PolyWorks’ capabilities
are tailored to the needs of surveyors in the fields of architecture,
building site survey, and city modelling, allowing:
| • |
Accurate scan alignment using
the geometrical shape of the scene, with no need for field targets. |
| • |
Easy geo-referencing of
the entire point cloud using a minimum of three known points
in the real-world coordinate system, or three known scanner
positions. |
| • |
Quick extraction of multiple
“as-built dimensions”, such as distances, volume,
angles, radii, and more. |
| • |
Automatic extraction of feature lines, such as
building edges and footprints, and other architectural details, such as doors
and windows.
|
| • |
Automatic creation of 3D
polygonal models, using original color and/or intensity information,
for highly detailed visualization applications. |

PolyWorks combines point matching and a powerful best-fit
alignment method to align scans using the geometrical shape of the scene. |
| • |
No field targets are required for the alignment. However, markers
can be used in the scene to validate the alignment results. |

PolyWorks geo-references the point cloud by adjusting its
coordinates using a minimum of three known points in the real-world coordinate
system (obtained using GPS, Total Station, etc). |
| • |
PolyWorks can also geo-reference the point cloud using a minimum
of three known scanner positions. |
|
 |
| |
In this example, the scene
is geo-referenced by matching three target points with three
known real-world coordinates. |
|
 |
 |
Various measurements
can be taken directly on point clouds or on polygonal models,
such as:
| • |
Distances (horizontal,
vertical, slope) |
| • |
Angles (bearing, azimuth) |
| • |
Radii |
| • |
Volumes |
|
|
 |
PolyWorks offers automatic and
interactive tools to extract valuable features directly on the point
cloud, such as:
 |
 |
| Feature lines |
Cross-sections (e.g. horizontal, profiles) |
 |
 |
Sharp edges
Features which can also be extracted:
| • |
Step edges (e.g. curbs and gutters) |
| • |
Electrical cables |
| • |
Pipe center lines |
| • |
Geometrical primitives (cylinders, planes, vectors, etc.) |
NB: If needed, all features can also be directly extracted on polygonal models.
|
Cross-sections (footprint)

 |
Export of Extracted Features
| • |
All features extracted in PolyWorks can be exported to DXF and
IGES |
| • |
Extracted features can also be directly imported into
MicroStation V7 and V8 |
| • |
User-defined Feature Codes and Layer Names can be used in the
export process |
| • |
PolyWorks also generates reports in Excel, Word, and HTML
|
|
|
 |
| • |
Surveyors can visualize colored point clouds and colored
polygonal models of scanned objects, and make them available for inventory
databases and public libraries. |
| • |
Surveyors can easily create 3D animated videos (in AVI), or
directly visualize their polygonal models with PolyWorks’ free viewer. |
