Multipix Imaging introduces the compact Ensenso N10 stereo 3D camera with universal serial bus (USB) interface. The camera works according to a new procedure, called “projected texture stereo vision,” and is fitted with two global shutter complementary metal oxide semiconductor (CMOS) sensors and a pattern projector, which projects a random dot pattern onto the object to be captured. The key advantage of the pattern is that it also works in multi-camera operation and is 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 10 minutes out of the box. Using the free software interface supplied, you can integrate the camera into your own application programs.

When working with multiple cameras, the software package also enables you to output a single 3D point cloud containing the data of all the cameras used. Using multiple cameras at the same time enables you to capture a scene synchronously from different sides, thus reducing shadowing effects and extending the field of view. The Ensenso N10 stereo 3D camera is designed for working distances of 280 millimetres (mm) to 1400mm 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 (fps).

Using the texture stereo vision procedure, the projector launches 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 (IR) light and is highly resistant to external light influences.

The sturdy aluminium housing measures a mere 150mm × 45mm × 45mm. The camera’s suitability for industrial applications is underlined by a lockable 3-pin M8 sensor/actuator connector with general purpose input/output (GPIO) for 12 volt (V) to 24V hardware trigger input and output as well as a lockable USB cable. The Ensenso N10 3D camera is suitable for a wide range of applications. However, applications in the areas of medical engineering, robotics and gripping technology, logistics, completeness checking and rapid volume measurement, as well as measurement technology and safety engineering, benefit particularly. With a refresh rate of 30fps, the Ensenso N10 can be used completely in-line and is, therefore, suitable for use in 100% inspections.

The NxLib Software Development Kit (SDK), which comes with the Ensenso, includes an MVTec HALCON interface that allows the camera data to "grab" into HALCON for further 3D analysis.
