Welcoming a versatile and simple solution for 3D vision applications

Powerful projector + high resolution = greater level of detail

Wide field-of-view, captures large volumes in real time
Equipped with two high-resolution 1.3 megapixel CMOS sensors, the new Ensenso N20 GigE 3D camera provides a wider field of view and can capture larger volumes up to working distances of 3 meters. A more powerful projector with blue LED together with the high resolution of the sensors, provides a much greater level of detail and precise 3D data, with even difficult surfaces.

The GigE interface also allows cable lengths of up to 100 meters and, because the camera is "powered over Ethernet" (PoE), it is simpler and costs less to integrate to your system.

Use straight-out-of-the-box
The N20 is pre-calibrated and comes ready for immediate use and provides the user with metric 3D data "out of the box" and is available with different focal lengths (see below).

How this 3D stereo camera works
Each individual shot delivers a virtually flawless 3D image.

The camera operates according to the "projected texture stereo vision" principle where the integrated projector casts a very dense random point pattern onto the object to be captured, enhancing structures that are not visible or are only faintly visible and eliminating the need to find textures on the object being imaged.

In multi-camera applications the data from two or more inter-connected 3D cameras is combined into one 3D dataset automatically. Thus, an object can be captured from several sides. In addition, the working area and the resulting precision can be scaled to meet virtually any requirement by adjusting the number of cameras installed.

Measuring only 175 x 50 x 50 mm, the stereo camera is comparatively small, despite the integrated projector and the two CMOS sensors, takes up little space. Its robust aluminum housing and screw-in connections also make it very suitable for industrial use.

Software
The N20 comes with its own SDK and will interface to MVTec's HALCON image processing library as well as other 3D image processing libraries.

The Ensenso software has been optimized particularly for robot vision applications as well as for multi-camera applications. The data from two or more inter-connected 3D cameras is combined into one 3D data set automatically enabling an object to be captured from several sides. In addition, the working area, and the resulting precision, can be scaled to meet virtually any requirement by adjusting the number of cameras installed.

The software also allows easy integration with uEye industrial cameras with USB 2.0, USB 3.0, or GigE connections for capturing additional colour information or barcodes as well as 3D images.

One of the features of the SDK includes software-controlled subsampling and binning, enabling extremely flexible data and frame rates, e.g. up to 80 Hz; and hand-eye calibration, which makes it easier to integrate the camera in bin-picking applications.
