Inadequate Exposure and/or Missing Points
Objects that have stark, contrasting colors necessitate different camera exposures
and might prove difficult during automatic “tuning.” Tuning is the process by which
the software determines the best camera exposure for capturing the color of the
object and the best exposure for capturing where the laser is hitting the object.
Repositioning the object on the turntable so the camera can tune to a different side
of the object might resolve this problem. A second option is to utilize the “High
Contrast Scanning” function under the Advanced Scanning menu.
Some objects that have intertwined high contrasting colors can’t be scanned with
one exposure. Dual exposure will yield impressively better results. Spending a few
extra minutes manually setting the exposures for objects with stark color contrasts
will likely lead to complete point clouds and watertight meshes. See High Contrast
Scanning (p. ) for more details.
In the following example, an attempt to scan an apple with a very light spot near the
stem proved very difficult using automatic tuning.
Bad Exposure
Point Cloud PLY File Format
Note the area of the apple where the color was
light wasn’t captured at all.
Bad Exposure Final Outcome
Meshed OBJ File Format
Note where the missing data led to the apple
looking like a bite was taken from it.
Proper Exposure
Point Cloud PLY File Format
Note the light spot on the apple has been captured.
Proper Exposure Final Outcome
Meshed OBJ File Format
Final mesh has better color and more accurate
surface detail overall.
