Karmin2 – The New Stereo Camera

Nerian introduces a successor to the successful Karmin stereo camera: Karmin2, a new model designed specifically for ease of use with our SceneScan stereo vision sensor.

Is it possible to improve good things over and over again? Is it possible to incorporate new ideas, new findings and new developments into the further development of the product? The start-up company Nerian Vision Technologies shows that even small companies are able to do this.

The Karmin stereo camera is a proven module for the FPGA-based Stereovision - systems SP1, SceneScan and SceneScan Pro and is already used in many different installations, to the full satisfaction of its users. Nevertheless, however, some wishes remained unfulfilled, such as improved mechanical stability and a more convenient connection to the above-mentioned systems. The former was taken into account with an extraordinary solid aluminium carrier part, which guarantees excellent mechanical stability and thus extremely stable calibration. Secondly, the new version Karmin2 can now be connected to the mentioned systems with only one USB 3 socket (instead of two) – this avoids cable clutter and is of course more ergonomic.

But why change features when they have proven themselves? Like its predecessor, the Karmin2 is still distinguished by different stereo base line distances, 10 and 25 cm. The 10 cm model is ideal for close-range depth measurements, with measuring distances up to 0.5 m. The 25 cm model, on the other hand, is designed for depth measurements from a greater distance. In this case, the higher base line allows better depth resolution at long distances.

A wide range of lenses is available for each version, enabling precise adjustment of the field of view. With our standard lenses, aperture angles between 25° and 62° are possible. Depending on the application, even larger or smaller angles can be achieved with special lenses. This makes Karmin2 the 3D depth camera with the largest configuration range on the market.

Both models are triggered by an external trigger signal, which guarantees excellent synchronization. The trigger signal can be generated by SceneScan or another signal generator. Accurate synchronization is essential when measuring moving objects.

And if, contrary to expectations, none of the two versions is possible: Nerian also offers cameras from other manufacturers, optimized for FPGA-based stereo vision systems SceneScan and SceneScan Pro!
