Apparatus For Taking Measurements In Access Manholes
US Patent:
7703343, Apr 27, 2010
Filed:
Jan 29, 2008
Appl. No.:
12/011798
Inventors:
Matthew E. Rodgers - Sacramento CA, US
International Classification:
G01L 3/00
US Classification:
7386208
Abstract:
An apparatus for measuring three-dimensional spatial locations of pipes and other features in manholes and similar structures. A laser distance meter or other electronic distance measuring device is supported centrally in the manhole opening by a pivot assembly that permits the device to both rotate in the horizontal plane and pivot in the vertical plane. Electronic angle sensors record the distance and orientation of the laser distance meter at each measurement point, from which the three-dimensional spatial location of the pipe or other feature is then calculated.
