  • Page 6 The Windows Taskbar and most desktop icons will be shown only on the monitor. All windows can be moved from monitor to projector, and vice versa. If the DAVID main window is shown on your projector, grab its title bar with the mouse and move it over to your monitor.
  • Page 7 Calibration of the Scanner Calibration of the Scanner One advantage of the SLS-1's modular setup is that its size can be adjusted to very different object sizes. Therefore, calibration (measurement of the current hardware setup in the DAVID software) is required, allowing the software to obtain undistorted 3D data at the correct scale.
  • Page 8 6. Aim the camera so that it can see the projected pattern on the object. Then fix the ball joint. 7. The Exposure Time should be set to 1/60s, otherwise the camera image might flicker or pulse when looking at the projection. 8.

  • Page 12 • If you check the “Auto. grab texture” option, DAVID will record a texture with each scan. If the texture is too bright or too dark, you can adjust the texture settings in the Texturing menu (see below). • With your mouse, you can rotate, move and zoom the 3D view.
  • Page 13 • DAVID offers several alignment modes. In general you should start with the “Free” mode, which aligns one scan to one other with each step. In order for the automatic mode to find the correct alignment, the scans have to overlap sufficiently, i.e.
  • Page 14 • Hint: All scan movements can be undone separately with the “Undo” button • Hint: You can save your single scans at any time. They will be saved in their current position and rotation in space, so you won't have to align them again. •...
