Structured light

3D scanning of objects of art

An active lighting using fringe projection provides a dense 3D point cloud, representing the surface of the part.
Some characteristics of the scanning process:

• Scanned surface
• Point density: up to 4 million from mm² to m² point in a frame
• Duration of acquisition: 5 to 15 seconds

From the point cloud, many applications are possible:

• measurement of dimensional deviations from a CAD file
• identification of a part type · control of compliance (presence accessories, inserts, ...)
• direct machining using the point cloud
• surface reconstruction and reverse engineering
• dimensional control

Surface reconstruction is to calculate CAD surface-type (Beziers, NURBS) based on the scanned point cloud. This provides a CAD file (IGES) of a part or an object that has not been defined initially using a CAD tool.

Technology :

HOLO3 has a comprehensive know-how of this technology incorporating both the material aspect and the software side and can offer companies a real transfer of technology, with license agreement and complete training.
