Getting a grip on 3D imaging

Multipix Imaging has introduced the new Ensenso N10 stereo 3D camera with USB. The camera works according to a new procedure called ‘projected texture stereo vision’ and is fitted with two global shutter 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 well suited 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, you can also integrate the camera easily 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 280mm to 1,400mm and for variable fields of view. 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. The Ensenso N10 captures nearly all surfaces within the field of vision and is highly resistant to external light influences.

The aluminium housing measures a 150 x 45 x 45mm. The camera also includes a lockable 3-pin M8 sensor/actuator connector with GPIOs for 12-24V hardware trigger input and output as well as a lockable USB cable. The camera is suited to a range of applications and with a refresh rate of 30 frames per second, it can be used inline and is therefore ideal for use in 100% inspections.
