The stereo 3D camera Ensenso N20 from IDS represents a solution for 3D image capture that is impressively precise, cost-efficient and fast. It successfully covers all bases in terms of the requirements that apply to robot vision applications. The industrial camera with GigE connection is the first of its kind on the market, integrating, as it does, not only two global shutter CMOS sensors with 1.3 MP resolution (1280 x 1024 pixels) and powerful software in a very compact housing, but also an integrated pattern projector.
As a result, both frame rate and image quality are optimized, and so significantly fewer resources are required on the PC used for analysis. The camera is designed for working distances of 180 mm to 3,000 mm and for variable picture fields depending on camera model. The available focal lengths of 6 to 16 mm can cover a wide range of distances and sizes. Unlike other 3D imaging processes, this camera can capture both stationary and moving objects with a frame rate of up to 30 fps.
This happens within milliseconds!
Despite having two sensors and an integrated projector, the camera only measures approx. 175 x 50 x 50 mm, and weighs just 550 g. Thanks to its robust aluminum housing and GPIO connector for 12-24 V hardware triggers, input and output, Ensenso N20 is perfectly equipped for industrial applications. It provides a wider field of view and is therefore also suitable for capturing larger volumes and for working distances of up to 3 meters. A more powerful projector with blue LEDs 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 permits cable lengths of up to 100 m and, because the camera is "powered over Ethernet" (PoE), there is no need for an additional cable for the power supply.
