Scan An Object Using Multiple Scanners With Target Markers - 3D Systems Geomagic Capture Series User Manual

SCAN AN OBJECT USING MULTIPLE SCANNERS WITH TARGET MARKERS

By connecting multiple Geomagic Capture Series 3D scanners to a single PC, you can automate the 3D scanning process. The
Geomagic Capture generates complete 3D scan data without any motion control and helps you to reduce scanning time.
Note: It is not recommended that you use scanner setup mixed with different type of the Geomagic Capture Series 3D
scanners.
1. Place target markers on either the partifact or another object.
You can also put the target markers on a surface the part rests on, such as a turntable in order to use these features during
alignment.
Note: The placement of target markers should be in an unique pattern, similar to stellar constellations, to make it easy
for the scanner to identify target markers. If you place the target markers in a regular pattern (such as a grid), the
scanner may have difficulty matching target markers and fail to align scans. Please ensure the target markers are placed
so cameras can see them even though the part is moved.
Note: To align two scans, at least four target markers must be matched between the two scans. This means that
regardless of which strategy you use for scanning, you must use enough target markers so that there are always at least
four target markers visible from cameras in connected scanners during the scanning.
2. Place the part on the stable plate and position the scanners around the part. For more information, see
3. Enter the scanning command in your Geomagic application to connect a scanner.
4. After the Geomagic Capture application is initiated, check if the scanner has been connected properly.
5. Set the center of projected pattern close to the camera focus.
The red cross-hairs shows the camera focus and the gray grid on the object shows the projected pattern.
6. Adjust the Exposure setting for the first scanner to get an ideal scan.
7. Adjust the Exposure setting for the other scanners.
