Image and Scan Problems

If the image looks distorted or incorrect, it could be one of a few issues.

The tripod is tipped over

Make sure the tripod is in place and hasn’t fallen over.

Uncalibrated Sonar

Repeat the calibration procedure outlined in the “Calibration” section of this

manual.

Spherical Scan process stopped before final point cloud creation

During a spherical scan process, the data for each horizontal sweep is stored in

a separate temporary file. When all horizontal scans are completed, the individual
scans are combined into a single file. If the system shuts down or aborts before
the software reaches the merge portion of the process, the operator can manually
merge the xyz files by copying all the data into a single xyz file using a text editor
such as Notepad.
