The described problem is a diagnostic task which must be solved for high-velocity industrial machine tools. Due to environmentally degraded conditions, direct measurements are not possible. Due to the rapidity of the machine, human intervention is not possible in case it causes positional faults. So, an oriented vision solution is proposed. The degraded conditions are vibrations, projections of water and metal chips, dazzling, etc. In this case, there is only one problem that is unable to achieve a diagnostic solution: is it the right piece in the right place? That is why complementary methods are proposed and presented in this paper to answer this question.
