Flexible shape measuring system for mid-sized objects
Many applications, such as medical engineering, demand the fast scanning of an object's shape. The CAM3D optical sensor enables complete surface measurement of an object in under a second. The generated point clouds are available immediately after measurement and can be computer processed to create a triangle mesh within a few minutes.
Fast evaluation and 3D display of data with easy-to-use software open up numerous opportunities for the user.
CAM3D is used for:
- Non-contact measurement of works of art
- Reverse engineering
- Industrial shape and positioning inspection
The following objects were first digitized using CAM3D, then the SLIM3D reverse engineering software was used to process and display the data as triangle meshes
Mesh of a human head, reconstructed from 45 measurements (from the real-life subject) with a measurement accuracy of 130 µm.
Mesh of a bronze sculpture by Franz Marc (Moritzburg National Gallery, Halle / Saxony-Anhalt Regional Studies Museum), reconstructed from 32 measurements with a measurement accuracy of 120 µm.

3D-Shape GmbH also provides 3D measurement services using the CAM3D measuring system.
CAM3D is an optical sensor based on coded illumination. Measurement is based on a patented process that involves illuminating the surface of the measured object with a fringe pattern. A camera observes the illuminated object from the side. The surface shape of the object is calculated according to the resulting displacement of the fringes.
