A random dot pattern is projected onto the object to be captured, which works in multi-camera operation and is also suitable for capturing unstructured surfaces. As the Ensenso N10 is factory calibrated, installation of the camera for 3D surface matching using the MVTec Halcon interface takes less than ten minutes out of the box. Using the free software interface supplied, users can also integrate the camera easily into their own application programs.

Working with multiple cameras, the software package enables engineers to output a single 3D point cloud containing the data of all the cameras used, capturing a scene synchronously from different sides, thus reducing shadowing effects and extending the field of view. The stereo 3D camera is designed for working distances of 300mm to 1400 mm and for variable fields of view. Unlike other 3D recording procedures, the camera can capture both static and moving objects at up to 30 frames per second.

Using the projected texture stereo vision procedure, the projector projects a static, high-contrast texture onto the scene and adds structures that are not visible or are only faintly visible on the object. Combined with the new “semi-global matching” image comparison algorithm, the Ensenso N10 captures nearly all surfaces within the field of vision. The system works with pulsed infrared light and is highly resistant to external light influences. The unit comes in a 150x45x45mm aluminium housing. For industrial applications, the camera comes with a lockable 3-pin M8 Pluscon connector with GPIOs for 12-24 V hardware trigger input and output as well as a lockable USB cable.
