Advanced vision approach applied to non-contact micro-measurements: a practical application

In micro-world applications usually the need to manipulate, handle and measure micro-components becomes an important issue both for production and research reasons. Pointing out the aspect of measurements, the specific contest considerably conditions the technical approach and practical procedure which can be efficiently applied to obtain a reliable and precise measure. The framework of this research concerns the production phase of micro-biomedical components characterized by very small dimensions, high deformability, and sensitivity of surface damage. The main focus has dealt with the definition of an optical procedure to orient and assemble micro-elements. The compromise between the production cadence and the measurement necessity has been one of the main requirements for the research in order to define, implement, and evaluate an ad hoc process to get the expected outcomes. The proposed procedure allows to solve a practical issue by combining a solid vision background to a technical contest solving the specific measuring task and applying the same approach to different practical applications, both in micro and macro world.
