Illuminator for embedded inspection camera


Piseo

 

Systems of machine vision are becoming more and more widespread and one can find many commercially ready-to-use cameras and lenses.
Nevertheless, the software for processing captured images, even very elaborate, do not always succeed in discriminating sufficiently the scenes because of an ill-adapted illumination.
By using a properly designed and realized illuminator, it is possible to compensate for lens vignetting problems, colorimetry and scene uniformity.

 


Application

Inspection of mechanical structures by means of a drone.

 

Objective

Design of an illumination system to compensate vignetting due to the lens of the camera and thus improve the overall performance of the inspection system (efficiency, date reliability).
