Bin picking applications are currently the most requested applications in the field of automation technology. Which is not a surprising fact, because a solidly programmed solution saves time and money and will amortize its implementation in a very short time.

A bin picking solution is only considered attractive as long as it is affordable, easy to use, precise and fast. Additionally there are some main challenges such as occlusion, bad lighting conditions, reflections or smooth and textureless surfaces, which have to be taken into consideration while planning a bin picking application.

To improve the performance of applications, the new passive stereo vision image processing system can be combined with a pattern projector. The pattern projector is delivered in an additional package and is not mounted on Nerian Vision's 3D stereo vision system itself or on the stereo camera. This allows to decide how and where the projector should be mounted. For example, in such a way that it does not blind the 3D stereo camera during operation when reflective surfaces need to be measured.

The projector can be used at different angles as long as it illuminates the desired field of view well. In addition, thanks to several stereo camera models and baseline distances, different measuring distances are conceivable – because our systems adapt to your application, not the other way around. Another advantage is that different wavelengths of light can be emitted to get the best results from the application.
