Real-time 3D Stereo Vision in Color: Image Processing Performance Doubled

Nerian continues to push the boundaries of its 3D vision technology. This effort has resulted in the new firmware version 8.0 for Nerian’s SceneScan 3D vision system, which brings several major performance improvements.

The new firmware significantly increases the frame rate when used with color cameras. In some cases the frame rate is doubled, such as at 1024 x 768 pixels, where now 32 instead of 16 fps are possible with the full 256 pixels disparity range.

At the same time, the maximum supported color image resolution has been increased significantly, and is now on par with the maximum monochrome resolution. Here is the new list of recommended resolution / frame rate combinations:

Model Disparity Image Resolution
Range 640 × 480 800 × 592 1024 × 768 1600 × 1200 2016 × 1536
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

The new release also significantly increases SceneScan’s capacity for correcting lens distortion and camera alignment errors. As always, the firmware can be downloaded from our software download page.
