lighting intensity [PickMaster 3]

hi, all

Is any effect for the pick and place aplication, if there are some differences in lighting intensity? ( for example : we assembly and program in factory, and then we move the system in… , let’s say an exhibition, which many lamps, and the lighting intensity is increase)

If it does, i think one of the solutions is from mechanic. MAke the mechanic doesn’t so tranparent. Is it right? or any other idea?

thank you

Hi,

Different vision models and products have varying robustness against light variations.
For example a geometric model (PatMax) is normally much more robust than a blob model.

The lighting for the vision task should always be controlled.
There are several ways of doing this depending on the task, but here are two examples:

  1. Shield out ambient light by mounting the camera in a “light hub”. The light hub is an enclosure that contains its own light source. Normally, a good approach is to use one or several diffuse light sources inside the box and to use white matt inner walls. This creates an even light distribution on the product.

  2. Another approach is to use an Infra-Red filter on the camera and an Infra-Red light source. This will shield out visible ambient light and (almost) only the light from the IR-light source will be reflected by the product.

I don’t have any special recommendation, but here you can see some examples:
