Assignee:
Arc Second, Inc. - Dulles VA
International Classification:
G01B 1126
US Classification:
3561414, 356 408
Abstract:
An improved low cost theodolite position measurement system and process which is particularly useful in enabling a single operator to conveniently set up the system and calculate elevation (el) and azimuth (az) angle data. Only a single optical transmitter is positioned within a predetermined workspace thus significantly decreasing equipment costs and setup time. The single transmitter is positioned and leveled at a predetermined point in the workspace. In operation the single rotatably mounted transmitter head illuminates the workspace volume with a pair of spaced apart precalibrated fan beams which sweep the space and a periodically emitted reference strobe pulse. At least one optical receiver is selectively positionable within said workspace so that during each revolution of said single transmitter head said receiver receives a first position strike and a second position strike of said fan beams. To determine elevation angle data, tracker logic means responsive to said receiver determines a first tie interval separation between receiving said first position strike and said second position strike and calculation means for converting said first time separation interval into an elevation angle data. To determine an azimuth angle data said receiver receives a strobe pulse and a fan beam position strike, both of which are repeatedly transmitted with a known periodicity, determining a measure of time separation related to the strobe pulse and the position strike, and converting the measure of time separation into the azimuth angle data utilizing the known periodicity.

International Classification:
G01C 103
G01C 300
G01C 500
G01C 300
G01C 500
US Classification:
356 1
Abstract:
A spatial positioning apparatus providing three-dimensional position information and methods to utilize the position information for improved surveying, construction layout, equipment operations, manufacturing control and autonomous vehicle control is disclosed. The spatial positioning apparatus includes at least three, preferably four, fixed referent stations. A minimum of two, preferably three, of the fixed stations sweeps a spread laser beam horizontally across the site of interest. The remaining fixed station sweeps a spread beam vertically across the site of interest. A strobe signal is emitted from each fixed station when the rotation mechanism actuates a rotation datum. The spatial positioning apparatus also includes one or more portable position sensors. The portable position sensor includes a light sensitive detector, a computer, and a display. The x, y, z coordinates of the portable position sensor are obtained through a triangulation technique based on time marks received from each spread laser beam from the fixed stations and the rotation datum received from the strobe of each fixed station.

52949702, Mar 15, 1994
Filed:
Sep 6, 1991

International Classification:
G01B 1126
G01C 300
G01C 300
US Classification:
356152
Abstract:
A spatial positioning system includes fixed referent stations which emit rotating, divergent laser beams and a portable reflector. Each fixed station also includes a detector and a processor. The portable reflector may include retroreflectors or transponders. When the rotation of the laser beam is such that it is in line with a portable reflector, the transmitted laser beam is reflected off the portable reflector and received at the fixed receiver. For any point which is crossed by the fanned laser beams of a fixed station, a horizontal angle can be determined. Once these horizontal angles are known for three fixed stations, the point of intersection of three planes, and thus the three-dimensional position of the point, is determined.

US Classification:
356 1
Abstract:
A spatial positioning and measurement system provides three-dimensional position and/or measurement information of an object using one or more fixed referent station systems, and one or more portable position sensor systems. Each fixed station produces at least one primary laser beam which is rotated at a constant angular velocity about a vertical axis. The primary laser beam has a predetermined angle of divergence or angle of spread which is inclined at a predetermined angle from the vertical axis. Each fixed station also preferably includes at least one reflective surface for generating a secondary laser beam. The portable position sensor includes a light sensitive detector, computer, and a display. The light sensitive detector can be formed of at least one "axicon" which directs incoming light to a photosensitive detector. The photosensitive detector generates an electrical pulse when struck by crossing laser beam and sends this pulse to the computer.
