<strong>CAM</strong><br />
<strong>information</strong><br />
<strong>Fringe</strong> <strong>projection</strong> <strong>sensor</strong><br />
<strong>3D</strong><br />
<strong>CAM</strong> is an optical <strong>3D</strong> <strong>sensor</strong> for fast and highprecision<br />
object shape scanning, whatever the nature<br />
and size of the object.<br />
Various modifications enable a wide range of applications.<br />
Fast evaluation and <strong>3D</strong> display of data with easy-to-use<br />
software open up numerous opportunities for the user.<br />
<strong>3D</strong><br />
<strong>CAM</strong> is used for:<br />
<br />
<br />
<br />
<br />
<br />
Measuring human faces (“<strong>3D</strong> portraits”)<br />
Non-contacting measurement of works of art<br />
Measuring in orthopedics and other medical fields<br />
Reverse engineering<br />
Industrial shape and positioning inspection<br />
Reverse Engineering<br />
Medical Technology<br />
Preservation of<br />
Historical Buildings<br />
Mold Making<br />

<strong>CAM</strong><br />
Measurement Principle<br />
Creating a <strong>3D</strong> portrait<br />
<strong>3D</strong><br />
<strong>CAM</strong> is an optical <strong>sensor</strong> based on coded illumination.<br />
Measurement is based on a patented process that involves<br />
illuminating the surface of the measured object with a fringe<br />
pattern. A camera observes the illuminated object from the<br />
side. The surface shape of the object is calculated according<br />
to the resulting displacement of the fringes.<br />
The system's high flexibility and extremely low scanning<br />
time mean that objects can be fully measured in<br />
just a few minutes.<br />

<strong>3D</strong><br />
<strong>CAM</strong> D<br />
One projector with two cameras for simultaneous<br />
scanning of two views (e.g. for <strong>3D</strong> portraits)<br />
<strong>3D</strong><br />
<strong>CAM</strong> DF<br />
Device with two switchable measurement field sizes<br />
Mesh of a human head,<br />
reconstructed from<br />
45 measurements<br />
(from the real-life subject)<br />
with a measurement<br />
accuracy of 130 µm.<br />
All devices are factory calibrated. Calibration equipment is<br />
available as an optional extra.<br />
Measurement Examples<br />
<strong>3D</strong><br />
The following objects were digitized using <strong>CAM</strong>, then the<br />
<strong>3D</strong><br />
SLIM reverse engineering software was used to process<br />
and display the data as triangle meshes.<br />
Mesh of a bronze<br />
sculpture by<br />
Franz Marc<br />
(Moritzburg National<br />
Gallery, Halle / Saxony-Anhalt<br />
Regional Studies Museum), reconstructed from<br />
32 measurements with a measurement accuracy of 120 µm.<br />
Mesh of the Trumpeting Angel<br />
in Bamberg cathedral, reconstructed<br />
from 200 measurements with a<br />
measurement accuracy of 140 µm.<br />
Mesh of a<br />
CAD object (size<br />
approx. 20 cm), reconstructed<br />
from 38 measurements with an<br />
accuracy varying from 10 to 100 µm.<br />
<strong>3D</strong>-SHAPE <strong>GmbH</strong> also provides <strong>3D</strong> measurement<br />
<strong>3D</strong><br />
