The inspection system, based on the use of computer vision techniques and infrared (IR) temperature measurements is able to:
measure the surface temperature distribution;
evaluate the overall surface quality;
drive the process control by suggesting modifications to the process parameters.
It faces surfaces inspection problems such as:
textured and high reflective surfaces;
moving surfaces;
great variety of defects both in size and appearance;
suitable sensitivity (minimum detectable size of 1 mm{2}.
The following advantages are available:
optimization of the strip quality;
automatic quality assessment;
improvements in process efficiency;
improvements in safety conditions (reduction of continuous human presence in the plant).
