Due to the growing demand for capsules containing liquid drugs in order to facilitate their ingestion, there is an increasing need for a machine vision system that offers a solution to inspect and guarantee the quality of the product.

Before finding the solution for the implementation of the system it is necessary to analyze the samples and decide which are the defects that should be considered and with what precision, in this case:
- Wrong reference. (1)
- Empty capsule. (2)
Identification of defects
Once the defects to be detected have been defined, a machine vision system is designed and implemented to carry out the analysis of these capsules. It has different components, including the acquisition device and the lighting, essential elements to acquire the image that must be analyzed later.

By means of the analysis and control carried out by the system, it is possible to reduce the number of defective products that circulate in the station, consequently reducing the responsibility that falls on the operator and providing a very high and constant reliability to the inspection.
