.

Detect region tracks

 To detect region tracks in a scene:

  1. Display the region class of interest in the scene.
  2. On the Scene menu, click Detect Region Tracks.
  3. The dialog box may appear with the following message:

    "There is no analysis variable and associated integration algorithm set for this scene. Echoview will track region geometric centers instead of centers of mass."

    If so,
    1. Click OK to track region geometric centers.

      - OR -
    1. Click Cancel.
    2. On the Shortcut menu (right-click), click Scene properties.
    3. Click the Analysis tab.
    4. In the Analysis variable list, select an analysis variable.
    5. Click OK.
    6. On the Scene menu, click Detect Region Tracks.
  1. On the Detect region tracks dialog box:
    1. Enter a Name for the Name of the region track group.
    2. In the Track regions of class list, select a region class.
    3. Enter the required Tracking settings.
    4. Enter the required Weights.
    5. Enter the required Track Acceptance settings.
    6. Click Detect.

If your detection is unsuccessful, reassess the settings you entered on the Detect region tracks dialog.
