Step 2. Set Mocap Zone

The second step in the setup process is to calibrate MOVIN TRACIN so that it can accurately understand the layout of your physical space.

Brief Introduction to the Display

Display of Step 2. Set Mocap Zone

  • Center Panel

    • First Row: Front and Side views

      • Each view displays the ground-level point cloud captured by TRACIN from the front and side perspectives.

      • A gray reference box is centered in each view, serving as the alignment boundary for accurate ground leveling.

      • Points within the gray box are shown in green, while those outside appear in red, indicating misalignment.

      • The currently selected view is highlighted with a green border.

    • Second Row: 3D view

      • A white 3D cube outlines the motion capture zone, representing the capture volume TRACIN uses to detect and record movement.

      • Points inside the capture volume are highlighted in red, signaling that the area must be cleared before starting the session.

  • Right Sidebar Options:

    • Click “Front View” or “Side View” to select a perspective and adjust the point cloud accordingly.

    • Use the navigation buttons to move the point cloud vertically or rotate the view.

    • Adjust the Height slider to set the vertical size of the capture volume.

    • Drag the border lines to resize the width and length of the capture volume.

    • Drag the circle to reposition the center of the mocap zone.

Leveling: Aligning the Point Cloud with the Reference Box

Move and rotate the point cloud to align it with the gray reference box. Repeat the adjustment in both front and side views for optimal accuracy.

The goal is to position the point cloud as accurately as possible within the gray reference box.

  • indicate areas that fall outside the gray reference box.

  • Use the rotation buttons to correct any tilt in the selected view.

  • Use the translation buttons to move the point cloud up or down as needed.

  • Switch between front and side views to adjust from both perspectives.

  • Repeat the alignment process until most points appear green in both views.

Mocap Zone Setting

  • The minimum distance from TRACIN to the mocap zone is 1m.

  • The minimum width and length of the Mocap Zone is 1m x 1m.

  • The maximum width and length of the Mocap Zone is 5m x 5m.

  • The center of the mocap zone can be positioned between 1.5m and 5.5m from TRACIN

  • The near and far borders automatically adjust to stay within the 2.5m maximum distance from the center.

  • The maximum distance from the center to the left and right borders is also 2.5m.

  • The capture volume height ranges from 2 meters to 3 meters.

If the point cloud includes your ceiling, adjust its height to exclude it.
Move the center of the mocap zone and adjust its borders to fit within your space.
If there are any immovable objects within the zone, adjust the zone boundaries to exclude those areas.
If there are red markers indicating obstacles in your zone, you cannot proceed to the next step. Try re-leveling, removing any movable objects, and saving again to verify that the zone is clear.

Recommended Steps for Setting Up the Mocap Zone

1

The minimum distance from TRACIN to the mocap zone is 1m

Check this first.

2

Get rid of all objects/obstacles from your mocap zone.

If somethings there, you might got red alert.

Red points inside the capture volume indicate that the area must be cleared before starting the session.

3

Drag the border lines to resize the width and length of the capture volume.

4

Drag the center circle to reposition the center of the mocap zone.

5

Click the 'save' button to store the zone setting.

If red points are present, either remove the obstructing objects or adjust the border lines to exclude the occupied area.

6

If the area is clear, the next button will appear to proceed to the next step.
