NEW PRODUCT PRESS RELEASE

German camera manufacturer VRmagic (Mannheim, Germany) presents a 3-D area sensor based on digital light stripe projection that supplies ready-calculated 3-D data records for industrial image processing. The AreaScan3D sensor outputs the recorded 3-D data to the evaluation computer via the Industrial Ethernet interface. The data is output directly as a point cloud or a grayscale-coded range map. The 3-D sensor is addressed via a GenICam transport layer (GenTL). It is therefore compatible with all image processing libraries and packages that can already communicate with a GenTL, such as Common Vision Blox or Halcon.

The AreaScan3D sensor can be integrated in industrial installations via the Industrial Ethernet interface. The sensor features a robust metal housing with IP65 protection, screw-type standard industrial connectors, a 24 V connection, an Ethernet interface as well as hardware and software triggers. AreaScan3D is available with measuring fields ranging from a few millimeters up to a square meter. It offers a guaranteed accuracy in the submicrometer to millimeter range, depending on the measuring field size. Stripe projection, image recording and generation of the point cloud are performed in an integrated manner based on an intelligent camera from VRmagic. The DLP pico projector from Texas Instruments and the camera are synchronized with a frequency of 60 Hz. Output of a complete 3D data record is currently possible with approximately 360,000 individual points per scan.

"With the AreaScan3D sensor we are offering plug and play technology, which can significantly optimize production processes for inspection tasks relating to position and completeness," says Oliver Menken, Sales Manager at VRmagic.

Compared with classic 2D image processing, optical 3D measurement with stripe light projection can offer more efficient and robust testing methods, particularly for inspection objects with low contrast or under varying lighting conditions. The material color also does not have any influence on measuring accuracy. The AreaScan3D sensor offers maximum external light stability through use of a color LED combined with a band-pass filter.

The company Stemmer Imaging will be exclusively responsible for distribution of AreaScan3D in Germany, France, Great Britain, Austria, and Switzerland as well South Korea and Taiwan.
