Abstract

In order to achieve better quality on their products, manufacturers now use more and more artificial vision systems during their process. Concerning transparent objects the task is not trivial and requires controlling the whole lighting of the scene. This paper deals with a polarization imaging method and its application to shape measurement of transparent objects. Our aim is to develop a low cost system based on a unique viewpoint and using industrial components. We show how to overcome ambiguities appearing during the measurement process.
