Want to make sure your 3D scans turn out as crisp as possible? Make sure to follow these five tips!
Set up your projector properly
The projector should appear as Monitor 2 in the Screen Resolution window. The projector is an active monitor on your PC – opening other windows on, or moving windows to, Monitor 2 will interfere with scanning. Monitor 2 should be set to these parameters:
– Resolution: 800 x 600, minimum
– Orientation: Landscape
– Multiple Displays: Extend these displays
– Refresh Rate: 60 Hz
– Monitor 2 must be to the right of Monitor 1, with the tops of the two aligned
Check your display power settings
Don’t let your computer fall asleep on the job. Set your display power settings to “Never”, or pick a timeout setting that is more than sufficient to complete your scan. (Most scans take less than 3 minutes.)
Remember to calibrate
Calibrating your scanner ensures that the software knows the relative positions of the cameras to the scanner bed. You will need to calibrate when first setting up your scan, and also if the scanner head or turntable is moved.You may need to re-calibrate if the meshing is not succeeding, or if the object does not appear correctly in the image of the turntable on your monitor.
Control ambient lighting
Ambient light levels affect your scan. Generally, low light levels are good (for texture scans, very low light levels), but in some cases a little more ambient light can make a big difference. Experiment with the amount of light, and the position of the light source, until you get the best results.
A word about black
This scanning technology is based on the refection of light. Black is a color that absorbs light. If your object, or a portion of it, is black you may be able to improve your scan by brushing the black surface with a light dusting of baby powder (talc) or cornstarch. If you need to prop up your item, or stabilize it in some way, black supports are the way to go – they will not appear in your scan.
