N20 3D stereo camera Back to iDS Cameras Back to 3D Cameras Back to GigE Cameras |
 |
Real-time 3D imaging; wide
field-of-view; captures large volumes
Equipped with two high-resolution 1.3 megapixel CMOS sensors, the new
Ensenso N20 GigE 3D camera series provides a wider field-of-view
and can capture larger volumes up to working distances of 3 meters.
A more powerful projector with blue LEDs together together with the high
resolution of the sensors, provides a much greater level of detail and
precise 3D data, even with difficult surfaces.
The GigE interface also allows cable lengths of up to 100 meters
and, because the camera is "powered over Ethernet"
(PoE), costs are reduced as there is no need for an additional
cable for the power supply.
The Ensenso N20 is pre-calibrated and comes ready for immediate
use and provides the user with metric 3D data "out of the
box".
How this 3D stereo camera works
The camera operates according to the "projected texture stereo vision"
principle where the integrated projector casts a random point pattern
onto the object to be captured, enhancing structures that are not visible
or are only faintly visible. Each individual shot delivers a virtually
flawless 3D image.
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. In addition, the working
area, and the resulting precision, can be scaled to meet virtually any
requirements 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, taking up little space. Its robust aluminum housing and screw-in connections also make it very suitable for industrial use.
Software
The Ensenso N20 comes interfaced to the MVTec HALCON image processing
library and an extensive Software Development Kit (SDK).
The Ensenso software has been optimized particularly for robot vision applications as well as for multi-camera applications and 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.
