English to French Tech/Engineering Patents (in a patent) system for detecting defects in painting of components of motor-vehicle bodies

In the case of monitoring painting quality of motor-vehicle bodies, there still arises the need of detecting various types of vehicle body
painting defects, substantially classifiable in three categories: small defects, such as for
example small spots, medium defects, such as for example "orange peel" effects, and large defects, such as for example paint dripping on the edges of the vehicle body.
