SENSE SCANNING TIPS AND TRICKS
Many practices that ensure good photography also apply to scanning . Use the following tips to get the most from your scanning
experience:
LIGHTING
•
Different lighting conditions can affect the quality of a scan . The Sense for Intel RealSense 3D scanning application is designed for
indoor use, and will work less than optimally in direct sunlight .
•
Position your subject in a way that will cause as little shadow as possible . You may need to add additional light to reduce shadows .
•
You’ll get the best results if the light shines with equal intensity over the subject being scanned . Areas that are less illuminated
might show up too dark in the scan, and areas that are over-illuminated might show inaccurate colors .
•
If you scan in darkness, the scanner will capture geometry but not color .
POSITIONING
•
Position your subject so that you have 360° clearance around it .
•
In preview mode, make sure that the whole object you want to scan shows inside the green box on the screen . This helps ensure
that you capture the entire object while scanning .
•
Keep the scanner within its optimal distance range of the subject, which is approximately 0.45m - 2m (18” - 6.5 ft.).
MOTION
•
Multiple passes on the object are allowed. If there are gaps in the scanned data after a single pass, continue scanning to try to fill
the gaps .
•
If the 3D view turns white as you’re scanning, it is because the object being scanned is too close to the scanner . To correct the
view, move the object out to at least the minimal defined distance of 0.5m (20 inches).
GENERAL
•
Before scanning a small object or one without a lot of distinct features (such as a standard coffee mug), add some items around the
object . This will help the scanner maintain tracking by giving it more to lock on to .
