3D Measurement Performance with 2 Models
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.
Should SceneScan not meet your performance requirements, then our even more powerful Scarlet 3D depth camera might be the right choice for you.
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 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.
| Model | Disparity | Image Resolution | ||||
|---|---|---|---|---|---|---|

| SceneScan | 64 pixels | 45 fps | 30 fps | n/a | n/a | n/a |
| monochrome | 128 pixels | 30 fps | 20 fps | n/a | n/a | n/a |
| SceneScan Pro | 128 pixels | 135 fps | 90 fps | 55 fps | 22 fps | 13 fps |
| monochrome | 256 pixels | 75 fps | 53 fps | 34 fps | 12 fps | 7 fps |
| SceneScan Pro | 128 pixels | 80 fps | 53 fps | 32 fps | 13 fps | 8 fps |
| color | 256 pixels | 72 fps | 49 fps | 32 fps | 12 fps | 7 fps |
SceneScan
connects to our Karmin3 Stereocamera, or two standard USB3-Vision industrial cameras
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.
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 135 Fps and resolutions of up to 6 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.
SceneScan supports the USB3 Vision standard. This should allow all USB3 Vision compatible cameras to be used with a monochrome or color sensor. However, to ensure compatibility, we recommend using our Karmin3 stereo camera or cameras by Allied Vision.
We do not dictate with which software you have to use our devices. However, thanks to many compatibilities, we offer you a large selection for further image processing. Of course, you can also develop your own software.
