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.
