July 24, 2014 - IDS Imaging Development System announces Ensenso N20 stereo camera with active texture projection for 3D vision applications. The camera is equipped with a Gigabit Ethernet interface and two high-resolution 1.3 megapixel global shutter sensors. The N20 provides a wide field of view making it suitable for capturing larger volumes and for working distances of up to 3 meters. A powerful projector with blue LEDs, coupled with the high resolution of the sensors, achieves a greater level of detail and delivers precise 3D data even with difficult surfaces. The GigE interface also permits cable lengths of up to 100 meters. Plus, because the camera is "powered over Ethernet" (PoE), there is no need for an additional cable to supply power.
The Ensenso N20 employs the "projected texture stereo vision" principle. This works by an integrated projector casting a random point pattern onto the object to be captured, enhancing structures that are not or only faintly visible. As a result, even a single shot delivers a virtually flawless 3D image. Despite the integrated projector and its two CMOS sensors, the Ensenso N20 measures only 175 x 50 x 50 mm, so it takes up little space, while its robust aluminum housing and screw-in connections make it extremely suitable for industrial use. The N20 is available with different focal lengths. A camera selector on the IDS website helps the user to choose the right model. IDS also provides comprehensive system consulting on how to use the camera and software. The Ensenso N20 is pre-calibrated and comes ready for immediate use. The user is provided with metric 3D data "out of the box". Software Included The Ensenso N20 comes with an interface to the MVTec HALCON image processing library and an extensive Software Development Kit (SDK), which is identical for the GigE and USB model. The 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 can be 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 requirements by adjusting the number of cameras installed. The Ensenso software also allows to easily integrate IDS industrial cameras with USB 2.0, USB 3.0, or GigE connections to capture addition color information. Other important features of the SDK include software-controlled subsampling and binning, which allows extremely flexible data and frame rates up to 80 Hz.
