UTSOA has a Konica Minolta Vivid 910 3D non-contact digitizing system. This scanner is located in the digital fabrication section of the technology lab in Sutton Hall basement near the lighting studio. It is free for use by all student in the school of architecture.
The Vivid 910 system is capable of scanning over 300,000 data points with very high accuracy in under one minute. The unit is also equipped with an automated rotary stage for 360 degree captures and will overlay captured geometry with textures captured from the camera lens of the unit.
Physical Scanning - Using the Konica Minolta Vivid 910 3D Scanner
- Power on the scanner.
- Press Any Key to continue.
- System Initializing.
- "Select" the Scan Option.
- Setup the scanner, model and lights.
- Put the light adjacent to the scanner, with both pointed at the model.
- Turn the light intensity and color to maximum.
- Make sure that all the surfaces you want to 'see' with the scanner are visible to BOTH the LASER window AND the Camera Lens.
- NOTES: You can use the foot pedals to adjust the height of the table. You can use the knobs on the tripod to adjust the height, angle and position of the scanner on the tripod.
- Once your model is in the viewer window and focused, "Release" to scan.
- Once the model is scanned, "Record" to save the scan to the the Memory Card. The 'grey scale' shows high-precision data collected, the areas that remain blue are either areas where no data or low-quality data are collected - for our purposes, low-quality data are usually OK.
- Screen while file is recording.
- If you are doing more scans return to step 5 (new object, new view of same object) or step 6 (new scan of same object view), else proceed to step 10.
- Power off the scanner and remove the "Memory Card" to transfer the scans to the adjacent computer.
Geomagic Workflow - Single Scan to Mesh
- Put the "Memory Card" into the CF Reader on the Workstation adjacent to the scanner.
- Login to the workstation with your UT EID.
- Copy scan files from the CF card to the Desktop.
- Launch the Geomagic Design X application from the Desktop.
- Find File and select option to "Run Mesh Buildup Wizard"
- Vivid Import Options: I recommend not using the 'high quality data' filter... it will often drop data you want - and it is usually easy to edit out the data you don't want
- Select the frame (named after file you imported), then click the 'right arrow' for 'next':
- Delete any data that is not part of your model (stands, table, backdrop, etc.) The grey boxes on the right explain how navigation and selection work. Then click the 'right arrow' for 'next'.
- Click the 'check mark' to run the wizard.
- Click 'Apply' to confirm running the wizard.
- Go to the 'Polygons' Menu and Run the Healing Wizard. Click the 'check mark' to run.
- Select the 'Fill Holes' option from the 'Polygons' Menu. Tell the wizard to ignore the 1 largest hole (that's your model's exterior boundary), it should auto-fill the rest of the holes when you select the 'check mark'.
- From the 'File' menu, select 'Export'.
- Select the frame (named after file you imported) as the entity to export.
- Give the file a name, usually you will pick a .STL file as the filetype to export (for CNC).
- You will also want to save the Geomagic version of your file: Menu->Save.
- Please return the "Memory Card" to the 3D Scanner when you are done.
Getting started with multi sided scanning:
NOTE: you want to scan as few scans as you can to collect data, arrange object for maximum surface overlap between scans (i.e. if shooting rectilinear object, do 4 90-degree scans with each one pointed at a corner - never on a flat side)
- In Geomagic Design X - Menu->Insert→Scanner Direct Control→Konica Minolta Vivid
- Go to 'Rotary Table' tab, Model is ZETA6104(Fast), Port is COM1, select 'connect' (you may have to do this more than once to get the green light)\
- Under 'single scan' you can use the Rotary setting (input desired rotation in degrees) - then click the move button to execute moves.
- Origin to start, do manual scan as above- then rotate by degrees, repeat until 360 captured
- Once multiple scans are in the memory card, bring them to the computer
- in a clean/new file, choose Menu->Insert→Import - select ALL of the .CDM files you just made - select import only
- go to the alignment tab and pick 'align between scan data' , select all of the frames from the left hand tree menu (use top select, shift, bottom select), local based on auto guess, hit checkmark
- Guesses - untested - polygon merge as next step, then healing wizard, (hole filling) and finally either mesh buildup wizard (watertight mesh option on) auto surface?
- The scanner works best with matte-white objects. Black, glossy, or transparent objects will have problems scanning or may not scan at all. Using corn starch, white spray paint, epsom salt spray (from the 3d print process), or 'spray developer' are ways that object can be treated to provide quality scanning.
- In order for a surface to be scanned it must be visible simultaneously to the optical lens (upper aperture) and the laser lens (lower aperture) on the 3D scanner.
- With the 'medium' lens the scanner and current setup the scanner is ready to scan objects ranging from about 3"-cubed to about 12"-cubed. (Using alternate lenses, this range can be extended down to 0.5"-cubed or up to 36"-cubed object volumes. For alternate lens installation see the computer lab service desk.)
