Its extensive collection includes thousands of spectroscopic and photographic glass plates, which were collected between the early 1900s and the 1980s by eminent Argentine astronomers. These plates represent a unique and valuable record that remains largely unpublished. In 2019, the Recuperation of Historical Observational Work (ReTrOH, for its initials in Spanish) project initiated a digitization programme to convert over 15,000 plates from the collection into digital format. Given that the manual processing of these plates is intricate, error-prone, and time-consuming, a multidisciplinary team of astronomers and computer scientists was assembled to create a software tool called PlateUNLP. This tool was specifically designed to streamline the digitization process, enhancing efficiency and reducing the potential for errors. PlateUNLP utilizes advanced signal processing and computer vision techniques to automatically identify and isolate each spectrum captured on the plates, attaching the relevant metadata and thus limiting the need for manual intervention. The system is released as open-source software, allowing for broad accessibility. While PlateUNLP was tailored to meet the demands of the ReTrOH project, its adaptable design makes it suitable for digitizing many other plate collections around the world.Attribution 4.0 International LicenseCCS Concepts: Applied computing → Astronomy; PhysicsApplied computing → AstronomyPhysics10.2312/gch.202412434 pages
