Lighting optimisation for empties identification


Single bottles

Different types of bottles made from various materials (for example glass and plastics) and presenting different colours are to be identi­fied safely.

By varying the lighting conditions (light direction, light colour, luminance, structure, etc.), the reliability of the identification process can be enhanced.

Bottle crates

The identification of the content of bottle crates turns out to be difficult because of their different colours and geometrical shapes. The bottles as well can differ greatly (e.g. in size, colour, material, with or without bottle top).

For the identification of the crate and its contents, the method of edge detection is applied. For this, contrasts must be generated in the image through lighting.
