Any window can be moved between monitor and projector back and forth. So in case the main DAVID window is displayed on the projector, please grab its title bar with the mouse and drag it sideways onto the monitor. -
Page 9: Setup And Calibration Of The Scanner
4. Setup and Calibration of the Scanner An advantage of the modular design of the SLS-2 is that it can be adjusted to scan a wide range of objects sizes. Therefore, a calibration (measurement of the scanner hardware in the software) is necessary so that the software can then obtain precise and undistorted 3D data at the correct scale. - Page 10 Figure 4.2: Adjusting rings (A) aperture and (B) focus, Figure 4.3: Setup of the object and arrangement of the projector (C) fixing screws and camera 9 Camera brightness/aperture: The ”Projector Brightness“ slider in the software should be set to maximum. You should only reduce it if a clean modulation is not possible in the following.

10 Fasten all screws (projector, camera and camera slide), so that nothing can be displaced from now on. The camera lens dials can be fixed with their locking screws (C). The scanner is now optimized for your ob- ject (size of the scanning area, working distance, brightness of the object) and must be calibrated like this. 4.2. - Page 12 Figure 4.11: Ideal live camera image for calibration the scanner as a whole, and you can close the DAVID software and restart it without losing the calibration. You can also change the value of ”Projector Brightness“ to adjust the brightness (red sine curves) to the respective object to be scanned.

5. 3D Scanning 5.1. Menu ”Structured Light“: Place the scanner and the object in front of each other, at the same distance as during setup and calibration. With a wrong working distance, the camera image and projected stripes would be blurred. If necessary, correct the distance between object and scanner, but by no means change the focus of camera or projector. - Page 14 Figure 5.3: Display of the scan result in 3D If you activate ”Auto. Grab Texture“, a color texture will be recorded with each scan. If the texture is too bright or too dark, you can adjust its settings in the ”Texturing“ menu (see next sub-chapter). You can toggle the visibility of the texture in the 3D view using the appropriate button under ”Visibility“.

White Balancing: Whenever you change the texture settings, you should re-perform the white balancing. That means DAVID calibrates color transmission characteristics of the entire system (projector, camera), in order to be able to measure the colors of the object correctly. For white balancing, the camera image must show exclusively a large white object (such as the glass calibration panels or a white wall). -
Page 16: Alignment And Fusion Of Multiple Scans
In the following, we will describe the general case how to fuse variously positioned scans. Notes on special cases and more detailed information can be found on http://www.david-3d.com/manual Figure 6.1: Menu ”Shape Fusion“ 6.2. Alignment of Multiple Scans In general, the individual scans are collected via the ”Add to List“ button during scanning. You can import more scans (OBJ) into the List of Scans - either by drag and drop from the Explorer, or using the ”+“... - Page 17 DAVID offers several alignment modes. First, start with the alignment mode ”Free“, which allows you to align arbitrarily positioned scans one-on-one. In order for the automatic mode to align two scans suc- cessfully, the two scans must have a unique region of overlap in common, which must not be too small.

If the automatic alignment finds false solutions, you should activate ”Contact Pair Selection“ . Then you can help DAVID by clicking on distinctive points that are to be aligned with each other (e.g., tip of the nose). Relevant here is the area within the red circle at the mouse pointer. If you would like to define the contact pair points very precisely, zoom up close with the mouse wheel before you click. -

8.2. Problems with Alignment / Fusion Problem Cause / Solutions Shape Fusion: The scans are aligned DAVID aligns the scans such that the overlapping areas are maximized. That completely wrong maybe causes wrong solutions if there are more than one matching overlap- ping areas. -
