Backlights for retro-illuminated conveyor belts  - VELTRU AG

Description

Get reflection free contour images with excellent contrast. The slim design of just 20mm simplifies the integration into conveyor belts. The flicker free dimming allows gently controlling the scene. On the right hand side, an original picture of a flow-wrapped syringe with disturbing reflections on the film and the same syringe under the backlight. It is even possible to detect content or packaging, just as needed. Backlights also work well with modular belts or wire mesh conveyors, as long as the products are bigger than the mesh pattern size. On the images here below: Top left the products on the modular belt, top right in black and white. Bottom left the same view as seen by the camera and bottom right after having removed the modular belt with some standard vision algorithm steps.
