Head & Face Scan Tutorial

In this tutorial, you will complete a single cylindrical scan of a human subject using a Cyberware Head & Face scanner and the CyScan software. Further information on each of the commands and menu items is available in the Reference Section of the CyScan User Guide.

  1. Double-click the cyscan icon to launch the program.
  2. This action will open the program window as illustrated below:

    cyscan Main Window
  3. If necessary, select a Head & Face scanner.
    1. Choose Scanner | Select Device....
    2. [cyscan]
      Scanner Menu
    3. Double-click the Head & Face Scanner (Model PX or Model PS) in the Choose a Scanner dialog.
    4. [cyscan]
      cyscan Main Window
  4. Position the Subject
  5. Place the scan subject as near to the center of the motion platform as is possible. It is not necessary to have the subject in the exact center, but the best results are achieved, in most cases, when the subject is properly centered.

    For more information on positioning the scan subject, please refer to the Scan Preparation section of this user guide.

  6. Adjust the Scan Parameters
  7. The appropriate settings should be made in the Scan Setup window to capture the image. These settings will tell the scanner the length of scan to acquire and at which sampling pitch.

    Open the Scan Setup window by clicking on the Setup button at the bottom-left of the main cyscan window.

    [Scan Setup Button]
    Scan Setup Button

    You will see a window similar to the following open on the desktop:

    [Scan Setup Button]

    1. Texture
    2. The texture setting tells the digitizer to capture the subject's luminance or color values, or to ignore them. In this example, we have no need of the luminance or color data, so select None.

    3. Arc
    4. Select an arc of 360° for this object by clicking one time on the 360° button.

    5. Pitch
    6. For this example, select the 1.0° resolution button by clicking on it. This will set the longitude spacing at 1°.

      Your scan settings should now look like this:

      [Scan Settings]
      Scan Settings
  8. Press the Accept button to set these parameters for the next scan.
  9. [Scan Settings]
    Scan Settings
  10. Scan the Object
  11. Initiate the scanning process by picking the Scan button at the bottom of the application window.

    [Scan Start]
    Scan Start

    At this point, the user may be presented with a dialog box requesting to perform a home routine. You should choose to home the platform by clicking Yes when prompted.

    [Home Dialog]
    Home the Scanner

    After a short period of time (<30 seconds) the object should appear in the display area of the program window.

    If the object looks like a series of lines, or a bunch of points, select one of the Shaded Surface rendering modes from the View menu.

  12. Display Navigation
  13. Moving the object around in the display area of the program can be a confusing matter for inexperienced users. There are relatively few rules regarding the movement of the subject, but they are presented as follows (These instructions assume the use of a three-button mouse):

    Left Mouse Button:This button controls the rotation of the subject around the X, Y, and Z axes. Careful placement of the cursor is important for accurate movements. The center point of the rotation will be placed at the point the cursor points to as you depress the left mouse button.
    Right Mouse Button:The right mouse button controls the panning motion in the up/down and left/right directions. Simply click anywhere in the window and drag to the left/right or up/down.
    Control + Right Mouse Button:This combination controls the zooming of the subject. To zoom in towards the subject, hold down the Control key, then click anywhere in the window with the right mouse button and drag the mouse down. To zoom away from the subject hold down the Control key and click anywhere in the window with the right mouse button and drag the mouse up.
  14. Save the File:
  15. We can now write out the scanned object into a file:

    1. Select Save As Ply... from the File menu. You will notice a Save Dialog Box appears.
    2. [File Save Dialog Box]
      File Save Dialog
    3. Navigate to the directory into which you would like to save the file. For the purposes of this tutorial, save the file into the '...\Program Files\Cyberware\CyScan\' folder.
    4. Supply a name for the file. For the purposes of this example, name the file hires.ply.
    5. Press the Save button to save the file.
    For Echo scan files, Cyberware has chosen not to use a three-character file extension for historical reasons. The CyScan file format will take the Inventor file extension, .iv. All PLY files should use the .ply file extension.
  16. Exit cyscan
  17. To complete the scanning process, select Exit from the File menu. You will notice that the program window will disappear from the desktop.

    Alternately, you may click the Exit button at the bottom of the main window.

    [Exit cyscan]
    Exit CyScan
  18. Convert the File
  19. To convert the file to any of a number of industry-standard file formats, use the PlyTool program. Please see the PlyTool Tutorial for more information.

    For those users who do not have access to PlyTool, please refer to the output file formats listing.


The above steps cover the most basic use of the scanner. In this tutorial, you launched the program, opened a new scanning session, set the appropriate scan parameters, digitized the subject, displayed the object, and saved the data in the PLY file format.
