High Contrast Scanning (Regular Scan); How Do I Identify High Contrast Objects; Setting High Contrast Laser Exposures - Matter and Form V2 User Manual

When more than one exposure gives good results,
choose the lowest value, as this reduces total
scanning time and the capturing of noise points
from the scan bed.
High Contrast Scanning (Regular scan)
High Contrast Scanning is a method for capturing the best
data possible when scanning objects with more than one
color, particularly contrasting colors, like black and white.
High contrast scanning allows for improved laser detection
by tuning two different exposures, one for each contrasting
color.
Click the High-Contrast checkbox in the Geometry Settings
toolbox to turn on high-contrast scanning.
How Do I Identify High Contrast Objects?
Use high contrast If your object has
colors from both of these
categories:
1) Blue, Purple, Dark Green, Black
2) Yellow, Orange, Red, Grey, White
(and pastel colors)
Try High-Contrast, if the green visualization overlay for the
lasers in the Geometry camera feed does not achieve a
complete line when adjusting the Geometry Settings slider.

Setting High Contrast Laser Exposures
To set a different exposure for each colour, first adjust the top
Geometry Settings slider for Exposure 1 to capture clean
laser lines on the light areas of the object.
Some models cannot be
scanned with only one laser
exposure due to their high
contrast colors: grey and
white both contrast with
black.
Here you can see the laser
lines when a darker
exposure is selected. One
color shows well, but the
other doesn't.
Here you can see the laser
line shows up well on the
black, but is spotty on the
white.
