Winch
• Depth correction of the cable
(elongation by system weight,
winch correcting factor)
IMU-data
• Determination of movements
(rotation and oscillation)
Scan data
• Unwrapping of measurement
values
• Corrected by depth and rotation
• Correction of oscillation is under
progress
• Conversion into 3D-model
• Several data evaluation and
visualization options
