3D SHAPE GmbH - flexible shape measuring system

Many applications, such as medical engineering, demand the fast scanning of an object's shape. The CAM^3D 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.

CAM^3D is used for:
- Non-contact measurement of works of art
- Reverse engineering
- Industrial shape and positioning inspection

Measurement Examples

The following objects were first digitized using CAM^3D, then the SLIM^3D 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.

Textued 3D mesh of a potato chip bag, aquired with CAM^3D.

3D-Shape GmbH also provides 3D measurement services using the CAM^3D measuring system.

Measurement Principle

CAM^3D 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.
