Whole Body Scan Tutorial

In this tutorial, you will complete a single scan of a human subject using a Cyberware Whole Body scanner and the DigiSize software. Further information on each of the commands and menu items is available in the DigiSize User Guide.

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

    [DigiSize]
    DigiSize Main Window
  3. If necessary, select a Whole Body scanner.
    1. Choose Scanner | Select Device....
    2. [DigiSize]
      DigiSize Main Window
    3. Double-click the WB scanner in the Choose a Scanner dialog.
    4. [Choose a Scanner Dialog]

  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.

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

    If the object looks like a series of lines, or a bunch of points, select the Smooth Shaded Surface rendering modes from the lower section of the main DigiSize window.

  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 the scanned object into a series of file Echo files, one Echo file for each scan head:

    1. Select Save As Echo... 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 files. For the purposes of this tutorial, save the files into the ...\DigiSize\guide\download\ folder.
    4. Supply a name for the file. For the purposes of this example, name the file hiresWB.
    5. You will be asked for permission to create a new folder, called hiresWB. This folder will be used to store the 4 scan files. Press the Yes button to save the files into the new folder.

      [Folder Creation Dialog]
      Folder Creation Dialog
      NOTE:
      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.

      When the save operation is complete, you should see a confirmation dialog similar to the illustration below:

      [File Save Dialog Box]
      File Save Confirmation
    6. Press the OK button to continue.
  16. Exit DigiSize
  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 DigiSize]
    Exit DigiSize
  18. Combine the four scans into a single PLY file
    1. Launch CyPie by double-clicking the cypie.exe executable, located in the ...\Program Files\headus\ folder.

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

Summary

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.
