Although it seems that little time has passed, after 25 years, there have been considerable changes in the way and means of developing machine vision applications, the target of the applications and its problems. We will use a quality control application of negative electric accumulators (storage batteries) that we developed for Cegasa (Portable Energy) in 1994 for its Oñati factory as an example to illustrate it.

The application

This project had to control the distribution of the anode in the container of the batteries and automatically establish their horizontalness, the fill up level and check the absence of extra mass in the negative terminal, as all these issues could lead to short circuits with the insulation and the cathode
