Using a Target

Register the target to be used in the MREAL space to the system with the following procedure.

When using a target using a sensor, see “Registering the Target Using a Sensor”.

Registering the Target

Preparation

  • Print multiple markers. For details on printing, see “Printing Markers”.
  • Affix the printed markers to the target for superimposing a CG image. When doing so, determine which marker is to serve as the origin of the target (origin marker).

Registering the Target

  1. Select [Target] in [Option Settings] of the MREAL Configuration Tool window.

  2. Select [Add] in [List of Targets].

  3. Enter the target information.

    • Select the ID number and enter the name of the target to be registered in [1. Information Input] of the screen below.

Registering the Origin Marker

Register the origin marker affixed to the target.

  1. Select [On] in [MREAL Marker] of [2. Select Tracking Method].

  2. Click [Start Tool] in [3. Calibration of Coordinate System].

    • The Marker tool window appears.

  3. Right-click the registered target name on the [Edit Mode] tab, and select [Add MREAL Marker]

  4. Enter the information for the origin marker in the Add MREAL Marker window.

    • Select [Origin Marker] in [Input Type].
    • Enter the number on the printed origin marker in [Marker ID].
    • Enter the size (side length) of the printed origin marker in [Size].
    • When input is finished, click [OK].

Registering the Other Markers

When the size of the origin marker is the same as that of the other markers, register the other markers with the following procedure.

  1. Select the registered target name, then right-click and select [Add MREAL Marker Collectively].

    • Enter the marker ID and size for the other markers.
    • When input is finished, click [OK].

  2. Click [Apply] in the Marker Tool window.

Note

  • When the size of the origin marker differs from that of the other markers, the registration work of the other markers is not necessary.

Calibrating the Registered Markers

Perform calibration so that the markers affixed to the target are tracked.

  1. Select the [Calibration Mode] tab in the Marker Tool window.

  2. Capture the marker with the MREAL Display.

    • Align the target within the screen, and click [Grab] to capture an image. With the MREAL X1/S1, you can capture an image by pressing button <B>.
    • Changing the angle of the target, capture images of all markers affixed to the target.
    • Check that [Good] or [Excellent] is displayed in the [Calibration Determination] column. If [Good] or [Excellent] is not displayed, repeat capturing.
    • When capturing is finished, click [Calculate].

  3. When the following window appears, click [Close].

    • The coordinate system of the target is defined, and the tracking of the target becomes possible.

  4. Click [Apply] then [OK] in the Marker Tool window.

  5. Click [OK] in the MREAL Configuration Tool window.
