Introduction Measurement Examples
Measurement Principle

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

Measurement Examples

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

3D-Shape GmbH also provides 3D measurement services using the CAM3D measuring system.

Measurement Principle

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.
