Nerian SceneScan FPGA Stereo Vision Accelerator

SceneScan relies on stereo vision and hardware-accelerated image processing to gain a 3D understanding of an observed area. Unlike conventional depth sensing methods, stereo vision is a passive technology that does not require the emittance of visible or invisible light. This is why SceneScan provides accurate 3D depth measurements even in challenging situations, such as in bright daylight, far-range measurements, multiple overlapping sensors, or even under water.


SceneScan supports the USB3 Vision standard. Hence it can connect to any USB3 Vision compatible camera with a grayscale image sensor. In order to guarantee compatibility, however, we recommend using our own Karmin2 stereo camera or cameras by one of the following certified manufacturers: FLIR (formerly Point Grey), Basler, SVS-Vistek, The Imaging Source,Baumer.
