In this example, we are inspecting a printed lot code on the bottom of a bottle. Due to the
reflective and concave characteristics of the bottom of the bottle, it is difficult to illuminate the
printed lot code without excessive specular reflections.
Figure 9 - Input images of the glossy vitamin bottle.
However, by using a DF198 MicroBrite
Diffuse
TM
Ring Light with each of its four quadrants
independently controlled with the DCS-400E Quad
Controller, we are able to capture four images with
illumination at the same angle of incidence, but
from multiple directions.
Using the Matrox Design Assistant and Imaging
Library (MIL) to process the images, the final
albedo of the image is flat – resulting in an easily
identifiable printed lot code.
