Nerian SceneScan Stereo Vision Sensor

SceneScan is Nerian’s latest 3D depth perception solution and the successor to our successful SP1 Stereovision Sensor. Using stereo vision and hardware-based image processing, SceneScan computes a 3D image of the observed environment in real-time. Unlike conventional depth cameras, no light in the visible or invisible spectral range needs to be emitted for this. As a result, SceneScan provides accurate 3D perception even under difficult conditions, such as bright daylight, long range measurements, overlapping ranges, or even underwater measurements.

Description

Processing performance

Two different models are available: SceneScan and SceneScan Pro. Both models provide identical features but differ in their processing capacity. Below you find an overview of the details.

SceneScan

SceneScan is a cost-optimized version for applications with less demanding requirements.

Supported image types: Monochrome

Max. greyscale resolution: 0.5 MP

Max. color resolution: —

Max. disparity: 128 Pixel

Max. frame rate: 45 fps*

SceneScan Pro

SceneScan Pro has the highest possible processing power and is therefore suitable for extremely demanding applications.

Supported image types: Monochrome

Max. greyscale resolution: 0.5 MP

Max. color resolution: —

Max. disparity: 128 Pixel

Max. frame rate: 45 fps*

Image Rectification

Horizontal displacement: -39 to +39 pixels

Vertical displacement: -39 to +39 pixels

Interpolation: Bilinear

The image data is processed in real time by using a powerful FPGA and our advanced stereo algorithm. The processing result is a sub-pixel accurate disparity map (an inverse depth image), which is transmitted via Gigabit Ethernet to a computer or embedded system. Our open source and cross-platform API converts this disparity map into a dense 3D point cloud. Our automatic recalibration ensures the functionality of the sensor system even under mechanical stress and a long operating time.

Depth measurement examples

By choosing a suitable camera setup, very different measuring ranges can be covered. Furthermore, it is possible to choose between a high frame rate or a high image or depth resolution. Frame rates of up to 100 Fps and resolutions of up to 3 megapixels are possible. This makes SceneScan the most flexible 3D sensor solution on the market. We are happy to support our customers by selecting the optimal configuration for their particular application.

The FPGA design, which is built into the SceneScan stereo vision sensor, can also be licensed as an IP core.

Supported Platform & Standard

SceneScan supports the USB3 vision standard. This allows all USB3 Vision compatible cameras to be used with a monochrome or color sensor. However, to ensure compatibility, we recommend using our Karmin3 or Karmin2 stereo camera, or cameras from one of the following approved manufacturers:

FLIR (formerly Point Grey), Basler, SVS-Vistek, The Imaging Source, Baumer.
