Karmin2 – Our 3D Stereo Camera

Karmin2 is the latest revision of our successful Karmin stereo camera. Karmin2 has been specifically designed for easy integration with our SceneScan stereo vision sensor. In combination with SceneScan, Karmin2 becomes a fully featured 3D depth camera that acquires accurate range measurements, even in bright light conditions and over long distances.

Karmin2 stereo camera

Karmin2 is available in two different stereo baseline distances: 10 and 25 cm. The 10 cm model is ideal for close range depth measurements, with measurement distances as low as 0.5  m. The 25 cm model, on the other hand, is intended for long range stereo vision. In this case, the wider baseline facilitates a superior depth resolution at higher distances.

A large selection of lenses is available for each version, which allows for a fine-grained control of the field-of-view. With our standard lenses, field-of-views between 25° and 62° are possible. Even wider or narrower angles can be achieved with special lenses if the application requires so. This makes Karmin2 the most configurable 3D depth camera on the market.

SceneScan with attached Karmin2 stereo camera

Karmin2 is machined from a solid, massive piece of aluminum, which provides excellent mechanical stability and ensures a long-lasting calibration. Its two image sensors have a native resolution of 1600 × 1200 pixels, but can also be operated at 800 × 592 pixels at an increased frame rate.

Both cameras are triggered though an external trigger signal, which provides excellent synchronization. The trigger signal can be generated by SceneScan or another signal generator. An accurate synchronization is imperative when acquiring depth measurements of moving objects.

Recommended Configurations with SceneScan / SceneScan Pro

Below you find a list of recommended configurations when using Karmin2 in combination with SceneScan or SceneScan Pro for stereo vision. Please select a Karmin2 and SceneScan model to update the list.
