Diseño e implementación de un sistema automático de detección y perforación de marcas en láminas de PVC utilizando técnicas de visión artificial para el Instituto Geográfico Militar del Ecuador

Abstract

This project presents an automatic system for detection and perforation of marks on PVC sheets. The system automates a stage of IDs production process at Instituto Geográfico Militar (IGM). Marks detection is done using computer vision techniques, segmentation techniques specifically. System is set up on a cutting plotter that allows positioning over the PVC sheets surface. Perforation is done by a rotary tool with an extension shaft, also set up on the plotter. The system recognizes circular marks captured by a digital camera (set up to the plotter), to calculate, afterwards, the perforation position. The results obtained from the system functioning in the production plant show a precision in the perforation position of ±0.23mm, being ±1mm the permitted error for this task. The reached precision with this machine is evidence of the utility and penetration ability of computer vision in the industry.
