Abstract
Mobile mapping systems are commonly mounted on cars,
ships and robots. The data is directly
geo-referenced using GPS data and expensive IMU
(inertial measurement systems). Driven by the need
for flexible, indoor mapping systems we present an
inexpensive mobile mapping solution that can be
mounted on a backpack. It combines a horizontally
mounted 2D profiler with a constantly spinning 3D
laser scanner. The initial system featuring a
low-cost MEMS IMU was revealed and demonstrated at
MoLaS: Technology Workshop Mobile Laser Scanning at
Fraunhofer IPM in Freiburg in November 2014. In this
paper, we present an IMU-free solution.
