Error
The SD card of the scanner could not be accessed.
Solution
Make sure that the SD card is inserted and that it is not write-protected and
has sufficient free space left (approximately 330MB).
Error
Communication with the scanner failed.
Solution
Make sure that the WLAN connection to the scanner is stable.
If this error appears when connecting to the scanner or applying the
compensation parameters, try to repeat the corresponding step.
8.4 Scan Groups
A scan group is one scan grouped together with one or more detail scans that
were taken using the scan group function. The scanner records fixed spatial
relationships among all the scans in the group. The scans in a scan group are
represented as a group in SCENE.
Use scan groups to
reduce scanning
time
To keep scanning time to a minimum, you usually select the lowest resolution
that will capture the physical details you need for your scan project. But this
resolution may not scan registration targets with the detail you need for
accurate registration. Rather than making the entire scan with a higher
resolution, you can use a scan group to first make one complete, 360° scan
(referred to here as the primary scan), then make several higher-resolution
detail scans of the targets that are visible in the first scan. This reduces the
total time needed to scan the area, while still getting high-quality scans of the
targets to ensure that registration is accurate.
About detail scans Detail scans are different from ordinary scans. They contain no high-precision
inclinometer and compass data, and are generally useful only in the context of
their scan group.
