SceneScan Stereo Vision Sensor
3D Measurement Performance with 2 Models
SceneScan: Depth-sensing through stereo vision at 100 fps
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.
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 is a cost-optimized version for applications with less demanding requirements.

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 with 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.
The maximum frame rate depends on the selected image resolution and depth resolution (the disparity range). We recommend using one of the following configurations. However, other configurations are also possible.
|Range||640 × 480||800 × 592||1280 × 960||1600 × 1200|
|SceneScan||64 pixels||45 fps||30 fps||n/a||n/a|
|monochrome||128 pixels||30 fps||20 fps||n/a||n/a|
|SceneScan Pro||128 pixels||100 fps||65 fps||24 fps||15 fps|
|monochrome||256 pixels||70 fps||45 fps||15 fps||10 fps|
|SceneScan Pro||256 pixels||45 fps||27 fps||9 fps||6 fps|
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:
