Minnesota 3D
Scanning Project
In this project we employ a state-of-the-art 3D scanner to
scan real world (urban) environments and then develop algorithms
and software to register, segment, and render the scanned data.
The scanner we use is the LMS-Z360
3D Imaging Sensor from Riegl USA,
Inc.
This scanner is capable of scanning large outdoor environments
(ranging up to 200m). The scanner offers high precision (1cm
precision within a range of 200m), large field of view (90° x
360°), and high speed (18 000 pts/sec).
Applications: There are a wide range of application for
the combined hardware and software system: archaeological site
and landmark structure preservation, urban planning, architecture
design, and entertainments, etc.
Scanning Downtown Minneapolis In Summer 2006, we scanned a
portion of downtown Minneapolis around the Walker Art area. Then
freshmen Mike Kaeding and Pat Weygand did the scanning by driving
a van around mounted with the scanner. In-between the scanning,
they registered the scans together using our in-house tool. Mike,
Pat, and Nathan Gossett (PhD student) did an interview with the
WCCO on the project and was aired on 6/12/06. video here
